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 method for preparing an oil-in-water cosmetic emulsion by emulsification of an aqueous phase D1 with a fatty phase D2, comprising a step a1) of preparing said aqueous phase D1 which comprises mixing an effective amount of the pulverulent composition C1 with water or an aqueous dispersion of one or more cosmetically acceptable hydrophilic ingredients, wherein pulverulent composition C1 comprise, for 100% of its weight:
from 5% by weight to 70% by weight, of at least one compound of formula (I):
R—O-(G)x-H  (I)in which the R radical represents a saturated linear aliphatic radical containing from 12 to 22 carbon atoms, G 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 (II):
R′—OH  (II)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 12 to 22 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.
