Abstract
The present technology relates to polymeric additives and their incorporation into cleaning compositions useful in household detergents and other related uses including, dishwash (institutional and consumer), hard surface cleaners and textile care. The disclosed cleaning compositions include a detersive agent and a soil redeposition inhibiting agent. In one aspect, the soil redeposition inhibiting agent is selected from a functionalized polyurethane polymer.
Claims43
A detergent composition comprising:
- a) at least one surfactant;
- and
- b) a polyurethane anti-redeposition polymer comprising from about 35 to 90 wt. % of a poly(C2-C4 alkylene oxide) based on the total weight of the polyurethane polymer, wherein not less than at least 5 wt. % of the poly(C2-C4 alkylene oxide) is poly(ethylene oxide), and wherein at least 5 wt. % of the poly(C2-C4 alkylene oxide) based on the total weight of the polyurethane polymer is incorporated in lateral chains pending from the polyurethane polymer, and wherein the polyurethane has an acid value ranging from about 1 to about 300 mg of KOH/g, or from about 5 to about 200 mg of KOH/g, or from about 10 to about 150 mg of KOH/g.
