Abstract
Oligoesters including residues of alk(en)yl succinic anhydrides and polyols having at least 3 OH groups, optionally further esterified with fatty acid residues are surfactants which can be used for emulsifiers or similar uses. The surfactants are usually made from Cto Calk(en)yl succinic anhydride and polyols having at least 4 hydroxyl groups and are particularly of the formula (I): R—[ORO(O)C.C(HR).(HR)C.C(O)]—R(I), where R, R, R, R, R, R, Rand m have defined meanings. The surfactants are useful as emulsifiers, particularly oil in water emulsifiers.
