Composition comprising 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazol-1-one, 4,5-diamino-1-(ß-hydroxyethyl)pyrazole and 2 chloro 6 methyl 3 aminophenol

摘要

Composition (I) comprises: at least one first oxidation base comprising 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo [1,2-a] pyrazol-1-one and their addition salts, at least one second oxidation base comprising 4,5-diamino 1-(beta -hydroxyethyl) pyrazole and their addition salts, and at least one linker comprising 2-chloro-6-methyl 3-amino phenol and their addition salts, in a medium. Independent claims are included for: (1) process for dyeing keratin fibers comprising applying (I) to the keratin fibers in the presence of oxidizing agents for a time sufficient to develop the desired coloration; and (2) multi-compartment device in which a first compartment contains a dye composition and a second compartment contains one or several oxidizing agents.
