Abstract

Synergistic combinations of extended chain surfactants and co-surfactants, emulsions or microemulsions and cleaning compositions incorporating the same are provided. In certain embodiments a surfactant system is disclosed which includes extended nonionic surfactants, and a linker surfactant. This system forms stable emulsions or microemulsions with oils, including non-trans fats and fatty acids and these emulsions or microemulsions are stable, irreversible and can be created at low temperature. The cleaning compositions may include the surfactant system alone, a stable emulsion or microemulsion with oil and the surfactant system, a pre-spotter or other pre-treatment or soft surface and hard surface cleaning compositions comprising the surfactant combination.

Dependent claims

A surfactant system for forming stable emulsions or microemulsions with oils comprising:

an extended chain nonionic surfactant having an intermediate polarity linking chain between a lipophilic segment and a hydrophilic segment of said surfactant, wherein said linking chain is selected from the group consisting of (PO)x,(EO)x,(PO)x(EO)xand combinations thereof, wherein x is from 1 to 16;
and
a linker co-surfactant selected from the group consisting of:
monoglycerides, diglycerides, fatty acids, fatty di acids and combinations thereof;
wherein the ratio of said extended chain nonionic surfactant and linker co-surfactant is from about 7:1 to about 2:1 on a weight percentage ratio basis, and wherein the system forms an emulsion or microemulsion with oils that is stable and irreversible at temperatures between 60° C. and 100° C.
