## Abstract

Non-ionic products of the formula: R--X--[C.sub.2 H.sub.3 (OCH.sub.2 CH.sub.2).sub.n (OH)--CH.sub.2 --Y--R' in which R and R' denote alkyl or alkenyl radicals having from 6 to 20 carbon atoms, the sum of the numbers of carbon atoms in R and R' being 24 to 32; X denotes an oxygen atom, a sulphur atom or a sulphoxide group; Y denotes a sulphur atom, a sulphoxide group or a methylene group (if Y denotes methylene, the sum of the numbers of carbon atoms in R and R' is 22 to 30); and n denotes an integer or decimal number from 1 to 40 are disclosed. These non-ionic compounds are suitable for use in pharmaceutical or cosmetic applications, in particular for the care of the skin or hair.
