Abstract
Abstract An emulsifying and peptizing agent having the formula RO[C.sub.2 H.sub.3 O(R')].sub.m [C.sub.2 H.sub.3 O(X)].sub.n II wherein R is a lipophilic hydrocarbon residue of a member selected from the group consisting of alcohols, sterols and their mixtures derived from a member selected from the group consisting of (a) hydrogenated lanolin, and (b) cyclic fatty acids, R' is selected from the group consisting of methyl and ethyl, X is selected from the group consisting of --CH 2 OH, ##STR1## m has a statistical average value between 1-10 inclusive, N HAS A STATISTICAL AVERAGE VALUE BETWEEN 1-5 INCLUSIVE, p is an integer between 0-10 inclusive and the product n(p+2) lies between 2-12 inclusive.
