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 amine, and at least one compound selected from alcohols, amphoteric or zwitterionic compounds, esters and / or amides and / or imines, organic acids, alkanes and / or alkenes and / or ethers, and mixtures thereof, and also relates to a method for lightening keratin fibers using the above composition.

Background Art

[0002] When a person desires to change the color of their hair, especially when desiring to obtain a lighter color than the original color, it is often necessary to first lighten or decolorize the hair. To do this, lightening or decolorizing products are used. The lightening of hair is evaluated by the "tone depth" which characterizes the degree or level of lightening. The concept of "tone" is based on classifying natural hues, and one tone distinguishes each hue from the hue before or after it. This definition and classification of natural hues are well-known to those skilled in hair styling and are published as a book (Non-Patent Document 1).

[0003] The tone level ranges from 1 (black) to 10 (very light blonde), with one unit corresponding to one tone, and the larger the number, the lighter the hue.

[0004] The use of a lightening or decoloring composition containing at least one chemical oxidizing agent for lightening or decoloring hair is a known technique, which is mostly carried out under alkaline pH conditions. The role of this oxidizing agent is to decompose the melanin in the hair, and as a result (although there are differences in degree depending on the nature of the oxidizing agent present and the pH conditions), the fiber is lightened. Therefore, in the case of relatively gentle lightening, the oxidizing agent is generally hydrogen peroxide. When higher 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 unattractive yellowish-orange color far from the natural color, and as a result, subsequent dyeing becomes complicated because it is limited to producing warm-colored tones, so it is not always satisfactory. Furthermore, persulfate-based lightening compositions can cause a decrease in the quality of the fiber. Moreover, persulfate-based compositions generally do not have chemical compatibility with the presence of oxidative 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 uses 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 oxidative dyes.

Chemical formula

[0186] The expression "degree of substitution DS(CHO) or DS(COOX) of the polysaccharide of the present invention" means the ratio of the number of carbon atoms oxidized to obtain aldehyde groups or carboxyl groups in all repeating units to the number of monosaccharides that are elements of the polysaccharide (including those ring-opened by preliminary oxidation).

[0187] The groups CHO and COOX can be obtained at the C2, C3, or C6 position of a sugar unit containing, for example, six carbon atoms during the oxidation of a specific carbon atom. Preferably, the oxidation occurs at the C2 and C3 positions, and more specifically, it can occur at 0.01% to 75%, preferably 0.1% to 50%, based on the number of rings that could potentially be opened.

[0188] The polysaccharide chain represented by P is preferably selected from inulin, cellulose, starch, guar gum, xanthan gum, pullulan gum, alginate gum, agar gum, carrageenan gum, gellan gum, acacia gum, xylose and tragacanth gum, and derivatives thereof, cellobiose, maltodextrin, scleroglucan, chitosan, ulvan, fucoidan, alginate, pectin, heparin, hyaluronic acid or mixtures thereof, more preferably selected from inulin or starch. Even more preferably, the polysaccharide chain is inulin.

[0189] The term "derivative" means a compound obtained from a chemical modification of the aforementioned compounds. They may be esters, amides, or ethers of the said compounds.

[0190] The oxidation can be carried out by methods known in the art, for example, by the methods described in French Patent No. 2842200, French Patent No. 2854161, or the paper "Hydrophobic films from maize bran hemicelluloses", by E. Fredon et al., Carbohydrate Polymers 49, 2002, pages 1 - 12. Another oxidation method is described in the paper "Water soluble oxidized starches by peroxide reaction extrusion", Industrial Crops and Products 75 (1997) 45 - 52 - R.E. Wing, J.L. Willet. These oxidation methods are easy to implement, efficient, and do not produce toxic by - products or by - products that are difficult to remove.

[0191] The peroxides that can be used during these oxidation methods may be alkali metal or alkaline earth metal percarbonates or perborates, alkyl peroxides, peracetic acid, or hydrogen peroxide. Hydrogen peroxide is particularly preferred insofar as it is readily available and does not produce interfering by-products.

[0192] The amount of peroxide in the reaction medium is 0.05 to 1 molar equivalent, preferably 0.1 to 0.8 molar equivalent, per glucose unit of the polysaccharide. It is preferred to add the peroxide in several portions sequentially while stirring the reaction medium between additions.

[0193] During the oxidation method, one type of phthalocyanine, or a mixture of phthalocyanines, for example, a mixture of cobalt phthalocyanine and iron phthalocyanine, may be used as a catalyst. The amount of 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.

[0194] This method can also be carried out by contacting the powdered polysaccharide with a catalyst dissolved in a small amount of water and a peroxide. This method is referred to as the "semi-dry" method.

[0195] This method can also be carried out by reactive extrusion in the presence of a peroxide.

[0197] More preferably, the polysaccharide is obtained by oxidation of inulin or starch, and even more preferably by oxidation of inulin.

[0198] According to one embodiment, the polysaccharide is obtained by oxidation of inulin by performing a reactive extrusion method in the presence of hydrogen peroxide.
