Description

Technical Field

[0001] The present invention relates to a composition for lightening keratin fibers, comprising at least one chemical oxidizing agent, at least one (bi) carbonate, at least one silicate, at least one organic acid, an alcohol, an amphoteric or zwitterionic compound, an ester, and / or an amide, and / or an imine, an organic amine, an alkane, and / or an alkene, and / or an ether and at least one compound selected from mixtures thereof, and also to a method for lightening keratin fibers using said composition.

Background Art

[0002] When a person wishes to change the color of their hair, especially when they wish to obtain a lighter color than the original color, it is often necessary to first lighten or decolorize the hair. To do this, products for lightening or decolorizing are used. The lightening of hair is evaluated in terms of a "shade scale" that characterizes the degree or extent of lightening. The concept of "shade" is based on grading natural shades and differentiates the shade immediately before or after by one shade. This definition and grading of natural colors is well known to hair styling professionals and is published in a book (Non-Patent Document 1).

[0003] The shade scale is divided into levels from 1 (black) to 10 (very light blonde), with 1 unit corresponding to one shade level, and the larger the number, the lighter the color.

[0004] In many cases, a method for lightening or decolorizing hair with a lightening or decolorizing composition containing at least one chemical oxidizing agent under alkaline pH conditions is known. The role of this oxidizing agent is to decompose the melanin in the hair, and as a result, the fiber is lightened (although there are differences in degree depending on the nature of the oxidizing agent present and the pH conditions). Therefore, in the case of relatively gentle lightening, the oxidizing agent is generally hydrogen peroxide. When more lightening is desired, especially when the hair to be treated is dark, persulfate is usually used in the presence of hydrogen peroxide. However, the lightening obtained by the action of such a combination makes the hair an orange-yellow color that is quite different from the natural color and not very attractive, thereby complicating the subsequent coloring by limiting it to obtaining warm-toned colors. Therefore, it is not always satisfactory. Furthermore, persulfate-based lightening compositions can cause deterioration of the fiber quality. In addition, persulfate-based compositions generally do not have chemical compatibility with the presence of oxidation dyes and / or direct dyes for enabling the decolorization and dyeing of hair fibers in a single step. Therefore, when it is desired to simultaneously decolorize and dye keratin fibers, a two-step method is used, which includes a first step of decolorizing the keratin fibers, followed by a second step of dyeing the keratin fibers using a dye composition containing one or more direct dyes and / or one or more oxidation dyes.

[0083] In the oxidation method, a single phthalocyanine or a mixture of phthalocyanines, such as a mixture of cobalt phthalocyanine and iron phthalocyanine, can be used as a catalyst. The amount of the catalyst depends on the desired degree of substitution. Generally, a small amount, for example, an amount corresponding to 0.003 to 0.016 molar equivalent per 100 glucose units of the polysaccharide, is suitable.

[0084] This method can also be carried out by contacting the powdered polysaccharide with a catalyst and peroxide dissolved in a small amount of water. This method is referred to as the "semi-dry" method.

[0085] This method can also be carried out by reactive extrusion in the presence of peroxide.

[0088] According to one embodiment, the polysaccharide is obtained by the oxidation of inulin by performing a reactive extrusion method in the presence of hydrogen peroxide.

[0089] The weight average molecular weight of the polysaccharide chain before and after oxidation is preferably in the range of 400 to 15,000,000, more preferably 500 to 10,000,000, and more particularly 500 to 50,000 g / mol.

[0090] The most particularly preferred polysaccharide in the present invention corresponds to formula (II) (wherein P represents a polymer chain derived from inulin or starch; m is a value such that the degree of substitution of the polysaccharide with one or more aldehyde groups (DS(CHO)) is included in the range of 0.005 to 2.5; n is a value such that the degree of substitution of the polysaccharide with one or more carboxyl groups (DS(COOX)) is included in the range of 0.001 to 2).
