ABSTRACT:
Highly stable emulsions of carboxyl-containing silicone fluids in water are prepared by using a combination of two surfactants. The first, or primary surfactant, has the formula RO(C.sub.m H.sub.2m O).sub.n H, where R is a hydrocarbon lipophile, m has a value of 1, 2, or 3, and n has an average value greater than 15. The second or cosurfactant, is selected from fatty acid esters of sorbitol and surfactants having the formula R'O(C.sub.p H.sub.2p O).sub.q H, wherein R' is a hydrocarbon lipophile, p has a value of 1, 2, or 3 and q has a value such that the cosurfactant is just insoluble in the carboxyl-containing silicone fluid.
