Definitions

  • TITLE Process for bleaching keratin fibres, comprising the application of a bleaching composition and the application of a composition comprising at least one alkaline agent and which is free of peroxygenated salts
  • the present invention relates to a process for bleaching keratin fibres, in particular human keratin fibres such as the hair, comprising the application of a particular bleaching composition, and the application of a composition comprising at least one alkaline agent and which is free of peroxygenated salts.
  • tone height is generally used to characterize the degree or level of lightening.
  • tone is based on the classification of natural shades, one tone separating each shade from the shade immediately following or preceding it. This definition and the classification of natural shades are well known to hairstyling professionals and are published in the book Sciences des.s capillaires [The Science of Hair Care] by Charles Zviak, 1988, published by Masson, pages 215 and 278.
  • the tone heights range from 1 (black) to 10 (very light blond), one unit corresponding to one tone; the higher the figure, the lighter the shade.
  • Lightening thus allows the head of hair to be given a lighter tone height than its original natural tone.
  • the processes used for lightening the hair generally consist in using an aqueous composition comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority of cases.
  • This oxidizing agent has the role of degrading the melanin of the hair, which, depending on the nature of the oxidizing agent present, leads to more or less pronounced lightening of the fibres.
  • the oxidizing agent is generally hydrogen peroxide.
  • peroxygenated salts for instance persulfates
  • these peroxygenated salts are contained in compositions which, at the time of use, are mixed with an aqueous composition comprising hydrogen peroxide.
  • an alkaline agent is used in order to adjust the pH of the compositions to an alkaline pH to allow activation of the oxidizing agent. This alkaline agent also causes swelling of the keratin fibres, with opening of the scales, which promotes penetration of the oxidizing agent into the fibre, and thus increases the efficacy of the reaction.
  • alkaline agents and peroxygenated salts may impair the quality of the hair.
  • the essential causes of this deterioration in hair quality are a reduction in its cosmetic properties, such as sheen, and a deterioration in its mechanical properties, more particularly a deterioration in its mechanical strength, which may also be reflected by an increase in its porosity.
  • the hair is weakened and may become brittle during subsequent treatments such as blow-drying.
  • the lightening of dark hair is particularly difficult because it requires the use of a large amount of peroxygenated salts if the hair is to be lightened significantly, and/or an increase in the application time of the bleaching compositions to the hair, which may weaken it.
  • this process does not necessarily provide optimum lightening and good neutralization of yellow and/or orange tints.
  • one of the objectives of the present invention is to propose a process for bleaching keratin fibres, in particular human keratin fibres such as the hair, which does not have the drawbacks mentioned above, i.e. which affords effective lightening of keratin fibres, notably dark keratin fibres, with improved neutralization of yellow and/or orange tints without impairing the cosmetic and/or mechanical properties of the hair.
  • the present invention relates to a process for bleaching keratin fibres, in particular human keratin fibres such as the hair, comprising, in sequence: a) the application to said keratin fibres of at least one composition C comprising: i) at least one alkaline agent AA1; ii) at least one peroxygenated salt SI; and iii) hydrogen peroxide; and b) the application to said keratin fibres of at least one composition F comprising: i) at least one alkaline agent AA2; ii) optionally hydrogen peroxide, and in which composition F is free of peroxygenated salts, it being understood that step a) may be followed by step b) or step a) may be preceded by step b): preferably, step a) is followed by step b).
  • the process according to the invention affords improved lightening of the keratin fibres and also improved neutralization of the yellow and/or orange tints of said fibres.
  • the expression “greater than” and, respectively, the term “less than” refer to an open range which is strictly greater, or, respectively, strictly less, and thus that the limits are not included.
  • keratin fibres particularly means human keratin fibres such as head hair, eyelashes, eyebrows, and bodily hair, preferentially head hair, eyebrows and eyelashes, even more preferentially head hair.
  • the term “the hair” means head hair. This term does not correspond to bodily hairs, the eyebrows or the eyelashes.
