Title
(EN) REDUCING COMPOSITION FOR PERMANENTLY RESHAPING KERATIN FIBERS
(FR) COMPOSITION RÉDUCTRICE POUR LA REMISE EN FORME PERMANENTE DE FIBRES KÉRATINIQUE
Abstract
(EN)
Provided is a reducing composition comprising: a) at least one sulfur-containing reducing agents, b) at least one anionic non-associative polymer; and c) at least one cationic cyclopolymer having at least one ring-structure in the backbone of the polymer and at least one quaternary ammonium group including at least one C 8-C 30 hydrocarbon group. Also provided is a process for permanently reshaping keratin fibers using said reducing composition.
(FR)
L'invention concerne une composition réductrice comprenant (a) au moins un agent réducteur contenant du soufre; (b) au moins un polymère non associatif anionique; et c) au moins un cyclopolymère cationique ayant au moins une structure cyclique dans le squelette du polymère et au moins un groupe ammonium quaternaire comprenant au moins un groupe hydrocarbure en C8-C30. L'invention concerne également un procédé de déformation permanente de fibres de kératine à l'aide de ladite composition réductrice.
