Description

Title of the invention: Composition comprising a (bi)carbonate, a silicate and a fatty substance in a particular proportion

[0001] The present invention relates to a composition, in particular a composition for lightening keratin fibers, and in particular human keratin fibers such as hair, comprising one or more (bi)carbonate(s), one or more silicate(s) and one or more fatty substances in a particular content.

[0002] The invention also relates to a method for lightening human keratin fibers using such a composition.

[0003] In the field of hair lightening, tone level is generally used to characterize the degree or level of lightening. The concept of "tone" is based on the classification of natural shades, with one tone separating each shade from the one immediately preceding or following it. This definition and the classification of natural shades are well known to hairdressing professionals and are published in the book "Sciences des traitements cheveux" by Charles ZVIAK, 1988, Ed. Masson, pp. 215 and 278.

[0004] The tone heights range from 1 (black) to 10 (light blonde), one unit corresponding to one tone; the higher the number, the lighter the shade.

[0005] Lightening thus makes it possible to bring a tone height lighter than the initial natural tone height of the hair.

[0006] The processes used to lighten hair generally consist of using an aqueous composition comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority of cases.

[0007] The role of this oxidizing agent is to degrade the melanin in the hair, which, depending on the nature of the oxidizing agent present, leads to a more or less pronounced lightening of the hair fibers. Thus, for relatively slight lightening, the oxidizing agent is generally hydrogen peroxide. When greater lightening is desired, particularly lightening of at least 5 shades, peroxide salts, such as persulfates, are usually used in the presence of hydrogen peroxide. These peroxide salts are contained in compositions which, at the time of use, are mixed with an aqueous composition including hydrogen peroxide. However, the lightening obtained by such a combination is not always satisfactory because it results in hair with unattractive yellow / orange tones, which complicates subsequent coloring by limiting it to achieving warm tones.

[0008] In order to adjust the pH of the compositions to an alkaline pH to allow the activation of the oxidizing agent, an alkaline agent is used. This alkaline agent also causes swelling of the keratin fiber, with an opening of the scales, which promotes the penetration of the oxidizing agent into the fiber, and thus increases the efficiency of the reaction.

[0009] However, the use of alkaline agents and peroxide salts can lead to a deterioration in hair quality. The main causes of this deterioration are a decrease in cosmetic properties, such as shine, and a degradation of mechanical properties, particularly a reduction in mechanical resistance, which can also result in increased porosity. The hair is weakened and can become brittle during subsequent treatments such as blow-drying. An increase in frizz, which is unsightly, is also observed.

[0010] Lightening dark hair is therefore particularly delicate because it requires the use of a large amount of peroxygenated salts if one wishes to lighten them strongly, which can weaken them.

[0011] In addition, lightening compositions applied to very curly hair tend to alter the shape of the curls, which generally have a less defined appearance.

[0012] Furthermore, compositions containing peroxygenated salts are generally in powder form. However, since powdered compositions have the disadvantage of producing dust during handling, transport, and storage, paste-like compositions have been proposed. The powdered compounds are thus dispersed in a thickened, inert, organic liquid support, which provides a solution to the volatility problems.

[0013] On the other hand, the implementation of compositions in paste form causes new difficulties.

[0014] These pastes are generally anhydrous and have a compact, hard texture. Consequently, mixing the paste with the hydrogen peroxide composition is far from easy. This results not only in a longer mixing time but also in difficulties in obtaining a homogeneous and stable mixture.

[0015] Furthermore, the lightening compositions obtained may be difficult to distribute evenly over the entire head of hair, particularly curly or frizzy hair, which may lead to undesirable uneven lightening performance.

[0016] Furthermore, persulfate-based compositions are generally not chemically compatible with the presence of oxidation dyes and / or direct dyes to be able to bleach and color the hair fiber in a single step step. Thus, when it is desired to simultaneously bleach and color keratin fibers, a two-step process is generally used with a first step of bleaching the keratin fibers followed by a second step of coloring the keratin fibers using a coloring composition comprising one or more direct dyes and / or one or more oxidation dyes.

[0017] Finally, the formulation of environmentally friendly cosmetic products, that is to say whose design and development take into account environmental issues, is becoming a major concern to help meet planetary challenges.

[0018] It is therefore essential to propose more sustainable compositions that make it possible to respond to these environmental challenges.

[0019] Thus, one of the objectives of the present invention is to provide a composition that allows for the effective lightening of keratin fibers, particularly dark keratin fibers, with improved neutralization of yellow and / or orange tones. Such a composition should also be more respectful of fiber quality, notably by minimizing degradation, and exhibit excellent performance characteristics, particularly by being easy to mix with an aqueous hydrogen peroxide composition before use, the resulting mixture also being easy to apply to the keratin fibers.

[0020] Finally, such a composition must also be compatible with the presence of direct and / or oxidation dyes in order to obtain good color development, natural shades with chromatic reflections and also to allow a wider range of colors to be achieved.

[0021] This objective and others are achieved by the present invention, which therefore relates to a composition comprising: - one or more compounds C chosen from (bi)carbonates, (bi)carbonate generating systems, and their mixtures, preferably from carbonates, bicarbonates, and their mixtures; - one or more silicates; and - one or more fats in a total content exceeding 10% by weight relative to the total weight of the composition.

[0022] According to a preferred embodiment, the composition according to the invention is a keratin fiber lightening composition, preferably human, preferably hair.

[0023] The invention also relates to a lightening method employing said composition, the use of the composition for lightening keratin fibers, and in particular hair, as well as a device for several compartments, suitable for the implementation of said lightening composition.

[0024] The composition according to the invention makes it possible to obtain effective lightening of keratin fibers, without major alteration of the cosmetic properties of the hair, with improved qualities of use.

[0025] In particular, the composition according to the invention makes it possible to obtain effective lightening of keratin fibers with a more neutralized (less yellow) and more natural result.

[0026] The composition according to the invention mixes quickly and easily with an aqueous hydrogen peroxide composition to obtain a homogeneous and stable mixture. The resulting mixture is easily applied to the hair. Its smooth, creamy consistency helps prevent dripping during application while spreading easily throughout the hair, even in very curly hair. Furthermore, the mixture does not dry out during the application time, ensuring optimal availability of the active ingredients throughout the entire application period. In addition, the mixture rinses out easily.

[0027] The cosmetic properties of hair treated with the composition according to the invention do not show any major alteration, particularly in terms of softness and detangling. The composition specifically conditions the hair and reduces breakage during detangling, especially in very curly hair. When applied to very curly hair, it also helps maintain curl shape by providing good definition. The composition also provides good frizz control.

Fatty body

Solid fats are defined as fats having a melting point above 25°C at atmospheric pressure (1.013 x 10⁵ Pa).

[0071] For the purposes of the present invention, the melting point corresponds to the temperature of the most endothermic peak observed in thermal analysis (differential scanning calorimetry or DSC) as described in ISO 11357-3; 1999. The melting point can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name "MDSC 2920" by TA Instruments.
