Abstract

The present invention relates to a composition comprising at least one compound selected from hyaluronic acids and / or derivatives thereof, and mixtures thereof, at least one (hydrogen) carbonate, at least one fatty acid and at least one dye.

Description

[0001] The present application relates to a composition comprising hyaluronic acid and / or a derivative thereof, at least one carbonate, at least one fatty acid and at least one dye.

[0002] The present application also relates to a process for dyeing keratin fibres, especially the hair, using this composition.

[0003] Finally, the present application relates to the use of such a composition for dyeing keratin fibres and especially the hair.

[0004] Many people have long sought to change the colour of their hair and in particular to mask their grey hair.

[0005] In the field of dyeing keratin fibres, in particular human keratin fibres, it is known practice to dye keratin fibres via various techniques using direct dyes or pigments for non-permanent dyeing, or dye precursors for permanent dyeing.

[0006] Essentially, three types of process for dyeing the hair exist:

[0007] a) "permanent" dyeing, the function of which is to provide a substantial change to the natural colour, and which uses oxidation dyes which penetrate into the hair fibres and form a dye via an oxidation condensation process;

[0008] b) non-permanent, semi-permanent or direct dyeing, which does not use an oxidation condensation process and which resists four or five shampoo washes; it consists in dyeing the keratin fibres with a dye composition containing direct dyes;

[0009] c) temporary dyeing, which brings about a change to the natural colour of the hair which is retained from one shampoo wash to the next, and which is used to enhance or correct a shade which has been obtained. It can also be compared to a "make-up" process.

[0010] Thus, it is known practice to dye keratin fibres, in particular human keratin fibres such as the hair, with a dye composition containing oxidation dye precursors, in particular oxidation coupler bases such as ortho- or para-phenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds such as pyrazoles, pyrazolones or pyrazolopyridines, in order to obtain "permanent" dyeing. These oxidation coupler bases are colourless or weakly coloured compounds which, when combined with oxidizing products, can produce coloured compounds via an oxidation condensation process.

[0011] It is also possible to modify the shade obtained with these oxidation coupler bases by combining them with colour-developing or colour-modifying agents. The various molecules used as oxidation coupler bases and colour-developing agents allow a wide range of colours to be obtained.

[0012] However, the use of these dye compositions can entail a significant number of drawbacks.

[0013] In particular, the dyeing power obtained after application to keratin fibres can not be entirely satisfactory, or even can be weak, and lead to a limited range of colours.

[0014] The colourings can also be insufficiently fast with respect to external agents such as light, shampoo washes or perspiration, and can also be too selective, i.e. too different along the same keratin fibre differently sensitized between its ends and its roots.

[0015] There is therefore a real need to provide a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, which is capable of producing good colour build-up, intensity and chroma, while having low selectivity and good fastness, in particular good resistance to shampoo washes, and which is capable of delivering good dyeing performance even after a period of storage, while having good application qualities and preserving good sensory properties, in particular in terms of shine, smoothness, suppleness, straightening effect and disentangling of the keratin fibres such as the hair.

[0016] These and other objects are achieved by the present application, which is thus one subject of the present application is a composition comprising:

[0017] - at least one compound chosen from hyaluronic acid and / or its derivatives, and mixtures thereof;

[0018] - at least one (hydro)carbonate salt;

[0019] - at least one fatty acid;

[0020] - at least one dye

[0021] wherein the total content of the compound chosen from fatty acids ranges from 0.1% to 10% by weight relative to the total weight of the composition, and wherein the dye is chosen from oxidation dyes, direct dyes and mixtures thereof.

[0022] According to a preferred embodiment, the composition according to the application is a composition for dyeing keratin fibres, in particular the hair.

[0023] The composition according to the application can in particular produce a bright, intense, strong and slightly selective colouring, i.e. a colouring that is uniform along the length of the fibres.

[0024] The composition according to the application has improved resistance to shampoo washes and also good stability over time, in particular with little or no change in its viscosity during storage.

[0025] The compositions according to the invention have good application quality, especially in terms of texture, ease of application, adhesion to hair, and lengthening.

[0026] The compositions according to the invention can also provide good cosmetic quality, especially in terms of luster, smoothness and suppleness, and a more natural feel, while maintaining the integrity of the fibers.

[0027] The compositions according to the present invention can also provide cosmetic compositions for keratin fibers that do not have a strong ammonia odor.

[0028] The subject of this invention is also a method for dyeing hair using the composition of this invention.

[0029] The subject of this invention is also a kit containing a composition as previously defined in a first compartment and an oxidizing composition comprising at least one chemical oxidizing agent in a second compartment.

[0030] According to the present invention, the term "chemical oxidant" means an oxidant other than oxygen in the atmosphere.

[0322] In the following examples, all quantities are given as a mass percentage of the active material (AM) relative to the total weight of the composition (unless otherwise mentioned).

[0323] Composition

[0324] Example 1

[0325] Dye compositions A, B, and C were prepared from the components whose content is indicated in the table below (reactive material %):

[0326] Dye Composition

[0327] [Table 1]

[0328]

[0329] INCI Name: Stearic Acid

[0330] When using, each of the dye compositions A, B, and C is mixed with 1.5 times its weight of oxidant O. Then each of these mixtures is applied at a ratio of 5 g mixture / g hair to strands of permanent wavy grey hair (PWG) and natural grey hair (NG) containing 90% white hair.

[0331] After leaving the hair at 27°C for 35 minutes, rinse, wash with standard shampoo, and dry.

[0332] Results

[0333] Colorimetric measurements were performed in the CIELab system using a Konica Minolta 3600 spectrochromista (light source D65, angle 10°, including specular reflection component).

[0334] Selective

[0335] Color selectivity is the color variation between natural hair (NG) and permanently wavy hair (PWG). Natural hair represents the nature of the hair at the roots, while permanently wavy hair represents the nature of the hair at the ends. Selectivity allows for the assessment of color uniformity along the entire length of the hair fiber.

[0336] Selectivity is measured by the following:

[0337] ΔE (which is the color change between natural hair and permanently wavy hair) is obtained by the following formula:

[0338]

[0339] in Indicates intensity, and and This indicates the color level of naturally dyed hair, and Indicates intensity, and and This indicates the color intensity of permanently wavy hair that has been dyed. The lower the value of E, the lower the selectivity and the more uniform the coloring along the hair strands.

[0340] [Table 2]

[0341]

[0342] Hair strands treated with mixture A+O according to the invention have a much lower ΔE value than hair strands treated with comparative mixtures B+O and C+O. In other words, mixture A+O according to the invention provides hair strands with improved selectivity relative to hair strands treated with comparative mixtures B+O and C+O, and therefore with improved color uniformity from root to tip.

[0343] Fastness

[0344] The persistence of the color was assessed in the same way. This was the color difference ΔE between the dyed strands (according to the formula above) before shampoo washing and then after five shampoo washes. The lower the ΔE value, the more persistent the color is relative to shampoo washing.

[0345] [Table 3]

[0346]

[0347] Hair strands treated with mixture A+O according to the invention have a much lower ΔE value than hair strands treated with comparative mixtures B+O and C+O.

[0348] In other words, the mixture A+O according to the invention provides a uniform color coating on hair, which exhibits improved shampoo resistance compared to hair treated with contrast mixtures B+O and C+O.

[0349] Furthermore, the mixture A+O according to the present invention provides excellent sensory properties.

[0350] Example 2

[0351] Compositions A, B, and O were prepared from the components whose content is indicated in the table below (active material %):

[0352] Dye Composition

[0353] [Table 1]

[0354]

[0355] INCI Name: Stearic Acid

[0356] Oxidation Composition

[0357]

[0358] When using, each of the dye compositions A and B is mixed with 1.5 times its weight of the oxidizing composition O.

[0359] Then each of these mixtures was applied at a ratio of 5 g mixture / g hair to strands of natural gray hair (NG) containing 90% white hair and moderately sensitized hair (AS20).

[0360] After leaving the hair at 27°C for 35 minutes, rinse, wash with standard shampoo, and dry.

[0361] The mixture A+O according to the invention provides improved selectivity for hair strands compared to those treated with the contrasting mixture B+O, and thus improved color uniformity from the root to the tip of the hair.
