Abstract
The present invention relates to compositions based on alkyl polyglycosides and fatty alcohols which enable stable fluid emulsions to be produced, and which contain These compositions generally comprise: PA1 5 to 60% by weight of a mixture of alkyl polyglycosides essentially consisting of: PA2 10 to 25% by weight of an alkyl polyglycoside of formula (I) EQU R.sub.1 O(G.sub.1).sub.X.sub..sub.1 (I) PA2 10 to 30% by weight of an alkyl polyglycoside of formula (II) EQU R.sub.2 O(G.sub.2).sub.X.sub..sub.2 (II) PA2 0 to 10% by weight of a mixture of alkyl polyglycosides of formulae (III) and (IV): EQU R.sub.3 O(G.sub.3).sub.X.sub..sub.3 (III) EQU R.sub.4 O(G.sub.4).sub.X.sub..sub.4 (IV) PA2 40 to 80% by weight of a mixture of alkyl polyglycosides of formulae (V) and (VI): EQU R.sub.5 O(G.sub.5).sub.X.sub..sub.5 (V) EQU R.sub.6 O(G.sub.6).sub.X.sub..sub.6 (VI) in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each represent a linear or branched aliphatic radical having 12, 14, 16, 18, 20 and 22 carbon atoms respectively, G.sub.1, G.sub.2, G.sub.3, G.sub.4, G.sub.5 and G.sub.6 each represent a saccharide residue, x.sub.1, x.sub.2, x.sub.3, x.sub.4, x.sub.5 and x.sub.6 each r…
