Abstract

Compositions and methods useful for providing one or more benefits, including a color rejuvenation and/or color maintenance benefit to a fabric are disclosed. The disclosed compositions contain at least one cationic polymer. The methods include providing the disclosed compositions in combination with a source of anionic surfactant. Unit dose and multi-compartment systems are also disclosed.

Claims

1. A composition comprising, based on total composition weight, from about 0.1% to about 100% of a cationic polymer, said cationic polymer having a charge density of from about 0.05 meq/g to about 25 meq/g at a pH of from about 2 to about 11.

2. A composition according to claim 1 wherein said cationic polymer comprises a polymer selected from the group consisting of alkylamine epichlorohydrin polymers, homopolymers of diallyldimethyl ammonium chloride, copolymers of diallyldimethyl ammonium chloride, and combinations thereof.

3. A composition according to claim 1 wherein the cationic polymer comprises poly(diallyldimethylammonium chloride-co-acrylic acid).

4. A composition according to claim 1 wherein said cationic polymer has a weight-average molecular weight of from about 500 to about 5,000,000 Daltons.

5. A composition according to claim 1, wherein said composition comprises an organosilicone.

6. A composition according to claim 1, said composition having, under wash conditions, a particle size of from about 0.005 to about 1000 μ

m.

7. A composition according to claim 1, wherein said composition under wash conditions, comprises a coacervate having an elastic and viscous modulus of from about 10 to about 1,000,000 Pa as measured using the Test Methods.

8. A method of delivering a benefit to a fabric comprising the steps of

a. optionally, washing a fabric;

b. combining the composition of claim 1 with a source of anionic surfactant to form a mixture having an ACD;

CCD ratio of from about from about 100;

1 to about 0.01;

1;

c. contacting said mixture with said fabric to form a treated fabric;

d. optionally, rinsing said treated fabric.

20. A unit dose system wherein said composition of claim 1 is enclosed in a water miscible pouch, wherein said composition comprises, based on total weight of the composition, less than about 15% water.

21. A multi-compartment system comprising a first and second compartment, wherein said first compartment comprises a composition according to claim 1, and wherein said second compartment comprises a source of anionic surfactant.

10. A method according to claim 10 wherein the contacting step is carried out at a temperature of from about 50°

C. to about 75°

C.

9. A method according to claim 10, comprising the step of applying one or more finishing treatments to the treated fabric selected from the group consisting of drying, pressing, starching, perfuming, and combinations thereof.

11. A method according to claim 10 wherein said benefit comprises a color maintenance and/or rejuvenation benefit, wherein said treated fabric, as measured when dry, has a Δ

L value of from about −
