Abstract:
1. A laundry detergent composition comprising from about 10% to about 90% water and having a pH of from about 6 to about 11, wherein the composition further comprises: iii) from about 0.05% to about 2%, by weight of the composition, of a polymer having a number average molecular weight of from 700,000 to 4,000,000 and comprising monomeric units, wherein the monomeric units are derived from monomers, said monomers comprising: i) at least 70%, by mole, of acrylamide; ii) from about 3% to about 30%, by mole, of [(3-methylacrylamido) propyl] trimethylammonium chloride; iii) from about 1% to about 20%, by mole, of acrylic acid; and iv) optionally from 0% to about 10%, by mole, of methacrylic acid; wherein the mole ratio of the monomers, according to the following equation, is from 0.3 to 0.8; b) from about 5% to about 60%, by weight of the composition, of a surfactant system comprising from about 3% to about 15% fatty acid; and c) at least 0.1%, by weight of the composition, of an electrolyte.
