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 alcohol, and at least one compound selected from organic acids, amphoteric or zwitterionic compounds, esters and / or amides and / or imines, organic amines, alkanes and / or alkenes and / or ethers and mixtures thereof, and further to a method for lightening keratin fibers using said composition.

Background Art

[0002] When a person desires to change the color of their hair, especially when they desire 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 in terms of the "tone gradation" that characterizes the degree or extent of lightening. The concept of "tone" is based on classifying natural colors, and each tone separates each color from the colors immediately before and after it. This definition and classification of natural colors are known to hair styling professionals and are published as a book (Non-Patent Document 1).

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

[0004] In most cases, it is a known practice to lighten or decolorize hair using a brightening composition or a decolorizing composition containing at least one chemical oxidizing agent under alkaline pH conditions. The role of this oxidizing agent is to decompose the melanin in the hair, thereby resulting in a lightening of the visible fibers, although to varying degrees depending on the nature of the oxidizing agent present and the pH conditions. Thus, in the case of relatively mild lightening, the oxidizing agent is generally hydrogen peroxide. When stronger lightening is desired, especially when the hair to be treated is dark in color, persulfate is usually used in the presence of hydrogen peroxide. However, the lightening obtained by the action of such a combination turns the hair into an unattractive yellowish orange hue far from the natural color, thereby complicating subsequent dyeing as it is limited to producing warm-toned colors, and is not always satisfactory. Furthermore, persulfate-based brightening compositions may reduce the quality of the fibers. Additionally, persulfate-based compositions generally lack 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 that involves 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.

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.

[0127] 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 called the "semi-dry" method.
