Description

[0001] COMPOSITION COMPRISING AN OXIDATION DYE AND / OR AN ALKALINE AGENT, A LIQUID FATTY SUBSTANCE AND A CATIONIC GUAR GUM

[0002] The present invention relates to the field of hair dyeing. The invention is directed towards providing a composition that is capable of serving as a basis for the formulation of all types of compositions that can be used in a process for artificially colouring keratin fibres, preferably the hair.

[0003] The invention relates to a composition comprising at least one oxidation dye, at least one liquid fatty substance and at least one cationic guar gum.

[0004] The invention also relates to a process for treating keratin fibres, in particular the hair, comprising the application to said fibres of the composition according to the invention, and also to a kit comprising the composition according to the invention and an oxidizing composition.

[0005] It is known practice to dye keratin fibres, and in particular human hair, with dye compositions containing oxidation dye precursors, such as oxidation bases, notably ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, are able to produce coloured compounds by a process of oxidative condensation.

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

[0007] The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained.

[0008] “Permanent” dyeing is characterized by the use of oxidation dye precursor(s) (bases and / or couplers) in the presence of oxidizing compound(s). In order to be considered as efficient dyeing, the latter needs to satisfy certain criteria. It must make it possible to obtain shades in the desired intensity with colour differences, between the end and the root of the same lock (also known as the selectivity), which are as small as possible.The colouring must also be resistant over time and must not become degraded in the presence of external agents such as washing, light, climatic conditions, rubbing and perspiration.

[0009] However, the dyeing results obtained are not always very satisfactory, notably in terms of selectivity, colour build-up, chromaticity, intensity and / or persistence, in particular with respect to successive shampoo washes, or of resistance to light or to perspiration.

[0010] Also, the hair can be weakened or damaged by repeated colouring, so users also often resort to separate hair treatments, in order to condition the hair. Treating the hair in two separate steps (colouring, then conditioning) is more complicated to set up, time-consuming and expensive for the user.

[0011] 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 is sometimes difficult to distribute uniformly over the keratin fibres (running), in particular the hair.

[0012] These findings are behind the interest in developing novel compositions, which can serve as a basis for the formulation of all types of compositions that can be used in a keratin fibre dyeing process, making it possible to obtain a colouring on keratin fibres that is sparingly selective (i.e. homogeneous from the root to the end), intense, long-lasting, chromatic, with good colour build-up, and that is capable of affording colourings that are resistant to the various stresses to which the fibres may be subjected, such as weather conditions, washing and perspiration, and that are also capable of affording good dyeing performance even after a period of storage.

[0013] It is also of interest that these new compositions be gentle on the scalp, that they have good working properties such as being easy to mix, having a pleasant odour, a pleasant texture, that they be easy to apply, and that they also impart care / conditioning properties to keratin fibres, more particularly a soft feel, suppleness, sheen and / or a smooth feel.

[0014] Moreover, the formulation of environmentally-friendly cosmetic products, i.e. products whose design and development take account of environmental issues, is becoming a major preoccupation for contributing towards meeting the global challenges.

[0015] It thus proves essential to propose more sustainable compositions, thereby enabling these environmental challenges to be met.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.

[0016] These aims are achieved with the present invention, one subject of which is notably a composition, preferably a cosmetic composition, comprising:

[0017] (i) at least one oxidation dye,

[0018] (ii) at least one fatty substance that is liquid at 25°C and at atmospheric pressure, and (iii) at least one cationic guar gum,

[0019] and for which the weight ratio of the total content of liquid fatty substance(s) (ii) to the total content of cationic guar gum(s) (iii) is in the range from 3 to 10.

[0020] It has been found that the composition according to the invention makes it possible to obtain better dyeing properties. In particular, the colouring obtained is sparingly selective, with good colour build-up, intensity, chromaticity and fastness.

[0021] The keratin fibre colourings obtained with the composition according to the invention are particularly persistent with respect to external agents (washing, light, bad weather, friction, perspiration), and notably persistent with respect to shampoo washing several times.

[0022] The compositions according to the invention have good working qualities and good cosmetic properties, notably a pleasant odour and a texture which differs from hair dye compositions usually used with a creamy and particularly fondant texture on application, notably on contact with keratin fibres such as the hair. The texture of the compositions according to the invention is particularly appreciated in that it is sparingly tacky and fluid, which allows its use for several types of application such as in a bowl or a heating bottle.

[0023] The compositions according to the invention succeed in having a firm and fondant texture on application, while at the same time affording homogeneous deposition thereof on keratin fibres (no running), in particular on keratin fibres such as the hair.

[0024] It has been found that the compositions according to the invention afford good scalp comfort during application.

[0025] It has also been found that the hair thus treated is particularly shiny, light, soft-feeling, smooth-feeling, supple, easy to disentangle and more manageable.In addition, the compositions according to the invention are particularly environmentally friendly, notably in that they comprise few or no compounds of petrochemical origin.

[0026] The invention also relates to a process for treating 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.

[0027] A subject of the invention is also 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.

[0408] [Table 1]

[0409]

[0410] Protocol:

[0412] 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 of hair.

[0413] After leaving on for 30 minutes at a temperature of 27°C, the hair is rinsed and dried in an oven (60°C).

[0414] The colorimetric measurements were performed using a Konica Minolta CM 3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0415] In this system, L* represents the lightness: the lower the value of L*, the darker, more powerful and more intense the hair dyeing.

[0416] Results

[0417] The results are collated in the following table:

[0419]

[0420] The mixture resulting from the dye composition Al and the oxidizing composition provides a more powerful dyeing (lower L* value) compared with the comparative mixture.

[0426] Each of mixtures M(AI+O), M(B2+O), M(B3+O) and M(B4+O) is then applied to a lock of permanent-waved hair containing 90% white hair strands (PWNW) in a proportion of 5 g of mixture per 1 g of hair.After a leave-on time of 35 min on a hotplate at 27°C, each lock of hair is rinsed and dried.

[0427] Evaluation:

[0428] 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.

[0429] L* represents the intensity of the hair dyeing, measured on the locks of dyed permanent-waved hair.

[0430] The lower the L* value, the darker, more powerful, more intense the hair dyeing.

[0431] The results obtained are collated in Table 4 below:

[0432] [Table 4]

[0433]

[0434] The hair dyeing obtained with the mixture MAI +O according to the invention exhibits lower L* values than the hair dyeing obtained with the comparative mixtures M(B2+O), M(B3+O) and M(B4+O).

[0435] The mixture MAI +O according to the invention provides a more intense hair dyeing than with the comparative mixtures M(B2+O), M(B3+O) or M(B4+O).
