Laundry detergent compositions containing lipase and soil release polymer

A particulate laundry detergent composition having significantly improved oily soil removal activity comprising, by weight, (a) from about 1% to 50% of one or more detergent compounds selected from the group consisting of anionic sulfated or sulfonated detergents and C10-C18 alcohol ethylene oxide condensate nonionic detergents and mixtures thereof;

• (b) 0.1% to 1.0% of a lipase enzyme in an amount effective for oily soil removal from stained fabric;
• (c) 0.5% to 10% of a soil release copolymer of polyethylene terephthalate (PET) and polyoxyethylene terephthalate (POET) having a molecular weight in the range of about 15,000 to 50,000 wherein the polyoxyethylene (POET) is of a molecular weight in the range of about 1,000 to 10,000 and the molar ratio of PET to POET units is from 2:1 to 6:1, in an amount effective for oily soil removal from stained fabric;
• and (d) from about 10% to 75% of a water soluble or water insoluble, inorganic or organic builder for said detergent compound;
• said laundry detergent composition being capable of removing a variety of oily soils from fabric to an extent greater than the additive soil removing effects measured with comparative compositions containing components (a), (b) and (d) or (a), (c) and (d) respectively, each of said comparative compositions being devoid of any combination of said lipase enzyme and said soil release copolymer.
