Liquid nonionic surfactant mixtures

摘要

The invention relates to a liquid mixture of propylene oxide-ethylene oxide derivatives of alcohols corresponding to the following formula R-O-C3H5O1-2-(C2H4O)6-8-H in which R is a linear alkyl or alkenyl radical which may be methyl-branched in the 2-position, and which has the following chain distribution: C8=0 to 5%, C9-10=75 to 90%, C11-12=5 to 15%, C13-14=4 to 10%, C15-16=0 to 3%. By virtue of its physical and washing-active properties, the mixing is suitable as a readily biodegradable substitute for alkylphenol ethoxylates.
