Abstract

The invention relates to a liquid mixture of propylene oxide-ethylene oxide derivatives of alcohols corresponding to the following formula EQU R--O--C.sub.3 H.sub.5 O.sub.1-2 --(C.sub.2 H.sub.4 O).sub.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: C.sub.8 =0 to 5%, C.sub.9-10 =75 to 90%, C.sub.11-12 =5 to 15%, C.sub.13-14 =4 to 10%, C.sub.15-16 =0 to 3%. By virtue of its physical and washing-active properties, the mixing is suitable as a readily biodegradable substitute for alkylphenol ethoxylates.
