The invention relates to a solid composition in the form of a water-in-oil emulsion comprising, in a cosmetically acceptable carrier: (i) at least one discontinuous aqueous phase, (ii) at least one fatty phase comprising at least one particular wax, (iii) at least one silicone emulsifier selected in the group consisting in alkyldimethicone copolyols of particular formula (I) and dimethicone copolyols of particular formula (II) and mixtures there of (iv) and at least one antiperspirant active agent and/or one deodorant active agent. The invention relates to a method for treating body odours associated with human perspiration, and in particular body odours which are especially underarm odours. The invention relates to a method for preparing a solid composition in the form of a water-in-oil emulsion as defined above. 

Solid antiperspirant and/or deodorant composition in the form of a water-in-oil emulsion based on silicone emulsifiers and on waxes; method for treating body odours

A color-changing composition for caring for and/or making up keratin materials is disclosed. The composition comprises: &#x2014;a physiologically acceptable medium including at least an aqueous phase, &#x2014;color-changing microcapsules, said microcapsules having a size ranging from 50 &#x3bc;m to 1000 &#x3bc;m, preferably from 80 &#x3bc;m to 800 &#x3bc;m, in particular from 100 &#x3bc;m to 400 &#x3bc;m, and comprising: (A) a core, having preferably a size ranging from 20 &#x3bc;m to 800 &#x3bc;m, comprising at least one colorant and preferably at least one binder, said colorant(s) including preferably at least one inorganic pigment preferably selected from iron oxide(s), and (B) a pressure-breakable wall layer surrounding said core, having preferably a thickness of 10 &#x3bc;m to 300 &#x3bc;m, comprising at least one colorant and preferably at least one binder, said colorant(s) including preferably at least titanium dioxide particles, Wherein said microcapsules includes at least 70% by weight of colorant(s), compared to the total weight of said microcapsules.

Color-changing composition

A changing color composition for caring for and/or making up keratin materials is disclosed. The composition comprises in a physiologically acceptable medium, at least: a) microcapsules containing releasable colorant(s), said microcapsules comprising: a core comprising one organic material, at least one layered coating surrounding said core, the layered coating comprising at least one polymer, at least one colorant, and advantageously at least one lipid-based material, b) at least 3% by weight, preferably at least 5 by weight, more preferably at least 8% by weight and advantageously at least 10% by weight relative to the weight of the composition of an aqueous phase comprising water and at least one compound chosen from polyols, glycols and C-Cmonoalcohols, and mixtures thereof, c) at least one hydrophilic gelifying agent, d) and optionally 0.1 to 70% by weight relative to the weight of the composition, of additional cosmetic ingredient(s) selected from volatile and non-volatile silicon or hydrocarbon oils, surfactants, filler, thickening agents, film forming agents, polymers, preservatives, silicon elastomer, self-tanning agents, additional non-entrapped colorants, cosmetic actives, pH regulators, perfumes, and mixtures thereof.

Colour changing composition

The invention relates to a solid composition in the form of a water-in-oil emulsion comprising, in a cosmetically acceptable carrier: (i) at least one discontinuous aqueous phase, (ii) at least one fatty phase comprising at least one particular wax, (iii) at least one silicone emulsifier selected in the group consisting in alkyldimethicone copolyols of particular formula (I) and dimethicone copolyols of particular formula (II) and mixtures there of (iv) and at least one antiperspirant active agent and/or one deodorant active agent. The invention relates to a method for treating body odors associated with human perspiration, and in particular body odors which are especially underarm odors. The invention relates to a method for preparing a solid composition in the form of a water-in-oil emulsion as defined above. 

The present invention relates to a deodorant cosmetic composition comprising: (a) at least one lipophilic salicylic acid derivative of formula (I) below, or a salt thereof: (b) at least one antiperspirant aluminum salt; in an (a)/(b) weight ratio of less than 1/20. The invention also relates to a cosmetic process for treating human perspiration and human body odor, in particular underarm perspiration and underarm odor, using this composition. The invention relates to the use of a combination of at least (a) one lipophilic salicylic acid derivative of formula (I), or a salt thereof, and of at least (b) one antiperspirant aluminum salt, in an (a)/(b) weight ratio of less than 1/20, as a deodorant active agent in a cosmetic composition. 

Deodorant cosmetic composition comprising a combination of a lipophilic salicylic acid derivative and an antiperspirant aluminium salt

An anhydrous antiperspirant stick comprising: at least one antiperspirant active agent chosen from aluminium chlorohydrate and its complexes, such as complexes with zirconium; at least one solidifying agent chosen from natural waxes and synthetic waxes; and, at least one base chosen from inorganic and organic bases, such as anhydrous inorganic and organic bases. A method for reducing or eliminating the yellowing of anhydrous antiperspirant sticks based on waxes and on aluminium chlorohydrate or its complexes, by the inclusion therein of at least one base chosen from inorganic and organic bases.
