Powdery emulsifying composition of alkyl polyglycosides, use thereof for preparing cosmetic emulsions, and method for preparing same

摘要

A powdery composition C1 contains for 100% of the mass: 5 to 70 mass % and more particularly 10 to 50 mass % of at least one compound of formula (I): R—O-(G)x—H, wherein R is a linear saturated aliphatic radical including 12 to 22 carbon atoms, G is the remainder of a reducing sugar selected from the group including glucose, xylose and arabinose, and x is a decimal number greater than or equal to 1 and lower than or equal to 10; 95 to 30 mass % and more particularly 90 to 50 mass % of one or more alcohols of formula (II): R′—OH, wherein R′ is a linear saturated aliphatic radical including 12 to 22 carbon atoms identical to or different from R as defined in formula (I), wherein at least 90 vol % of the particles have a diameter lower than or equal to 250 micrometers, more particularly a diameter lower than or equal to 150 micrometers.

1. A pulverulent composition C1 comprising, for 100% of its weight:
from 5% by weight to 70% by weight, of at least one compound of formula (Ic):
R—O-(G)x-H  (Ic)in which the R radical represents a saturated linear aliphatic radical containing from 16 to 18 carbon atoms, (represents the residue of a reducing sugar selected from the group consisting of glucose, xylose and arabinose, and x represents a decimal number greater than or equal to 1 and less than or equal to 10; and
from 95% by weight to 30% by weight, of one or more alcohols of formula (IIc):
R′—OH  (IIc)in which the R′ radical, which may be identical to or different than the R radical as defined above, represents a saturated linear aliphatic radical containing from 16 to 18 carbon atoms, wherein at least 90% by volume of particles in said pulverulent composition have a diameter of less than or equal to 250 micrometers.
