Abstract: The present invention relates to a composition comprising: (a) at least one thiopyridinone compound; and (b) at least one fatty acid comprising 18 or more carbon atoms, wherein the amount of the (b) fatty acid(s) comprising 18 or more carbon atoms in the composition is 10% by weight or more, preferably 12% by weight or more, and more preferably 14% by weight or more, relative to the total weight of the composition. The present invention can provide a composition including (a) thiopyridinone compound(s) with increased stability of the (a) thiopyridinone compound(s) over time, in particular even when the composition is maintained for a relatively long period of time under elevated temperature, and with reduced yellowing just after adding the thiopyridinone compound to the composition.

Abstract: The present invention relates to a composition comprising: (a) at least one thiopyridinone compound; (b) at least one oil; and (c) water, wherein the composition comprises a continuous oil phase comprising the (b) at least one oil, a discontinuous aqueous phase comprising the (a) thiopyridinone compound and (c) water, dispersed in the oil phase, and the weight ratio of the aqueous phase to the oil phase is 1.0 to 10.0. The present invention can provide a composition including (a) thiopyridinone compound(s) with increased stability of the (a) thiopyridinone compound(s), even when the composition is maintained for a relatively long period of time under elevated temperature.

Abstract: The present invention relates to the cosmetic use of at least one compound corresponding to the following formula (I) or (I?) and also their salts, their solvates, their optical isomers and their racemates, as inhibitor of the black or brown colouration of comedones. It also relates to a cosmetic method for preventing the black or brown colouration of the comedones, comprising the topical application, to the skin, of a cosmetic composition comprising at least one compound corresponding to the formula (I) or (I?).

Abstract: The present invention relates to the cosmetic use, as moisturizer for keratin materials, preferably the skin, of one or more 5-oxazolidine-2,4-dione C-glycoside derivatives corresponding to formula (I) below, and also the solvates and/or the isomers (optical, geometric, tautomers) thereof and/or the salts thereof: (I)

Abstract: The present invention relates to the cosmetic use, as moisturizer for keratin materials, preferably the skin, of one or more 5-oxazolidine-2,4-dione C-glycoside derivatives corresponding to formula (I) below, and also the solvates and/or the isomers (optical, geometric, tautomers) thereof and/or the salts thereof: (I)

Abstract: The invention relates to the non-therapeutic cosmetic use of at least one compound of formula (I) as defined below, as an agent for bleaching, lightening and/or depigmenting keratin materials, especially the skin. The invention also relates to a non-therapeutic cosmetic process for depigmenting, lightening and/or bleaching keratin materials, especially the skin, using these compounds (I).
