Compositions and methods for providing a benefit

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

• a. optionally, washing a fabric;
• b. combining a fabric care additive composition comprising a cationic polymer with a source of anionic surfactant to form a mixture having an ACD:CCD ratio of from about 7:1 to about 0.1:1,
• 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,
• wherein said cationic polymer comprises a cationic monomer selected from N,N-dialkylaminoalkyl acrylate, quaternized N,N-dialkylaminoalkyl acrylate, N,N-dialkylaminoalkyl methacrylate, quaternized N,N-dialkylaminoalkyl methacrylate, diallyl dialkyl ammonium chloride, and combinations thereof,
• and wherein said cationic polymer further comprises a second monomer selected from the group consisting of acrylamide, methacrylamide, vinyl formamide, acrylic acid, and combinations thereof;
• c. contacting said mixture with said fabric to form a treated fabric;
• d. optionally, rinsing said treated fabric.
