Such liquid THEREOF FOR PREPARING COSMETC emulsifiers are described in the international application pub EMULSIONS, AND METHOD FOR lished under number WO 00/56438 or else in the French PREPARING SAME patent application published under number FR 2830 464. Such liquid compositions, owing to their very lipophilic The invention relates to the provision of novel emulsifying nature, do not make it possible to prepare oil-in-water emul compositions that can be used in the preparation of cosmetic sions which are sufficiently stable and/or which have sensory and/or pharmaceutical formulations in particular for topical properties that are sufficiently satisfactory for the final client. SC. 10 In the context of their research on the constant improve Sugar-derived emulsifiers have been developed for more ment of emulsifiers for preparing “oil-in-water emulsions than about twenty years and their commercial Success which do not have the abovementioned drawbacks, the inven requires no further demonstration. They consist of a mixture tors have developed novel emulsifying compositions, and of alkyl polyglycosides and/or alkenyl polyglycosides and of also a novel method for preparing oil-in-water emulsions, fatty alcohols, and are available on the market in solid form, 15 which make it possible to prepare emulsions that are stable in whether as flakes, powder or beads. Such emulsifiers are the presence of thermosensitive and/or Volatile ingredients, described in the international applications published under without the appearance of phase inversion phenomena during numbers WO92/06778, WO95/13.863, WO 96/37285. WO their preparation, and which provide said emulsions with 98/47610 or FR 2784904. They make it possible to prepare advantageous sensory properties, such as a rich and creamy stable emulsions in oil-in-water or water-in-oil form. The feel. presence of an amount of fatty alcohols of greater than 30% According to a first aspect, the Subject of the invention is a by weight for 100% of the weight of these compositions pulverulent composition C1 comprising, for 100% of its creates a consistency and sensory properties which are advan weight: tageous, for instance a rich and creamy feel of the final emul from 5% by weight to 70% by weight, more particularly S1O. 25 Patent application FR 2 756 195 discloses emulsifying from 10% by weight to 50% by weight, of at least one compositions intended for the preparation of emulsions with compound of formula (I): improved Stability, and particularly intended for preparing stable fluid emulsions. These compositions comprise: i) from 30% to 90% by weight of a mixture of at least one 30 in which the R radical represents a saturated linear aliphatic alkyl polyglycoside of which the linear or branched, saturated radical containing from 12 to 22 carbon atoms, G represents or unsaturated alkyl radical contains from 8 to 22 carbon the residue of a reducing Sugar selected from the group con atoms and at least one alkyl polyglycoside of which the alkyl sisting of glucose, Xylose and arabinose, and X represents a radical is an oleyl radical or an isostearyl radical, and decimal number greater than or equal to 1 and less than or ii) from 10% to 70% by weight of at least one fatty alcohol 35 equal to 10; of which the linear or branched, saturated or unsaturated alkyl from 95% by weight to 30% by weight, more particularly radicals contain from 8 to 22 carbon atoms. from 90% by weight to 50% by weight, of one or more Application EP 0992 508 discloses emulsifying composi alcohols of formula (II): tions intended for improving the whiteness of the emulsions prepared, and which comprise: 40 R" OH (II) i) from 5% to 60% by weight of a mixture of alkyl polyg in which the R' radical, which may be identical to or different lycosides comprising, for 100% of its weight: than the R radical as defined above, represents a saturated from 30% to 95% by weight of a mixture of cetyl polyg linear aliphatic radical containing from 12 to 22 carbon lycosides and Stearyl polyglycosides, atoms, and in which at least 90% by volume of the particles from 70% to 5% by weight of a mixture of arachidyl 45 have a diameter of less than or equal to 250 micrometers, and polyglycosides and behenyl polyglycosides; more particularly a diameter of less than or equal to 150 ii) from 95% to 40% by weight of one or more fatty alco micrometers. hols of which the linear or branched, saturated or unsaturated The expression “saturated linear aliphatic radical contain alkyl radicals contain from 14 to 22 carbon atoms.
