Abstract

The present invention relates to fabric enhancer compositions as well as the methods of making and using same. Such fabric enhancer compositions comprise a quaternary ammonium ester fabric softening active, a branched, ethoxylated nonionic surfactant and perfume. Such fabric enhancer compositions exhibit improved freeze-thaw stability while also delivering the softening benefits that are desired by consumers.

First claim

What is claimed is:

1. A fabric enhancer composition having a viscosity of from 20 cP to 700 cP and a pH of from about 1 to about 5 said fabric enhancer composition comprising, based on total composition weight:
a) from about 3% to about 20% of a quaternary ammonium ester fabric softening active, said quaternary ammonium ester fabric softening active comprising isomers of bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;
b) from about 0.01% to about 30% of an alcohol comprising from 1 to 7 carbons, said alcohol comprising glycerol; and
c) from about 0.1% to about 10% of a perfume delivery system and/or from about 0.1% to about 4% perfume;
d) a nonionic surfactant having Formula A:

wherein n is on average from about 30 to 85, R 1 is hydrogen or an alkyl group comprising from 1 to 21 carbons; R 2 is an alkyl chain comprising from 1 to 22 carbon atoms, with the proviso that the sum of the total number of carbon atoms of R 1 and R 2 is from 9 to 22;
the ratio of quaternary ammonium ester softener active to nonionic surfactant being 1:1 to 7:1.

2. A fabric enhancer composition according to claim 1 wherein said quaternary ammonium ester fabric softening active further comprises a member selected from the group consisting of:
a) bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;
b) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium chloride fatty acid ester;
c) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium methylsulfate fatty acid ester; and
d) N,N,N-tri(2-hydroxyethyl)-N-methyl ammonium methylsulfate fatty acid ester;
said quaternary ammonium ester fabric softening active comprising a fatty acid ester moiety having 12 to 22 carbons and being saturated or unsaturated, and substituted or unsubstituted.

3. A fabric enhancer composition according to claim 1 wherein a parent fatty acid moiety of said quaternary ammonium ester fabric softening active is:
a) saturated, substituted and of animal origin;
b) saturated, substituted and of vegetable origin;
c) saturated, unsubstituted and of animal origin;
d) saturated, unsubstituted and of vegetable origin;
e) unsaturated, substituted and of animal origin;
f) unsaturated, substituted and of vegetable origin;
g) unsaturated, unsubstituted and of animal origin; or
h) unsaturated, unsubstituted and of vegetable origin.

4. A fabric enhancer composition according to claim 3 , wherein said quaternary ammonium ester fabric softening active has an iodine value from 0 to about 60.

5. A fabric enhancer composition according to claim 1 , wherein said perfume delivery system is selected from the group consisting of benefit agent delivery particles, pro-perfumes, polymer particles, functionalized silicones, polymer assisted delivery, molecule assisted delivery, fiber assisted delivery, amine assisted delivery, cyclodextrins, starch encapsulated accord, zeolite and inorganic carrier, and mixtures thereof.

6. A fabric enhancer composition according to claim 5 , wherein said perfume delivery system comprises benefit agent containing delivery particles.

7. A fabric enhancer composition according to claim 6 , wherein said perfume delivery system comprises two or more types of benefit agent containing delivery particles.

8. A fabric enhancer composition according to claim 1 comprising an adjunct material.

9. A fabric enhancer composition according to claim 1 , said fabric enhancer composition having a viscosity of from 60 cP to 400 cP and a pH of from about 2 to about 4, said fabric enhancer composition comprising, based on total composition weight:
a) from about 6% to about 12% of said quaternary ammonium ester fabric softening active;
b) from about 2% to about 9% of said alcohol; and
c) from about 0.1% to about 10% of a perfume delivery system and/or from about 0.1% to about 4% perfume;
d) a nonionic surfactant having Formula A:

wherein n is on average from about 30 to 45; R 1 is an alkyl group comprising from 1 to 21 carbons; R 2 is an alkyl chain comprising from 1 to 22 carbon atoms, with the proviso that the sum of the total number of carbon atoms of R 1 and R 2 is from 9 to 22;
the ratio of quaternary ammonium ester softener active to nonionic surfactant being 2:1 to 13:2; and
said fabric enhancer composition comprising, from 1.2% to about 2% of said nonionic surfactant.

10. A fabric enhancer composition according to claim 9 wherein said quaternary ammonium ester fabric softening active further comprises a member selected from the group consisting of:
a) bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;
b) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium chloride fatty acid ester;
c) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium methylsulfate fatty acid ester; and
d) N,N,N-tri(2-hydroxyethyl)-N-methyl ammonium methylsulfate fatty acid ester;
said quaternary ammonium ester fabric softening active comprising a fatty acid ester moiety having 12 to 22 carbons and being saturated or unsaturated, and substituted or unsubstituted.

11. A fabric enhancer composition according to claim 9 wherein the parent fatty acid moiety of said quaternary ammonium ester fabric softening active is:
a) saturated, substituted and of animal origin;
b) saturated, substituted and of vegetable origin;
c) saturated, unsubstituted and of animal origin;
d) saturated, unsubstituted and of vegetable origin;
e) unsaturated, substituted and of animal origin;
f) unsaturated, substituted and of vegetable origin;
g) unsaturated, unsubstituted and of animal origin; or
h) unsaturated, unsubstituted and of vegetable origin.

12. A fabric enhancer composition according to claim 9 , wherein said perfume delivery system comprises two or more types of benefit agent containing delivery particles.

13. A fabric enhancer composition according to claim 9 comprising an adjunct material.

14. A fabric enhancer composition according to claim 1 , wherein said fabric enhancer composition comprises, based on total composition weight, from 1.1% to about 5% of said nonionic surfactant.

15. A method of treating and/or cleaning a fabric, said method comprising
a) optionally washing, rinsing and/or drying said fabric;
b) contacting said fabric with a fabric enhancer composition according to claim 1 and
c) optionally washing, rinsing and/or drying said fabric wherein said drying steps comprise active drying and/or passive drying.
