Title (EN) MEANS AND PROCESS ALLOWING HAIR COLORATION BY OXIDATION
(FR) MOYEN ET PROCEDE PERMETTANT LA COLORATION DE CHEVEUX PAR VOIE OXYDATIVE
Abstract: front page image
(EN)Composition and process allowing hair coloration by oxidation by using as a colorant precursor, at least a compound of the general formula: (FORMULA) wherein X=CH2, O, S; NH, NR", CH(OH), CHR", CH(NH2), CH(CH3); Y=O, NH; Z=O, S, NH; R=H, OH, R", OR", NR"2, NO2, halogen and R" = alkyl from C1 to C5. The compositions allowing the capillary dying may comprise, besides the colorant precursors of the formula (I), known coloring precursors and direct action colorants, and particularly natural amino acids, the esters and/or amides thereof, as well as redox catalysts. The disclosed compositions, exhibiting a certain ratio of colorant precursors of formula (I) are toxicologically harmless and give stable dyes with a natural look; with the defined precursors, there are provided dyes with stronger shades than those obtained by using di- or polyphenols as colorant precursors.
(FR)L"on realise aussi bien la composition que le procede permettant une coloration de cheveux par voie oxydative en utilisant, en tant que precurseur de colorant, au moins un compose de formule generale (FORMULE) formule dans laquelle X = CH2, O, S, NH, NR", CH(OH), CHR", CH(NH2), CH(CH3); Y = O, NH; Z = O, S, NH; R = H, OH, R", OR", NR"2, NO2, halogene et R"= alkyle C1 a C5. Les compositions permettant la teinture capillaire peuvent comporter, a part des precurseurs de colorant de formule (I), des precurseurs de colorant connus et de colorants a action directe, en particulier aussi des acides amines naturels, leurs esters et/ou leurs amides, ainsi que des catalyseurs redox. Les compositions decrites, presentant un certain taux de precurseurs de colorant de formule (I) sont toxicologiquement sans probleme et produisent des teintures stables d"un effet naturel; avec les precurseurs definis l"on obtient de maniere generale des teintures a nuances plus profondes, que lors de l"utilisation de di- ou de polyphenols en tant que precurseurs de colorant.
