    摘要: Agents for the reductive decolorization of dyed keratin fibers contain, in a cosmetic carrier, (a) at least one compound of formula (I), A[(CR1R2)SO2M]p,q (I), in which A represents N(R3)3-q or O(R4)2-p, R1, R2, R4 represent a hydrogen atom or a C1-C6 alkyl group, R3 represents residues selected from the group of a hydrogen atom, a C1-C20 alkyl group, a C3-C8 cycloalkyl group optionally substituted with one to three C1-C4 alkyl residues, M represents residues selected from a hydrogen atom or an equivalent of an alkali metal ion, alkaline-earth metal ion, or metal ion, p represents 1 or 2, q represents 1, 2, or 3, wherein at least one of R1, R2, R4 represents a C1-C6 alkyl group if A represents O(R42-p), and R3 does not represent a hydrogen atom if q equals 1, and (b) optionally at least one compound of formula (II), A[(CR1R2)SO3M]p,q (II).

    摘要: Products for oxidatively changing the color of keratinic fibers include at least two preparations (A) and (B), which are produced separately from one another. The first preparation (A) includes, in a cosmetic carrier, (A1) hydrogen peroxide and (A2) at least one chelating agent chosen from a group of specific chelating agents. The second preparation (B) includes, in a cosmetic carrier, (B1) at least one alkalizing agent. The preparation (A) is produced in a first container (container A). The first container includes at least two layers: an inner layer that includes a layer of a synthetic polymer (I) and an outer layer that includes a metal layer. Preparation (B) is produced in a second container (container B), which includes at least two layers: an inner layer that includes a layer of a synthetic polymer (I) and an outer layer that includes a metal layer.

    摘要: The present invention relates to a process for dyeing or lightening keratin fibres, 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 fibres; 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 fibres 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 fibres in a noteworthy manner.
