Abstract
The present invention relates to novel fabric care compositions water containing dispersible or water-soluble copolymers which contain at least one UV-absorbing monomer and one hydrophilic monomer component.
Claims20
A heavy duty detergent composition comprising:
- (a) about 20 to about 75% by weight of a surfactant selected from the group consisting of soap, nonionic surfactant, anionic surfactant, ampholytic surfactant, zwitterionic surfactant, cationic surfactant and mixtures thereof;
- and
- (b) about 0.01 to 10% by weight of a water-soluble or water-dispersible copolymer comprising a UV-absorbing monomer (absorbing in the 280-400 monomer range) and a hydrophilic group;
- wherein said copolymer has the formula:
- ##STR5## wherein R is a difunctional aryl group or a difunctional straight or branched alkyl chain having 4 to 16 carbons;
- R.sub.1 is hydrogen, an aliphatic group having 1-20 carbons, an aryl, alkaryl, a secondary amine, an alkali metal sulfonate, an alkali metal carboxylate, an alkyl ether or a halogen atom;
- R.sub.2 is a straight or branch chain alkoxy group having 1 to 16 carbons, an aryl or a substituted aryl group;
- R.sub.3 is a straight or branch chain alkyl group having 1 to 16 carbons;
- R.sub.4 is a UV-absorbing monomer absorbing in the UVB (280-320 nm) and/or UVA (320-400 nm) range;
- x is selected such that the hydrophobe is present at 0-49.9 mol % of the polymer;
- y is selected such that the R.sub.2 group is present at 0-49.9 mol % of the polymer;
- z is selected such that the (OR.sub.3).sub.n group is present at 0 to 49.9 mol % of the polymer wherein n is an integer between about 12 and 200;
- w is selected such that R.sub.4 is present at 0.05 to 99.9 mol % of the polymer;
- and w plus z equal at least 0.05 to 99.9 mol % of the polymer;
- and w plus z equal at least 0.05 mol %.
