Title
(EN) PROCESS FOR DYEING KERATIN FIBRES USING A MONOSACCHARIDE, A POLYSACCHARIDE BEARING AMINE GROUPS AND A DYESTUFF
(FR) PROCÉDÉ DE COLORATION DE FIBRES DE KÉRATINE PAR L'UTILISATION D'UN MONOSACCHARIDE, D'UN POLYSACCHARIDE PORTANT DES GROUPES AMINE ET D'UN COLORANT
Abstract
(EN)
The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising the application to said keratin fibres a) of at least one monosaccharide, b) of at least one particular polysaccharide, in salified or non-salified form, and c) of at least one dyestuff, followed by a heat treatment of the keratin fibres. The present invention also relates to a composition at acidic pH (C) comprising a) at least one monosaccharide, b) at least one polysaccharide bearing amine group(s), in salified or non-salified form, and c) at least one dyestuff. The present invention also relates to a kit comprising a multi-compartment device containing a) at least one monosaccharide, b) at least one polysaccharide bearing amine group(s), and c) at least one dyestuff, and to a device for heating keratin fibres.
(FR)
La présente invention concerne un procédé de coloration de fibres de kératine, en particulier des fibres de kératine humaines telles que les cheveux, comprenant l'application sur lesdites fibres de kératine a) d'au moins un monosaccharide, b) d'au moins un polysaccharide particulier, sous forme salifiée ou non, et c) d'au moins un colorant, suivie d'un traitement thermique des fibres de kératine. La présente invention concerne également une composition à pH acide (C) comprenant a) au moins un monosaccharide, b) au moins un polysaccharide portant un ou des groupes amine, sous forme salifiée ou non, et c) au moins un colorant. La présente invention concerne également un kit comprenant un dispositif à plusieurs compartiments contenant a) au moins un monosaccharide, b) au moins un polysaccharide portant un ou des groupes amine, et c) au moins un colorant, et un dispositif de chauffage des fibres de kératine.
