Abstract (en)
[origin: EP0272574A2] A liquid mixture of propylene oxide/ethylene oxide derivatives of alcohols of the formula R-O-(C3H5O)1-2-(C2H4O)6-8-H in which R is an alkyl or alkenyl radical which is linear or methyl-branched in position 2 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 %, is, by reason of its physical and washing properties, suitable as readily biodegradable substitute for alkylphenol ethoxylates.
