    • The present invention relates to a process for dyeing or lightening keratin fibers, comprising the step of extemporaneously mixing at the time of use two compositions (A) and (B) and of applying the said mixture to the said fibers; the said mixture comprising at least 25% by weight of fatty substances relative to the total weight of the composition obtained from the mixing of two compositions (A)+(B); with: —(A) representing a composition in direct emulsion form whose content of oil(s) ii) is at least 30% by weight relative to the weight of composition (A), and comprising: i) at least one nonionic surfactant that is solid at room temperature and at atmospheric pressure, with an HLB ranging from 1.5 to 10; ii) at least one basifying agent; Hi) optionally at least one additional surfactant other than the solid nonionic surfactants (i), iv) optionally at least one dye; and —(B) representing a composition comprising at least one chemical oxidizing agent. A subject of the present invention is also a multi-compartment device and a composition (A) in direct emulsion form and the ready-to-use composition resulting from the mixing of compositions (A) and (B). The process according to the invention makes it possible to dye keratin fibers in a powerful, intense and/or homogeneous manner while at the same time being easy to prepare and to apply, since the mixture in the form of an oil-rich emulsion does not run, but remains localized at the point of application. The process of the invention also makes it possible to lighten keratin fibers in a noteworthy manner.
    • 本发明涉及一种染色或减轻角蛋白纤维的方法,包括在使用时将两种组合物(A)和(B)即时混合并将所述混合物施用于所述纤维的步骤; 所述混合物包含相对于由两种组合物(A)+(B)的混合物获得的组合物的总重量的至少25重量%的脂肪物质; 具有: - (A)代表直接乳液形式的组合物,其中油的含量ii)相对于组合物(A)的重量为至少30重量%,并且包含:i)至少一种非离子表面活性剂, 在室温和大气压下为固体,HLB为1.5至10; ii)至少一种碱化剂; Hi)任选地至少一种除固体非离子表面活性剂(i)外的另外的表面活性剂,iv)任选的至少一种染料; 和 - (B)代表包含至少一种化学氧化剂的组合物。 本发明的主题还是多室装置和直接乳液形式的组合物(A)和由组合物(A)和(B)混合得到的即用组合物。 根据本发明的方法使得可以以强大,强烈和/或均匀的方式染色角蛋白纤维,同时易于制备和应用,因为富含油的乳液形式的混合物不 运行,但在应用点保持本地化。 本发明的方法还使得可以以显着的方式减轻角蛋白纤维。
