Abstract

Abstract Concentrated textile treatment compositions suitable for use in the rinse cycle of a textile laundering operation containing from 12.3% to 25% of water-insoluble cationic fabric softener or of a mixture thereof with a water-insoluble nonionic fabric softener in a weight ratio of cationic:nonionic softener of at least 2.5:1, and 0.1% to 3% of an alkoxylated amine, or ammonium derivative thereof, having the general formula I <IMAGE> I wherein R1 is C8-C22 alkyl or alkenyl, R2 is C1-C4 alkyl or (CnH2nO)yH, where n is 2 or 3 and x, y are from 0 to 14 with (x+y) from 2 to 14. The compositions provide fabric softening/static control benefits combined with excellent storage stability and viscosity characteristics.

Claim 1
Independent Claim 199 words
An aqueous textile treatment composition comprising: (a) from 13.5% to 20% of substantially water-insoluble cationic fabric softener or of a mixture thereof with nonionic fabric softener in a weight ratio of cationic softener:nonionic softener of at least 2.5:1, said cationic softener being selected from the group consisting of di-C 12 -C 24 alkyl and alkenyl quaternary ammonium salts, di-C 12 -C 24 alkyl and alkenyl imidazolinium salts and mixtures thereof, (b) from 0.3% to 2.5% of an alkoxylated amine, or ammonium derivative thereof, of the general formula: ##STR8## wherein R 1 is a C 16 -C 22 alkyl or alkenyl group, n is 2 and x and y are each a number average in the range from 1 to 2, the sum total of x and y being 2 or 3, (c) from 600 to 1000 parts per million of electrolyte, and (d) from 0.1% to 5% of a polyethyleneglycol having an average molecular weight in the range from 1000 to 40,000, wherein the composition has a pH in the range from 3.5 to 7.0 and is in the form of a particulate dispersion of cationic fabric softener in an aqueous solution of alkoxylated amine or ammonium derivative thereof.
Claim 2
Dependent Claim 199 words
An aqueous textile treatment composition comprising: (a) from 13.5% to 20% of substantially water-insoluble cationic fabric softener or of a mixture thereof with nonionic fabric softener in a weight ratio of cationic softener:nonionic softener of at least 2.5:1, said cationic softener being selected from the group consisting of di-C 12 -C 24 alkyl and alkenyl quaternary ammonium salts, di-C 12 -C 24 alkyl and alkenyl imidazolinium salts and mixtures thereof, (b) from 0.3% to 2.5% of an alkoxylated amine, or ammonium derivative thereof, of the general formula: ##STR8## wherein R 1 is a C 16 -C 22 alkyl or alkenyl group, n is 2 and x and y are each a number average in the range from 1 to 2, the sum total of x and y being 2 or 3, (c) from 600 to 1000 parts per million of electrolyte, and (d) from 0.1% to 5% of a polyethyleneglycol having an average molecular weight in the range from 1000 to 40,000, wherein the composition has a pH in the range from 3.5 to 7.0 and is in the form of a particulate dispersion of cationic fabric softener in an aqueous solution of alkoxylated amine or ammonium derivative thereof.
Claim 3
Dependent Claim 192 words
An aqueous textile treatment composition comprising (a) from 13.5% to 20% of substantially water-insoluble cationic fabric softener, said cationic softener being selected from the group consisting of di-C 12 -C 24 alkyl and alkenyl quaternary ammonium salts, di-C 12 -C 24 alkyl and alkenyl imidazolinium salts and mixtures thereof, (b) from 0.3% to 2.5% of an alkoxylated amine, or ammonium derivative thereof, of the general formula: ##STR9## wherein R 1 is a C 16 -C 22 alkyl or alkenyl group, n is 2 and x and y are each a number average in the range from about 1 to 11, the sum total of x and y being 1 to 12, (c) from 600 to 1000 parts per million of electrolyte, and (d) from 0.1% to 5% of a polyethyleneglycol having an average molecular weight in the range from 1000 to 40,000, wherein the composition has a pH in the range from 3.5 to 7.0 and is in the form of a particulate dispersion of cationic fabric softener in an aqueous solution of alkoxylated amine or ammonium derivative thereof; said composition being free of hydrocarbon and fatty acid ester nonionic fabric softeners.
Claim 4
Dependent Claim 192 words
An aqueous textile treatment composition comprising (a) from 13.5% to 20% of substantially water-insoluble cationic fabric softener, said cationic softener being selected from the group consisting of di-C 12 -C 24 alkyl and alkenyl quaternary ammonium salts, di-C 12 -C 24 alkyl and alkenyl imidazolinium salts and mixtures thereof, (b) from 0.3% to 2.5% of an alkoxylated amine, or ammonium derivative thereof, of the general formula: ##STR9## wherein R 1 is a C 16 -C 22 alkyl or alkenyl group, n is 2 and x and y are each a number average in the range from about 1 to 11, the sum total of x and y being 1 to 12, (c) from 600 to 1000 parts per million of electrolyte, and (d) from 0.1% to 5% of a polyethyleneglycol having an average molecular weight in the range from 1000 to 40,000, wherein the composition has a pH in the range from 3.5 to 7.0 and is in the form of a particulate dispersion of cationic fabric softener in an aqueous solution of alkoxylated amine or ammonium derivative thereof; said composition being free of hydrocarbon and fatty acid ester nonionic fabric softeners.
