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

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 and at least one second oxidation base comprising 4,5-diamino 1-(beta -hydroxyethyl) pyrazole and their addition salts, in a medium. Independent claims are included for: (1) process for dyeing keratin fibers comprises applying (I) to the keratin fibers in the presence of one or more 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.
