Abstract

The present invention relates to compositions based on alkyl polyglycosides and fatty alcohols, characterized in that they comprise: *5 to 60% by weight of a mixture of alkyl polyglycosides constituted essentially of: -30 to 95% by weight of a mixture of alkyl polyglycosides of formulae (I) and (II): EQU R.sub.1 O(G.sub.1).sub.x.sub..sub.1 (I) EQU R.sub.2 O(G.sub.2).sub.x.sub..sub.2 (II) in which R.sub.1 and R.sub.2 each represent a linear or branched aliphatic radical having 16 and 18 carbon atoms respectively, G.sub.1 and G.sub.2 each represent a saccharide residue, and x.sub.1 and x.sub.2 each represent a number between 1 and 5; -70 to 5% by weight of a mixture of alkyl polyglycosides of formulae (III) and (IV): EQU R.sub.3 O(G.sub.3).sub.x3 (III) EQU R.sub.4 O(G.sub.4).sub.x4 (IV) in which R.sub.3 and R.sub.4 each represent a linear or branched aliphatic radical having 20 and 22 carbon atoms respectively, G.sub.3 and G.sub.4 each represent a saccharide residue, x.sub.3 and x.sub.4 each represent a number between 1 and 5; *95 to 40% by weight of one or more alcohols of formula R'OH, in which R' is a linear or branched aliphatic radical having 14 to 22 carbon atoms, and preferabl…
