ABSTRACT:
Surface-active statistical oligomers of the formula ##STR1## in which R.sub.1 denotes a C.sub.4 -C.sub.30 optionally substituted, aliphatic or cycloaliphatic radical, R.sub.2 denotes a C.sub.5 -C.sub.20 alkyl radical, m and n, which are identical or different, denote a number from 1 to 25, X denotes --CH.sub.2 --, --O-- or ##STR2## in which u=0 or 1, and Y denotes a group: ##STR3## (in which M denotes a hydrogen atom or an alkali metal or alkaline earth metal), an amine group, an amine salt or ammonium are described as well as processes for their preparation and novel intermediates used in these processes. These surface-active oligomers possess a low aggressiveness towards the skin and mucous membranes and ae suitable for use in cosmetic compositions and for dispersing hydrocarbons.
