Abstract:
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): 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): 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 wherein the pulverulent composition C1 comprises a non-zero proportion by weight of at least one compound of formula (Ia), corresponding to formula (I) as defined above in which R represents a saturated linear aliphatic radical containing from 20 to 22 carbon atoms, and a non-zero proportion by weight of at least one alcohol of formula (IIa), corresponding to formula (II) as defined above in which R′ represents a saturated linear aliphatic radical containing from 20 to 22 carbon atoms wherein further the pulverulent composition C1 comprises, for 100% of its weight:
