Abstract: The invention relates to an oxidizing agent for use in a process for permanently reshaping the hair, this agent comprising: a first component comprising a composition containing at least one oxidizing agent in aqueous medium, a second component comprising a composition containing one thickening polymer in aqueous medium, as an aqueous or oily dispersion or as a reverse emulsion, with the proviso that said thickening polymer is not quaternary hydroxyethylcellulose; the first and the second component are mixed with each other at the time of use in order to obtain a ready-to-use oxidizing composition to be applied to the hair in order to reform the hair's disulfide linkages.

Abstract: The invention relates to a reducing agent intended to be used in a process for permanently reshaping the hair, this agent comprising: a first component comprising at least one thiol-bearing reducing agent in aqueous medium, and a second component comprising at least one thickening polymer in aqueous medium, said thickening polymer being in the form of an aqueous dispersion, an oily dispersion, or a reverse emulsion, with the proviso that said thickening polymer is not vinylpyrollidone-styrol, carboxymethylcellulose, acrylic acid homopolymers, quaternary hydroxyethylcellulose, and cross-linked polymers of polymethacrylic acid; wherein the first and second components are to be mixed with each other at the time of initiating the permanently reshaping of the hair to obtain a ready-to-use reducing composition.

Abstract: A composition comprising the combination of at least one retinoid selected from the group consisting of vitamin A (retinol) and the bioconvertible precursors of vitamin A and at least one polyamine polymer.

Abstract: A synegistic system based on a phosphonic acid derivative and on a metabisulphite, for stabilizing ascorbic acid. The invention also relates to compositions, in particular cosmetic and dermatological compositions, containing ascorbic acid and this stabilizing system, and to the use of these compositions in the cosmetics and/or dermatological fields.

Abstract: Cosmetic and/or dermatological compositions containing a non-photocatalytic metal oxide and tocopherol and, optionally, a metal-inactivating complexing agent are effective for inhibiting the light-induced peroxidation of lipids, and in particular lipids of sebaceous origin such as squalene.

Abstract: The invention relates to the use of a spin trap employed as an electron paramagnetic resonance measurement probe, in a cosmetic or dermatological composition for the light-protective, anti-ageing and/or anti-acne treatment of the skin. In particular, this spin trap is encapsulated in lipid vesicles which are capable of diffusing into the deep layers of the skin.

Abstract: The invention relates to a cosmetic and/or dermatological composition comprising at least one superoxide dismutase and at least one porphyrin. In a composition of this kind the porphyrin synergically reinforces the anti-free radical action of the superoxide dismutase.The composition is used in particular to combat cell ageing and/or for the protection of the skin, hair and/or mucosae against the harmful and/or unaesthetic effects caused by oxygen-containing free radicals.

Abstract: A stabilized composition capable of releasing an active agent in contact with the skin, contains at least two precursors of this same active agent, capable of simultaneously releasing this active agent by at least two different specific enzymatic reactions in order to release a large amount of active agent at a faster rate than the sum of the rates of the first enzymatic reaction and of the second enzymatic reaction taken separately, the first precursor being chosen from active agent monosaccharide derivatives and active agent amides. The composition is useful for dermatological and/or cosmetic treatments applied topically.
