Brief description of the hair coloration on the basis of the derivative of neoflavanols or neoflavanones, manganese salts, of hydrogen peroxide, 1996, (bi) carbonates, alkaline agents, and of metal salts.

摘要

The present invention relates to a process for dyeing keratinous fibers, in particular human keratin fibers such as the hair, in which said fibers are treated by one or more cosmetic compositions containing, taken together or separately into the said compositions, the following ingredients: a) one or more compound (s) of dihydroxyflavonoid (s), néoflavanol (s) or néoflavanone (s); b) one or several salt (s) of manganese; c) of hydrogen peroxide or one or several system (s) generator (s) of hydrogen peroxide; d) one or more (bi) carbonate (s) or one or several system (s) generator (s) of (bi) carbonate (s); e) one or several agent (s) alcalifying agent (s) of the different (s) or (s) bicarbonate (s); and f) one or more metal salt (s) (s) selected (s) from the salts of molybdenum, aluminium, zinc, calcium and rhodium, it being understood that: - the ph of at least one of the compositions comprising at least one of the reagents a), b), d), e) and / or f) is an alkali metal, is greater than 7, - the salt (s) of metal (s), f) is (are) applied (s) in the last step of the coloring process. The process according to the invention has the advantage of dyeing human keratin fibers, with the results of the colorations withstand and, surprisingly, chromatic, with a "a " of the coloration satisfactory.
