SURFACTANT COMPOUNDS

摘要

Oligoesters including residues of alk(en)y! 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 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, particuarly oil in water emulsifiers.
