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.
Claims8
A cleaning composition with a surfactant package comprising:
- an extended chain nonionic surfactant comprising a C10 or C12-[PO]8-[EO]y guerbet alcohol, wherein y is the average degree of ethoxylation ranging from 3 to 10;
- an additional surfactant having an EO/PO block copolymer, wherein the ratio of extended chain nonionic surfactant to EO/PO block copolymer is about 5:1,
- wherein no other extended chain nonionic surfactants are present, and
- wherein the composition is free of an alkalinity source.
