  • Patent number: 11266583
    Abstract: Provided is a cosmetic method for treating perspiration and, optionally, the body odors related to thereto, e.g. underarm odors, with an effective amount of particles of an expanded amorphous mineral material or of a composition thereof, and more particularly containing expanded perlite particles. The composition can contain, in a cosmetically acceptable carrier, at least the above particles and at least one antiperspirant salt or complex. Also provided is a composition containing, in a cosmetically acceptable carrier, at least the above particles and at least one antiperspirant salt or complex. Also, provided is an anhydrous solid composition in stick form comprising in a cosmetically acceptable carrier: (i) more than 1% by weight, relative to the total weight of the composition, of expanded mineral particles as defined above; and (ii) at least one fatty phase comprising at least one volatile oil and/or at least one non-volatile oil and a structuring agent.

  • Patent number: 9913786
    Abstract: The present invention relates to a composition in the form of an oil-in-water emulsion, comprising, in a physiologically acceptable medium: a) at least one aqueous phase; and b) at least one oily phase comprising at least one apolar non-volatile hydrocarbon-based oil and at least one pasty apolar lipophilic hydrocarbon-based compound; and c) at least one hydrophilic gelling polysaccharide; and d) at least one mixture of emulsifying nonionic surfactants comprising (i) at least one fatty acid ester of polyol and (ii) at least one polyalkylene glycol ester. The present invention also relates to a cosmetic care process for moisturizing a human keratin material, in particular the skin, characterized in that it comprises the application to the surface of the said keratin material of a composition as defined previously.

  • Patent number: 8658186
    Abstract: The invention relates to a fragrancing aqueous transparent solid composition in a cosmetically acceptable support: a) at least one aqueous phase and b) at least one fatty acid salt (soap) and c) at least one oxyethylenated fatty alcohol of formula (I) below: CH3(CH2)x—CH2—(CH2CH2OH)y—OH??(I) in which x is an integer greater than 20 and preferably ranging from 21 to 30 and y varies from 1 to 20 and d) at least one fragrancing substance. The present invention also relates to a method of stabilizing a fragrancing aqueous transparent solid composition comprising, in a cosmetically acceptable support: a) at least one aqueous phase and b) at least one fatty acid salt and c) at least one fragrancing substance, characterized by the fact that it comprises adding, to said composition, at least one polyoxyethylenated fatty alcohol of formula (I).

  • Patent number: 8636990
    Abstract: The subject-matter of the invention is a cosmetic method for scenting a human keratinous substance which consists in applying, to the said substance, a scenting composition comprising, in a cosmetically acceptable medium, at least 0.3% by weight of at least one scenting substance and at least particles of an expanded amorphous mineral material and in particular of an expanded amorphous mineral material resulting from at least one volcanic rock and more particularly expanded perlite particles. Another subject-matter of the present invention is a cosmetic method for treating human body odors, in particular axillary odors, which consists in applying, to the surface of the skin, an effective amount of the said composition. The invention relates to specific scenting compositions comprising, in a cosmetically acceptable medium: a) at least 0.3% by weight, with respect to the total weight of the composition, of a scenting substance; b) at least the said particles.
