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.
