Polyurethane redeposition inhibiting polymers and detergent compositions containing same

A detergent composition comprising:

• a) from about 1 to about 99 wt % of 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, wherein said polyurethane polymer is prepared by reacting together:
• (i) one or more polyisocyanates having an average functionality of from about 2 to about 2.5;
• (ii) one or more compounds having at least one poly(C2-C4 alkylene oxide) chain and at least two groups which react with isocyanate groups and are located at one end of said compound such that the poly(C2-C4 alkylene oxide) chain is laterally disposed relative to the polyurethane polymer backbone;
• (iii) one or more compounds containing at least one acid group and at least two groups which react with isocyanate groups;
• (iv) optionally, one or more chain extending compounds having a number average molecular weight of from about 32 to about 3000 g/mole containing at least two groups which react with isocyanate groups;
• and
• (v) optionally, one or more chain terminator compounds containing one group which reacts with isocyanate groups;
• wherein the polyurethane has an acid value ranging from about 1 to about 300 mg of KOH/g;
• and wherein said detergent composition is a form selected from the group consisting of a granular detergent, a liquid laundry detergent, a gel detergent, a unit dose detergent, a detergent contained in water soluble pouch, a liquid hand dishwashing detergent, a laundry pre-treat product, an automatic dish washing detergent, and a hard surface cleaner.
