Abstract

Liquid fabric treatment compositions that include benefit agent capsules, brightener, and a quaternary ammonium ester softening active. Methods of making and using such compositions.

First claim

What is claimed is:

1. A liquid fabric treatment composition comprising by weight of the composition of:
a) about 0.1 to about 200 ppm of benefit agent capsules wherein the benefit agent capsules comprise a shell material encapsulating a core material, wherein said shell material is derived from polyvinylalcohol and a shell component wherein said shell component is polyacrylate; said core material comprises perfume raw materials, wherein the perfume raw materials are present in an amount of from 20% to 98% by weight of the benefit agent capsules;
b) about 0.1 to about 50 ppm of a brightener wherein said brightener is

and
c) about 10 to about 2000 ppm of a quaternary ammonium ester softening active.

2. The liquid fabric treatment composition according to claim 1 wherein the level of polyvinylalcohol is from about 0.01 to about 20% by weight of the benefit agent capsules.

3. The liquid fabric treatment composition according to claim 1 wherein the level of brightener is from about 0.5 to about 30 ppm by weight of the fabric treatment composition.

4. The liquid fabric treatment composition according to claim 1 wherein the polyvinylalcohol has a degree of hydrolysis of about 70% to about 99%.

5. The liquid fabric treatment composition according to claim 1 wherein the polyvinylalcohol as a 4 wt % solution in water has a viscosity of from about 2 mPa·s to about 150 mPa·s.

6. The liquid fabric treatment composition according to claim 1 wherein the weight ratio of polyvinylalcohol to brightener is from about 1/1 to about 1/5000.

7. The liquid fabric treatment composition according to claim 1 wherein the ratio of brightener to benefit agent capsules is from about 50/1 to about 1/500.

8. The liquid fabric treatment composition according to claim 1 wherein said quaternary ammonium ester softening active has the following formula:
{ R 2 (4-m) —N +—[ X—Y—R 1 ] m }A—

wherein:
m is 1, 2 or 3 with proviso that the value of each m is identical;
each R 1 is independently hydrocarbyl, or substituted hydrocarbyl group;
each R 2 is independently a C 1 -C 3 alkyl or hydroxyalkyl group;
each X is independently (CH 2 )n, CH 2 —CH(CH 3 )— or CH—(CH 3 )—CH 2 — and
each n is independently 1, 2, 3 or 4;
each Y is independently —O—(0)C— or —C(O)—O—;
A- is independently selected from the group consisting of chloride,
methylsulfate, ethylsulfate, and sulfate; with the proviso that the sum of carbons in each R 1 , when Y is —O—(0)C—, is from about 11 to about 21.

9. The liquid fabric treatment composition according to claim 1 wherein said quaternary ammonium ester softening active comprises a fatty acid moiety comprising about 12 to about 22 carbons, said quaternary ammonium esters being selected from the group consisting of:
a) bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;
b) isomers of bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;
c) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium chloride fatty acid ester;
d) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium methylsulfate fatty acid ester; and
e) N,N,N-tri(2-hydroxyethyl)-N-methyl ammonium methylsulfate fatty acid ester;
said quaternary ammonium ester softening active's fatty acid ester moiety being saturated or unsaturated, and substituted or unsubstituted.

10. A method for making a liquid fabric treatment composition according to claim 1 comprising the following steps:
a. providing a composition comprising a brightener which is

b. mixing the composition comprising the brightener of step a) with an aqueous solution to form a dilute composition comprising the brightener;
c. providing a composition comprising the quaternary ammonium ester softening active and the benefit agent capsules;
d. mixing the composition comprising the quaternary ammonium ester softening active of step c) with the dilute composition comprising the brightener of step b) to form a liquid fabric treatment composition according to claim 1 .
