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

1-7. -7. (canceled)

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

a. optionally, washing a fabric;

b. combining a composition comprising, based on total composition weight, from about 5% to about 20% of a cationic polymer, wherein said cationic polymer has 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 and 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, 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;

optionally, rinsing said treated fabric.

9. A method according to claim 8, 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.

10. A method according to claim 8 wherein the contacting step is carried out at a temperature of from about 50°

C. to about 75°

C.

11. A method according to claim 8 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 −

0.01 to about −

15.

12. A method according to claim 8 wherein the source of anionic surfactant comprises, based on total source of anionic surfactant weight, from about 2% to about 50% anionic surfactant.

13. A method according to claim 8 wherein the source of anionic surfactant comprises, based on total source of anionic surfactant weight, from about 1.0% to about 50% of alkylethoxysulfonate.

14. A method according to claim 8 wherein the source of anionic surfactant comprises, based on total source of anionic surfactant weight, less than about 5% linear alkylbenzene sulfonate.

15. A method according to claim 8 wherein the source of anionic surfactant comprises, based on total source of anionic surfactant weight, less than about 10% nonionic surfactant.

16. A method according to claim 8, wherein the source of anionic surfactant comprises the fabric to be treated.

17. A method according to claim 8, wherein the ppm of the cationic polymer in the mixture is from about 1 to about 5,000.

18. A method according to claim 8, wherein the cationic charge density ratio of said composition to said source of anionic surfactant is about 0.79:

1.

19. A method according to claim 8, wherein said method is carried out as a service to a consumer.
