Abstract

Disclosed herein are detergent compositions containing extended chain surfactants that form microemulsions with and can remove greasy and oily stains. In certain embodiments the extended nonionic surfactant includes Guerbet C10 or C12(PO)8(EO)n. The detergent compositions and methods of employing the same beneficially clean soils from textiles including difficult to remove cosmetic soils and food oils, even those comprised of non-trans fats.
