Alkyl and alkenyl diethanolamine compounds as solubilizers for low-foam surfactants

摘要

Aqueous low-foam cleaning compositions containing at least one surfactant which is a water-soluble or water-emulsifiable polyalkylene glycol ether of a long-chain alcohol, and at least one diethanolamine derivative of the formula <IMAGE> (I) <IMAGE> (IIa) <IMAGE> (IIb) in which R1 and R2 are linear or branched alkyl or alkenyl radicals containing 8 to 14 carbon atoms for R1 and 9 to 17 carbon atoms for R2, and r, s, t, u, v and w are integers of from 1 to 3.
