FIELD OF THE INVENTION
This invention relates to an aerosol hair spray f ormulation containing 0 . 5 to 15 weight percent of a water--dispersible or water--dissipatible, linear sulfopolyester having a Tg of 40C to 50CC and an inherent viscosity of 0 . 24 to 0 . 60 dl~g which contains repeat units from 20 to 26 mole percent dimethyl--5--sodiosulfoisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboYylic acid; 10 to 30 mole percent 1,4--cycl--hf~Y;~n~Ai- ' h;ln-l and 70 to 90 mole percent diethylene glycol, based on 100 mole percent diol; and up to 60 weight percent of an alcohol. The aerosol hair spray formulations are clear, have; uvt:d dry time and curl retention, and eYhibit less than 20 NTU' s, which is a measure of turbidity, even at high concentrations of 2 0 alcohol .
BACKGROUND OF THE INVENTION
Hair sprays provide human hair with a particular shape or configuration and function by applying a thin film of a resin or gum onto the hair to adhere adjacent hairs together so that they retain the particular shape or configuration at the time of application.
U. S . Pat . No . 5 ,164 ,177 discloses a hair spray formulation containing 2--40% of a linear polymer 3 0 including at least one vinyl or acrylate monomer, a water--soluble electrolyte, 30--90% water, and 0 30%
alcohol. The water--soluble electrolyte is added to lower the viscosity of the composition to achieve a higher percentage of polymer in the composition. Such formulations, however, have poor humidity resistance, hold and curl retention.
_ _ _ _ _ _ _ _ . _ .... . . . . _ . _ ... _ ~0 95/3343~ ~ 1 9 ~ 7 4 ~ ` 6~69 , U.S. Pat. No. 4,a~1,580 discloses hair spray formulations containing a water--dispersible or water--dissipatible linear sulfo--polyester f ixative in a water~alcohol mixture. The diol component of the sulfopolyester contains at least 20 mole percent poly(ethylene glycol). Such formulations are fast drying and have good hair holding properties but possess the disadvantage of being very difficult to remove from the hair. For example, prolonged washing is re,rluired to completely remove the water--dispersible, linear polyester f ixative to obtain hair with no tacky or sticky feel. U. S . Pat. No. 4, 300, 580 suggests adding other substances such as poly (alkylene ether) to increase the hardness and reduce the t~rk;nPsS of the formulations. However, when such formulations containing a combination of the poly(alkylene glycol) and sulfopolyester are applied to hair and allowed to dry, the f iYative causes a matting of the hair . Such matting hinders combing, brushing and styling of hair.
U.S. Pat. No. 5,266,303 discloses hair spray formulations containing a water--dispersible sulfopolyester having a glass transition temperature of 36C to 40C, a water--soluble polyvinyl lactam polymer, and water . The perf ormance characteristics of such formulations are good. However, the drying time is too long, and the addition of alcohol, which would improve - dry time, causes the formulations to become cloudy.
Thus, the use of alcohol is not an option f or improving the dry time of such f ormulations .
U.S. Pat. No. 5,158,762, discloses hair spray compositions containing a blend of a sulfopolyester and a water--soluble polymer in water. The sulfopolyester contains at least 4 0 mole percent 1,4--cyclnhPY~nP~i t~-anol. The performance characteristics of such formulations are good, however, _ _ _ wo g~l33437 21~ 0 7 ~ 6 r~ s?~g ~ -- 3 --the drying time is too long, and the addition of alcohol, which would improve dry time, causes the formulations to become cloudy. Thus, the use of alcohol is not an option for improving the dry time of such 5 formulations.
U.S. Pat. No. 5,266,308, discloses aqueous hair spray compositions which contain a sulfopolyester, a water--soluole polymeric resin and a homopolymer of polyvinylpyrrolidone . The perf ormance characteristics 10 of such formulations are good, however, the drying time is too long, and the addition of alcohol, which would improve dry time, causes the f ormulations to become cloudy. Thus, the use of alcohol is not an option for improving the dry time of such formulations.
In contrast, the present inventors have unexpectedly detPrm;n~cl that aerosol hair spray formulations which are clear and provide properties considered desirable for hair preparation such as fine spray patterns, fast drying times, prolonged curl 2 0 retention under humid conditions, good holding power and resistance to build--up may be prepared with as much as 60 weight percent alcohol to facilitate rapid drying on the hair . The hair spray f ormulations of the present invention are clear and exhibit less than 20 NTU' 5 which is a measure of turbidity. In the cosmetic field greater than 20 NTU' s is characteristic of a cloudy mixture that is visible to the eye.
SUMNARY OF THE INVENTION
Accordingly, it is one object of the present invention to provide a clear aerosol hair spray f ormulation .
It is another object of the invention to provide a aerosol hair spray f ormulation which i5 not tacky, has a fast drying rate, acceptable body, consistency and Wo 95/33437 21 9 0 7 ~ u PCTrUS95/06269 .~
exhibits improved curl ~t~bn~ion.
Another obj ect of e invention is to provide a aerosol hair spray formulation which i8 clear and has PY(`Pl 1 Pnt storage stability and which does not clog the S exit port o~ a aerosol container.
These and other objects are accomplished herein by an aerosol hair spray formulation having improved dry time and curl retention and exhibiting les6 than 20 NTU' s as a measure of clarity which comprises:
(1) a sulfopolyester having a Tg of 40C to 50C
and an inherent viscosity of 0. 24 to 0 . 60 dl~g which consists essentially of repeat units from (a) a dicarboxylic acid component comprising of 20 to 26 mole percent dimethyl--5--soA; osl1l foisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboxylic acid;
(b) a diol L-l L compri5ing of 10 to 30 mole percent l,4-cycl~hPYAn~o~;r thanol and 70 to 90 mole percent diethylene glycol, based on 100 mole percent diol;
(2) a water~alcohol li~auid vehicle; and ( 3 ) 3 to 60 weight percent based on the weight of -nts (1), (2), and (3) of a propellant selected from the group consisting of a Cl-- C4 aliphatic hydrocarbon , dimethyl ether , and mixtures thereof, provided the sulfopolyester, component (1), is present 30 in an amount of 0.5 to 15 weight percent, based on the total weight of the aerosol hair spray formulation.
DESCRIPTION OF THE INVENTION
The aerosol hair sprays of the present invention 35 exhibit less than 20 NTU' s which is a measure of the ~O9~l33437 21~0 7~ G ~ C.. '71~9 .
., _ turbidity of a mixture . In the cosmetic f ield greater than 20 NTU' s is characteristic of a cloudy mixture that is visible to the eye. The clear aerosol hair spray formulations of this invention contain a sulfopolyester, 5 component tl), in an amount of 0.5 to 15 weight percent, preferably 3 to 10 weight percent, and more preferably 5 to 8 weight percent, based on the total weight of the aerosol hair spray formulation.
The sulfopolyester, c~ron-~nt (1), has a glass 10 transition t ~ , tu~ e of 40C to 50C and contains repeat units from a dicarboxylic acid, a diol and a difunctional sulf~ m~ . The dicarboxylic acid component of the sulfopolyester contains 20 to 26 mole percent of dimethyl--5--sodiosulfoisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboxylic acid. The diol component of the sulfopolyester contains 10 to 30 mole percent 1,4--cycl-~h~Y~np~l;; ?thanol and 70 to 90 mole percent diethylene glycol, based on 100 mole percent diol. The 20 sulfopolyester has an inherent viscosity (I.V.) of 0.24 to 0. 60 dl~g.
Component (2) of the aerosol hair spray is a liquid vehicle. The liquid vehicle may be water or a water~alcohol mixture. Distilled or deionized water are 25 the preferred sources of water since tap water generally contains ions which may precipitate the sulfopolyester, -nPnt (1). If a water~alcohol mixture is used, the amount of volatile organic components which include the alcohol and propellant cannot exceed 60% of the aerosol 30 hair spray formulation. Therefore, at least 40% of the formulation is water and the L. in;ng 60% is alcohol and propellant. Preferably a water~alcohol mixture is used wherein the alcohol is present in an amount of 20 to 30 weight percent based on the weight of the aerosol 35 hair spray formulation. The alcohol provides faster WO 95~33437 ~ l g 0 7 ~ 6 PCr/US95/06269 drying of the formula~ion on hair as compared to f ormulations prepared with only water as the liquid vehicle. The alcohol i5 an aliphatic straight or branched chain monohydric alcohol having 2 to 4 carbon 5 atoms. Isopropanol and ethanol are the preferred alcohols .
The aerosol hair spray f ormulations of the present invention require a propellant, componQnt t3). The propellant can be any liquefiable gas conventionally 10 used for ~erosol containers. Examples of materials that are suitable f or use as propellants are trichlorof luoromethane, dichlorodif luoromethane, dichlorotetraf luoroethane, monochloro~l l f l ~ romethane, trichlorotrifluoroethane, dimethyl ether, methane, 15 ethane, propane, n--butane and isobutane, used singly, or admixed. Water--soluble gases such as dimethyl ether, carbon dioxide, and~or nitrous oxide also can be used to obtain aerosols having reduced ~l i h~ 1 i ty .
Other insoluble, c esse~ gases such as nitrogen, 20 helium and fully--fluorinated oxetanes and Oyl'rAn~C also are useful to deliver the formulations from aerosol containers. Other means of delivery of the above--described aqueous styling aid formulations include, aerosol sprayers, all forms of bag--in--can 25 devices, in situ carbon dioxide (CO2) generator systems, ~ssors, and the like.
Preferably, the propellant is either a C1 -- C4 aliphatic hydrocarbon or dimethyl ether. A preferred aliphatic hydrocarbon propellant is a mixture containing 30 83 percent isobutane and 17 percent propane. The amount of the propellant is governed by normal f actors well known in the aerosol art. The level of propellant is generally from ~% to 60%, preferably from 5% to 45%, of the aerosol hair spray formulation. In the case where a 35 C1 -- C4 aliphatic hydrocarbon is used as the propellant, ....
~ W~9sl33437 2~ 9n7~ p~ 6269 generally 3 to 10 weight percent, preferably 4 to 7 weight percent, is employed. In the case where dimethyl ether is used as the propellant, generally, 20 to 40 weight percent, preferably, 30 to 35 weight percent, is 5 employed. If a propellant such as dimethyl ether utilizes a vapor pressure suppressant (e.g., trichloroethane or dichloromethane), for weight percentage calculations, the amount of suppressant is included as part of the propellant.
The aerosol hair spray formulations may optionally contain a water--soluble polymer or resin, ~ -n~nt (4)-The water--soluble polymer must be soluble or dispersible in liquid vehicle, component (2). The term "water--soluble" refers to any material that has solubility of at least 1 gram per 100 grams of water, i.e. 1%, preferably a solubility of at least 59~ by weight . Conversely, the term "water--insoluble" ref ers to substances that are insoluble at a level of less than 1 gram per 100 grams of water, i. e., less than 1% by weight. Solubility or dispersibility is det~r;n~d at ambient conditions (e.g., a temperature of 25C and atmospheric pL e~ ~UL ~) .
Water--soluble polymers useful in the formulations of the present invention are homopolymers or copolymers that can be rendered dispersible or 501uble in aqueous or water~alcohol mixtures. The water--soluble polymer is a synthetic, linear, homopolymer or random copolymer inr~ ;n~ at least one, and preferably two or more, vinyl or acrylate monomers of the following group:
Alkyl vinyl ethers 3 5 CH=CH2 Alkyl Acrylates 4 CH2=CH--C~R

Examples of preferred copolymers are the mono ethyl, isopropyl or n--butyl esters of poly (methyl vinyl ether~maleic acid);
poly(vinyl pyrrolidone~vinyl acetate, poly(vinyl pyrrolidone~ethyl methacrylate~methacrylic acid), 10 poly (ethyl acrylate~acrylic acid~N--t--butyl acrylamide), and poly (vinyl acetate~crotonic acid) .
Other suitable classes of polymers include anionic, nonionic, amphoteric and cationic polymers. Specific polymers include polyvinylpyrrolidone (PVP), copolymers 15 of PVP and methylmethacrylate, copolymers of PVP and vinyl acetate tVA), polyvinyl alcohol (PVA), copolymers of PVA and crotonic acid, copolymers of PVA and maleic anhydride, hyd~ ~sy~ yl cellulose, ~IydLo~y~L.~yl guar gum, sodium polystyrene sulfonate, 20 PVP~ethylmethacrylate~methacrylic acid terpolymer and octylacrylamide~acrylate~butylaminoethyl methacrylate copolymers, and mixtures . A pref erred vinyl polymer or copolymer contains at least 50 mole percent of the residues of n--vinyl lactam monomer such as 25 N--vinylpyrrol; rl i none .
With certain of the acidic water--soluole polymers, it may be nPcP~Ary to neutralize some acidic groups to promote 601ubility~dispersibility, e.g., PVA~crotonic acid. Neutralization and increased solubilization are 30 accomplished with one or more inorganic bases such as sodium hydroxide, potassium hydroxide, ammonium hydroxide and~or ammonium carbonate. Among stable organic bases are the water soluble bases such as monoethanolamine (MEA), diethanolamine (DEA), 35 triethanolamine (TEA), 2--methyl--2--amino--1--propanol .
WO 95/3343~ 2 1 9 ~ 7 4 ~ q (AMP), ;nn ~i~COlS, and the like, which help solubilize the polymer in water solutions. The level of neutralization required for solubilization varies for each polymer. All of the above--described acidic 5 polymers become soluble in water and hydroalcoholic solutions at 100% neutralization, and all described levels of water~alcohol~propellant solutions. The pH of these solutions usually ranges from 9 to 12. The lowest neutralization level needed to render the polymer water 10 soluble or dispersible depends on the kind of polymer, and the amount of alcohol, water and propellant. For instance, for poly(methyl vinyl ether~maleic acid) in water the lowest neutralization level is 40% with sodium hydroxide and AMP; for poly(ethyl acrylate~acrylic 15 acid/N--t--butyl acrylamide) the lowest neutralization level is 75% with AMP and 65% with sodium hydroxide. At these neutralization levels, the pH of the solutions range from 5 to 7. A slightly acidic or neutral pH such as this is preferred, however, the pH of the 20 formulations of the present invention can vary from 4 to 9 . Saponif ication of the ester linkages may occur under a 1 kA l; nF~ conditions .
The water--601uble polymers may be prepared according to known procedures wherein, for example, a 25 N--vinyl lactam is polymerized, optionally in the presence of one or more other vinyl monomers such as those described above. The N--vinylpyrrolidinone~vinyl acetate copolymers supplied by BASF under the trademark LWISK0~ VA are typical of the water--soluble polymers 30 which may be used in the aerosol hair spray formulations of the present invention. The preferred water--soluble polymers comprise homopolymers of N--vinyl--2--pyrrol; fl; nnne and copolymers of N--vinyl--2--pyrrol ;tl;nnne and up to 50 mole percent vinyl 35 acetate having weight average molecular weights in the _ _ . . , .. .. . _ . .. , ... .. ... ... . _ .. _ . _ .. . . . . .
W~ 95/33437 2 ~9 0 7 ~`6 P_l/o.. r ~~69 range of 1000 to 100,000. The water--soluble polymers are used at a level of from o . 5% to 10% by weight, generally 1~ to 5% by weight, and preferably from 2% to 4~ by weight of the total formulation. The weight 5 average molecular weight of the water--soluble polymers is not critical but is generally in the range from 1, 000 to 2, 000, 000 .
The aerosol formulations also can contain a variety of other nonessential, optional components suitable for 10 rendering such formulations more acceptable. Such conventional optional ingredients are well known to those skilled in the art, e.g., other emulsifiers such as anionics (e.g., sodium alkyl sulfate); preservatives such as benzyl alcohol, methyl paraben, propyl paraben 15 and imidazolidinylurea; cationic emulsifiers/conditioners such as cetyl trimethyl ammonium chloride, stearyl--dimethyl benzyl ammonium chloride, and di (partially--hydrogenated tallow) dimethylammonium chloride; thickeners and viscosity 20 modifiers such as d;P~h;ln~lamide of a long chain fatty acid, fatty alcohols (i.e., cetearyl alcohol), sodium chloride, sodium sulfate, and ethyl alcohol; pH
ad~usting agents 6uch as citric acid, s~ccinic acid, sodium hydroxide and triethanolamine; coloring agents 25 such as any of the FD&C or D&C dyes; hair ~;d;7;ng (bleaching) agents such as 11Y~1LUY~ peroxide, perborate salts and persulfate salts; hair reducing agents such as thioglycolates; perfume oils; chelating agents such as ethylen~ m;netetraacetic acid; and among many other 30 agents, polymer plasticizing agents such as glycerin and propylene glycol. These optional materials are generally used individually at a level of from 0 . 001% to 19%, preferably from 0.01% to 596 by weight of the total f ormulation . It is important to note that the use of 35 cationic emulsifiers in amounts of greater than 1% may ;

The aerosol hair--spray f ormulation of the present invention may also include from 0.01% to 10%, preferably, 0.1% to 2% by weight of a non--volatile 5 ~:;licnnP ~, ~u",~l or other conditioning agent(s), preferably a water--insoluble, emulsifiable conditioning agent. The preferred non--volatile silicone - u,ld is a polydimethylsiloxane compound, such as a mixture of a low molecular weight polydimethylsiloxane f luid and a 10 higher molecular weight polydimethylsiloxane gum. The non--volatile polydimethylsiloxane ul-d is added to the f ormulation of the present invention in an amount sufficient to provide i uv~d combing ~nd improved feel (softness) to the hair after shampooing.
Another particularly suitable conditioning agent that can be included in the formulation of the present invention is a volatile hydrocarbon, such as a hydrocarbon including from lo to 30 carbon atoms, that has sufficient volatility to slowly volatilize from the 2 0 hair after application of the aerosol hair spray formulation. The volatile hydrocarbons provide essentially the same benef its as the silicone conditioning agents.
The preferred volatile hydrocarbon compound is an aliphatic hydrocarbon including from 12 to 24 carbon atoms, and having a boiling point in the range of from 100 C to 300C.

SULFOPOLYESTER IN A HYDT~AT C`~TT~LIC LIQUID VEHICLE
FIELD OF THE INVENTION
This invention relates to an aerosol hair spray f ormulation containing 0 . 5 to 15 weight percent of a water--dispersible or water--dissipatible, linear sulfopolyester having a Tg of 40C to 50CC and an inherent viscosity of 0 . 24 to 0 . 60 dl~g which contains repeat units from 20 to 26 mole percent dimethyl--5--sodiosulfoisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboYylic acid; 10 to 30 mole percent 1,4--cycl--hf~Y;~n~Ai- ' h;ln-l and 70 to 90 mole percent diethylene glycol, based on 100 mole percent diol; and up to 60 weight percent of an alcohol. The aerosol hair spray formulations are clear, have; uvt:d dry time and curl retention, and eYhibit less than 20 NTU' s, which is a measure of turbidity, even at high concentrations of 2 0 alcohol .
BACKGROUND OF THE INVENTION
Hair sprays provide human hair with a particular shape or configuration and function by applying a thin film of a resin or gum onto the hair to adhere adjacent hairs together so that they retain the particular shape or configuration at the time of application.
U. S . Pat . No . 5 ,164 ,177 discloses a hair spray formulation containing 2--40% of a linear polymer 3 0 including at least one vinyl or acrylate monomer, a water--soluble electrolyte, 30--90% water, and 0 30%
alcohol. The water--soluble electrolyte is added to lower the viscosity of the composition to achieve a higher percentage of polymer in the composition. Such formulations, however, have poor humidity resistance, hold and curl retention.
_ _ _ _ _ _ _ _ . _ .... . . . . _ . _ ... _ ~0 95/3343~ ~ 1 9 ~ 7 4 ~ ` 6~69 , U.S. Pat. No. 4,a~1,580 discloses hair spray formulations containing a water--dispersible or water--dissipatible linear sulfo--polyester f ixative in a water~alcohol mixture. The diol component of the sulfopolyester contains at least 20 mole percent poly(ethylene glycol). Such formulations are fast drying and have good hair holding properties but possess the disadvantage of being very difficult to remove from the hair. For example, prolonged washing is re,rluired to completely remove the water--dispersible, linear polyester f ixative to obtain hair with no tacky or sticky feel. U. S . Pat. No. 4, 300, 580 suggests adding other substances such as poly (alkylene ether) to increase the hardness and reduce the t~rk;nPsS of the formulations. However, when such formulations containing a combination of the poly(alkylene glycol) and sulfopolyester are applied to hair and allowed to dry, the f iYative causes a matting of the hair . Such matting hinders combing, brushing and styling of hair.
U.S. Pat. No. 5,266,303 discloses hair spray formulations containing a water--dispersible sulfopolyester having a glass transition temperature of 36C to 40C, a water--soluble polyvinyl lactam polymer, and water . The perf ormance characteristics of such formulations are good. However, the drying time is too long, and the addition of alcohol, which would improve - dry time, causes the formulations to become cloudy.
Thus, the use of alcohol is not an option f or improving the dry time of such f ormulations .
U.S. Pat. No. 5,158,762, discloses hair spray compositions containing a blend of a sulfopolyester and a water--soluble polymer in water. The sulfopolyester contains at least 4 0 mole percent 1,4--cyclnhPY~nP~i t~-anol. The performance characteristics of such formulations are good, however, _ _ _ wo g~l33437 21~ 0 7 ~ 6 r~ s?~g ~ -- 3 --the drying time is too long, and the addition of alcohol, which would improve dry time, causes the formulations to become cloudy. Thus, the use of alcohol is not an option for improving the dry time of such 5 formulations.
U.S. Pat. No. 5,266,308, discloses aqueous hair spray compositions which contain a sulfopolyester, a water--soluole polymeric resin and a homopolymer of polyvinylpyrrolidone . The perf ormance characteristics 10 of such formulations are good, however, the drying time is too long, and the addition of alcohol, which would improve dry time, causes the f ormulations to become cloudy. Thus, the use of alcohol is not an option for improving the dry time of such formulations.
In contrast, the present inventors have unexpectedly detPrm;n~cl that aerosol hair spray formulations which are clear and provide properties considered desirable for hair preparation such as fine spray patterns, fast drying times, prolonged curl 2 0 retention under humid conditions, good holding power and resistance to build--up may be prepared with as much as 60 weight percent alcohol to facilitate rapid drying on the hair . The hair spray f ormulations of the present invention are clear and exhibit less than 20 NTU' 5 which is a measure of turbidity. In the cosmetic field greater than 20 NTU' s is characteristic of a cloudy mixture that is visible to the eye.
SUMNARY OF THE INVENTION
Accordingly, it is one object of the present invention to provide a clear aerosol hair spray f ormulation .
It is another object of the invention to provide a aerosol hair spray f ormulation which i5 not tacky, has a fast drying rate, acceptable body, consistency and Wo 95/33437 21 9 0 7 ~ u PCTrUS95/06269 .~
exhibits improved curl ~t~bn~ion.
Another obj ect of e invention is to provide a aerosol hair spray formulation which i8 clear and has PY(`Pl 1 Pnt storage stability and which does not clog the S exit port o~ a aerosol container.
These and other objects are accomplished herein by an aerosol hair spray formulation having improved dry time and curl retention and exhibiting les6 than 20 NTU' s as a measure of clarity which comprises:
(1) a sulfopolyester having a Tg of 40C to 50C
and an inherent viscosity of 0. 24 to 0 . 60 dl~g which consists essentially of repeat units from (a) a dicarboxylic acid component comprising of 20 to 26 mole percent dimethyl--5--soA; osl1l foisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboxylic acid;
(b) a diol L-l L compri5ing of 10 to 30 mole percent l,4-cycl~hPYAn~o~;r thanol and 70 to 90 mole percent diethylene glycol, based on 100 mole percent diol;
(2) a water~alcohol li~auid vehicle; and ( 3 ) 3 to 60 weight percent based on the weight of -nts (1), (2), and (3) of a propellant selected from the group consisting of a Cl-- C4 aliphatic hydrocarbon , dimethyl ether , and mixtures thereof, provided the sulfopolyester, component (1), is present 30 in an amount of 0.5 to 15 weight percent, based on the total weight of the aerosol hair spray formulation.
DESCRIPTION OF THE INVENTION
The aerosol hair sprays of the present invention 35 exhibit less than 20 NTU' s which is a measure of the ~O9~l33437 21~0 7~ G ~ C.. '71~9 .
., _ turbidity of a mixture . In the cosmetic f ield greater than 20 NTU' s is characteristic of a cloudy mixture that is visible to the eye. The clear aerosol hair spray formulations of this invention contain a sulfopolyester, 5 component tl), in an amount of 0.5 to 15 weight percent, preferably 3 to 10 weight percent, and more preferably 5 to 8 weight percent, based on the total weight of the aerosol hair spray formulation.
The sulfopolyester, c~ron-~nt (1), has a glass 10 transition t ~ , tu~ e of 40C to 50C and contains repeat units from a dicarboxylic acid, a diol and a difunctional sulf~ m~ . The dicarboxylic acid component of the sulfopolyester contains 20 to 26 mole percent of dimethyl--5--sodiosulfoisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboxylic acid. The diol component of the sulfopolyester contains 10 to 30 mole percent 1,4--cycl-~h~Y~np~l;; ?thanol and 70 to 90 mole percent diethylene glycol, based on 100 mole percent diol. The 20 sulfopolyester has an inherent viscosity (I.V.) of 0.24 to 0. 60 dl~g.
Component (2) of the aerosol hair spray is a liquid vehicle. The liquid vehicle may be water or a water~alcohol mixture. Distilled or deionized water are 25 the preferred sources of water since tap water generally contains ions which may precipitate the sulfopolyester, -nPnt (1). If a water~alcohol mixture is used, the amount of volatile organic components which include the alcohol and propellant cannot exceed 60% of the aerosol 30 hair spray formulation. Therefore, at least 40% of the formulation is water and the L. in;ng 60% is alcohol and propellant. Preferably a water~alcohol mixture is used wherein the alcohol is present in an amount of 20 to 30 weight percent based on the weight of the aerosol 35 hair spray formulation. The alcohol provides faster WO 95~33437 ~ l g 0 7 ~ 6 PCr/US95/06269 drying of the formula~ion on hair as compared to f ormulations prepared with only water as the liquid vehicle. The alcohol i5 an aliphatic straight or branched chain monohydric alcohol having 2 to 4 carbon 5 atoms. Isopropanol and ethanol are the preferred alcohols .
The aerosol hair spray f ormulations of the present invention require a propellant, componQnt t3). The propellant can be any liquefiable gas conventionally 10 used for ~erosol containers. Examples of materials that are suitable f or use as propellants are trichlorof luoromethane, dichlorodif luoromethane, dichlorotetraf luoroethane, monochloro~l l f l ~ romethane, trichlorotrifluoroethane, dimethyl ether, methane, 15 ethane, propane, n--butane and isobutane, used singly, or admixed. Water--soluble gases such as dimethyl ether, carbon dioxide, and~or nitrous oxide also can be used to obtain aerosols having reduced ~l i h~ 1 i ty .
Other insoluble, c esse~ gases such as nitrogen, 20 helium and fully--fluorinated oxetanes and Oyl'rAn~C also are useful to deliver the formulations from aerosol containers. Other means of delivery of the above--described aqueous styling aid formulations include, aerosol sprayers, all forms of bag--in--can 25 devices, in situ carbon dioxide (CO2) generator systems, ~ssors, and the like.
Preferably, the propellant is either a C1 -- C4 aliphatic hydrocarbon or dimethyl ether. A preferred aliphatic hydrocarbon propellant is a mixture containing 30 83 percent isobutane and 17 percent propane. The amount of the propellant is governed by normal f actors well known in the aerosol art. The level of propellant is generally from ~% to 60%, preferably from 5% to 45%, of the aerosol hair spray formulation. In the case where a 35 C1 -- C4 aliphatic hydrocarbon is used as the propellant, ....
~ W~9sl33437 2~ 9n7~ p~ 6269 generally 3 to 10 weight percent, preferably 4 to 7 weight percent, is employed. In the case where dimethyl ether is used as the propellant, generally, 20 to 40 weight percent, preferably, 30 to 35 weight percent, is 5 employed. If a propellant such as dimethyl ether utilizes a vapor pressure suppressant (e.g., trichloroethane or dichloromethane), for weight percentage calculations, the amount of suppressant is included as part of the propellant.
The aerosol hair spray formulations may optionally contain a water--soluble polymer or resin, ~ -n~nt (4)-The water--soluble polymer must be soluble or dispersible in liquid vehicle, component (2). The term "water--soluble" refers to any material that has solubility of at least 1 gram per 100 grams of water, i.e. 1%, preferably a solubility of at least 59~ by weight . Conversely, the term "water--insoluble" ref ers to substances that are insoluble at a level of less than 1 gram per 100 grams of water, i. e., less than 1% by weight. Solubility or dispersibility is det~r;n~d at ambient conditions (e.g., a temperature of 25C and atmospheric pL e~ ~UL ~) .
Water--soluble polymers useful in the formulations of the present invention are homopolymers or copolymers that can be rendered dispersible or 501uble in aqueous or water~alcohol mixtures. The water--soluble polymer is a synthetic, linear, homopolymer or random copolymer inr~ ;n~ at least one, and preferably two or more, vinyl or acrylate monomers of the following group:

Examples of preferred copolymers are the mono ethyl, isopropyl or n--butyl esters of poly (methyl vinyl ether~maleic acid);
poly(vinyl pyrrolidone~vinyl acetate, poly(vinyl pyrrolidone~ethyl methacrylate~methacrylic acid), 10 poly (ethyl acrylate~acrylic acid~N--t--butyl acrylamide), and poly (vinyl acetate~crotonic acid) .
Other suitable classes of polymers include anionic, nonionic, amphoteric and cationic polymers. Specific polymers include polyvinylpyrrolidone (PVP), copolymers 15 of PVP and methylmethacrylate, copolymers of PVP and vinyl acetate tVA), polyvinyl alcohol (PVA), copolymers of PVA and crotonic acid, copolymers of PVA and maleic anhydride, hyd~ ~sy~ yl cellulose, ~IydLo~y~L.~yl guar gum, sodium polystyrene sulfonate, 20 PVP~ethylmethacrylate~methacrylic acid terpolymer and octylacrylamide~acrylate~butylaminoethyl methacrylate copolymers, and mixtures . A pref erred vinyl polymer or copolymer contains at least 50 mole percent of the residues of n--vinyl lactam monomer such as 25 N--vinylpyrrol; rl i none .
With certain of the acidic water--soluole polymers, it may be nPcP~Ary to neutralize some acidic groups to promote 601ubility~dispersibility, e.g., PVA~crotonic acid. Neutralization and increased solubilization are 30 accomplished with one or more inorganic bases such as sodium hydroxide, potassium hydroxide, ammonium hydroxide and~or ammonium carbonate. Among stable organic bases are the water soluble bases such as monoethanolamine (MEA), diethanolamine (DEA), 35 triethanolamine (TEA), 2--methyl--2--amino--1--propanol .
WO 95/3343~ 2 1 9 ~ 7 4 ~ q (AMP), ;nn ~i~COlS, and the like, which help solubilize the polymer in water solutions. The level of neutralization required for solubilization varies for each polymer. All of the above--described acidic 5 polymers become soluble in water and hydroalcoholic solutions at 100% neutralization, and all described levels of water~alcohol~propellant solutions. The pH of these solutions usually ranges from 9 to 12. The lowest neutralization level needed to render the polymer water 10 soluble or dispersible depends on the kind of polymer, and the amount of alcohol, water and propellant. For instance, for poly(methyl vinyl ether~maleic acid) in water the lowest neutralization level is 40% with sodium hydroxide and AMP; for poly(ethyl acrylate~acrylic 15 acid/N--t--butyl acrylamide) the lowest neutralization level is 75% with AMP and 65% with sodium hydroxide. At these neutralization levels, the pH of the solutions range from 5 to 7. A slightly acidic or neutral pH such as this is preferred, however, the pH of the 20 formulations of the present invention can vary from 4 to 9 . Saponif ication of the ester linkages may occur under a 1 kA l; nF~ conditions .
The water--601uble polymers may be prepared according to known procedures wherein, for example, a 25 N--vinyl lactam is polymerized, optionally in the presence of one or more other vinyl monomers such as those described above.
