Description

[0001] COMPOSITION COMPRISING AN OXIDATION DYE, SPECIFIC CATIONIC AGENTS AND A FATTY ESTER

[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 the hair.

[0003] The invention relates to a composition comprising at least one oxidation dye, specific cationic agents and a fatty ester.

[0004] The invention also relates to a process for treating keratin fibres, in particular the hair, comprising applying the composition according to the invention to said fibres, and also to a kit comprising the composition according to the invention and to 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, 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 colour modifiers, the latter being chosen notably 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.

[0009] The colouring must also be resistant over time and must not become degraded in the presence of external agents such as washing, light, bad weather, rubbing and perspiration.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] The hair may moreover be weakened or damaged by repeated dyeing operations, such that users often also resort to separate hair care products, 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.

[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 sometimes makes it difficult to distribute uniformly over the keratin fibres (running), in particular the hair.

[0012] 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 dyeing keratin fibres, making it possible to obtain colouring of the keratin fibres that is sparingly selective (i.e. uniform from root to end), intense, persistent, chromatic, with good colour build-up, and which are capable of leading to colouring that withstands 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 qualities, 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 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 / conditioning properties on the keratin fibres, more particularly softness to the touch, suppleness, sheen and / or smoothness to the touch.

[0014] Moreover, the formulation of environmentally-friendly cosmetic products, that is to say products, the design and the development of which take environmental issues into account, is becoming a major concern in contributing to answering global challenges.

[0015] It is thus proving essential to provide more sustainable compositions, thereby making it possible to respond to these environmental issues.

[0016] 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 originand more particularly of plant origin, while reducing the use of compounds of petrochemical origin.

[0017] These aims are achieved with the present invention, a subject of which is notably a composition, preferably a cosmetic composition, comprising:

[0018] (i) at least one oxidation dye,

[0019] (ii) at least one cationic surfactant of fatty amine type,

[0020] (iii) at least one cationic polysaccharide, and

[0021] (iv) at least one ester of a C1-C40 carboxylic acid and of a C1-C40 alcohol.

[0022] 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 colour build-up, intensity, chromaticity and fastness.

[0023] 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.

[0024] The compositions according to the invention have good use qualities and good cosmetic properties, notably 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.

[0025] The compositions according to the invention successfully exhibit a firm texture which spreads smoothly on application, while at the same time enabling uniform deposition thereof on the keratin fibres (no dripping), in particular keratin fibres such as the hair.

[0026] It has been found that the compositions according to the invention result in good scalp comfort during application.

[0027] It has also been found that the hair thus treated is particularly shiny, light, soft to the touch, smooth to the touch, supple, easy to disentangle and more manageable.

[0028] In addition, the compositions according to the invention are particularly environmentally friendly, notably in that they comprise few or no compounds of petrochemical origin.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.

[0480] [Table 1]

[0481]

[0482] The dynamic viscosities of the composition Al according to the invention and of the comparative composition A2 were evaluated.A first measurement of the dynamic viscosity of each of the compositions Al and A2 was carried out using a Lamy RM 100 Rheometer, with spindle number 4, at 25°C and atmospheric pressure, at a rotation speed of 200 rpm, the measurement being carried out after 30 seconds of rotation.

[0483] A second measurement of the dynamic viscosity was carried out according to the same protocol, after having mixed each of the compositions Al and A2 with an oxidizing composition O at 20 volumes (i.e. 6% by weight of H2O2) according to an A:O ratio of 1:1.5.

[0484] The visual appearance and the ease of mixing and application of the composition to the hair were also evaluated by an expert for each of the compositions Al and A2 (before and after mixing with the oxidizing composition).

[0490] In addition, the compositions Al and A2 according to the invention made it possible to obtain deep dark brown hair dyeings, with good coverage and a uniform (i.e. sparingly selective) colouring.Example 2:

[0491] The dye composition A3 according to the invention, as described in Table 3 below, was prepared. The amounts are expressed as weight percentages of active material (AM).

[0492] [Table 3]

[0493]

[0494] Protocol:

[0495] At the time of use, the composition A3 was mixed with an oxidizing composition O at 20 volumes (i.e. 6% by weight of H2O2) according to an A:O ratio of 1:1.5.

[0496] The mixtures M(A3+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.

[0497] After a leave-on time of 30 min on a hotplate at 27°C, each lock of hair is rinsed and dried.Evaluation:

[0498] 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.

[0499] 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.

[0500] 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:

[0501]

[0502] 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).

[0503] The results obtained are collated in Table 4 below:

[0504] [Table 4]

[0505]

[0506] It is observed in particular that the selectivity of the dyeing obtained with the composition A3 according to the invention is low. The dyeing obtained with the composition A3 according to the invention is therefore particularly uniform.

[0507] Example 3:

[0508] The dye composition A4 according to the invention and the comparative dye composition A5, as described in the table below, were prepared. The amounts are expressed as weight percentages of active material (AM).[Table 5]

[0509]

[0510] Protocol:

[0511] At the time of use, each of composition A4 and A5 is mixed with an oxidizing composition O at 20 volumes (i.e. 6% by weight of H2O2) according to an A:O ratio of 1:1.5.

[0512] Each of mixtures M(A4+O) and M(AS+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.

[0513] After a leave-on time of 25 min on a hotplate at 30°C, each lock of hair is rinsed and dried.

[0514] Evaluation:

[0515] 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.

[0516] L* represents the intensity of the hair dyeing, measured on the locks of dyed permanent-waved hair.The lower the L* value, the darker, more powerful, more intense the hair dyeing.

[0517] The results obtained are collated in Table 6 below:

[0518] [Table 6]

[0519]

[0520] The hair dyeing obtained with the mixture MA4 +O according to the invention exhibits lower L* values than the hair dyeing obtained with the comparative mixture MA5 +o.

[0521] The mixture MA4 +O according to the invention provides a more intense hair dyeing than with the comparative mixture MAS +O.
