Abstract
A textile treatment composition comprises certain polyamine salts and nonionic fabric conditioning substances which are fatty acid esters of alcohols or anhydrides having up to 8 carbon atoms. Particularly useful polyamine salts have a higher alkyl substituent and have ethoxylate or polyethoxylate substituents on the nitrogen atoms. Glycerol stearates and sorbitan stearates are preferred nonionic agents. The highly charged cationic species provide an excellent carrier system to encourage deposition of the nonionic fabric conditioner on fabrics which are rinsed in dilute aqueous solutions of the composition.
Claims5
A textile-treating composition in the form of an aqueous dispersion and comprising
- (i) a cationic surfactant of the general formula ##STR9## wherein R is a C.sub.10 -C.sub.22 alkyl group;
- R.sub.1 is (C.sub.2 H.sub.4 O).sub.p H or (C.sub.3 H.sub.6 O).sub.p H where the total p in the molecule is not more than 15;
- R.sub.2 is hydrogen or C.sub.1 -C.sub.4 alkyl;
- n is from 2 to 6;
- m is from 1 to 3 and A is an anion, and
- (ii) a nonionic fabric-conditioning substance selected from fatty acid esters of mono- or polyhydric alcohols having from 1 to 8 carbon atoms and anhydrides thereof,
- wherein the ratio fo said cationic surfactant to said nonionic fabric-conditioning substance is from 4:1 to 2:3.
