Multicomponent Packaging Unit and Method for Reductive Dyeing of Corneal Fibers

摘要

A multi-component packaging unit (kit-of-parts) for decreasing discoloration of colored keratin fibers, in particular human hair, which comprises - a container (A) containing a cosmetic agent (a) and - a container (B) containing a cosmetic agent (b), which are made separately from one another, - the agent (a) of the container (A) contains one or more sulfur-based reducing agents and - 1 agent (b) of the container (B) contains one or more metal salts of the group of tin (II) salts, iron (II) salts, manganese (II) salts, titanium (II) salts and titanium (III) salts. Another object of the invention is a reductive bleaching process of keratin fibers stained with the multicomponent packaging unit.
