Patent number: 5866525Abstract: A particulate laundry detergent composition is provided having significantly improved oily soil removal activity. The composition comprises (a) from about 1 to 50%, by weight, of one or more detergent compounds selected from the group consisting of anionic and nonionic detergent compounds, and particularly alkyl polyglucoside and poly hydroxy fatty acid amide detergents; (b) a lipase enzyme in an amount effective for oily soil removal from stained fabric; and (c) a soil release polymer in an amount effective for oily soil removal from stained fabric. The laundry detergent compositions is characterized by its ability to remove a variety of oily soils from fabric to an extent greater than the additive soil removing effects measured with comparative compositions containing components (a) and (b), and components (a) and (c), respectively.Type: GrantFiled: June 6, 1996Date of Patent: February 2, 1999Assignee: Colgate-Palmolive CompanyInventors: Charles Andrew Beagle, Elliot Michael Scherr, Riad Ahned Taha, Joseph Robert Knorr
