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 a fatty phase P1 with an aqueous phase P2, comprising at least one step a) of preparing said fatty phase P1 which comprises mixing at least one or more oils and/or one or more waxes, with an effective amount of a pulverulent composition C1,
wherein the pulverulent composition C1 comprises, 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;
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, and in which at least 90% by volume of particles have a diameter of less than or equal to 250 micrometers.
