Disclosed are oligoesters including residues of alk(en)yl succinic anhydrides and polyols having at least three 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 C8 to C30 alk(en)yl succinic anhydride and polyols having at least 4 hydroxyl groups and are particularly of the formula (I): R1—[OR2O(O)C.C(HR3).(HR4)C.C(O)]m—R5 (I), where R1, R2, R3, R4, R5, R6, R7 and m have defined meanings. The surfactants are useful as emulsifiers, particularly o/w emulsifiers.
