Abstract
Abstract This invention relates to a combination of anionic and/or nonionic surface-active compounds together with a foam stabilizer and a foam inhibitor active at temperatures above 60* C, said combination having controlled foaming properties, containing therein as foam stabilizer active at temperatures up to 60* C, a compound of the formula selected from the group consisting of WHEREIN R-CO represents the acyl of a fatty acid with 10 to 18 carbon atoms, R1 represents an aliphatic hydrocarbon radical with 10 to 18 carbon atoms, R2 represents an alkylene group with two to five carbon atoms, R3 and R4 represent members selected from the group consisting of hydroxyethyl, hydroxypropyl and dihydroxypropyl, R5 and R6 represent members selected from the group consisting of methyl, ethyl, hydroxyethyl, hydroxypropyl and dihydroxypropyl, R7 represents members selected from the group consisting of hydrogen, methyl, ethyl, hydroxyethyl, hydroxypropyl and dihydroxypropyl, n is an integer from 1 to 2 and Me represents a member selected from the group consisting of hydrogen and alkali metal. The invention also relates to washing agents having controlled foaming properties containing the above combination of surface-active compounds.
