摘要:
The invention relates to a method for dyeing keratin fibers, especially human hair. The inventive method comprises the following steps: optionally applying a pretreatment agent M1 to the fiber, using a dye M2 on the fiber which is optionally mixed immediately before application to the fiber from a component M2a, containing at least one oxidative dye pre-product of the developer type and/or an indole and/or indole derivative and a component M2b, containing an oxidative dye and/or an enzyme. If desired, a third agent M3 is added to the individual agents M2a or M2b before mixing them or to the mixture M2, and said dye M2 is rinsed from the fiber after a period of 5–10 minutes. At least one of the agents M1, M2a, M2b or M3 contains a compound from the vitamin B6 group. The invention further relates to hair pretreatment agents, to agents for dyeing keratin fibers, to their packing in corresponding kits and to the use thereof. The inventive compounds of the vitamin B6 group and their physiologically acceptable salts are useful as coupling components in the production of oxidative dyes that contain conventional developer and/or coupling compounds and/or indole and/or indole derivatives in a substrate appropriate for dyeing. The inventive compounds are further useful as active substances that improve the hair structure.
摘要:
An alkalization-effecting solid composition that contains, as an agglomerate at least one alkalizing agent and at least one chelating agent. The chelating agents are present along with the alkalizing agent in the same particle of the agglomerate. Hydrogen peroxide decomposition during the dissolution process of alkalization-effecting compositions in the presence of H2O2 can be greatly reduced if the composition to be dissolved is this alkalinization-effecting solid composition.

摘要:
A shaped body for coloring keratinous fibers consisting of at least one dissolution accelerator and at least one oxidation dye precursor of the secondary intermediate type, contained within a cosmetically acceptable carrier. The shaped body is free from oxidation dye precursors of the primary intermediate type. Also disclosed are a method for coloring keratin fibers and a kit containing these ingredients.
摘要:
An agent for dyeing keratin-containing fibers, in particular, human hair, to give the fibers fashionable bright colors. The agent comprises A) an oxidizing agent, B) a CH-acidic compound and C) a reactive carbonyl compound. The invention also includes a process for dyeing keratin-containing fibers with the agent.
摘要:
A hybrid dye is provided that is useful for coloring keratin fibers and skin. The hybrid dye has the structure X-S-Y, where X is derived from a substantive dye, Y is derived from an oxidation dye precursor or a melanin precursor, and S is a direct bond or spacer group. The present invention also provides a composition for coloring keratin fibers that contains the hybrid dye.

摘要:
The process of coloring keratin-containing fibers by contacting the fibers with an isatin derivative corresponding to formula (I): ##STR1## in which R.sup.1 is a hydroxy group, an optionally C.sub.1-4 -alkyl- or phenyl-substituted amino group, a C.sub.3-8 alkenyl, dihydroxy-(C.sub.3-6)-alkyl, trihydroxy-(C.sub.4-6)-alkyl, tetrahydroxy-(C.sub.5-6)-alkyl, pentahydroxy-C.sub.6 -alkyl, C.sub.2-4 -aminoalkyl, C.sub.1-4 -sulfoalkyl group, an optionally C.sub.1-4 -alkyl-substituted 2-furylmethyl, 2-thienylmethyl, 2-pyridylmethyl, 3-pyridylmethyl, 4-pyridylmethyl group or an aralkyl group corresponding to formula (II): ##STR2## in which R.sup.6 and R.sup.7 independently of one another represent hydrogen, halogen atoms, hydroxy groups, amino groups optionally substituted by C.sub.1-4 alkyl or phenyl, C.sub.1-4 alkyl groups, C.sub.1-4 alkoxy groups, carboxy groups or sulfo groups and R.sup.8 is hydrogen, a C.sub.1-4 alkyl group or a C.sub.2-4 hydroxyalkyl group and x=0, 1 or 2, and R.sup.2, R.sup.3, R.sup.4 and R.sup.5 independently of one another represent hydrogen, hydroxy groups, halogen atoms, nitro groups, sulfo groups, carboxyl groups, C.sub.1-4 alkyl groups, C.sub.1-4 alkoxy groups or NR.sup.9 R.sup.10 groups, wherein R.sup.9 and R.sup.10 independently of one another represent hydrogen, C.sub.1-4 alkyl groups or C.sub.2-4 hydroxyalkyl groups, and two adjacent groups R.sup.3, R.sup.4 and R.sup.5 may represent an alkylenedioxy group containing 1 to 4 carbon atoms, and water-soluble salts thereof.
摘要:
1,3-disubstitued nitrobenzenes of the general formula I: ##STR1## in which X is a hydroxyl group or an amino group and R.sup.1 is hydrogen or a C.sub.1-4 alkyl group and their salts are suitable for use as an oxidation dye precursor of the coupler type, together with prior art primary intermediate components, for the production of oxidation dyes, preferably for the production of hair colorants. With developers of the p-phenylenediamine, p-aminophenol, 2.5-diaminopyridine, and 2,4,5,6-tetraaminopyrimidine types, primarily brown hues with great light stability are formed.
