Abstract:
1. 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) 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.
