Patent ID: 8450261

Claim:
A laundry detergent or cleaning composition which comprises a copolymer composition comprising: i) a copolymer having a weight-average molecular weight of from about 12,000 to about 20,000 and comprising: a) 30-60 mol% structural units derived from monoethylenically unsaturated dicarboxylic acid (salt); b) structural units derived from monoethylenically unsaturated monocarboxylic acid (salt); c) structural units derived from monomers containing sulfonic acid (salt) groups and having no ester bonds or amido bonds, wherein the molar ratio of (a)/(b)/(c) is from about 30 to about 60/from about 30 to about 60/and from about 5 to about 16 where the sum of the molecular weight percent is 100%; and ii) 7,000 ppm or less of residual monoethylenically unsaturated dicarboxylic acid (salt) monomer; and wherein the laundry detergent composition further comprises from about 1% to about 4% by weight of the composition of a non-ionic surfactant, wherein the non-ionic surfactant is a C 12 -C 18 alkyl ethoxylate; and wherein the laundry detergent composition comprises a chelant builder selected from the group consisting of methyl glycine diacetic acid, salts of methyl glycine diacetic acid and mixtures thereof.
