摘要

Cosmetic composition (A) for dyeing keratinous fibers, particularly hair, comprises polymerizable cyanoacrylate monomer (I), a suspension (II) of metallic nanopartilces coated with organosulfur monolayer and a liquid organic solvent (III). Independent claims are included for: (1) a process of coloring keratinous fibers such as hair, comprising applying (A) on the keratinous fibers; (2) process of treatment of keratinous matters, such as hair, comprising applying a (complete) hair perming reducer, an oxidation dye, a bleach, shampoo or a hair styling or alkaline hair straightening product and applying (A) before/after the application of the given composition; and (3) a device containing multiple compartments or a kit, comprising a first compartment comprising a composition of (I) and optionally an anionic/radical polymerization inhibitor in an organic solvent and a second compartment comprising a suspension of metallic nanoparticles coated with organosulfate monolayer in the organic solvent, where the nucleophilic agent is present in either of the two compartments or present in a third compartment.
