Title (EN) USE OF O-GLYCOSYLATED INDOLE OR INDOLINE DERIVATIVE WITH GLYCOSIDASE FOR DEYING KERATIN FIBERS
(FR) UTILISATION D'UN DÉRIVÉ D'INDOLE OU D'INDOLINE O-GLYCOSYLÉ AVEC UNE GLYCOSIDASE POUR COLORER DES FIBRES DE KÉRATINE
Abstract:
(EN) A subject of the invention is the use of i) hydroxyindol(in)e derivative(s) glycosylated on at least one hydroxyl group, in the presence of at least ii) one enzyme with glycosidase activity, in particular beta-glycosidase activity, more particularly glucosidase activity and even more particularly beta-glucosidase activity, for treating keratin fibres, in particular dyeing human keratin fibres such as the hair, preferably dyeing said fibres. A subject of the invention is also a process for treating keratin fibres using i), ii) and a kit comprising the ingredients i) and ii). The process according to the invention has the advantage of dyeing human keratin fibres, with powerful or chromatic dyeing results that are resistant to washing, perspiration, sebum andlight, and that are moreover long-lasting, without impairing said fibres. Furthermore, the colourations obtained from the process give uniform colours from the root to the tip of a fibre (low colouration selectivity). In addition, the compositions comprising the i) hydroxyindol(in)e derivative(s) glycosylated on at least one of the hydroxyl groups degrade very little in air and remain stable with respect to storage.
(FR) Un objet de la présente invention est l'utilisation de i) dérivé(s) d'hydroxyindol(in)e glycosylé(s) sur au moins un groupe hydroxyle, en présence d'au moins ii) une enzyme ayant une activité glycosidase, en particulier une activité bêta-glycosidase, plus particulièrement une activité glucosidase et encore plus particulièrement une activité bêta-glucosidase, pour le traitement de fibres de kératine, en particulier la coloration de fibres de kératine humaines telles que des cheveux, de préférence la coloration desdites fibres. Un objet de l'invention est en outre un procédé de traitement de fibres de kératine au moyen de i), ii) et un kit comprenant les composants i) et ii). Le procédé selon l'invention présente l'avantage de colorer des fibres de kératine humaines, avec des résultats de coloration puissants ou chromatiques qui sont résistants au lavage, la transpiration, le sébum et la lumière, et qui sont en outre durables, sans altérer lesdites fibres. En outre, les colorations obtenues au moyen du procédé donnent des couleurs uniformes de la racine à la pointe d'une fibre (faible sélectivité de coloration). En outre, les compositions comprenant i) le(s) dérivé(s) d'hydroxyindol(in)e glycosylé(s) sur au moins un des groupes hydroxyle se dégradent très peu dans l'air et restent stables à la conservation.
