Abstract

Abstract Environmentally safe, stable, pourable aqueous fabric softening compositions based on the combination of a quaternary ammonium compound and an amido amine. The softener combination comprises from as little as 1% and up to 60% and preferably 2 to 20% by weight of the composition. Methods for making the composition are also described. Softening performance is outstanding and the compositions are simple to prepare, even the more highly concentrated forms. The softener compositions are primarily intended for use in the rinse cycle of an automatic washing machine.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 209 words
A fabric softening composition in the form of an aqueous dispersion containing from about 3% to about 60% by weight of fabric softeners composition consisting essentially of fatty acid ester containing quaternary ammonium softener salt having the formula ##STR7## wherein R represents an aliphatic ester residue of from 12 to 30 carbon atoms of the formula ##STR8## and n is a number of from 1 to 3, [R 1 ] R 1 represents R or a lower aliphatic group, aralkyl group or hydroxyalkyl group, R 2 and R 3 independently represent lower aliphatic group, aralkyl group or hydroxyalkyl group, X - is an anion and a represents the ionic valence of the anion; and a fatty acid amido amine softener having the formula ##STR9## wherein R 1 is a C12 to C30 alkyl or alkenyl group, R 2 represents R 1 , R 1 CONH(CH) 2 ) m or CH 2 CH 2 OH; R 3 represents hydrogen, methyl, or (CH 2 CH 2 O) p H, m is a number of from 1 to 5, and p is a number of from 1 to 5; at a weight ratio of ester quaternary softener to fatty acid amido amine softener in the range of from about 10:1 to 1:10.
Claim 2
Dependent Claim 209 words
A fabric softening composition in the form of an aqueous dispersion containing from about 3% to about 60% by weight of fabric softeners composition consisting essentially of fatty acid ester containing quaternary ammonium softener salt having the formula ##STR7## wherein R represents an aliphatic ester residue of from 12 to 30 carbon atoms of the formula ##STR8## and n is a number of from 1 to 3, [R 1 ] R 1 represents R or a lower aliphatic group, aralkyl group or hydroxyalkyl group, R 2 and R 3 independently represent lower aliphatic group, aralkyl group or hydroxyalkyl group, X - is an anion and a represents the ionic valence of the anion; and a fatty acid amido amine softener having the formula ##STR9## wherein R 1 is a C12 to C30 alkyl or alkenyl group, R 2 represents R 1 , R 1 CONH(CH) 2 ) m or CH 2 CH 2 OH; R 3 represents hydrogen, methyl, or (CH 2 CH 2 O) p H, m is a number of from 1 to 5, and p is a number of from 1 to 5; at a weight ratio of ester quaternary softener to fatty acid amido amine softener in the range of from about 10:1 to 1:10.
