Description

Title of the invention: COMPOSITION COMPRISING AT LEAST ONE OXIDATION COUPLER, AT LEAST ONE FAT, AT LEAST ONE CATIONIC GUAR GUM AND AT LEAST ONE CATIONIC SURFACTANT

[0001] The invention relates to a composition comprising at least one particular oxidation coupler, at least one fat, at least one cationic guar gum and at least one cationic surfactant.

[0002] The present invention also relates to a method for coloring keratin fibers, preferably human keratin fibers, such as hair, implementing the composition according to the invention as described above.

[0003] Similarly, the invention also relates to a coloring device, or coloring kit, comprising the composition according to the invention and at least one oxidizing composition.

[0004] For a long time, many people have sought to change the color of their hair, and in particular to cover their white hair.

[0005] It is known to dye keratin fibers, and in particular human hair, with dye compositions containing precursors of oxidation dyes, such as oxidation bases, notably ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing agents, can give rise to colored compounds through an oxidative condensation process.

[0006] It is also known that the shades obtained with these oxidation bases can be varied by combining them with color couplers or modifiers, the latter being chosen in particular from among aromatic meta-diaminobenzenes, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indolic compounds.

[0007] The variety of molecules involved at the level of the oxidation bases and the couplers allows for the obtaining of a rich palette of colors.

[0008] Permanent hair coloring is characterized by the use of oxidation color precursor(s) (bases and / or couplers) in the presence of oxidizing compound(s). To be considered effective, it must meet certain criteria. It must allow for the creation of shades in the desired intensity with the smallest possible color variations between the tip and root of the same strand (also called selectivity).

[0009] The colouring must also be resistant over time and not degrade in the presence of external agents such as washing, light, weathering, friction and perspiration.

[0010] However, the coloring results obtained are not always very satisfactory, particularly in terms of selectivity, color rise, chromaticity, intensity and / or persistence, especially with successive shampoos, or resistance to light or perspiration.

[0011] Also, hair can be weakened or damaged by repeated coloring, so users often also resort to separate hair care products to condition the hair. This two-step hair treatment (coloring, then conditioning) is more complicated to implement, time-consuming, and expensive for the user.

[0012] In addition, current compositions for hair colorings generally have the following disadvantages: conditioning properties that are not entirely satisfactory, an odor that can be unpleasant, scalp discomfort and / or a texture that is sometimes difficult to distribute evenly on keratin fibers (running), especially hair.

[0013] From these observations arose the interest in developing new compositions that would produce a low-selective (i.e. homogeneous from root to tip) intense, tenacious, chromatic colouring of keratinous fibres, with good colour lift, and that would be capable of producing colours resistant to the various aggressions that fibres may undergo, such as climatic conditions, washing and perspiration, and also capable of producing good dyeing performance even after a period of storage.

[0014] It is also of interest that these new compositions be not very aggressive to the scalp, that they have good properties of use such as a pleasant smell, a pleasant texture, that they are easy to apply, and that they also give care / conditioning properties to the keratin fibers, more particularly softness to the touch, suppleness, shine and / or a smooth feel.

[0015] Furthermore, 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 in order to help meet global challenges.

[0016] It is therefore essential to propose more sustainable compositions that make it possible to respond to these environmental challenges.

[0017] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good naturalness index and / or of natural origin and more particularly of plant origin while reducing the use of petrochemical compounds.

[0018] These objectives are achieved with the present invention, which relates in particular to a composition, preferably cosmetic, comprising: (i) at least one coupler selected from 6-hydroxybenzomorpholine of formula (II), its addition salts, its solvates and / or the solvates of its salts, hydroxyethyl-3-4-methylenedioxyaniline of formula (III), its addition salts, its solvates and / or the solvates of its salts, 2-amino 5-ethylphenol of formula (IV), its addition salts, its solvates and / or the solvates of its salts, and mixtures thereof; (IV) (III) (ii) at least one fat other than fatty acids, (iii) at least one cationic guar gum, and (iv) at least one cationic surfactant.

[0019] The composition according to the invention makes it possible to achieve the above objectives, in particular in terms of color rise, color strength, chromaticity, selectivity, tenacity and qualities of use.

[0020] In particular, the composition according to the invention makes it possible to produce powerful and not very selective colorations.

[0021] The colors of the keratin fibers obtained with the composition according to the invention are particularly resistant to external agents (washing, light, climatic conditions, friction, perspiration), in particular resistant to several shampoos.

[0022] The compositions according to the invention have good qualities of use and good cosmetic properties, in particular an appreciable odor and a differentiating texture compared to the hair coloring compositions usually used with a creamy texture and particularly melting upon application, especially in contact with keratin fibers such as hair.

[0023] The compositions according to the invention succeed in presenting a firm and melting texture upon application, while allowing homogeneous deposition of the latter on keratin fibers (no drips), in particular keratin fibers such as hair.

[0024] The compositions according to the invention lead to good scalp comfort during application.

[0025] It has also been found that hair treated in this way is particularly shiny, light, soft to the touch, smooth to the touch, supple, easy to detangle and more manageable.

[0026] In addition, the compositions according to the invention are particularly environmentally friendly, in particular by not comprising any or very few compounds of petrochemical origin.

[0027] The present invention also relates to a method for coloring keratin fibers, in particular human keratin fibers such as hair, comprising at least one step of applying to said keratin fibers a composition according to the invention.

[0028] Similarly, the present invention also relates to the use of the composition, as described above, for coloring keratin fibers, in particular human keratin fibers such as hair.

[0029] The invention also relates to a multi-compartment device comprising at least a first compartment containing the composition according to the invention and at least a second compartment containing an oxidizing composition.

[0374] The colour composition Al according to the invention and the comparative composition B1 as described in the table below were prepared. The quantities are expressed as % by weight of active material (ma).

[0375] [Tables 1] Al Invention B1 Comparative Brassicamidopropyl dimethylamine 0.5 0.5 Dipalmitoylethyl hydroxyethylmonium methoside 0.9 0.9 Ammonium hydroxide 4.57 4.57 Cetyl esters 4 4 Cetearyl alcohol 16.1 16.1 Hydroxybenzomorpholine 0.35 0.35 2-Methoxymethyl-p-phenylenediamine 0.35 0.35 Tetrasodium glutamate diacetate 0.24 0.24 Guar chloride hydroxypropyltrimonium 0.5 - Hydroxypropyl guar - 0.5 Antioxidants, reducing agents qs qs Helianthus annuus (sunflower) seed oil 2 2 Glyceryl stearate 2 2 Water qsp 100 qsp 100 Protocol

[0376] At the time of use, the colour compositions Al and B1 are mixed with 1.5 times their weight of an oxidizing composition (O) at 20 volumes (i.e. 6% by weight of H2O2).

[0377] Each of the mixtures is applied to strands of hair that are 90% natural white (BN), at a ratio of 5g of mixture to 1g of hair.
