Abstract:
A detergent compositions comprising:a) from about 4% to about 70% by weight, of a surfactant; b) from about 0.01% to about 10% by weight, of a dye maintenance co-polymer, said copolymer having the general formula: â€ƒx has the value of from about 10 to about 100,000; y has the value of from about 10 to about 100,000; the ratio of x to y is from 9:1 to 1:9; each Z is independently a heterocycling ring containing an N-oxide, a cationically charged heteroaromatic monomer, a cyclically polymerizing monomer, or (CH2)mCORâ€², wherein Râ€² is selected from: i) â€”OR3; ii) â€”O(CH2)nN(R3)2; iii) â€”O(CH2)nN+(R3)3Xâˆ’; iv) â€”NR3(CH2)nN(R3)2; v) â€”NR3(CH2)nN+(R3)3Xâˆ’; vi) â€”(CH2)nN(R3)2; vii) â€”(CH2)nN+(R3)3Xâˆ’; viii) or mixtures thereof; each R3 is independently hydrogen, C1-C8 alkyl, C2-C8 hydroxyalkyl, and mixtures thereof; X is a water soluble anion; the index n is from 0 to 6; the index m is from 0 to 6; provided said polymer or co-polymer has a net cationic charge; and wherein said dye maintenance polymer is not an polyethyleneimine or alkoxylated derivative thereof; and c) the balance carriers and other adjunct ingredients.
