Abstract

The present invention is directed to liquid laundry compositions which deliver both effective softening and effective cleaning containing a solubilised cationic polymer and a solubilised soap blend which incorporates a saturated hydroxyl carboxylic acid. A method of cleaning and conditioning articles using the inventive compositions is also disclosed.

Claims

1. A liquid laundry composition comprising:

(d) a solubilized cationic polymer having a weight average molecular weight of less than about 850,000 daltons;

(e) from about 0.5% to about 15% of a solubilized fatty acid soap blend comprising from about 5% to about 60%, by weight of the soap blend, of a saturated hydroxy carboxylic acid salt R²CH₂CH₂OOM, wherein R² is a saturated hydroxyalkyl group comprising from 7 to 21 carbons and one hydroxy group;

(f) at least about 5% of a surfactant.

2. The composition according to claim 1, wherein the level of cationic polymer is less than about 3%.

3. The composition according to claim 1, wherein R2 comprises from 9 to 17 carbon atoms.

4. The composition according to claim 1 wherein the saturated hydroxy carboxylic acid salt is 12-hydroxystearic acid salt.

5. The composition according to claim 1, wherein the composition is an isotropic liquid.

6. The composition of claim 1 wherein the pH of the composition is from about 7 to about 9.

7. The composition according to claim 1, wherein at least one cationic polymer is selected from the group consisting of dimethyl diallyl ammonium chloride/acrylamide copolymers, dimethyl diallyl ammonium chloride/acrylic acid/acrylamide terpolymers, vinylpyrrolidone/methyl vinyl imidazolium chloride copolymers, polydimethyl diallyl ammonium chloride, starch hydroxypropyl trimmonium chloride, polymethacryl amidopropyl trimethyl ammonium chloride, acrylamidopropyl trimmonium chloride/acrylamide copolymers, guar hydroxypropyl trimonium chloride, and hydroxyethyl cellulose derivatized with trimethyl ammonium substituted epoxide.

8. The composition of claim 1 wherein the soap blend is present in an amount of from 3 to 10%.

9. The composition of claim 1 wherein the saturated hydroxylcarboxylic acid is present in an amount of from 5 to 40%, by weight of the soap blend.

10. The composition according to claim 1, wherein the weight ratio of the cationic polymer to the soap blend in the composition is in the range of from 1:

10 to 1;

50.

11. The composition according to claim 1, wherein the weight ratio of the cationic polymer to the soap blend in the composition is in the range of from 1:

20 to 1;

35.

12. A method for conditioning textiles comprising, in no particular order, the steps of:

a) providing a laundry composition according to claim 1, in an effective amount to soften and condition fabric articles under predetermined laundering conditions

b) contacting one or more articles with said composition at one or more points during a laundering process

c) allowing the article or articles to dry or mechanically tumble-drying them.

13. The method according to claim 12, wherein at least one cationic polymer in said laundry composition is selected from the group consisting of dimethyl diallyl ammonium chloride/acrylamide copolymers, dimethyl diallyl ammonium chloride/acrylic acidlacrylamide terpolymers, vinylpyrrolidone/methyl vinyl imidazolium chloride copolymers, polydimethyl diallyl ammonium chloride, starch hydroxypropyl trimmonium chloride, polymethacryl amidopropyl trimethyl ammonium chloride, acrylamidopropyl trimmonium chloride/acrylamide copolymers, guar hydroxypropyl trimonium chloride, and hydroxyethyl cellulose derivatized with trimethyl ammonium substituted epoxide.
