Definitions

  • Kit for dyeing and/or bleaching keratin fibers comprising an alkaline agent, an oxidizing agent, and an openable and closable airtight container
  • the present invention relates to a process for dyeing the hair, in mousse form, using a composition comprising oxidation dye precursors, and to a composition in mousse form.
  • oxidation dyeing or permanent dyeing. More particularly, this dyeing method uses one or more oxidation dyes, usually one or more oxidation bases optionally combined with one or more couplers.
  • oxidation bases are chosen from ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, can give access to coloured species.
  • the shades obtained with these oxidation bases are often varied by combining them with one or more couplers, these couplers being chosen especially from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds.
  • Permanent dyeing processes thus consist in using with the dye composition an aqueous composition comprising at least one oxidizing agent such as hydrogen peroxide, under alkaline pH conditions in the vast majority of cases.
  • the alkaline agent conventionally used is aqueous ammonia or other alkaline agents, such as alkanolamines.
  • Dye compositions may be in various forms, such as lotions, gels, emulsions, creams or mousses.
  • Colouring mousses or foams are pleasant to use, but they often lack of grey hair coverage and have poor fastness over time. Rapid disappearance of the mousse after application or non-uniform application along the fibres may be observed, for example.
  • Coloring mousses to be formed in shaker have been proposed but quality and quantity of the mousse is not sufficient.
  • kits for dyeing and/or bleaching human keratin fibers, such as the hair comprising :
  • mixture of the first and second composition comprises a total amount of surfactants of at least 4% by weight, relative to the total weight of said mixture.
  • the invention also relates to a process for dyeing and/or bleaching human keratin fibres using this kit.

  • mixture of the first and second composition comprises a total amount of surfactants of at least 4% by weight, relative to the total weight of said mixture
  • the first and second compositions of the invention are stirred and form an homogeneous and copious foam that is easy to take from the container, and particularly pleasant to apply. It has a light, airy texture, which makes it particularly pleasant to use.
  • the qualities of the mousse are sufficiently long-lasting to enable uniform application of the dye product, without running.
  • the resulting foam composition makes it possible to conserve particularly efficient dyeing properties such as the colour strength, intensity, the resistance to external agents (shampoos, perspiration, light) and the selectivity.
  • the human keratin fibers treated via the process according to the invention are preferably the hair.
  • the first composition contains at least one dye precursor and/or at least one direct dye, preferably at least one dye precursor.
  • the first composition comprises one or more alkaline agent(s).
