Abstract

An emulsifying composition, characterised in that it contains by weight, excluding impurities, (i) 1 to 98% by weight of a mixture of alkyl glycosides R1O(G1)g1(G2)g2(G3)g3(G4)g4(G5)g5, (ii) 1 to 90% by weight of a mixture of alcohol esters R2OZ, (iii) 1 to 90% of an alcohol R3OH, and (iv) 4 to 90% of a mixture of alkyl glycoside esters R4O(X1)x1(Z)z1(X2)x2(Z)z2(X3)x3(Z)z3(X4)x4(Z)z4(X5)x5(Z)z5, is disclosed In accordance with the composition, R1 is a hydrocarbon radical, linear or branched, saturated or unsaturated, having 10 to 22 carbon atoms. G1, G2, G3, G4, G5 are identical or different residues of -oses selected from glucose, galactose, mannose, fructose, ribose, xylose and arabinose, g1, g2, g3, g4 and g5 being equal to 0 or 1, the sum of g1, g2, g3, g4 and g5 being at least equal to 1. The composition has emulsifying capacity in the presence of electrolytes or in the case of paraffin-based emulsions.
