Abstract:
The subject of the present invention is a process for bleaching keratin fibres consisting in applying to said fibres a bleaching composition resulting from the mixing: —of at least one anhydrous composition A comprising at least one peroxygenated salt, —of at least one aqueous composition B comprising at least one basifying agent, and —of at least one composition C comprising at least one oxidizing agent and at least 3% by weight of fatty substance relative to the total weight of the composition C, said bleaching composition comprising at least 10% by weight of fatty substance.
Abstract:
The present invention relates to an aqueous oxidizing composition for treating keratin fibers, comprising: —at least one oxidizing agent; —at least 40% by weight of at least one oil; —at least one phosphoric acid mineral salt; —the pH of the oxidizing composition being less than or equal to 5. The composition in accordance with the invention may be used for dyeing, bleaching or permanently reshaping keratin fibers. It produces ready-to-use compositions that give good dyeing, bleaching or permanent reshaping properties without degrading the keratin fibers and without impairing their cosmetic properties. Furthermore, the composition in accordance with the invention shows good stability over time, especially to storage at high temperatures, for example of about 45° C.
Abstract:
The invention relates to a composition for dyeing human keratin fibers such as the hair, in foam form, comprising at least one alkaline agent, at least one oxidizing agent, at least one oxidation dye precursor and at least one nonionic surfactant of formula (I) R—0—(CH2—CH2—0)n—H (I) in which R represents a linear or branched C10-C18 alkyl or alkenyl radical, n represents a number ranging from 10 to 15. The invention also relates to a process for dyeing human keratin fibers using this composition. A subject of the invention is also a device for dyeing keratin fibers, comprising the composition of the invention in liquid form and a foam dispenser for delivering the composition in the form of a foam.
Abstract:
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.
