Subject of the main patent .... ... (patent application

Y is an alkali metal or hydrogen, R and R. for Acyl radicals of saturated or unsaturated monocarboxylic acids with about 12 - 22 carbon atoms, R_ for the methyl or ethyl radical :, Rg for hydrogen, the methyl radical or the ethyl radical, X for is the anion of an organic or inorganic acid, and the sum of m and η has a value of 0-12, for Treatment of textiles.

In a further embodiment of the main patent, it has now been found that with the same advantage in the treatment of textiles, especially as a fabric softener for items of laundry, aqueous preparations of compounds of the general formula:

can use, in which R. for a straight-chain or branched alkyl radical with 1 - k carbon atoms, R ₀ for a straight-chain or branched alkyl or alkoxymethylene radical with up to 8 carbon atoms, a benzyl radical, hydrogen or the radical - CH ₀ COOY, where Y is an alkali metal or hydrogen, R "and R. for acyl radicals of saturated or unsaturated monocarboxylic acid with about 12 to 22 carbon atoms, R for the methyl or the ethyl radical, Rg for hydrogen, the methyl or ethyl radical, X stands for the anion of an organic or inorganic acid, and the sum of m and η is 0-12.

With these auxiliaries, very good softening effects are also obtained without the products having the disadvantageous, insufficient cold resistance of the known

The compounds to be used according to the invention, which the o "correspond to the aforementioned general formula, one obtains for example by esterification of N-substituted ones Diisopropanolamines or diisobutanolaraines and optionally their addition products with up to about 12, preferably up to 4 moles of ethylene oxide, propylene oxide and / or butylene © xid, hereinafter generally referred to as hydroxyalkylamines be, with 2 moles one. Carboxylic acid and subsequent reaction of the esterification products with an inorganic one or organic acid and / or a quaternizing agent. In the production of the Ver ™ to be used according to the invention bonds, it is also possible for the esterification to less than 2 moles of the carboxylic acid for each 1 mole of the tertiary hydroxyalkylamine to use. For example, when using 1.5 moles of the carboxylic acid per mole of Aiain, mixtures are obtained which in addition to the monoester, those corresponding to the above formula Bisester included. These mixtures can be used in the same way are used, such as the pure compounds corresponding to the general formula,

In the manufacture of the products to be used according to the invention can be used as N-substituted dialkanolamines, for example, li-methyl ?, N-ethyl-, N-butyl-dipropanolamine, N-methyl-, N-ethyl-, N-butyl- Jj dibutanolamine and the addition compounds of these amines used with up to about 12 moles of propylene oxide or butylene oxide will. .

FuV the esterification of the hydroxyalkylamines come aliphatic ^ Carboxylic acids containing about 12-22 carbon atoms are suitable, for example lauric acid, myristic acid, palmitic acid, Stearic acid, arachidic acid and behenic acid. Besides these ^ Acids derived from natural fats can also be synthetic produced carboxylic acids with a corresponding number of carbon atoms be used. It is of course also possible to use mixtures of the carboxylic acids mentioned. So for example

wise a mixture of natural fats Palmitic and stearic acid are particularly suitable. In the same Complex carboxylic acid mixtures, such as those obtained from the hydrolysis of tallow or coconut oil, can also be used will.

Any inorganic or organic acids can be used for the salt formation of the esterified hydroxyalkylamines with the esterified hydroxyalkylamines water-soluble or in Form water dispersible salts. Examples include: hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, and acetic acid.

Preferably, however, the esterified hydroxyalkylamines by reaction with suitable quaternizing agents, such as Methyl chloride, dimethyl or diethyl sulfate, benzyl chloride, Chloroacetic acid in the form of its alkali salts or the chloromethyl ethers of non-functional alcohols in quaternary ammonium compounds convicted. The quaternization can be carried out in a manner known per se, if appropriate in the presence of an organic solvent, such as a lower aliphatic alcohol. A separation of this solvent is generally not necessary, since its presence in the fabric softener is mostly not bother.

The aqueous preparations to be used according to the invention Compounds freeze even at temperatures below -5 C. In contrast to the well-known products, however, they are after the Thawing surprisingly returned to its original consistency. Also the softening properties the aids are retained in full. It was also found that by adding the invention to Compounds using the above-described decision of the gelling of aqueous preparations of the known cation-active

Fabric softener, such as distearyldimethylammoriium chloride, can be wholly or partially canceled depending on the amount added. The products to be used according to the invention can thus also be used together with known other cation-active Fabric softeners are used. The proportion of the invention Compounds to be used in these mixtures should, however, be at least about 10% by weight, preferably at least 60% by weight based on the total active substance.

The kai; ionaktivii fabric softeners to be used according to the invention generally draw nouns on the paser. For the Therefore, in most cases, very low wheel concentrations are sufficient. For example, one Liquor ratio of 1:10 in general application concentrate from about 0.05 to about 0.5 g / l. ""

The fabric softeners according to the invention are used in each case after the washing process. The means are used in the usual rinsing baths, expediently added to the last rinsing bath. The textiles treated with the products according to the invention feel supple and plump. They are pleasantly soft to the touch.

Examples

To demonstrate the favorable viscosity behavior and the stability of aqueous preparations which the erfindungsgeraäß to be used compounds (Example A, B, C, D, E, and F) contain, these preparations are subjected to a freeze test, in which they alternate 6 times each 24 hours Temperatures of -10 C and + 2OC.

For comparison, an aqueous preparation of a known fabric softener is used (Example G) treated in the same way.

All aqueous preparations are viscous, slightly before the test pourable dispersions.
