摘要:
The agent for dyeing keratin fibers contains one or more aryl and/or benzyl alcohols, one or more oxidizing enzymes, especially vanillyl oxidase, derivatives of vanillyl oxidase or galactose oxidase, and a nucleophilic compound that forms a dye for dyeing keratin fibers in the presence of the alcohols and enzymes. A method for dyeing keratin fibers with this agent is also disclosed. Two-component kits for performing the method of dyeing keratin fibers include a first compenent (A) and a second component (B) separate from the first component. The first component (A) includes the nucleophilic compound, the alcohol and optionally the oxidizing enzyme. The second component (B) includes the oxidizing enzyme when it is not included in the first component or more alcohol.

The one or more developer compounds include at least one substituted 2-aminoalkyl-1,4-diaminobenzene compound of the formula (I): New substituted 2-aminoalkyl-1,4-diaminobenzene compounds of formula (I) are described.
摘要:
Dyes, containing N-benzyl-p-phenylenediamine derivatives of the general formula (I) or their physiologically compatible salts, for keratin fibers, and new N-benzyl-p-phenylenediamine derivatives.
摘要:
The aqueous or aqueous-alcoholic oxidative dye precursor composition includes 1,4-diamino-2-methoxymethylbenzene, or a physiologically compatible salt thereof, as developer substance and one or more conventional coupler compounds. A ready-to-apply hair dyeing mixture having a pH of 6 to 10.5 is made by mixing the aqueous or aqueous-alcoholic oxidative dye precursor composition with an oxidizing agent, such as 6% hydrogen peroxide in a weight ratio of 5:1 to 1:3. The compositions may also contain conventional cosmetic additive ingredients and direct-dyeing dye compounds.
