The thickener or gelling effect is conventionally obtained with conventional thickening agents such as cellulose derivatives, starch derivatives, alginates, thickener silicas or mixtures of judiciously selected surfactants. When these traditional thickeners are used, however, a significant decrease in the viscosity of the final decolorizing composition is observed over time. Thus, there is a need for a thickening system capable of ensuring the maintenance of a high viscosity for the time necessary to obtain the desired discoloration, generally comprised between ten minutes and one hour. The applicant has surprisingly discovered that it is possible to considerably improve the maintenance of the viscosity, as time passes, of the discoloration compositions described above, by associating with the initial system, a nonionic and / or anionic amphiphilic polymer comprising a fatty chain. In the same way, it is found that such a thickener system allows diluting, with the aqueous hydrogen peroxide compositions, clearly more important than the known thickener systems.
