Description

[0001] COMPOSITION COMPRISING A DYE, A PARTICULAR CATIONIC GUAR AND A CATIONIC SURFACTANT

[0002] The present invention relates to the field of hair dyeing. It aims to provide a composition capable of serving as a basis for the formulation of all types of compositions that can be used in a process for the artificial dyeing of keratin fibres, preferably of the hair.

[0003] The invention relates to a composition comprising at least one dye, at least one particular cationic guar and at least one cationic surfactant.

[0004] The invention also relates to a process for the treatment of keratin fibres, in particular the hair, comprising applying the composition according to the invention to said fibres.

[0005] Many people have sought for a long time to modify the colour of their hair and in particular to mask their grey hair.

[0006] In the field of dyeing hair keratin fibres, in particular human hair keratin fibres, it is already known practice to dye hair keratin fibres via various techniques using direct dyes or pigments for non-permanent dyeing, or dye precursors for permanent dyeing.

[0007] There are essentially three types of process for dyeing the hair:

[0008] a) “permanent” dyeing, the function of which is to afford a substantial modification to the natural colour and which uses oxidation dyes which penetrate into the hair fibre and forms the dye via an oxidative condensation process;

[0009] b) non-permanent, semi-permanent or direct dyeing, which does not use the oxidative condensation process and withstands four or five shampoo washes; it consists in dyeing keratin fibres with dye compositions containing direct dyes;

[0010] c) temporary dyeing, which gives rise to a modification of the natural colour of the head of hair that remains from one shampoo wash to the next, and which serves to enhance or correct a shade that has already been obtained. It may also be likened to a “makeup” process.

[0011] It is thus known practice to dye keratin fibres, in particular human keratin fibres such as the hair, to obtain “permanent” dyeing with dye compositions containing oxidation dye precursors, in particular oxidation bases, such as ortho- or paraphenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolopyridines. These oxidation bases are colourless orweakly coloured compounds which, when combined with oxidizing products, can give rise to coloured compounds via a process of oxidative condensation.

[0012] It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or colouring modifiers. The variety of molecules employed as oxidation bases and couplers allows a wide range of colours to be obtained.

[0013] However, the use of these dye compositions may entail a certain number of drawbacks.

[0014] Specifically, after application to keratin fibres, the dyeing power obtained may not be entirely satisfactory, or may even be weak, and lead to a limited range of colours.

[0015] The colourings may also be insufficiently fast with respect to external agents such as light, shampoo washing or perspiration, and may also be too selective, i.e. the difference in colouring is too great along a given keratin fibre that is differently sensitized between its tip and its root.

[0016] The hair may moreover be weakened or damaged by repeated dyeing operations, such that users often also have to resort to separate hair care operations in order to condition the hair. This treatment of the hair in two separate steps (dyeing, then conditioning) is more complicated to set up, time-consuming and expensive for the user.

[0017] In addition, current hair dye compositions generally have the following drawbacks: conditioning properties that are not entirely satisfactory, an odour that may be unpleasant, discomfort of the scalp and / or a texture that sometimes makes it difficult to distribute homogeneously over the keratin fibres (dripping), in particular the hair.

[0018] These findings are behind the interest in developing new compositions which can serve as a basis for the formulation of all types of compositions that can be used in a process for the dyeing of keratin fibres, making it possible to obtain dyeing of keratin fibres that is sparingly selective (i.e. homogeneous from root to tip), intense, long-lasting, chromatic, with good colour build-up, and which are capable of leading to colouring that is resistant to the various attacks to which the fibres may be subjected, such as climatic conditions, washing and perspiration, and also capable of resulting in good dyeing performance even after a period of storage.

[0019] It is also of interest that these new compositions be gentle on the scalp, that they have good use properties such as being easy to mix, having a pleasant smell, a pleasant texture, that they be easy to apply, and that they also impart care / conditioningproperties on the keratin fibres, more particularly softness to the touch, suppleness, shine and / or smoothness to the touch.

[0020] Moreover, the formulation of environmentally friendly cosmetic products, that is to say products of which the design and development take account of environmental issues, is becoming a major concern for contributing toward meeting global challenges.

[0021] It is thus essential to propose more sustainable compositions, thereby making it possible to respond to these environmental issues.

[0022] In this context, it is important to develop novel cosmetic compositions with a better carbon footprint, notably by promoting the use of starting materials that are renewable and / or that have a good naturalness index and / or that are of natural origin and more particularly of plant origin, while reducing the use of compounds of petrochemical origin.

[0023] These aims are achieved with the present invention, a subject of which is in particular a composition, preferably a cosmetic composition, comprising:

[0024] (i) at least one dye,

[0025] (ii) at least one cationic guar with the INCI name: Guar hydroxypropyltrimonium chloride, and having a dynamic viscosity of between 500 and 1500 mPa.s, measured at a concentration of 1% by weight in water at 25 °C and at atmospheric pressure, and (iii) at least one cationic surfactant chosen from cationic surfactants of fatty amine type, cationic surfactants of quaternary ester type, and mixtures thereof.

[0026] It has been found that the composition according to the invention makes it possible to obtain better dyeing properties. In particular, the colouring obtained has low selectivity with good colouring build-up, intensity, chromaticity and fastness.

[0027] The keratin fibre colourings obtained with the composition according to the invention are particularly persistent with respect to external agents (washes, light, climatic conditions, friction, perspiration), and especially persistent with respect to multiple shampoo washes.

[0028] The compositions according to the invention have good use qualities and good cosmetic properties, in particular an agreeable odour and a texture which differs from the hair dyeing compositions usually used, with a creamy texture and spreading particularly smoothly on application, in particular in contact with keratin fibres such as the hair. The texture of the compositions according to the invention is particularlyappreciated in that it is not very sticky and fluid, enabling its use for various types of application such as using a bowl or a squeezy applicator bottle.

[0029] The compositions according to the invention successfully exhibit a firm texture which spreads smoothly on application, while at the same time enabling homogeneous deposition thereof on the keratin fibres (no dripping), in particular keratin fibres such as the hair.

[0030] It has been found that the compositions according to the invention result in good scalp comfort during application.

[0031] It has also been found that the hair thus treated is particularly glossy, light, soft to the touch, smooth to the touch, supple, easy to disentangle and more manageable.

[0032] In addition, the compositions according to the invention are particularly environmentally friendly, notably in that they comprise few or no compounds of petrochemical origin.

[0033] A subject of the invention is also a process for the treatment of keratin fibres, in particular human keratin fibres such as the hair, comprising at least one step of applying a composition according to the invention to said keratin fibres.

[0408] Examples

[0409] Example 1

[0410] Dyeing composition Al according to the invention and comparative composition Bl, as described in the table below, were prepared. The amounts are expressed as weight percentages of active material (AM).[Table 1]

[0411]

[0412] The guar hydroxypropyltrimonium chloride used to prepare the composition Al according to the invention has a dynamic viscosity of between 500 and 1500 mPa.s, measured at a concentration of 1% by weight in water at 25° C and at atmospheric pressure.

[0413] Protocol:

[0414] At the time of use, each of the compositions Al and Bl are mixed with 1.5 times their weight of an oxidizing composition O containing 5.5% by weight of H2O2.

[0415] Each of the mixtures M(AI+O) and M(BI+O) is applied to locks of natural hair containing 90% white hair strands (NW) in a proportion of 5 g of mixture per 1 g ofhair. After a leave-on time of 30 minutes at a temperature of 27 °C, the hair is rinsed and dried in an oven (60°C).

[0416] Colorimetric measurements were performed using a Konica Minolta CM 3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0417] In this system, L* represents the intensity: the lower the value of L*, the deeper, more powerful and more intense the dyeing.

[0418] The results are collated in the following table:

[0419] [Table 2]:

[0420]

[0421] The mixture obtained from the dye composition Al and the oxidizing composition results in a more powerful dyeing (lower L* value) compared with the dyeing obtained with the comparative mixture MBI+O.

[0422] Example 2:

[0423] The dye composition A2 according to the invention and the comparative dye compositions B2 and B3 as described in Table 3 below, was prepared. The amounts are expressed as weight percentages of active material (AM).[Table 3]

[0424]

[0425] The guar hydroxypropyltrimonium chloride used for the preparation of composition A2 has a dynamic viscosity of between 500 and 1 500 mPa.s, measured at a concentration of 1% by weight in water at 25°C and at atmospheric pressure.

[0426] The guars hydroxypropyltrimonium chloride used for the preparation of compositions B2 and B3, namely Jaguar® Cl 3 S and Jaguar® C17, do not have a dynamic viscosity of between 500 and 1 500 mPa.s, measured at a concentration of l% by weight in water at 25°C and at atmospheric pressure.Protocol:

[0427] At the time of use, each of the compositions A2, B2 and B3 is mixed with an oxidizing composition O at 20 volumes (i.e. 6% by weight of H2O2) according to a (A or B):O ratio of 1:1.5.

[0428] Each of the mixtures M(A2+o), M(B2+O) and M(B3+o) is then applied to a lock of natural hair containing 90% white hair strands (NW) in a proportion of 5 g of mixture per 1 g of hair. After a leave-on time of 30 min on a hotplate at 27°C, each lock of hair is rinsed and dried.

[0429] Evaluation:

[0430] The colorimetric measurements were performed on each of the treated locks using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0431] L* represents the intensity of the hair dyeing, measured on the locks of dyed hair. The lower the L* value, the darker, more powerful, more intense the hair dyeing.

[0432] The results obtained are collated in Table 4 below:

[0433] [Table 4]

[0434]

[0435] The hair dyeing obtained with the mixture MA2 +0 according to the invention exhibits lower L* values than the hair dyeings obtained with the comparative mixtures MB2 +0 or MB3+O.

[0436] The mixture MA2 +0 according to the invention provides a more intense hair dyeing than with the comparative mixtures MB2 +0 or MB3 +0.
