Description

[0001] COMPOSITION COMPRISING AN OXIDATION DYE AND / OR AN ALKALINE AGENT, A SPECIFIC CATIONIC GUAR AND A CATIONIC SURFACTANT

[0002] The present invention relates to the field of hair dyeing and hair lightening. It aims to propose a composition capable of serving as a base for the formulation of all types of compositions that can be used in a process for dyeing and / or for artificially lightening keratin fibres, preferably the hair.

[0003] The invention relates to a composition comprising at least one oxidation dye and / or alkaline agent, at least one specific cationic guar and at least one specific cationic surfactant.

[0004] The invention also relates to a process for treating keratin fibres, in particular the hair, comprising the application of the composition according to the invention to said fibres, and also 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 dyeing compositions containing oxidation dye precursors, such as oxidation bases, especially 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, can give rise to coloured compounds by a process of oxidative condensation.

[0006] It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or colouring modifiers, the latter being chosen in particular from aromatic meta-diaminobenzenes, meta-aminophenols, metadiphenols 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 a 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, especially in terms of selectivity, of colour build-up, of chromaticity, of intensity and / or of 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 colourings, such that users often resort in addition to distinct hair care products, in order to provide conditioning to the hair. This hair treatment in two distinct steps (dyeing, then conditioning) is more complicated to set up, time consuming and expensive for the user.

[0011] In addition, current hair dyeing 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] Thus, there is still a need to provide new compositions, which can serve as a basis for the formulation of all types of compositions that can be used in a process for dyeing keratin fibres, making it possible to obtain a colouring of keratin fibres that is not very selective (i.e. is uniform from root to end), and is intense, persistent and chromatic, with good colour build-up, and which are capable of leading to colourings resistant to the various attacks that the fibres may undergo, such as climatic conditions, washing and perspiration, and also capable of leading to good dyeing performance even after a period of storage.

[0013] It is also advantageous that these new compositions are not very aggressive for the scalp, that they have good properties of use, such as a pleasant odour, a pleasant texture, that they are easy to apply, and that they also confer care / conditioning properties on keratin fibres, more particularly softness to the touch, suppleness, sheen and / or a smoothness to the touch.

[0014] Moreover, the formulation of environmentally friendly cosmetic products, i.e. products designed and developed while taking account of environmental issues, is becoming a major concern in helping to meet global challenges.

[0015] It is thus proving essential to propose more sustainable compositions, thereby making it possible to respond to these environmental issues.In this context, it is important to develop new 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 vegetable origin, while reducing the use of compounds of petrochemical origin.

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

[0017] (i) at least one oxidation dye and / or at least one alkaline agent,

[0018] (ii) at least one cationic guar with the INCI name: Hydroxypropyl guar hydroxypropyltrimonium chloride having an average molecular weight ranging from 2 000000 g / mol to 3 500000 g / mol, and

[0019] (iii) at least one cationic surfactant chosen from cationic surfactants of fatty amine type, cationic surfactants of quaternary ester type, and mixtures thereof.

[0020] It has been noted that the composition according to the invention makes it possible to obtain better dyeing properties. In particular, the colouring obtained is not very selective, with good colour build-up, intensity, chromaticity and persistence.

[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, rubbing, perspiration), and especially persistent with respect to several shampoo washes.

[0022] The compositions according to the invention have good qualities of use and good cosmetic properties, in particular an agreeable odour and a texture which distinguish them from the hair dyeing compositions normally used with a cream texture which is compact and particularly soft on application, in particular in contact with keratin fibres such as the hair. This particular cream texture makes it possible notably to facilitate application of the composition according to the invention to the roots of keratin fibres, in particular the hair, leading to better coverage of the roots of keratin fibres, in particular the hair, by the composition according to the invention.

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

[0024] It has been found that the compositions according to the invention result in good scalp comfort during application.It has also been noted that the hair thus treated is particularly shiny and light, has a soft and smooth feel, and is supple, easy to disentangle, more manageable, and sheathed.

[0025] In addition, the compositions according to the invention are particularly environmentally friendly, notably by comprising no or few compounds of petrochemical origin.

[0026] A subject of the invention is also 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 multicompartment device comprising at least a first compartment containing the composition according to the invention, and at least a second compartment containing an oxidizing composition.

[0415] Examples

[0416] Example 1:

[0417] The dyeing composition Al according to the invention, as described in the table below, was prepared. The amounts are expressed as weight percentages of active material (AM).

[0418] [Table 1]

[0419]

[0420] At the time of use, the dyeing composition Al is mixed with 1.5 times its weight of an oxidizing composition O at 20 volumes (i.e. 6% by weight of H2O2), inorder to obtain a dyeing composition M according to the invention (i.e. derived from the mixture A 1+0).

[0421] The composition M resulting from the mixing is applied to locks of hair containing 90% natural grey hair, in a proportion of 5 g of mixture per 1 g of hair. After 30 minutes of leave-on time at a temperature of 27°C, the hair is rinsed and dried in an incubator (60°C).

[0422] The dyeing of the hair treated with composition M according to the invention presents a good intensity, chromaticity and fastness, with also with a good color buildup and low selectivity.

[0423] The composition M according to the invention leads to good comfort of the scalp during application, and has a pleasant odour, and also a covering texture with good adhesion of the composition to the treated hair, in particular to the roots of the hair, allowing a uniform deposit of said composition on the keratin fibres (no running).

[0424] The hair treated with composition M according to the invention is particularly shiny, light, soft to the touch, smooth to the touch, supple, easy to disentangle, more manageable and coated.

[0425] Example 2:

[0426] The dye composition A2 according to the invention and the comparative dye compositions Bl and B2 as described in Table 2 below, was prepared. The amounts are expressed as weight percentages of active material (AM).[Table 2]

[0427]

[0428] Protocol:

[0429] At the time of use, each of the compositions A2, Bl and B2 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.

[0430] Each of the mixtures M(A2+O), M(BI+O) and M(B2+O) is then applied to a lock of natural hair containing 90% white hair strands (NW) and 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 30 min on a hotplate at 27°C, each lock of hair is rinsed and dried.Evaluation:

[0431] 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.

[0432] In this system, L* represents the intensity: the lower the value of L*, the deeper, more powerful and more intense the dyeing obtained. The chromaticity is measured by the values a* and b*, a* representing the green / red colour axis and b* the blue / yellow colour axis.

[0433] The selectivity is represented by the colour difference AE between the locks of dyed natural non-permanent-waved (NW) hair and the dyed permanent-waved locks (PWNW), and is obtained by the following formula:

[0434]

[0435] In this equation, L*, a* and b* represent the values measured on the locks of dyed non-permanent-waved natural (NW) hair, and Lo*, ao* and bo* represent the values measured on the locks of dyed permanent-waved (PWNW) hair. The lower the value of AE, the lower and therefore better the selectivity (uniform dyeing).

[0436] The results obtained are collated in Table 3 below:

[0437] [Table 3]

[0438]

[0439] It is observed that the selectivity of the dyeing obtained with the composition A2 according to the invention is lower than the dyeing obtained with the comparative compositions Bl and B2. The dyeing obtained with the composition A2 according to the invention shows therefore better uniformity compared to the dyeing obtained with compositions B 1 or B2.
