Description

Title of the invention: Method for stripping artificial color from keratin fibers using several types of peroxygen compounds, a composition and a kit

[0001] The present invention relates to the field of cosmetic treatment of keratin fibers, preferably hair. It thus aims to propose new methods for stripping artificial color from keratin fibers comprising, firstly, the preparation of a stripping composition M based on peroxygenated compounds, then, secondly, the application of the stripping composition M to the keratin fibers previously artificially colored.

[0002] More specifically, the present invention relates to a process for stripping artificial color from keratin fibers such as hair, comprising at least one step (i) of preparing a composition M, comprising at least the extemporaneous mixture of a composition A comprising at least one first peroxygen compound PI chosen from persulfates, perborates, percarbonates, their salts and their mixtures, at least one second peroxygen compound P2 different from persulfates, perborates and percarbonates, and at least one alkaline agent, with a composition B, distinct from composition A, comprising at least one cationic surfactant and at least one non-silicone fatty substance, then a step (ii) of applying said composition M to the keratin fibers.

[0003] For a long time, many people have been looking to change the color of their hair, and in particular to hide their gray hair.

[0004] It is known to dye keratin fibers, in particular human keratin fibers such as hair, to obtain so-called "permanent" colorations with dye compositions containing oxidation dye precursors, generally called oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolo-pyridines. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, can give rise to colored compounds by an oxidative condensation process.

[0005] It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or color modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indole or pyridine compounds. The variety of molecules involved at the oxidation bases and couplers, allows the production of a rich palette of colors.

[0006] Another type of coloring is so-called semi-permanent coloring or direct coloring, which consists of applying direct dyes to the keratin fibers, which are colored and coloring molecules having an affinity for said fibers, leaving them to stand, then rinsing them.

[0007] In order to achieve these colorations, the direct dyes generally used are chosen from nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane direct dyes, and natural dyes.

[0008] To vary the shades obtained in oxidation coloring, or to enrich them with reflections, oxidation dyes can be used in association with direct dyes.

[0009] By "direct dye" we mean natural and / or synthetic dyes, different from oxidation dyes. These are dyes which will diffuse superficially on the fiber and color the fibers by themselves.

[0010] The direct dye(s) may be natural or synthetic, cationic, anionic or non-ionic direct dyes.

[0011] By "natural dyes", or "of natural origin" we mean dyes derived from natural materials (plant, mineral or animal origin) such as, for example, extracts, ground materials, decoctions, and more or less concentrated in dyes.

[0012] Among natural dyes are included compounds which may be present in nature and which are reproduced by chemical (hemi)synthesis. Natural colorants may in particular be chosen from spinulosin, orceins, polyphenols or orthodiphenols (also called ODPs in the remainder of the description) and all extracts rich in ODPs, curcumin, indole derivatives such as isatin or indole-2,3-dione, indigoids including indigo, phthalocyanines and porphyrins in particular complexed with a metal, glycosylated or non-glycosylated iridoids, chromenic colorants, anthraquinone and naphthoquinone colorants such as lawsone or henna, juglone, spinulosin, chromenic or chromic colorants, such as neoflavanols and neoflavanones, flavanols; and anthocyanidols.Extracts or decoctions containing these natural dyes can also be used, particularly poultices or plant extracts containing said dyes.

[0013] For various reasons, such as the desire to partially or totally modulate the shade thus conferred on the hair by an oxidation dye or a direct dye, in particular a direct dye based on natural dyes such as those described above, or even the desire to eliminate this coloring, one may be led to want to partially or totally remove the dyes thus formed or brought into or on the hair. The artificial color is then stripped from the keratin fibers.

[0014] By “artificial color” is meant a color obtained by at least one of the types of coloring described above.

[0015] This stripping is generally carried out via processes using oxidizing or reducing systems, for example peroxygen reagents or ammonia.

[0016] However, the stripping techniques of the prior art which use powders of peroxygenated reagents such as ammonium or alkali metal perborates or percarbonates, which are combined at the time of use with an aqueous composition of hydrogen peroxide, are often very aggressive and modify the chemical structure of the keratin.

[0017] This results in poor cosmetic properties of the hair such as difficult detangling, an unpleasant feel or rough and dull hair, but above all by a degradation of the keratin fibers.

[0018] This degradation of the fibers is particularly undesirable because it irreversibly deteriorates the physicochemical properties of the hair. The hair becomes more porous and therefore more difficult to dry, it exhibits greater sensitivity to various other hair treatments such as coloring or perming, and its mechanical properties and surface properties are adversely modified, which results, for example, in a reduction in tensile strength or an increase in the coefficient of friction.

[0019] Furthermore, prior art stripping techniques which use reducing systems, for example based on ammonia, can generate a particularly unpleasant odor for the user.

[0020] Furthermore, the application to the hair of the stripping compositions of the prior art is often considered difficult by users. These compositions are often particularly fluid, which can cause splashes and drips on the hair, and thus alter the expected result.

[0021] There therefore remains a real need for methods for stripping artificial color from keratin fibers, in particular hair, which make it possible to obtain effective stripping of the artificial coloring from previously colored keratin fibers, in particular homogeneous stripping for an aesthetic result, which are easy to implement on the keratin fibers to be treated, namely easy to mix, without risk of dripping during application, and without requiring lengthy manual kneading work, which do not generate an unpleasant odor and which make it possible to preserve the integrity of the keratin fibers, while giving the fibers good cosmetic properties such as softness to the touch, shine, flexibility, a smooth feel and ease of disentangling.

[0022] The present invention makes it possible to meet these needs.

[0023] The subject of the present invention is a process, preferably cosmetic, for stripping artificial color from keratin fibers such as hair, comprising at least the following steps: (i) the preparation of a composition M, comprising at least the extemporaneous mixture: a. of a composition A comprising: - at least one first peroxygen compound PI chosen from persulfates, perborates, percarbonates, their salts, and their mixtures, - at least one second peroxygen compound P2, different from persulfates, perborates and percarbonates, and - at least one alkaline agent, with b. a composition B, distinct from composition A, comprising: - at least one cationic surfactant, and - at least one non-silicone fatty substance, and c. optionally an aqueous composition C, distinct from compositions A and B, comprising at least one chemical oxidizing agent; then (ii) the application of said composition M to the keratin fibers.

[0024] The method according to the invention makes it possible to effectively remove artificial color from keratin fibers previously colored using an oxidation coloring and / or direct coloring composition.

[0025] In addition, the keratin fibers treated using this composition exhibit good fiber integrity as well as a good level of conditioning, particularly in terms of detangling, softness, smoothness to the touch, shine and suppleness. The result obtained is homogeneous and aesthetic.

[0026] The stripping composition M according to the invention is particularly easy to apply homogeneously to keratin fibers and does not diffuse an unpleasant odor.

[0027] The invention also relates to an aqueous cosmetic composition for stripping artificial color from keratin fibers such as hair, comprising at least one first peroxygen compound PI chosen from persulfates, perborates, percarbonates, their salts, and their mixtures, at least one second peroxygen compound P2 different from persulfates, perborates and percarbonates, at least one alkaline agent, at least one cationic surfactant, at least one non-silicone fatty substance, and optionally, at least one chemical oxidizing agent different from the peroxygen compounds PI and P2.

[0240] Compositions A1, A2 and B were prepared from the ingredients indicated in the table below, the quantities of which are expressed in % by weight of active material (AM).

[0243] Example 1: A stripping composition Ml according to the invention was prepared by mixing, in a bowl and with a brush, composition Al according to the invention (table 1) with composition B (table 2), according to a weight ratio of 1g of composition Al for 3g of composition B.

[0244] A comparative stripping composition M2 was prepared by mixing, in a bowl and with a brush, the composition Al according to the invention (Table 1) with water, according to the weight ratio of 1g of composition Al to 2.14g of water.

[0245] Each of the stripping compositions M1 and M2 was applied to a lock of Caucasian HT5 hair previously colored with a Majirouge® Carmilane 6.66 coloring at a rate of 10g of composition per 1g of lock.

[0246] Each composition is applied to the entire strand with the help of a brush.

[0247] Each lock of hair is then left for 20 minutes at room temperature in the open air, on plates thermostatically controlled at 33°C. Each lock of hair is then rinsed, then dried with a hairdryer for 2 minutes.

[0248] The stripping of the artificial coloring of the hair strands was then evaluated in the CIE L*a*b* system, using a Minolta Spectrophotometer CM3600A colorimeter (illuminant D65, angle 10°, specular component included).

[0249] In this L*a*b* system, L* represents the color intensity, a* indicates the green / red color axis and b* the blue / yellow color axis.

[0250] The stripping of artificial coloring is evaluated by the color difference AE between the colored strands before stripping, then after having undergone stripping according to the protocol described above. The higher the value of AE, the more the artificial coloring is removed.

[0266] The stripping of artificial coloring according to a method according to the invention comprising the application of composition M3 is better compared to the comparative method comprising the application of composition M4.

[0267] Example 3: A comparative stripping composition M5 was prepared by mixing, in a bowl and with a brush, the non-inventive composition A2 (table 1) with composition B (table 2), according to the weight ratio of 1g of composition A2 to 3g of composition B.

[0268] The comparative stripping composition M5 is compared with the stripping composition M1 according to the invention of example 1 above.

[0269] Each of the stripping compositions M1 and M5 was applied to a lock of Caucasian HT5 hair previously colored with a Majirouge® Carmilane 6.66 coloring.

[0270] Each composition is applied to the entire strand using a brush.

[0271] Each lock of hair is then left for 20 minutes at room temperature in the open air. Each lock of hair is then rinsed and then dried with a hairdryer for 2 minutes.
