Claim 1

Derivatives of fatty alcohols, characterized by the following general formula: R.sub.1 --/A--(X).sub.y --B/.sub.p --R.sub.2 in which p is equal to 1 or 2, y=0 or 1, A-(X) y --B is a hydrocarbon chain of 11 to 50 carbon atoms, wherein said hydrocarbon chain is unsubstituted or substituted by one or more alkyl groups of 1 to 3 carbon atoms, or by one or more OR a groups, R a representing H or an alkyl group of 1 to 3 carbon atoms, in which: A and B, identical or different, are saturated or unsaturated aliphatic chain; X is a saturated or unsaturated hydrocarbon chain R 1 and R 2 , identical or different, represent: a group of formula (A): ##STR58## containing a single or a double bond and being unsubstituted or substituted by one or more --CH 3 and/or --OH and/or --OR groups, R being defined below, and/or an oxy (=0) group, a --OR group, in which R represents a hydrogen atom or an alkyl group of 1 to 3 carbon atoms, or a ##STR59## group, in which R' represents a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, provided that at least one of the pair of R 1 and R 2 represent a group of the formula (A).
