Patent ID: 7241729

Claim:
A method for providing increased suds volume and increased suds retention while washing a fabric and/or garment in need of cleaning, comprising the step of contacting said fabric and/or garment with an aqueous solution of a laundry detergent composition, said laundry detergent composition comprising: a) an effective amount of a polymeric suds stabilizer, said stabilizer comprising: i) units capable of having a cationic charge at a pH of from about 4 to about 12; provided that said suds stabilizer has an average cationic charge density from about 0.05 to about 5 units per 100 daltons molecular weight at a pH of from about 4 to about 12, and ii) a monomeric unit having no charge at a pH of from about 4 to about 12, wherein said polymeric suds stabilizer (a) is a copolymer of: b) an effective amount of a detersive surfactant; and c) the balance carriers and other adjunct ingredients; provided that the pH of a 10% aqueous solution of said laundry detergent composition is from about 4 to about 12; wherein the mole ratio of i to ii ranges from 2 to 10:1.
