Claim 1
Independent Claim
200 words
A process for liquefying an aqueous textile softener which contains, as the active ingredient, from 15 to 40 percent by weight of a condensate of 1 mole of a bis- or tris-hydroxyalkylamine of the formula ##STR5## where R 1 is H, alkyl of 1 to 4 carbon atoms, hydroxyethyl or 2-hydroxypropyl and R 2 is H or CH 3 , with from 0.8 to 2 moles of a fatty acid of 16 to 18 carbon atoms, the said condensate being in the form of a salt with an inorganic or organic acid or being partially or completely quaternized at the amine nitrogen, wherein there is added to the softener from 3 to 15 percent by weight, based on the said active ingredient, of a compound of the formula ##STR6## where n is an integer from 1 to 4, R 3 and R 4 independently of one another are methyl, ethyl or propyl, R 5 is hydrogen or methyl and R 6 is alkyl of 7 to 13 carbon atoms including a chain of at least 7 carbon atoms, as a salt with an inorganic or organic water-soluble acid, and the pH of the formulation is brought to 2.5 to 6.
Claim 2
Dependent Claim
200 words
A process for liquefying an aqueous textile softener which contains, as the active ingredient, from 15 to 40 percent by weight of a condensate of 1 mole of a bis- or tris-hydroxyalkylamine of the formula ##STR5## where R 1 is H, alkyl of 1 to 4 carbon atoms, hydroxyethyl or 2-hydroxypropyl and R 2 is H or CH 3 , with from 0.8 to 2 moles of a fatty acid of 16 to 18 carbon atoms, the said condensate being in the form of a salt with an inorganic or organic acid or being partially or completely quaternized at the amine nitrogen, wherein there is added to the softener from 3 to 15 percent by weight, based on the said active ingredient, of a compound of the formula ##STR6## where n is an integer from 1 to 4, R 3 and R 4 independently of one another are methyl, ethyl or propyl, R 5 is hydrogen or methyl and R 6 is alkyl of 7 to 13 carbon atoms including a chain of at least 7 carbon atoms, as a salt with an inorganic or organic water-soluble acid, and the pH of the formulation is brought to 2.5 to 6.
Claim 3
Dependent Claim
20 words
The process of claim 1 wherein the compound II is derived from lauric or myristic acid and dimethylaminopropylamine or diethylaminopropylamine.
Claim 4
Dependent Claim
46 words
The process of claim 1 or 2 wherein the compound II is employed as a salt with hydrochloric, formic or acetic acid, the acid being used in an amount such that a 2% aqueous solution of the salt has a pH of from 2.5 to 6.
Claim 5
Dependent Claim
40 words
The process of claims 1 or 2, wherein the softener is prepared by fusing the active ingredient with compound II and treating with acid, working the product into a paste with water, stirring at elevated temperature and cooling whilst stirring.
Claim 6
Dependent Claim
13 words
A liquid textile softener obtained by the process of claims 1 or 2.
Claim 7
Dependent Claim
11 words

Claim 8
Dependent Claim
22 words
A method of imparting softness to textile goods wherein the goods are treated with the textile softener of claim 5 in water.
Claim 9
Dependent Claim
22 words

Claim 10
Dependent Claim
12 words
