Abstract
The disclosed technology relates to compositions useful as detergents in cleaning a wide variety of substrates, including laundry, hard surfaces and dish. The compositions contain a functionalized polymer which is prepared by reacting: i) a styrene/maleic anhydride copolymer and ii) a poly(oxyalkylene) monoamine. Compositions according to the disclosed technology have good cleaning performance and beneficial anti-redeposition properties.
Claims8
A method for imparting anti-redeposition properties to a laundry detergent composition by adding from about 0.25 to about 2 wt. % (based on the total weight of the composition) of a functionalized polymer to said detergent, wherein said laundry detergent composition comprises at least one surfactant, and wherein said functionalized polymer is prepared by reacting:
- i) a styrene maleic anhydride copolymer;
- ii) a poly(oxyalkylene) monoamine;
- and optionally
- iii) a poly(oxyalkylene) diol;
- wherein said styrene maleic anhydride copolymer (i) has a styrene:
- maleic anhydride mole ratio of 2:1.
