AGENT FOR OXIDATIVELY DYEING HAIR CONTAINING SPECIFIC COMBINATIONS OF DEVELOPERS AND COUPLERS

摘要

The subject matter of the present invention relates to an agent for oxidatively dyeing keratinous fibers, comprising, in a cosmetic carrier, (A) 4,5-diamino-1-(2-hydroxyethyl)-1H-pyrazole and/or one of the physiologically acceptable salts thereof as a developer, (B) at least one p-diaminobenzene derivative from the group of p-toluylenediamine, 2-(2,5-diaminophenyl)ethanol, and/or one of the physiologically acceptable salts thereof as a developer, (C) at least one m-diaminobenzene derivative from the group of 2-(2,4-diaminophenoxy)ethanol, 1-methoxy-2-amino-4-(2′-hydroxyethylamino)benzene, 2,6-bis(2′-hydroxyethylamino)-1-methylbenzene, and/or one of the physiologically acceptable salts thereof as a coupler, and (D) at least one m-aminophenol derivative from the group 3-aminophenol, 5-amino-2-methylphenol, and/or one of the physiologically acceptable salts thereof as a coupler, wherein the molar ratio of all developers of group (A) included in the agent to all developers of group (B) included in the agent, i.e., the molar ratio (A)/(B), has a value of at least 1.2.
