Abstract

Compounds of the following formula are suitable for reducing the interfacial surface tension of oily phases with respect to water: <IMAGE> wherein z is 1 or 2, R, for z=1, is alkyl, aralkyl, or alkylaryl of 8-22 carbon atoms in the alkyl chain, or hydroxyalkyl of 2-22 carbon atoms, and, for z=2, is (aryl)alkylene of 4-18 carbon atoms, R' and R'' each independently is hydrogen or C1-C20-alkyl wherein R' and R'' are not simultaneously hydrogen and R' and R'' together have 8-20 total carbon atoms, x is 10-40 and y is 1.2-5.
