Abstract
An emulsifying composition comprising from 10 to 40 weight % of a mixture alkylpolyglycosides and from 90 to 60 weight % of at least one fatty alcohol of formula R'OH, where R' is a saturated or unsaturated alkyl radical having from 12 to 18 carbon atoms, where the mixture of alkylpolyglycosides comprises: EQU R.sub.1 O(G.sub.1)X.sub.1 (I) in which R.sub.1 is a saturated or unsaturated alkyl radical having 12 or 14 carbon atoms, G.sub.1 is the residue of a sugar and X.sub.1 is between 1 and 5; PA1 (ii) an alkylpolyglycoside of formula (II) EQU R.sub.2 O(G.sub.2)X.sub.2 (II) in which R.sub.2 is a saturated or unsaturated alkyl radical having 16 carbon atoms, G.sub.2 is the residue of a sugar and X.sub.2 is between 1 and 5; and PA1 (iii) an alkylpolyglycoside of formula (III) EQU R.sub.3 O(G.sub.3)X.sub.3 (III) in which R.sub.3 is a saturated or unsaturated alkyl radical having 18 carbon atoms, G.sub.3 is the residue of a sugar and X.sub.3 is between 1 and 5, PA1 the ratio by weight of the alkylpolyglycosides of formula (I) to the alkylpolyglycosides of formulae (II) and (III) being between 0.4 and 5. The emulsifying composition is useful as self-emulsifiable agent for the preparatio…
