CA2177038A1 - Lotion composition for imparting soft, lubricious feel to tissue paper - Google Patents

Abstract

A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from 5 to about 15 % by weight. The lotion composition comprises plastic or fluid emoilient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an agent such as sorbitan stearates or N-cocoyl, N-methyl glucamide to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

BACKGROIJND OF T~F INVFNI~ON
Cleansing the skin is a personai hygiene problem not aiways easily solved. Of course, the common procedure of washing the skin with soap and water works well, but at times may be either unavailable or ~. to use. While soap and water cou~d be used to clean the perianal region af~er defecation for example, such a procedure would be extremely iJUId. .l~v~
Dry tissue products are therefore the most comrnoniy used post-defecation anai cleansing product. These dry tissue products are usually referred to as "toilet tissue" or "toilet paper."
The perianal skin is marl~ed by the presence of fine folds and wrinkies (sulci) and by hair follicles, both of which make the perianai region one of themore difficult anatomicai areas l:o cleanse. During defecation, fecai matter is excreted through the anus and tl:nds to accumuiate in hard to reach locations such as around the base of hairs and in the sulci of the skin's surface. As the fecal matter dehydrates upon exposure to the air, or upon contact with an absorbent cleansing implement s.uch as tissue paper, it adheres more 3 5 tenaciously to the skin and hair, thus making subseciuent removal of the remaining dehydrated soil even Inore difficult.
_ , _ _ _ _ _ . . _ .. ... . . ..

2 1 7 7 0 3 8 Pcr~s94/l3674--Failure to remove fecal matter from the anal area can have a deleterious effect on personal hygiene. The fecal matter remaining on the skin af~er post-defecation cleansing has a high bacterial and viral content, is malodorous and is generally dehydrated. These ~,114.~.,L~I iali~,a increase the 5 likelihood of perianal disorders and cause personal discomfort (e.g., itching, irritation, chafing, etc.). Further, the residual fecal matter stains ulld~ a and causes unpleasant odors to emanate from the anal region.
Thus, the rl~nCPql l~on~ eC of inadequate perianal cleansing are clearly u~ LLI~-,Liv~:.
For those individuals suffering from anal disorders such as pruritis ani, ~,.. ,.,I.. ;.I~fissures,cryptitis,orthelike,theimportanceofadequate perianal cleansing takes on heightened c ~ . Perianal disorders are usually ..I.~ .~.,L~ l by openings in the skin through which the bacteria and viruses in the residual fecal matter can readily enter. Those people affLicted 15 with anal disorders must, therefore, achieve a high degree of perianal cleansing after defecation or risk the likely result that their disorders will be aggravated by the bacteria and viruses remaining on the skin.
At the same time anal disorder sufferers face more severe c. .~ from insufficient post defecation cleaning, they have greater 20 difficulty in achieving a satisfactory level of soil removal. Anal disorders generally render the perianal region extremely sensitive and attempts to remove fecal matter from this region by wiping with even normal wiping pressure causes pain and can further irritate the skin. Attempts to improve soilremoval by increasing the wiping pressure can result in intense pain.
25 Conversely, attempts to minimize discomfort by reducing the wiping pressure result in an increased amount of residual fecal matter lefl on the skin.
Cu~ dl toilet tissue products used for anal cleaning are essentially dry, high density tissue papers that rely exclusively on mechanical processes to remove fecal matter from the perianal skin. These ~,UIl~ ti 30 products are rubbed against the perianal skin, typically with a pressure of about I psi (7 kilopascals) and basically scrape or abrade the fecal matter fromthe skin. After the first few wipes, the upper portion of the soil layer is removed because the wiping process is able to overcome the soil-soil cohesive forces that exist within the fecal matter. A cleavage is thereby created in the 35 soil layer itself with the upper portion of the fecal layer being removed and the lower portion of the soil remaining adhered to the perianal skin.

WO 95/16824 ,, PCT/[JS94113674 Cu~ io~ldl tissue products are absorbent and with each successive wipe the fecal matter becomes i..~ a;ll~ly dehydrated, causing it to adhere more tenaciously to the perianal skin and hair and making itâ removai difticult in the extreme. Pressing the tisslie forcefully against the perianaii skin will 5 remove more ofthe fecal mattel but is intensely painirul for people sufl'eringfrom anai disorders and can exc~riate even normal perianal skin, potentially causing irritation,; n~ "" pain, bleeding, and infection.
Irritation and i " ~ - ~ ;u ~ potentially caused by the use of tissue products is not limited to toilet ~:issue. Facia'i tissue products used to wipe and 10 remove nasal discharges associated with colds, flu and allergies can also cause such problems. In addition to difficulties in breathing, seeing, and talking, anindividual affiicted with these disorders frequently has a sore and irritated nose. The nose, as well as the ~u. i uu..~i;..b tissue, e.g., upper lip area, are oflen red and inflamed to the extent of becoming painirul in extreme cases.
15 This iri-itation, ;.. 1~.,.. li~.,~ and redness can have severai causeâ. A
prime one is, of course, the sheer necessity of frequently blowing one's nose into the tissue, and wiping the r~~sultant nasal discharge from the nose and ~u, uu.-~ area. The degree of iri-itation and n ' caused by such blowing and wiping is directly j~Jl.UIJOli' I to: (I) the surface roughness of the tissue used; and (2) the numl~er of times the nose and its ~u. ,, " ~ areas are in contact with the tissue. A tissue that is relatively weak or relatively nù"~ ",L requires a greater number of contacts with the face than a stronger or more absorbent tissue that is able to contain a greater quantity of nasal discharge.
There have been numerous previous attempts to reduce the abrasive effect of toilet and facial tissues and to increase their softness impression. One common approach is by mechani.cal processing. By using particular processing steps during rzr~nnzki~g, toilet and facial tissue products can be made that are softer and less iri-itating. Examples of tissue products that are ' "~, processed to be so~er are shown in U.S. Patent 4,300,981 (Carstens), issued November, 1 /', 1981, as well as the various patents discussed in its ~
Besides mechanical proc~ssing, others have applied emollients, saives, cleansing agents, and the like to tissue products to enhance not oniy the cleaning of the skin but also to reduce irritation and n This reduction in irritation and n ' jS typically achieved through either the lubricity of the substance applied to the tissue or through the therapeutic W095tl6824 2 1 77038 pCTlUS94/13674 --action of the substance itself This approach is illustrated in U. S. Patent 4,112,167 (Dake et al) issued September, 5, 1978, particularly in regard to toilet tissues. See also in U.S. Patent 3,896,807 (Buchalter), issued July 29, 1975 and in U.S. Patent 3,814,096 (Weiss et al), issued June 4, 1974 for 5 other examples of this approach.
One substance that has been applied as a lotion to tissue products to impart a soothing, lubricious feel is mineral oil. Mineral oil (also known as liquid petrolatum) is a mixture of various liquid l~ u al~ons obtained by distilling the l ,,' ~ ,, (i.e., 300-390C) fractions in petroleum. Mineral 10 oil is liquid at ambient t."-~ u-.,~, e.g. 20-25C. As a result, mineral oil is relatively fluid and mobile, even when applied to tissue products Because mineral oil is fluid and mobile at ambient t.".".,~u..,~, it tends not to remain localized on the surface of the tissue, but instead migratesthroughout. Accordingly, relatively high levels of mineral need to be applied to the tissue to provide the desired softness and lotion-like feel benefits.
These levels can be as high as about 22-25 wt. % of the tissue product. This leads not only to increased costs for these lotioned tissue products, but other detrimental effects as well.
One of these detrimental effects is a decrease in tensile strength of the tissue product. As mineral oil migrates to the interior of the tissue, it tends to act as a debonding agent, thus decreasing the tensile strength of the product.
This debonding effect becomes more ~,. u~uu~,ed as the level of mineral oil applied is increased. Increasing the level of mineral oil applied can also adverse~y affect the caliper of the tissue product.
EYen without increasing its leYel, the tendency of mineral oil to migrate once applied has other detrimental effects. For example, the applied mineral oil can transfer to, into and through the packaging or wrapper material for the lotioned toilet tissue product. This can create the need for barrier-type packaging or wrapper films to aYoid smearing or other leakage of mineral oil from the tissue product.
Accordingly, it would be desirable to provide lotioned tissue products that: (I) have a desirable soothing, lubricious feel; (2) do not require relatively high levels of mineral oil: (3) do not adversely affect the tensile strength and caliper of the product; and (4) do not require special wrapping or barrier materials for packaging.
DISCLOSURE OF THE INVENTION

WO 9~116824 , PCTIU~94/13674 The present invention relates to a lotion c,~ that is semisolid or solid at ambient ~ lul~a (i.e., at 20C) and imparts a soft, lubricious, lotion-like feel when applied to tissue paper. This lotion c.... ,l.~ ;.. , comprises:
(A) from about 20 to about 95% of a ~ water free emollient having a plastic or fluid ,ulla;a~ ,y at 20C and comprising a member selected from petroleum-based emollients, fatty acid ester emollients, alkyl ethoxylate emollients, and mixtures thereof; and (B) from about 5 to about 80% of an agent capable of ;..., ....I,il;,:.~ the emollient on the surface of tissue paper trl~ated with the lotion ~ the agent having a melting point of at least about 40C and comprising a member selected from pol~h~J. u~ fatty acid esters, pulyh~d.u~ fatty acid amides, and mixtures thereof, wherein the pûl~ u~
moiety of the ester or amide has at least two free hydroxy groups; and (C) optionally from about 2 to about 50% of a hydrophilic surfactant having an HLB value of at least about 7.
The present invention further relates to lotioned tissue papers wherein the lotion, . - is applied to at least one surface thereof in an amount of from about 2 to about 20% by weight of the dried tissue paper. Lotioned tissue papers according to the present invention have a desirable, lubricious, 25 lotion-like feel. Because the emollient is cllhct~nr~ y ' ' ' on the surface of the tissue paper, less lotion ~ is needed to impart the desired soft, lotion-like feel. As a result, the detrimental efîects on the tensile strength and caliper of the tissul~ caused by prior mineral oil-containing lotions can be avoided. In addition, special barrier or wrapping materials are 30 I y in packaging the lo~i~ned tissue products of the present invention.

As used herein, the term "cv~ nia;ll~" means that the various ~...",l,u ~, ingredients, or steps, can be conjointly employed in practicing thepresent invention. Accordingly, the term ~ICv~ the more restrictive terms "consisting essentially oP' and "consisting o"
All p~,..,~i..L"~, ratios and ~lu~olLio.~s used herein are by weight 15 unless otherwise specified.
A. Tissue Papers The present invention is useful with tissue paper in general, including but not limited to cv.... ' - "y felt-pressed tissue paper; high bulk pattern 20 densified tissue paper; and high bulk, l , ~ J tissue paper. The tissue paper can be of a 1` ` 'b. '- " '` or multi-layered co..~;~u.,LiV~, and tissue paper products made therefrom can be of a single-ply or multi-ply ~.v..~L. u~,~iv... The tissue paper preferably has a basis weight of between about 10 g/m2 and about 65 glm2, and density of about 0.6 g/cc or less. More preferably, the basis weight will be about 40 glm2 or less and the density will be about 0.3 g/cc or less. Most preferably, the density will be between about 0.04 glcc and about 0.2 glcc. See Column 13, lines 61-6~, of U.S. Patent 5,059,2~2 (Ampulski et al), issued October 22, 1991, which describes how the density of tissue paper is measured. (Unless otherwise specified, all amounts and weights relative to the paper are on a dry basis.) Cv.,~. "y pr~ssed tissue paper and methods for making such paper are well known in the art. Such paper is typically made by depositing a IJa~J.,.lll~ki.~, furnish on a foraminous forming wire, often referred to in the art as a Fourdrinier wire. Once the urnish is deposited on the forming wire, it is referred to as a web. The web is dewatered by preSsing the web and drying at elevated i , ...lu.~:. The particular techniques and typical equipment for making webs according to the process just described are well known to those WO 9!5/16824 PCTIUS94/13674 skilled in the art. In a typical pl~ocess, a low consistency pulp fumish is provided from a pressurized headbox. The headbox has an opening for delivering a thin deposit of pulp furnish onto the Fourdrinier wire to fomm a wet web. The web is then typically dewatered to a fiber ~,ulla;alell.,y of 5 between about 7% and about 25% (total web weight basis) by vacuum dewatering and further dried by pressing operations wherein the web is subjected to pressure deveioped by opposing mechanicai members, for example, c-ylindricai rolls. The dewatered web is then further pressed and dried by a steam drum apparatus known in the art as a Yankee dryer.
Iû Pressure can be developed at the Yankee dryer by mechanical means such as an ûpposing cylindrical drum pressing against the web. Multiple Yankee dryer drums can be employed, where~y additional pressing is optionally incurred between the drums. The tissue paper structures that are fommed are referred to hereafter as conventional, pressed, tissue paper structures. Such sheets are . 15 considered to be compacted since the entire web is subjected to substantialmechanical ~,u~ lcaa;ullGl forces while the fibers are moist and are then dried while in a l,UIll~JI.;.ac;~i state.
Pattern densified tissue paper is ~ G~le~ ,d by having a relatively high bulk field of relatively low fiber density and an array of densified zones of 20 relatively high fiber density. The high bulk field is allC"lGl;~
as a field of pillow regions. The densified zones are ' ~Iy referred to 2s knuckie regions. The densified zones can be discretely spaced within the high bulk field or can be ;..~ cul.~ lc~i, either fully or partially, within thehigh bulk field. The pattems can be fommed in a "û..u~ ' c~.liould~;o or can be formed so as to provi~le an omamental design(s) in the tissue paper.
Preferred processes for making pattem densified tissue webs are disclosed in U.S. Patent No. 3,301,746 (Sanford et al), issued January 31, 1967; U.S.
Patent No. 3,974,025 (Ayers), issued August lû, 1976; and U.S. Patent No.
4,191,6û9 (Trokhan) issued March 4, 1980; and U.S. Patent 4,637,859 (Trokhan) issued January 2û, 1987; all of which are i.,.,u- lJuldled by reference.
In general, pattem densified webs are preferably prepared by depositing a ~ Gi~ o fumish on a foraminous fomling wire such as a Fourdrinier wire to fomn a wet ~veb and then j". l..l..,~:..g the web against anarray of supports. The web is pressed against the array of supports, thereby 35 resulting in densified zones in the web at the locations O c,~ , ' "y ~,ul I ~,~p~ iillo to the points of contact between the array of supports and the wet web. The remainder of the web not co...~,. caacd during this operation is wo 95/16824 2 1 7 7 0 3 ~ Pcr/uss4ll3674 referred to as the high bulk field. This high buik field can be further dedensifled by application of fluid pressure, such as with a vacuum type device or a blow-through dryer, or by ' "~ pressing the web against the array of supports. The web is dewatered, and optionally predried, in such a manner 5 so as to aubaLG~ avoid CU..~ caa;ul~ of the high bulk field. This is preferably ~ by fluid pressure, such as with a vacuum type device or blow-through dryer, or alternately by .,... 1.- .;.. "~ pressing the web against an array of supports wherein the high bulk fleld is not cù~ l. The operations of dewatering, optional predrying and formation of the densified zones can be integrated or partially integrated to reduce the total number of processing steps performed. S~~hs~ n' to formatiûn of the densified zones, dewatering, and optional predrying, the web is dried to comrieticm~ preferably still aYoiding mechanical pressing. Preferably, from about 8% to about 55%
of the tissue paper surface comprises densified knuckies having a relative density of at least 125% of the density of the high bulk field.
The array of supports is preferably an imprinting carrier fabric having a patterned ~ of knuckles that operate as the array of supports that facilitate the formation of the densified zones upon application of pressure.
The pattern of knuckies constitutes the array of supports previously referred to. Suitable imprinting carrier fabrics are disclosed in U.S. Patent No.

3,301,746 (Sanford et al), issued January 31, 1967; U.S. Patent No.
3,821,068 (Salvucci et al), issued May 21, 1974; U.S. Patent No. 3,974,025 (Ayers), issued August 10, 1976; U.S. Patent No. 3,573,164 (Friedberg et al.), issued March 30, 1971; U.S. Patent No. 3,473,576 (Amneus), issued October 21, 1969; U.S. Patent No. 4,239,065 (Trokhan), issued December 16, 1980; and U.S. Patent No. 4,528,239 (Trokhan), issued July 9, 1985, all of which are ~Ju~ ed by reference.
Preferably, the furnish is first formed into a wet web on a foraminous forming carrier, such as a Fourdrinier wire. The web is dewatered and transferred to an imprinting fabric. The furnish can alternately be injtiaily deposited on a foraminous supporting carrier that also operates as an imprinting fabric. Once formed, the wet web is dewatered and, preferably, thermally predried to a selected fiber COIIa;a~ ,.y of between about 40% and about 80%. Dewatering is preferably performed with suction boxes or other vacuum devices or with blow-through dryers. The knuckle imprint of the imprinting fabric is impressed in the web as discussed above, prior to drying the web to completion. One method for ~, , ' ' _ this is through WO 9Y16824 2 1 7 7 ~ 3 8 PCT/US94113674 application of mechanical pressllre. This can be done, for example, by pressing a nip roll that supports the imprinting fabric against the face of a drying drum, such as a Yankee dryer, wherein the web is disposed between the nip roll and drying drum. Also, preferably, the web is molded against the 5 imprinting fabric prior to completion of drying by application of fluid pressure with a vacuum device such as a suction box, or with a blow-through dryer.
Fluid pressure can be applied to induce impression of densified zones during initial dewatering, in a separate, subsequent process stage, or a thereo r,.. ,~ i, nonpattern-densified tissue paper structures are described in U.S. Patent No. 3,~12,000 (Salvucci et al), issued May 21, 1974 and U.S. Patent No. 4,208,459 (Becker et al), issued June 17, 1980, both of which are ill~ul~Jul~Lc I by reference. In general, ~ ,. u ~ i, nonpattem-densified tissue paper structures are prepared by depositing a p ~
5 fiumish on a foraminous fomming wire such as a Fourdrinier wire to fomm a wet web, draining the web and removing additional water without mechanical l~Ulllyl~ until the web has a fiber COIla;~Ltll~ of at least about 80%, and creping the web. Water is removed from the web by vacuum dewatering and themmal drying. The resulting structure is a soft but weak, high bulk sheet of 20 relatively ~ v...~ 1 fibers. Bonding material is preferably applied to portions of the web prior to creping.
Compacted non-pattem-densified tissue structures are commoniy known in the art as cv.... I tissue structures. In general, compacted, non-pattern-densified tissue paper structures are prepared by depositing a 25 I)dy. ~ ~ filmish on a foraminous wire such as a Fourdrinier wire to form a wet web, draining the web and removing additional water with the aid of a unifomm mechanical c~ ;-- . (pressing) until the web has a LVlla; .L~ of 25-50%, Ll '' lg the web to a themmal dryer such as a Yankee and creping the web. Overall, water is removed from the web by vacuum, mechanical 30 pressing and themmai means. The resulting structure is strong and generally of singular density, but very low in bulk, absorbency and sofrness.
The p~ fibers utilized for the present invention will nommally include fibers derived from wooli pulp. Other cellulosic fibrous pulp fibers, such as cotton linters, bagasse, etc., can be utilized and are intended to be 3 ~ within the scope of this inventioll. Synthetic fibers, such as rayon, p~ Ll.;h,..e and ~,c,l~"u~ ne fibers, can also be utilized in ~U"'~ ' with WO 95116824 2 l 7 7 0 3 8 PCTIIJS94113674 natural cellulosic fibers. One exempiary polyethylene flber that can be utilizedis Pulpex~, available from Hercules, Inc. (Wilmington, Delaware).
Applicabie wood pulps include chemical pulps, such as KraR, sulfite, and sulfate pulps, as well as mechanical pulps includin~, for example, 5 ~5~vu~iwood, ~ . -l pulp and chemically modified ~h~ l pulp. Chemical pulps, however, are preferred since they impart a superior tactile sense of soRness to tissue sheets made therefrom.
Pulps derived from both deciduous trees (hereaRer, also referred to as "hardwood") and coniferous trees (hereaRer, aiso referred to as "softwood") 10 can be utilized. Aiso useful in the present invention are fibers derived fromrecycled paper, which can contain any or all of the above categories as weil as other non-fibrous materials such as fillers and adhesives used to facilitate theoriginal p~,u~,,,.~,iu..~,.
In addition to 1~ , fibers, the U~ IIIaiUIIg furnish used to 15 make tissue paper structures can have other ---1i or materials added thereto as can be or later become known in the art. The types of additives desirable will be dependent upon the particular end use of the tissue sheet t~ t. ~I For example, in products such as toilet paper, paper towels, facial tissues and other similâr products, high wet strength is a desirable 20 attribute. Thus, it is oRen desirable to add to the p~,.,. ' ~ furnish chemicai substances known in the art as "wet strength" resins.
A general dissertation on the types of wet strength resins utilized in the paper art can be found in TAPPI monograph series No. 29, Wet Strength in Paper and Paperboard, Technical Association of the Pulp and Paper Industry (New York 1965). The most useful wet strength resins have generally been cationic in character. For permanent wet strength generation, polyamide-~,llu~ vh~ resins are cationic wet strength resins have been found to be of particular utility. Suitable types of such resins are described in U.S. Patent No. 3,~00,623 (Keim), issued October 24, 1972, and U.S. Patent No.
3,772,076 (Keim), issued November 13, 1973, both of which are ;Il~,ull~OlaL~ i by reference. One commercial source of a useful p~ c,.;"hiv.u~,, ~i, ;., resin is Hercules, Inc. of Wilmington, Delaware, which markets such resins under the mark Kymene~9 557H.
r~l~a.,, ~, ' resins have also been found to be of utility as wet strength resins. These resins are described in U.S. Patent Nos. 3,556,932 (Coscia et al), issued January 19, 1971, and 3,556,933 (Williams et ai), issued January 19, 1971, both of which are ~,u.~ i herein by reference. One .

4 2~77~3~ Pcrlllss4/l3674 Il commercial source of polyacrylamide resins is American Cyanamid Co. of Stamford, ('onnPrtir~lt~ which markets one such resin under the mark Parez~
631 NC. =.=
Still other water-soluble cationic resins finding utility in this invention

5 are urea ru~ ald~ rJ~, and melamine rullllalJ~ dc resins. The more common functional groups of these polytunctional resins are nitrogen containing groups such as amino groups and methylol groups attached to nitrogen.
rUlJ~;h,~,.;...;.~ type resins can also find utility in the present invention. In addition, temporary wet strength resins such as Caldas 10 (lllalluL,~ulcJ by 10 Japan Carlit) and CoBond 1000 (Illallura~,luleJ by National Starch and Chemical Company) can be used in the present invention. It is to be understood that the addition of chemical compounds such as the wet strength and temporary wet strength resins discussed above to the pulp furnish is optional and is not necessary for the pra~ tice of the present invention.
In addition to wet strength additives, it can also be desirable to include in the ~a~ Ll.~ fibers certain dry strength and lint control additives known in the art. In this regard, starch binders have been found to be particularly suitable. In addition to reducing linting of the finished tissue paper product, low levels of starch binders also impart a modest improvement in the dry 20 tensile strength without imparting stiffness that could result from the addition of high levels of starch. Typically the starch binder is included in an amount such that it is retained at a ievel of from about 0.01 to about 2%, preferably firom about 0.1 to about 1%, by weight of the tissue paper.
In general, suitable starch binders for the present invention are 25 ~,llala~.leli~_~ by water solubilit)~, and lyJlu~ .y. Although it is not intended to limit the scope of suitable starch binders, . .,~ alivc starch materials include corn starch ami potato starch, with waxy corn starch known industrially as amioca starch beilng particularly preferred. Amioca $arch differs from common corn starcll in that it is entirely a~ )pe-Lill~ whereas 30 common corn starch contains both al.l,!o~_Li., and amylose. Various unique characteristics of amioca starch are further described in "Amioca - The Starch From Waxy Corn", H. H. Schopmeyer, Food Industries, December 1945, pp.
106-108 (Vol. pp. 1476-1478).
The starch binder can be in granular or dispersed form, the granular 35 form being especially preferred. The starch binder is preferably sufficiently cooked to induce sweiiing of th~: granules. More preferably, the starch granules are swollen, as by cooking, to a point just prior to dispersion of the ;

.. . ..

WO 95/16824 2 l 7 7 0 3 8 PCT/I~S94113674 starch granule Such highly swollen starch granules shall be referred to as being "fully cooked." The conditions for dispersion in general can vary depending upon the size of the starch 5ranules, the degree of .. y " ~/ of the granules, and the amount of amylose present. Fully cooked amioca starch, 5 for example, can be prepared by heating an aqueous slurry of about 4%
consistency of starch granules at about 190F (about 88C) for between about 30 and about 40 minutes. Other exemplary starch binders that can be used include modified cationic starches such as those modified to have nitrogen containing groups, including amino groups and methylol groups attached to 10 nitrogen, available from National Starch and Chemical Company, (Blil5., ~.L~" New Jersey), that have previously been used as pulp furnish additives to increase wet and/or dry strength.
B. Lotion Comrosi~ion The lotion ~ c of the present invention are solid, or more often semisolid, at 20C, i.e. at ambient It~ ,.alul~. By "semisolid" is meant that the lotion .., - ~ ;-,- has a rheology typical of 1,~ J~ or plastic fluids. When no shear is applied, the lotion ~....1..,~:l;.. - can have the appearance of a semi-solid but can be made to flow as the shear rate is 20 increased. This is due to the fact that, while the lotion ~ 11 contains primarily solid ~.u ,l.., : ~, it also includes some minor liquid C
By being solid or semisolid at ambient ~ UI~ these lotion Culll~Ju l;liulla do not have a tendency to flow and migrate into the interior of the tissue web to which they are applied. This means less lotion ~
25 is required for imparting softness and lotion-like feel benefits. It also means there less chance for debonding of the tissue paper that can potentially lead todecreases in tensile strength.
When applied to tissue paper, the lotion cv,..l..,~;l;u - ofthe present invention impart a soft, lubricious, lotion like feel to the user of the paper.
30 This particular feel has also been .I.~ ,i as "silky", "slick", "smooth", etc. Such a lubricious, lotion-like feel is particularly beneficial for those having more sensitive skin due to chronic conditions such as skin dryness or I,.,.~u~ uid~, or due to more transient conditions such as colds or allergies.

WO 95/16824 ~ 2 1 7 7 0 3 8 PCTNS94113674 1. Emolliellt The key active ingredient in these lotion ,u~ JuaiLiOI~5 is one or more emollients. As used herein, an emollient is a material that softens, soothes, supples, coats, lubricates, moisturizes, or cleanses the skin. An emollient 5 typically ~ u ~ several of these objectives such as soothing, ~I~uia~u~ , and lubricating the skin. For the purposes of the present invention, these emollients havl~ either a plastic or fluid consistency at 2ûC,i.e., at ambient L~ ,laLul~a. ~his particular emollient l,u~ ;aL~Il~ allows the lotion ~ u to impart a soft, lubricious, lotion-like feel.
The emollients useful in the present invention are also substantially free of water. By "~u~LallLi.. ly fre~ of water" is meant that water is not "y added to the emollient. Addition of water to the emollient is not necessary in preparing or using the lotion ~c mrrlcitif~n~ of the present invention and could require an additional drying step However, minor or trace quantities of water in the emollient that are picked as a result of, for example, ambient humidity can be tolerated without adverse effect. Typically, the emollients used in the present invention contain about 3% or less water, preferably about 1% or less water, most preferably about 0.5% or less water.
Emollients useful in the present invention can be petroleum-based, fatty acid ester type, alkyl etho~ ylate type, or mixtures of these emollients.
Suitable petroleum-based emollients include those h~Jlu~ ulla, or mixtures of ~yd~u~ ù~ having chain lengths offrom 16 to 32 carbon atoms.
Petroleum based llyJIu~ ulla having these chain lengths include mineral oil (also known as "liquid petrolatum") and petrolatum (also known as "mineral wax," "petroleum jelly" and "mineral jelly"). Mineral oil usually refers to lessviscous mixtures of 1~ ,d. u~ ol~S having from 16 to 20 carbon atoms.
Petrolatum usually refers to more viscous mixtures of l~ O-,albulla having from 16 to 32 carbon atoms. Petrolatum is a particularly preferred emollient for lotion ~ of the present invention.
Suitable fatty acid ester type emollients include those derived from C12-C2g fatty acids, preferably C16-C22 saturated fatty acids, and short chain (Cl-Cg, preferably Cl-C3) monohydric alcohols. Representative examples of such esters include methyl palmitate, methyl stearate, isopropyl laurate, isopropyl myristate, isopropyl palmitate, and ethylhexyl palmitate. Suitable fatty acid ester emollients can also be derived from esters of longer chain fatty alcohols (C12-C2g, preferably C12-Cl6) and shorter chain fatty acids e.g., lactic acid, such as lauryl lactate and cetyl lactate.
~.

W095116824 2 1 77 03~ PCT/US94~13674 --Suitable alkyl ethoxylate type emollients include Cl2-CI8 fatty alcohol ethoxylates having an average of from 3 to 30 oxyethylene units, preferably from about 4 to about 23. Representative examples of such alkyl ethoxylates include laureth-3 (a lauryl ethoxylate having an average of 3 oxyethylene 5 units), laureth-23 (a lauryl ethoxylate having an average of 23 oxyethylene units), ceteth-10 (a cetyl ethoxylate having an average of 10 u~ l..,c units) and steareth-10 (a stearyl ethoxylate having an average of 10 oxyethylene units). These alkyl ethoxylate emollients are typically used in with the petroleum-based emollients, such as petrolatum, at a 10 weight ratio of alkyl ethoxylate emollient to petroleum-based emollient of from about 1:1 to about 1:3, preferably from about 1:1.5 to about 1:2.5.
Besides petroleum-based emollients, fatty acid ester emollients and alkyl ethoxylate emollients, the emollients useful in the present invention can include minor amounts (e.g., up to about 10% of the total emollient) of other, 15 .o.~ic,,~;ull~l emollients. These other, ..u..i...~iu..~l emollients include propylene glycol, glycerine, triethylene glycol, spermaceti or other waxes, fatty acids, fatty alcohols and fatty alcohol ethers having from 12 to 28 carbonatoms in their fatty chain, such as stearic acid, cetyl alcohol, ~,. u~.u~' ~ J
fatty alcohols; glycerides, ac~t..~51.r.,~;.;l~, and ethoxylated glycerides of C12-20 C28 fatty acids; other fatty esters of PGI.r ~ u~r alcohols; lanolin and itsderivatives; and pOl)~a;lu~ having a viscosity at 20C of from about 5 to about 2,000 centistokes such as disclosed in U.S. patent 5,059,282 (Ampulski et al), issued October 22, 1991, which is il,cul~.ù~ d by reference. These other emollients should be included in a manner such that the solid or 25 semisolid '~ of the lotion ~ are maintained.
The amount of emollient that can be included in the lotion ~
will depend on a variety of factors, including the particular emollient involved, the lotion-like benef ts desired, the other .. 1 ,., ~ in the lotion ~ u...l.v~;l;., ~ and like factors. The lotion ~ , can comprise from about 20 to about 95% ofthe emollient. Preferably, the lotion ~.(. 1.. ~;l;
comprises from about 40 to about 80%, most preferably from about 50 to about 75%, ofthe emollient.
2. r ~ _~ ' 3 A~ent An especially key component of the lotion ~ .. of the present invention is an agent capable of ;., ~b:l~ the emollient on the surface of the paper to which the lotion ~,,...1...~;l;l. is applied. Because the emollient in WO g5/16824 2 1 7 7 PCT/lJS94/1367 ~ ' the ~ .,. has a plastic or fluid consistency at 20C, it tends to flow or migrate, even when subjected ~:o modest shear. When applied to a tissue paper web, especially in a melted or molten state, the emollient will not remainprimarily on the surface of the paper. Instead, the emollient will tend to 5 migrate and flow into the interior of the paper web.
This migration of the emollient into the interior of the web can cause undesired debonding of the paper by interfering with the normal hydrogen bonding that takes place between the paper fibers. This usually leads to a decrease in tensile strength of the paper. It also means much more emollient 10 has to be applied to the paper ~veb to get the desired lubricious, lotion-like feel benefits. Increasing the level of emollient not only increases the cost, but also UA~ fl.)~ the debonding problem of the paper .
The l " _ agent counteracts this tendency of the emollient to migrate or flow by keeping the emollient primarily localized on the surface of 15 the tissue paper web to which the lotion ~ u, ~ is applied. This is believed to be due to the fact that the i ' ' " agent forms hydrogen bonds with the tissue paper web. Through this hydrogen bonding, the ' " ,, agent becomes lo~alized on the surface of the paper. Since the ' " ,, agent is also miscible with the emollient ( or solubilized in the 20 emollient ~vith the aid of an appropriate emulsifier), it entraps the emollient on the surface of the paper as well In addition to being miscjble with (or solubilized in) the emollient, the ." agent needs to have a melting point of at least about 40C. This is so the; vl~ agent itself will not have a tendency to migrate or flow.
25 Preferred ' " _ agents ~vill have melting points of at least about 50C.
Typically, the ' ' 3 agent will have a melting point in the range of from about 50 to about 150C.
Suitable; . .1. ';, ;. .~ agents for the present invention can comprise pûlyl.~JluA~ fatty acid esters, p~lrh~dluAy fatty acid amides, and mixtures 30 thereo To be useful as; ""-~ agents, the PUIYI~ IUA~ moiety ofthe ester or amide has to have at least two flree hydroxy groups. It is believed that these free hydroxy groups are the ones that co-crosslink through hydrogen bonds with the cellulosic fibers of the tissue paper web to which the lotion c.,...l...~:l;..l. is applied and homo-crosslink, also through hydrogen bonds, the 35 hydroxy groups of the ester or amide, thus entrapping and 2'"' ' g the other , in the lotion matrix. Preferred esters and amides will have three or more free hydroxy grollps on the ~UI,~ d~ UA,y moiety and are ~.
_ _ _ . .

2 1 770~8 16 typically nonionic in character. Because of the skin sensitivity of those using paper products to which the lotion ~ ,o~ ". is applied, these esters and amides should also be relatively mild and non-irritating to the skin.
Suitable pol~ i, u,~y fatty acid esters for use in the present invention 5 will have the formula:
1l R--C--O Y
- - n 10 wherein R is a Cs-C3 1 l~yJI uc~ group, preferably straight chain C7-C I g alkyl or alkenyl, more preferably straight chain Cg-C 1 7 alicyl or alkenyl, most preferably straight chain C 11 -C 17 alkyl or alkenyl, or mixture thereof; Y is a polyh~J,u~ i,u.,G,i,~l moiety having a h~J.u.,~ l chain with at least 2 free hydroxyls directly connected to the chain; and n is at least 1. Suitable Y
groups can be derived from polyols such as glycerol, p.,~.. ~lluiLul~ sugars such as raft`inose, ' ' u~c, galactose, sucrose, glucose, xylose, fructose, maltose, lactose, mannose and erythrose; sugar aicohols such as erythritol, xylitol, malitol, mannitol and sorbitol; and anhydrides of sugar aicohols such as sorbitan.
One class of suitable ~.c,l~h~i.u,.~ fatty acid esters for use in the present invention comprises certain sorbitan esters, preferably the sorbitan esters of C 1 6-C22 saturated fatty acids. Because of the manner in which they are typicaily ~ ..ur~.Lul cd, these sorbitan esters usually comprise mixtures ofmono-, di-, tri-, etc. esters. R~ c~c~ Li ;c examples of suitable sorbitan 25 esters include sorbitan palmitates (e.g., SPAN 40), sorbitan stearates (e.g.,SPAN 60), and sorbitan behenates, that comprise one or more of the mono-, di- and tri-ester versions of these sorbitan esters, e.g., sorbitan mono-, di- and tri-palmitate, sorbitan mono-, di- and tri-stearate, sorbitan mono-, di and tri-behenate, as well as mixed tallow fatty acid sorbitan mono-, di- and tri-esters.30 Mixtures of different sorbitan esters can also be used, such as sorbitan palmitates with sorbitan stearates. Particularly preferred sorbitan esters are the sorbitan stearates, typically as a mixture of mono-, di- and tri-esters (plus some tetraester) such as SPAN 60, and sorbitan stearates sold under the trade WO 95116824 2 ~ 7 7 ~ 3 8~ . ~ . PCIIIJS94/13674 name GLYCOMUL-S by Lonza. Inc. Aithough these sorbitan esters typically contain mixtures of mono-, di- and tri-esters, plus some tetraester, the mono-and di-esters are usually the l~lt iO~ L species in these mixtures.
Another class of suitabl~ polyl.~ll u,.y &tty acid esters for use in the 5 present invention comprises certain glyceryl monoesters, preferably glyceryl monoesters of C 1 6-C22 saturated fatty acids such as glyceryl ~u~oste~l a~e, glyceryl ~ tJ~ e, and gl~/ceryl " ~ h ~ -:e Again, like the sorbitan esters, glyceryl monoester mixtlJres will typically contain some di- and triester.
However, such mixtures should contain IJledullu.l~lllLly the glyceryl monoester 10 species to be useful in the present invention.
Another class of suitabll~ polyhydroxy fatty acid esters for use in the present invention comprise certain sucrose fatty acid esters, preferably the C12-C22 saturated fatty acid e~ters of sucrose. Sucrose - ~ are particularly preferred and include sucrose - aLe and sucrose - ale.
Suitable pol~ . UAy fa~ty acid amides for use in the present invention will have the formula:
o R1 wherein Rl is H, Cl-C4 hydrocarbyl, 2-1ly-11uA~ llyl, 2 h~J~UAYU~Ut~
II~.,.IlUA~ I,rl, I...,.llUAylJlUIlyl or a mixture thereof. preferably Cl-C4 aikyl, ...~ll,UA~.,lh~l or Ill.,.llUAy~lU~l, more preferably Cl or C2 alkyl or Ill~,.lIUA,~ , most preferably Cl alkyl (i.e., methyl) or lll~,~llUA~ylu~ and R2 js a Cs-C3 I hydrocarbyl group, preferably straight chain C7-C 19 aikyl or alkenyl, more preferably straight chain Cg-C 1~ alkyl or alkenyl, most preferably straight chain C 11 -C 17 alkyl or alkenyl, or mixture thereof; and Zis a p~l~tl~luAyll.rilu~ yl moiety having a linear hr~i~u~b~ chain with at 3û least 3 hydroxyls directly connected to the chain. See U.S. patent 5,174, 927 (Honsa), issued December 29, ] 992 (herein il~,Ol ~JOlaLt~ by reference) which discloses these polyhydroxy fat~.y acid amides, as well as their preparation.
The Z moiety preferably will be derived from a reducing sugar in a reductive amination reaction; most preferably glycityl. Suitable reducing sugars mclude glucose, fructose, maltose, lactose, galactose, mannose, and . . .. .. ...... .. . ... .... . .. . . ... . ... . .. . . . . . .... . . ...

xylose. High dextrose corn syrup, high fructose corn syrup, and high maltose corn syrup can be utilized, as well as the individual sugars listed above. Thesecorn syrups can yield mixtures of sugar .:.~ ,1,. ,.,...1~ for the Z moiety.
The Z moiety preferably will be selected from the group consisting of-CH2-(CHOH)n-CH20H,-CH(CH20H)-[(CHOH)n I]-CH20H,-CH20H-CH2-(CHoH)2(CHoR3)(CHoH)-CH2oH~ where n is an integer from 3 to 5, and R3 is H or a cyclic or aliphatic ' '- Most preferred are the glycityls where n is 4, particularly -CH2-(CHOH)4-CH20H.
In the above formula, Rl can be, for example, N-methyl, N-ethyl, N-10 propyl, N-isopropyl, N-butyl, N-2-I~ UA~ YI~ "llo~yy.uyy~ orN-2-hydroxypropyl,. R2 can be selected to provide, for example, cocamides, , oleamides, lauramides, ~"r.;alGI~l;J~ ,Gyl;~ f~c5~
, i 11 ..GIIl;lCs, etc. The Z moiety can be l-d~,u~.y~;lu~,;Lyl, 2-dcu~.yrlu~ yl, I-dcu~y ' yl, I-deoxylactityl, I-dcuAy~;GlG~,l;lyl, 1-.I~,~,~II.. ~yl, I-dc~l~.. ,Gllu~l;uL;Lyl, etc.
The most preferred polyhydroxy fatty acid amides have the general formula:

whereinRIismethylor ll~ luAyyluyjl, R2isaCIl-Cl7straight-chainalkyl or alkenyl group. These include N-lauryl-N-methyl glucamide, N-lauryl-N-u~.~ylu~Jyl glucamide, N-cocoyl-N-methyl glucamide, N-cocoyl-N-lll.,lllu~yyluyjl glucamide, N-palmityl-N--.,.,LIIuAyy.uy,l glucamide, N-25 tsllowyl-N-methyl glucamide, or N-tallowyl-N~ .I.u,.yy.uyyl glucamide.
As previously noted, some of the ~ ' "' ' 3 agents require an emulsifier for ' ' " in the emollient. This is particularly the case for certain ofthe glucamides such as the N-alkyl-N-...~Il.u,.yy.uy~l glucamides having HLB values of at least about 7. Suitable emulsifiers will typically 30 include those having HLB values below about 7. In this regard, the sorbitan esters previously described, such as the sorbitan stearates, having HLB values of about 4.9 or less have been found useful in solubilizing these glucamide ;..- -- ,1,:1, :.~ agents in petrolatum. Other suitable emulsifiers include steareth-2 (pol~"Lh~k,.,~, glycol ethers of stearyl alcohol that conform to the formula WO 95/16824 2 1 ~ 7 0 3 8 PCIIUS94/13674 , , CH3(CH2)17(OCH2CH2)nOI~. where n has an average value of 2), sorbitan tristearate, isosorbide laurate, and glyceryl IllUllOs~ . The emulsifier can be included in an amount suffcient to solubilize the i~ ...l, ': ;"~. agent in the emollient such that a substantially l-,.",..g. I f O"` mixture is obtained. For 5 example, an ~,U~IU~illlGL~,Iy 1 1 mixture of N-cocoyl-N-methyl glucamide and petrolatum that will normally not melt into a single phase mixture, will melt jnto a single phase mixture upon the addition of 20% of a 1:1 mixture of steareth-2 and sorbitan tristearate as the emulsifier.
The amount of .. 1 ''' ~ agent that should be included in the lotion 10 ~.. .,, ~1 .v.:: ;., will depend on a ~ariety of factûrs, including the particular emollient involved, the particular ;.,. ~ .l '~; ;,~e agent involved, whether anemulsifier is required to solubilize the; ..,.~ ;.." agent in the emollient, theother ~.u~ in the the lofion ~u~ and like factors. The lotion ;u,l can comprise from about 5 to about 80% ofthe . ' " g 15 agent. Preferably, the lotion r~ u~ comprises from about 5 to about 50%, most preferably from about 10 to about 40%, ofthe i -' ' g agent.
3. Optional! E~ydrophilic Surf~rt~nt In many instances, lotion ~ u .l.. .~ according to the present 20 invention will be applied to tissue paper webs that will be used as toilet tissue.
In such cases, it is highly desirable that the paper web treated with the lotion ~u~ v~ be sufficiently wettable. Depending upon the particular ' ' ' _ agent used in the lotion ~ . of the present invention, an additional hydrophilic surfactant (or a mixture of hydrophilic surfactants) may,25 or may not, be required to improve wettability. For example, some ' "' ' ,, agents, such as N cocoyl-N-.l,~.llu~JluL~f~ glucamide have HLB values of at least about 7 and are sufficiently wettable without the addition of hydrophilic surfactant. Other ' ' ~ agents such the sorbitan stearates having HLB ~Jalues below about 7 will require addition of 30 hydrophilic surfactant to improve wettability if the lotion ~.u ~ is applied to paper webs used as toilet tissue.
Suitable hydrophilic surfactants will be miscible with the emollient and the ;- - . -- l ;~ agent so as to form 1 ~. - ..~g. ~f U' 1~ mixtures. Because of the skin sensitivity of those using paper products to which the lotion ~
35 is applied, these surfactants should also be relatively mild and non-irritating to the skin. Typically, these hydraphilic surfactants are nonionic to be not only non-irritating to the skin, but aiso avoid other undesirable effects on the tissue paper, e.g., reductions in tensile strength.
Suitable nonionic surfactants will be ~ub~LAA~liAAlly l~ ..Y after the lotion ....,..l,,J~;l;Ci~ is applied to the tissue paper web and will typically 5 have HLB values in the range of from about 8 to about 23. To be ~lU...,.;5.AA~v,y, these nonionic surfactants will typically have melt lelll,~ dLUli,~
greater than the t~ ,,alul~ commonly clll,u~ elcii during storage, shipping, .~.~,.,,I.~..,i;~;..g, and use oftissue paper products, e.g., at least about 30C In this regard, these nonionic surfactants will preferably have melting 10 points similar to those of the ~ A agents previously described.
Suitable nonionic surfactants for use in lotion ~.... ,.l.~ ,~;l;.. ~ of the present invention include alkylglycosides; ~ ,vs;d,. ethers as described in U.S. patent 4,011,389 (Langdon, et al), issued March 8, 197~;
alkylpolyethoxylated esters such as Pegosperse 1000MS (available from 15 Lonza, Inc., Fair Lawn, New Jersey), ethoxylated sorbitan mono-, di- andlor tri-esters of C 1 2-C 18 fatty acids having an average degree of CLllUA~ iV,I offrom about 2 to about 2û, preferably from about 2 to about 10, such as TWEEN 60 (sorbitan esters of stearic acid having a average degree of e~llvA~ ivll of about 20) and TWEEN 61 (sorbitan esters of stearic acid 20 having an average degree of ethoAylation of about 4), and the ~c~
products of aliphatic alcohols with from about I to about 54 moles of ethylene oxide. The aikyl chain of the aliphatic alcohol is typically in a straisht chain(linear) c. lllilvl..Al;",l and contains from about 8 to about 22 carbon atoms.
Particularly preferred are the ~v~ V' ' products of alcohols having an 25 alkyl group containing from about 11 to about 18 carbon atoms with from about 3 to about 30 moles of ethylene oxide per mole of alcohol. Examples of such ethoxylated aicohols include the c. ,. 1...~Al ;.... products of myristyl alcohol with 7 moles of ethylene oxide per mole of alcohol, the ~.. 1 . - -~ ;.
products of coconut alcohol (a mixture of fatty alcohols having alkyl chains varying in length from 10 to 14 carbon atoms) with about 6 moles of ethylene oxide. A number of suitable ethoxylated alcohols are ,~v.. ~ , available, including TERGlTOL 1 5-S-9 (the ~.v ~ ;.... product of C I l-C ls linear alcohols with 9 moles of ethylene oxide), marketed by Union Carbide Corporation; KYRO EOB (~ ;., product of C 1 3-C I s linear alcohols with 9 moles of ethylene oAide), marketed by The Procter & Gamble Co., the NEODOL brand name surfactants marketed by Shell Chemicai Co., in particular NEODOL 25-12 (. ,). .~ product of C 12-C I s linear alcohols ... ..

product of C12-Cl3 linear alcohols with 6.5 moles of ethylene oxide that has been distilled (topped) to remo~e certain impurities), and especially the PLURAFAC brand name surfactants marketed by BASF Corp., in particular 5 PLURAFAC A-38 (a ,~ 1;., product of a Clg straight chain alcohol with 27 moles of ethylene oxide). (Certain of the hydrophilic surfactants, in particular ethoxylated alcohols such as NEODOL 25-12, can also function as alkyl ethoxylate emollients).
The amount of hydrophilic surfactant required to inerease the 10 wettability of the lotion comrnciricln to a desired level will depend upon the HLB value and level of ~ ' 3 agent used, the HLB value of the surfactant used and like factors. The lotion c-.,..l o~:l;.... can comprise fromabout 2 to about 50% of the hydrophilic surfactant when needed to increase the wettability properties of the u~ o~ nl~ Preferably, the lotion 15 '.~ J`;I;'~" comprises from about 2 to about 20%, most preferably from about 5 to about 15%, of the hydrophilic surfactant when needed to increase wettability 4. Other Oprinn~l Components Lotion ~.,,.. I.~ .c l ;.~ can comprise other optional ~ typically present in emollient. creams, and lotions ofthis type. These optional n....~1~ include perfumes, disinfectant ~ il,4.,~Cli41 actives, ~ 41~ll4~C~IL;~,41 actives, film formers, deodorants, opacifiers, astringents, solvents and the like. In addition, stabilizers can be added to enhance the shelf 25 life of the lotion ~,ul 1.~ I ;ol~ such as cellulose derivatives, proteins and lecithin. All of these materials are well known in the art as additives for suchrul~ l4iiu,~ and can be employed in appropriate amounts in the lotion J~ ofthe present invention.
C. Treating Tissue p~,,n~r With Lotion ComDssition In preparing lotioned paper products according to the present invention, the lotion cc~ nli is applied to at least one surface of a tissue - paper web. Any of a variety of application methods that evenly distribute lubricious materials having a molten or liquid consistency ean be used.
Suitable methods include spraying, printing (e.g., n~,Au~;l4~Lc printing), eoating (e.g., gravure eoating), extrusion, or ' ofthese application techniques. e.g. spraying the lotion ~u.l.l..~;l;n~ on a rotating surface, sueh as a calender roll, that then transfers the ..i, I.u~; I ;n~- to the surface of the paper web. The lotion cu~ Jua;lh~l~ can be applied either to one surface of the tissuepaper web, or both surfaces. Preferably, the lotion cu~ n~:l;oll is applied to both surfaces of the paper web.
The manner of applying the lotion c~ .n~;l ;nll to the tissue paper web should be such that the web does not become saturated with the lotion f~"l.l..~;l;.~.. If the web becomes saturated with the lotion ~ .u~;l;.,." thereis a greater potential for debonding of the paper to occur, thus leading to a decrease in the tensile strength of the paper. Also, saturation of the paper web10 is not required to obtain the softness and lotion-like feel benefits from thelotion ~...,..I,.~;l;r,ll ofthe present invention. Particularly suitable application methods will apply the lotion ~ ;l;n~l primarily to the surface, or surfaces of the paper web.
The lotion ~ u~ o~;l;oll can be applied to the tissue paper web after the 15 web has been dried. i.e. a "dry web" addition method. The lotion . ~.,,.1...~;l;....
is applied in an amount of from about 2 to about 20% by weight of the tissue paper web. Preferably, the lotion cu..~ ;u~ is applied in an amount of from about 5 to about 15% by weight of the tissue paper web, most preferably from about 5 to about 10% by weight of the web. Such relatively low levels of 20 lotion ~ are adequate to impart the desired softness and lotion-like feel benefits to the tissue paper, yet do not saturate the tissue paper web to such an extent that absorbency, wettability and particularly, strength, are substantially affected.
The lotion ~,u,-",o~;L;on can also be applied .~.. . r"" l~ to the 25 surface(s) of the tissue paper web. By "r~on~ I "` ",1l is meant that the amount, pattern of distribution, etc. of the lotion rnmroCitin~ can vary over the surface of the paper. For example, some portions of the surface of the tissue paper web can have greater or lesser amounts of lotion ..... I.n~;l ;r.. ~, including portions ofthe surface that do not have any lotion ~.. 1.. ~:l;... on it.
The lotion ~u .l.. ,~ . can be applied to the tissue paper web at any point after it has been dried. For example, the lotion l,~...\l~n~;l;nl~ can be applied to the tissue paper web after it has been creped from a Yankee dryer, but prior to calendering, i.e., before being passed through calender rolls. The lotion ~u .~ ;., can also be applied to the paper web after it has passed 35 through such calender rolls and prior to being wound up on a parent roll.
Usually, it is preferred to apply the lotion ~u..~l~u~;l;u to the tissue paper as it wo 95116824 ~ 0 3 8 PC'r,~US94/13674 is being unwound from a parent roil and prior to being wound up on sma.ler, finished paper product rolls.
The lotion c ~ .c,~ is typically applied from a melt thereof to the tissue paper web. Since the lotion ~ ,o~;l;c-~ melts at S~ ;r.~ y above S ambient ~tl~ dlUI~,~, it is usually applied as a heated coating to the tissue paper web. Typically, the lotion ~.~J'"~ li is heated to a ~ .,.dLUI~: in the range from about 35 to about 1.00C, preferably from 40 to about 90C, prior to being applied to the tissue paper web. Once the melted lotion .. has been applied to the tissue paper web, it is allowed to cool and 10 solidify to form solidified coating or film on the surface of the paper.
In applying lotion ~ of the present invention to tissue paper webs, gravure coating and extrusion coating methods are preferred. Figure I
illustrates one such preferred me~thod involving gravure coating. Refe.-ring to Figure 1, a dried tissue web I is unwound from parent tissue roll 2 (rotating in15 the direction indicated by arrow 2a) and advanced around turning roll 4.
From turning roll 4, web I is ad~anced to gravure coating station 6 where the lotion ~ u .l..~ ,l. is then applied to both sides of the web. A~er leaving station 6, web I becomes a lotioned web indicated by 3. Lotioned web 3 is then advanced around turning roll 8 and then wound up on lotioned tissue 20 parent roll 10 (rotating in the direction indicated by arrow 10a).
Station 6 comprises a pair of linked offset gravure presses 12 and 14.
Press 12 consists of a lower gra~/ure cylinder 16 and an upper offset cylinder 18; press 14 similarly consists of a lower gravure cylinder 20 and an upper offset cylinder 22. Gravure cylinders 16 and 20 each have a chrome plated 25 surface, while offset cylinders 1~ and 22 each have a pc,l~-cll.~ e rubber surface. These gravure and offsl~t cylinders rotate in the directions indicated by arrows 16a, 18a, 20a and 22a, respectively. As shown in Figure 1, offset cylinders 18 and 22 are opposed to one another and provide a nip area indicated by 23 through which web I passes.
Positioned beneath gravure cylinders 16 and 20 are fountain trays 24 and 26, respectively. Hot, molten (e.g., 65C) lotion çu"~l,û~ is pumped into each of these heated trays 2~ and 26 to provide reservoirs of the molten lotion comr~lcition as indicated arrows by 30 and 32" c "~ . As gravure cylinders 16 and 20 rota~e in the directions indicated by arrows 16a and 20a within reservoirs 30 and 32, they pick up a quantity of molten lotion "" E~ccess lotion on each of the gravure cylinders 16 and 20 is then removed by doctor blades 34 and 36, respectively.

The lotion composition remaining on gravure cylinders 16 and 20 is then transferred to heated offset cylinders 18 and 22 (rotating in the opposite direction as indicated by arrows 1 8a and 22b) in nip areas 38 and 40 between the respective pairs of cyiinders. The lotion f .. 1 ~u~ transferred to offset 5 cylinders 18 and 22 is then transferred to the opposite sides of web I . The amount of lotion ....~ ;u transferred to web I can be controlled by: ( I ) adjusting the width of nip area 23 between offset cylinders 18 and 22; and/or (2) adjusting the width of nip areas 38 and 40 between ~,~vu.c/uai~;t cylinder pairs 16118 and 20/22.
Figure 2 illustrates an alternative preferred method involving slot extrusion coating. Referring to Figure 2, a dried tissue web 101 is unwound from parent tissue roll 102 (rotating in the direction indicated by arrow 102a) and then advanced around turning roll 104. From turning roll 104, web 101 is advanced to slot extrusion coating station 106 where the lotion ~.U...I..J~ J isthen applied to both sides ofthe web. After leaving station 106, web 101 becomes a lotioned web indicated by 103. Lotioned web 103 is then wound up on lotioned tissue parent roll 110 (rotating in the direction indicated by arrûw IlOa).
Station 106 comprises a pair of spaced slot extruders 112 and 114.
Extruder 112 has an elongated slot 116 and a web contacting surface 11 8;
extruder 114 similarly has an elongated slot 120 and a web contacting surface 122. As shown in Figure 2, extruders 112 and 114 are oriented such that surface 118 is in contact with one side of web 101, while surface 122 is in contact with the other side of web 101. Hot, molten (e.g., 65C) lotion . . - is pumped to each of extruders 112 and 114 and is then extruded through slots 116 and 120, respectively.
As web 101 passes over the heated surface 118 of extruder 112 and reaches slot 116, the molten lotion .~ extruded from slot 116 is applied to the side of web 101 in contact with surface 118. Similarly, as web 101 passes over heated surface 122 of extruder 114 and reaches slot 120, the molten lotion c~ ;l;.... extruded from slot 120 is applied to the side of web 101 in contact with surface 122. The amount of lotion ~.u.,,l,,~c:.;"..
transferred to web 101 is controlled by: (1) the rate at which the molten lotion .,~ ,.. is extruded from slots 116 and 122; and/or (2) the speed at which web 101 travels while in contact with surfaces 118 and 122.
