Title (EN) DYEING COMPOSITION, METHOD FOR OBTAINING SAME AND USE FOR COLOURING THE SKIN AND/OR KERATINOUS FIBRES
(FR) COMPOSITION DE COLORATION, PROCEDE D"OBTENTION ET UTILISATION POUR LA COLORATION DE LA PEAU ET/OU DES MATIERES KERATINIQUES
Abstract: front page image
(EN)The invention concerns a composition comprising, in a physiologically acceptable medium, an efficient amount of at least a colouring agent precursor selected among compounds comprising at least an aromatic cycle having at least two hydroxyl groups borne by two consecutive carbon atoms of the aromatic cycle, optionally an amino acid comprising at least a thiol group, and an efficient amount of a catalytic system comprising a first constituent selected among the salts and oxides of Mn(II) and/or of Zn(II) and their mixtures and a second constituent selected among alkaline hydrogen carbonates, alkaline-earth hydrogen carbonates and their mixtures, the proportions of the first and second constituents corresponding to formulae: [Mn(II)]/[HCO¿3?] $m(F) 1 with [Mn(II)] 0; [Zn(II]/ [HCO¿3?] $m(F) 1 with [Zn(II)] 0; [Mn(II) + [Zn(II]/ [HCO¿3?] $m(F) 1 with [Mn(II) + Zn(II] 0. The invention is useful for colouring the skin and/or keratinous fibres.
(FR)La composition comprend, dans un milieu physiologiquement acceptable, une quantité efficace d"au moins un précurseur de colorant choisi parmi les composés comportant au moins un cycle aromatique ayant au moins deux groupes hydroxyles portés par deux atomes de carbone consécutifs du cycle aromatique, éventuellement un acide aminé comportant au moins un groupe thiol, et une quantité efficace d"un système catalytique comprenant un premier constituant choisi parmi les sels et oxydes de Mn(II) et/ou de Zn(II) et leurs mélanges et un second constituant choisi parmi les hydrogénocarbonates alcalins, les hydrogénocarbonates alcalino-terreux et leurs mélanges, les proportions du premier et du second constituant étant telles que les formules (I), (II), (III). Application à la coloration de la peau et/ou des matières kératiniques.
