Abstract:
The invention relates to a cosmetic composition, especially for bleaching human keratin fibers dyed with oxidation dyes and/or direct dyes, in particular the hair, comprising, in a cosmetically acceptable medium at a pH of between 1.5 and 9, sulfinic acid derivatives of formula (I). The invention also relates to the novel compounds of formula (I), to multi-compartment devices for dyeing and bleaching said fibers and to the bleaching process using this composition.
Abstract:
The invention concerns novel pyrazolo[1,5-a]pyrimidines comprising at least a cationic group Z, Z being selected among quaternized aliphatic chains, aliphatic chains comprising at least a quaternized cycle, and their use as oxidation base for dyeing keratin fibers, the dyeing compositions containing them, and the oxidation dyeing methods using them.
Abstract:
Compositions, such as ready-to-use compositions for oxidation dyeing of keratinous fibers, and in particular human keratinous fibers such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation dye, and at least one enzymatic system, the enzymatic system comprising (i) at least one enzyme immobilized in at least one sol-gel matrix and optionally (ii) at least one suitable donor, wherein said at least one enzyme is chosen from 2-electron oxidoreductases, 4-electron oxidoreductases and peroxidases, with the proviso that when said at least one enzyme is chosen from 2-electron oxidoreductases, said at least one enzymatic system comprises at least one suitable donor, and with the proviso that when said at least one enzyme is chosen from peroxidases, said at least one enzymatic system further comprises at least one source of hydrogen peroxide chosen from hydrogen peroxide and at least one enzymatic system which generates hydrogen peroxide in situ, as well as to processes for dyeing keratinous fibers using these compositions and multicompartment device or dyeing kits comprising these compositions.
Abstract:
The present invention relates to the use, for dyeing keratin fibres, of at least one heterocyclic cationic amine and of at least one compound chosen from an aldehyde, a ketone, a quinone and a diiminoisoindoline or 3-aminoisoindolone derivative, in order to obtain, by reaction without an oxidizing agent, a coloration of the said keratin fibres. The invention also relates to dye compositions comprising these compounds and to dyeing agents for using them.
Abstract:
The invention relates to the use of heterocyclic quaternary polyammonium polymers as protective agent for keratin fibres, to cosmetic compositions using them and to method for treating hair with the aid of these polymers.
