Abstract
The invention discloses synergistic combinations of surfactant blends and cleaning compositions employing the same. In certain embodiments a surfactant system is disclosed which includes an extended anionic surfactant with novel co-surfactants including one or more of an alkyl glycerol ether, an ethoxylated alkyl glycerol ether, an alcohol ethoxylate and/or a gemini surfactant. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.
Claims10
A laundry detergent composition comprising:
- a builder;
- an enzyme;
- and
- a surfactant system comprising an extended chain C12-C14 alkyl anionic sulfate surfactant having 5 or more moles of propoxylation;
- one or more amine co-surfactants comprising:
- an alkyl oxypropyl diamine, wherein the amine co-surfactant has a branched isodecyl or isotridecyl group;
- and
- an extended nonionic ethoxylated or ethoxylated and propoxylated C8-C11 alcohol surfactant having from 1 to 10 moles of ethoxylation,
- wherein the extended chain C12-C14 alkyl anionic sulfate surfactant and the amine co-surfactant and the extended nonionic ethoxylated or ethoxylated and propoxylated C8-C11 alcohol surfactant have a weight ratio of 1.67:1:0.75,
- wherein said surfactant system forms an emulsion or microemulsion with an oily soil when the amine co-surfactant is neutral and precipitates with oily soil when the amine co-surfactant is protonated.
