Abstract:
1. A method of delivering a color maintenance and/or rejuvenation benefit to a fabric comprising the steps of: a. washing a fabric; b. combining a fabric care additive composition having an acidic pH comprising, based on total composition weight, from about 5% to about 20% of a cationic polymer, said fabric care additive composition further comprising a cationic surfactant, 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 is a polymer selected from the group consisting of alkylamine epichlorohydrin polymers, homopolymers of diallyldimethyl ammonium chloride, copolymers of diallyldimethyl ammonium chloride, and combinations thereof, in the presence of water in a washing machine with a conventional detergent as a source of anionic surfactant to form a mixture having an ACD:CCD ratio of from about 2:1 to about 0.1:1; c. contacting said mixture with said fabric to form a treated fabric; d. rinsing said treated fabric; e. applying one or more finishing treatments selected from the group consisting of drying, pressing, starching, perfuming, and combinations thereof to the treated fabric wherein said method is carried out as a service to a consumer.
