10 Claims, No Drawings SOFTENING AGENT COMPOSITIONS THE PRIOR ART After the drying of washed textiles, particularly those of cotton or similar cellulose fibers, a distinct hardening or harshening of the handle or hand can be observed. This phenomenon is particularly exhibited if the textiles have been washed in drug-washing machines with a strong mechanical agitation. This undesirable hardening of the textile goods can be avoided, as is well-known, when a softening rinsing agent is added to the last rinsing liquor of the washing process, that conventionally contains cationic compounds with at least two longer-chain alkyl radicals in the molecule. There are liquid softening rinsing agents for laundry on the market which contain as active ingredient distearyldimethylammonium chloride, in an aqueous dispersion. It is known, however, that such cationic softening rinsing agents adversely effect the absorptivity of the treated laundry, even when the instructions for use are followed exactly.

d. the remainder up to 100% by weight of at least one diluent selected from the group consisting of water, and
water-soluble or readily water-dispersible liquid and solid carriers.
A further object of the invention is the development of a process for the softening of washed textiles which consists of rinsing said washed textiles with water containing from 0.] to 2.0 gm/l of the above 3-acyloxy-2- hydroxypropyl-trialkylammonium compounds.
A still further object of the invention is the obtention of powdery softening agent compositions for washed textiles containing (a) from l to 50% by weight of the above 3-acyloxy-2-hydroxypropyl-trialkylammonium compounds, (b) from 0.2 to 10% by weight of at least one nonionic surface-active dispersing agent, (c) from 0 to 25% by weight of other customary ingredients of softening agents for washed laundry and (d) the re mainder up to by weight of at least one solid diluent carrier compatible with rinsing agents for washed laundry, where said trialkylammonium compound is present in said composition a) in a homogenous mixture with the other components or b) in a finely-divided form on the surface of said at least one solid diluent carrier, and where the particles according to a) and b) may be combined as agglomerates.
These and other objects of the invention will become more apparent as the description thereof proceeds.
DESCRIPTION OF THE INVENTION It has now been found that these disadvantages of the prior art may be avoided and the object of the invention achieved if the washed laundry, after rinsing out the washing liquor, is treated with a washing aftertreatment agent comprising a combination of l a 3- acyloxy-2-hydroxypropyl-tri-alkylammonium compound of the formula wherein m and n are integers from 0 to 4 and the sum of m n is an integer from 0 to 4, R, and R are selected from the group consisting of alkyl and alkenyl having from 10 to 24 carbon atoms, R, is alkyl having 1 to 4 carbon atoms, A is selected from the group consisting of hydrogen and OH R,

d. the remainder up to 100% by weight of at least one diluent selected from the group consisting of water. and water-soluble or readily water-dispersible liquid and solid carriers.
In the formula, the alkyl and alkenyl groups are preferably straight-chained groups, preferably straight chained allryl. which may be of natural or synthetic origin, for example, dodecyl, tetradecyl, hexadecyl, oleyl and octadecyl, are preferably represented by the substituents R, and R The substituent R preferably signities the methyl residue.
As is further mentioned below, because of the method of preparation of the compounds of the formula, the anion X" is preferably a chloride or bromide anion.
The further treatment of the laundry may be effected in various ways depending on the drying process, which is to be used. If the drying is carried out in a hot air drier. the washed laundry can be directly sprayed with a dispersion of the active substance or the latter may be brought into contact with the washed laundry by way of a carrier. for example by spraying the inside walls of the drier with the dispersion of active substance before the drier is charged with the wash or by the addition to the charge of a carrier of large surface area saturated with the dispersion of active substance, whereby the textile softener is absorbed on the washed goods during the drying process. At the present time, however, the washing is generally hung out to dry, therefore the application of the softener in the last rinsing bath in a washing process when done by hand, and especially by machine washing, is most commonly used. Of course,
this procedure can be followed where the wash is dried in a drier also. In the last-mentioned appliction, the 3- acyloxy-2-hydroxypropyl-trialkylammonium compound is preferably used in the rinsing bath in amounts from 0.1 to 2.0 gm/liter, especially from 0.2 to 1.0 gm/liter.
in addition, other substances may be present in the rinsing bath, which substances are usable for the aftertreatment of washed laundry, such as optical brighteners, anti-microbial active agents, souring agents, sequestering agents, perfumes and dyes, etc. At least part of these substances should be acidic, and the amount of the acidic substances, particularly of the souring and sequestering agents is selected so that the rinsing bath has a neutral to weakly acidic pH range.
Suitable liquid carriers are water and water-soluble organic solvents from the group of lower alcohols containing l to 5 carbon atoms, preferably alkanols having 1 to 5 carbon atoms, for example, methanol, ethanol, propanol, isopropyl alcohol, butanol, amyl alcohol; lower ketones, preferably all-tanones having 3 to 6 carbon atoms, such as acetone and methylethylketone and the ethylene and diethylene glycols and their mono methyl or dimethyl, or monoethyl or diethyl ethers, as well as mixtures of the same with water.
Water and isopropy] alcoholwater mixtures are of special practical interest.
Solid carriers which may be used are readily watersoluble or water-dispersible inert organic or organic compounds from the group comprising urea, acet amide, biuret, sodium sulfate, solid polyethylene glycols and, optionally, solid forms of the below listed acid additives and acid sequestering agents.
The other components of the after-treatment agents according to the invention consist essentially of optical brighteners, antimicrobial active agents, acid additives, or souring agents, perfumes and dyestuffs.
The liquid and solid agents according to the invention are distinguished by a good dispersibility in cold water. With the treatment of washed laundry by the softening agents for the laundry of the invention, fab rics hardened by washing, particularly cotton terry cloth, become soft and nappy. Such treated fabrics possess, in comparison to the untreated washing goods, only a slightly diminished absorptivity and in compari sion to the washing goods treated with a known cationic softeners, a substantially improved absorptivity. In addition, by the treatment with the agents, according to the invention, an undesirable static charging of the textiles particularly those of synthetic fibers, is largely prevented.
The 3-acyloxy-2-hydroxypropyl-tri-alkylammonium compounds of the above formula are preferably prepared by reacting l a dicarboxylic acid of the formula la HOOC CHOH),,, (CB COOH and (2) a tertiary amine of the formula lb wherein m. n, B, R,, R, and K, have the above definitions, with (3) an epihalohydrin such as epichlorohydrin or epibromohydrin, preferably in the presence of an inert organic solvent, and in order to prevent formation of by-products, the tertiary amine is preferably used in slightly less than the theoretical amount with respect to the epihalohydrin. in order to obtain the lightest colored product possible, a reaction temperature of from 60C to 70C is preferred. A practically quantitative reaction generally results after a reaction of 25 hours under these conditions. The desired products are obtained after distilling off the solvents and any unreacted starting compounds, and they may gen erally be used in this form. In some cases a purification by redissolution or recrystallization, for example, in lower alkanols, acetone, ethyl acetate, gasoline, with active charcoal or other adsorbents, is advisble. The following 3-acyloxy-Z-hydroxypropyltrialkylammonium compounds given in Table i are some of the active substances utilizable according to the invention.

The powdery agents of the invention are utilized in such amounts that the concentration of the textile softener is in the range of from 0.1 to 2.0, preferably from 0.2 to 1.0 gm/l of the aqueous treatment liquor.
in the powdery preparations, the 3-acyloxy-2' hydroxypropyl-trialkylammonium compounds, the textile softening and improving agents of the invention, are in a homogeneous admixture with the other components or in a finely divided form mixture with the other components or in a finely divided form on the surface of solid particles of the carrier or of the diluent, and the different types of particles may be combined with one another to form agglomerates. These pulverulent preparations are obtained by mixing the ammonium compounds together with the dispersing agent and the solid carrier substances in a suitable way.
The invention relates further to processes for the preparation of powdery washing after-treatment agents for laundry of the above given composition.
According to a first process, the preparations of the invention are obtained by spryaing the active ammonium substance, together with the nonionic dispersing agents and, optionally, other customary ingredients, particularly optical brighteners, in a liquid mixture with water and/or volatile organic solvents from the group of methanol, ethanol isopropanol, acetone, methylene chloride, chloroform. in the temperature range of from 20C to 80C onto a moving bed of the solid carriers.
In this method, preferably. carriers are used with a surface area as large as possible and a low bulk weight, for instance a bulk weight of from 100 to 700 gm/l. Products of such a bulk weight are obtained, for instance, by calcination of water-crystallizationcontaining inorganic salts, particularly of sodium sulfate.
A further process for the preparation of the agents of the invention comprises hot drying an aqueous mixture of the various components, which are preferably present therein at a concentration of from to 35% by weight, at temperatures above 100C, preferably in the range from 105 to 125C.
According to a preferred variant of this process, the hot drying is carried out by pouring the aqueous mixture in a thin film onto a hot surface. A further preferred variant comprises carrying out the hot drying by spraying the aqueous batch into a hot stream of gas.
In all cases, the pulverulent properties of the products can be improved by incorporation therein of small amounts of substances with a large surface are, for example. micro-crystalline silicic acid, magnesium silicate and so forth.
The preparations according to the invention prepared by the said processes, especially by the hotdrying methods, are marked by a good pouring behavior and good stability on storage, freedom from dust and rapid dispersibility in cold water. lf the preparations of the invention contain components which are sensitive to temperature or readily volatile, for example, the antimicrobial substance or perfume further mentioned below, the latter are admixed with the finished powder products.
The pulverulent preparations are present as powders, agglomerates or granulates, of which the particle size should be from 0.1 to 3 mm, preferably at least of the preparation having a particle size of from 0.3 to 2 mm. The expression powdery" is used here in its general meaning, as it is normally used in connection with textile treatment agents. i.e. particle sizes are included which are finely powdered to coarsely powdered, inclusive of granulates and agglomerates.
The components contained in the washing aftertreatment agents of the invention are described below, in addition to the 3-acyloxy-2-hydroxypropyltrialltylammonium compounds and the carrier substance, and are described more particularly by their various classes.
As nonionic dispersing agents, as they may be contained in the agents of the invention, nonionic surfaceactive agents are particularly suited, here designated in the following as nonionics. These are products which owe their hydrophilic properties to the presence of polyether chains, amineoxide, sulfoxide or phosphine oxide groups, alkylolamide groups as well quite generally to an exces of hydroxyl groups. Such nonionics contain in the molecule at least one hydrophobic radical of 8 to 26, preferably 10 to 20 and particularly 12 to 18 carbon atoms and at least one nonionic watersolubilizing group. The preferably saturated hydrophobic radical is mostly of an aliphatic, optionally also alicyclic nature. It can be connected directly to the hydrophilic groups or over connecting members. As connecting member, for instance, benzene rings, carboxylic acid ester or carbonamide groups, ether-like or esterlike bound radicals of polyhydric alcohols, such as those of the ethylene glycol, the propylene glycol, the glycerine or of corresponding polyether radicals, are of interest.
Of particular practical interest are the products obtained by addition of ethylene oxide and/or glycide to fatty alcohols, alkylphenols, fatty acids, fatty amines, fatty acid or sulfonic acid amides having the above hydrophobic radicals. These nonionics may contain from 4 to 100, preferably 6 to 40 and particularly 8 to 20 ether groups, above all ethylene glycolether groups, per molecule. ln addition, in these polyether chains or at their end, propylene or butyleneglycolether groups or polyether chains may be present.
Further suitable non-ionic surface-active compounds are the water-soluble products of the addition of ethylene oxide to polypropylene glycol Pluronics" or to alkylenediaminepolypropylene glycol "Tetronics" and alkylpolypropylene glycols with l to 10 carbon atoms in the alkyl chain, all containing 20 to 250 ethylene glycolether groups and 10 to propylene glycolether groups and in which the polypropylene glycol chain acts as a hydrophobic residue.
In addition, the fatty acid or suult'onic acid alkylolamides which are derived, for instance, from mono or diethanolamine, from dihydroxypropylamine or other polyhydroxyalkylamines, for instance the glycamines are in the class of useable nonionics. They can be replaced by amides of higher primary or secondary alkylamines and polyhydroxy carboxylic acids.
Nonionic surface-active compounds of the amineoxide or aminesulfoxide type are also utilizable. The nonionic surface-active amineoxides include, for example, the products derived from higher tertiary amines having a hydrophobic alkyl residue and two shorter alkyland/or alkylol residues containing up to 4 carbon atoms each.
As nonionic dispersing agents, optionally suitable are also water-soluble or water-emulsifiable or dispersible compounds, which contain no hydrophobic radicals in the sense of the above-described nonionic surfaceactive agents or in which the nature or the number of the hydrophilic groups is insufficient to attain a complete water solubility. The former includes compounds such as solid or liquid polyethylene glycols, ethylene oxide adducts of glycerine and other polyalcohols, etc. The latter include, for example, partial fatty acid glyycerides or water-insoluble or not completely watersoluble alkoxylation products, for example those with 2 to ethylene glycolether residues in the molecule.
Inorganic and non-surface-active organic acids, innocuous to the fibers to be treated with 2 to 8 carbon atoms, optionally in the form of their slightly acidic water-soluble salts are suitable as acid additives or souring and sequestering agents, such as amidosulfonic acid, urea compounds of orthophosphoric acid, boric acid, oxalic acid, lactic acid, glycolic acid, citric acid, tartaric acid, benzoic acid, phthalic acid, gluconic acid, acetic acid and propionic acid as well as benzene, toluene or xylene sulfonic acids, sulfoacetic acid or sulfobenzoic acids. Preferably the acid additives are hydroxyalkanoic acids having 2 to 8 carbon atoms, hydroxyalkanedioic acids having 3 to 8 carbon atoms, dihydroxyalkanedioic acids having 4 to 8 carbon atoms, hydroxyalkanetrioic acids having 4 to 8 carbon atoms and alkanoic acids having 2 to 8 carbon atoms.
Anti-microbial active substances are here understood as bactericidal or bacteristatic or fungicidal or fungistatic acting compounds. These active substances should be water-soluble as such, or in the form of their salts. The anti-microbial active substances, usable according to the invention, are mostly quaternary ammonium compounds, particularly those which contain, in addition to a long-chain aliphatic and two short-chain aliphatic hydrocarbon radicals, an organic radical in the molecule, either aromatic residue connected over an aliphatic carbon atom to the nitrogen atom or an aliphatic residue with double bonds. Examples for such anti-microbial quaternary ammonium compounds are the following: dimethyl-benzyl-dodecyl-amrnonium it NZ i -Q HC=CH a N H s0 chloride, dimethyl-benzyl-tetradecyl-ammonium chloride, dimethyl-(ethylbenzyl)-dodecyl-ammonium chloride, dimethyl-benzyl-decylammonium bromide, diethyl-benzyl-dodecyl-ammonium chloride, diethyl-benzyloctyl-ammonium chloride, dibutyl-allyl-,methy1-ethylbenzyl-, ethyl-cyclohexyl-allyland ethyl-crotyl-diethylaminoethyl-, dodecyl-ammonium chlorides.

As anti-microbial active substances, also suitable are phenolic compounds of the type of the halogenated phenols with l to 5 halo substituents, particularly chlorinated phenols; alkyl-, cycloalkyl-, aralkyland phenylphenols with l to l2 carbon atoms in the alkyl radical and with l to 4 halo substituents, particularly chlorine and bromine in the molecule; alkenyl bisphenols, particularly derivatives substituted by 2 to 6 halogen atoms and optionally by lower alkyl or trifluoromethyl groups with an alkylene bridge consisting of l to l() carbon atoms; hydroxy benzoic acids or their esters and amides, particularly anilides which may be substituted in the benzoic acid and/or aniline radical especially by 2 or 3 halogen atoms and/or trifluoromethyl groups; 0' phenoxyphenols which may be substituted by l to 7, preferably 2 to 5 halogen atoms and/or the hydroxyl, cyano, carbomethoxy, and carboxyl group or by lower alltyl. A particularly preferred derivative of the class of o-phenoxyphenols is Z-hydroxy-Z ',4,4 trichlorodiphenyl ether.
The usable brighteners are mostly, if not exclusively, derivatives of aminostilbene-sulfonic acid or diaminostilbene-sulfonic acid, diarlypyrazolines, carbostyril, l,2-di( 2benzoaxazolyl)-or l,2 di-( 2- benzimidazolyl)-ethylene, benzoxazolyl-thiophene and coumarins.

This preparation was prepared by the method described in Example 18.
Using the methods of Examples 18 21 washing after-treatment preparations can also be prepared with the other compounds listed in Table l.
The washing after-treatment agents for laundry according to the invention are marked by a rapid dispersibility and distribution in cold water, so that the action of the textile softener, for example on use in the last rinsing cycle of a washing machine, is effective. The treatment with the preparations of the invention at a concentration of 0.5 gm of the textile softener per liter of rinsing bath already leads to a full and soft handle of the finished textiles, which are also marked by a good absorption capacity.
EXAMPLE 22 a. Determination of the softening action The determination of the softening action of the 3- acyloxy-2-hydroxypropyl-trialkylammonium compounds was carried out with an aqueous dispersion of the preparations according to the invention.
For this, samples of prepared cotton terry cloth were rinsed in the presence of clean carrier fabric with an aqueous dispersion which contained 0.5 gm/l of active substances, prepared as in Examples 1 to 21, in the last rinse of a drum-washing machine (duration: 5 minutes; liquor ratio 1:25). The samples were then centrifuged and dried by hanging. Subsequently, the hand was judged independently by 4 persons. The evaluation of the hand was expressed in numbers between 1 and 6,
l full and very soft hand, and
2 very hard hand.
The average values of the evaluations were calculated that are summarized in the following Table 11. The controlling values were as follows:
Fabric Type A: Samples of new cotton terry cloth were treated for 240 hours in a washing machine under boiling washing conditions with 2.0 gm/l of sodium tripolyphosphate solution. After drying, the hand number 6 was assigned to this thus pre-hardened fabric.
Fabric Type B: Samples of new cotton terry cloth were treated 15 times with a commercial heavy duty washing agent in an automatic washing machine. After drying, such pro-hardened fabrics were assigned the hand number 4. The hand number l was assigned to samples of new cotton terry cloth where the sizing was removed and they were treated with a solution of 0.5 gm/l of ditallowalkyl-di-methylammonium chloride. The softness of new, unlaundered cotton terry cloth corresponds generally to the hand numbers L5 to 2.

Result:
According to the values of Table l, the one treatment of the pre-hardened or hardened-by-washing cotton terry cloth of type A or B with the dispersions of the active substances of the invention leads to a full and soft hand.
b. Determination of the absorption capacity (measurement of the rise in height) The influence of the textile softening agents, used according to the invention, on the absorptivity of the cotton fabrics, treated with these active substances, was determined by the ascending method [.ldrder, Zeitschrift fur die gesamte Textilindustrie, 64, 593( I962); ibid. 67,22 (1965)].
A cotton test fabric, previously extracted with methanol and dichloromethane served as test material. This test fabric was agitated with a dispersion of 0.5 gm/l of the test preparation for one hour, subsequently centrifuged, dried and ironed between filter paper. After conditioning C and 65% relative air humidity for 24 hours, these strips, 20 cm long and 2 cm wide, were suspended with their lower ends in distilled water and the rise in height d of the water after a timej of l, 2, 5, I0, 20 and 30 minutes were measured. Fabric which had only been treated with water served for comparison,
and also fabric treated with 0.5 gm per liter of If the ascending height of water of the softening rinsed strip at the time j with the penetration of the invention i is designated as d the ascending height of the strip rinsed with water at the time j is designated as d for the absorptivity value 8 at the timej, that is the percentual residual absorptivity based on water (H O) is found:
and for the average absorptivity value S For comparison, the ascending height (in of test strips was determined which were rinsed with a solution of 0.5 gm]! of N,N-dioctadecyl-N,N-dimethyl-ammonium chloride and from it the percentual improvement A,- of the absorptivity of the active substance i compared to N,N-dioctadecyl-N,N-dimethyl-ammonium chloride was calculated.
and for the average value In the following Table 1]] average absorptivity values S and the average percentual improvement of the absorptivity A for some selected substances of the invention, based on the absorbtivity of water as I00, was re N,N-Dioctadecyl-N,N-dimethylammonium chloride (known textile softener) c. Determination of the absorptive capacity (measurement of spreading time) The influence of the textile softeners, used according to the invention, on the absorptivity of cotton test fabrics, softening rinsed with these preparations, was also determined by the method of Oxe' and Schuster [Schusten Textil-Rundschau 20, 352 1965)]. Here the spreading-out time t of water in a horizontally spread cotton test strip under exactly defined conditions with the use of an absorptivity value meter was determined. As test material, a cotton test fabric, previously extacted with methanol and dichloromethane, 5
was used. It was agitated for 30 minutes with a dispersion of the test preparation (conc. 0.5 gm/l); subsequently dried and air-conditioned. A fabric analogously treated with water served as a comparison sample. The measurement was done with an absorptivity value meter, according to Oxe' and Schuster, the distance of the measuring contacts was adjusted to 5 cm and a dropping time of l sec. was selected. in the normal case ten parallel measurements were carried out.
The absorption time is, according to the true dimension(sec/cm). a reciprocal speed. An increase, therefore, corresponds a decrease in the absorptivity of the fabric.
If t, is designated as the absorption time of the fabric rinsed with the preparation i and the absorption time of the fabric rinsed with water, for the absorption value, that is the residual absorptivity of the soft'rinsed fabric, referred to the sample treated with water I 100%, the following equation is used.
M 0 or 100 In the Table IV the measured absorption time I, the absorption values a and the percentual improvement B for some trialkylamrnonium compounds are given.
