Abstract

Compounds of the following formula are suitable for reducing the interfacial surface tension of oily phases with respect to water: ##STR1## wherein z is 1 or 2, PA1 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, PA1 R' and R" each independently is hydrogen or C.sub.1 -C.sub.20 -alkyl wherein R' and R" are not simultaneously hydrogen and R' and R" together have 8-20 total carbon atoms, PA1 x is 10-40 and PA1 y is 1.2-5.
