The present invention provides a composition for lanthionizing keratin fibers comprising at least one multivalent metal hydroxide and at least one complexing agent effective for dissociating said at least one multivalent metal hydroxide in sufficient quantity to effect lanthionization of said keratin fibers. In one embodiment, the complex that is formed between the complexing agent and a metal ion from the multivalent metal hydroxide is soluble in water. The invention is also drawn to a method for lanthionizing keratin fibers to achieve relaxation of the keratinous fibers.
L'invention concerne une composition de lanthionisation des fibres de kératine, comprenant au moins un hydroxyde métallique polyvalent et au moins un agent complexant capable de dissocier ledit hydroxyde métallique polyvalent en quantité suffisante pour opérer la lanthionisation des fibres de kératine. Dans un mode de réalisation, le complexe formé entre l'agent complexant et un ion métallique provenant de l'hydroxyde métallique polyvalent est soluble dans l'eau. L'invention concerne également un procédé de lanthionisation des fibres de kératine permettant de défriser les fibres kératiniques
