Description

[0001] COMPOSITION COMPRISING AN OXIDATION DYE AND / OR AN ALKALINE AGENT, AND TWO SPECIFIC CATIONIC SURFACTANTS

[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 which can be used in a process for the dyeing and / or the artificial lightening of keratin fibres, preferably the hair.

[0003] The invention relates to a composition comprising at least one oxidation dye and / or alkaline agent and two or more specific cationic surfactants, but not comprising any chemical oxidizing agent.

[0004] The invention also relates to a process for treating keratin fibres, especially the hair, comprising the application of the composition according to the invention to said fibres, and 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 the 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, are able to 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 the molecules deployed as oxidation bases and couplers allows a rich palette 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 needs to satisfy certain criteria. It must make it possible to obtain shades in the desired intensity, with colour differences between the tip and the root of the same lock (also known as 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, such that users often also have to resort to separate haircare operations in order to condition the hair. This hair treatment in two distinct stages (dyeing, 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 sometimes makes it difficult to distribute the composition uniformly over the keratin fibres (dripping), 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 the dyeing of keratin fibres, making it possible to obtain colouring of keratin fibres that is intense, long-lasting, chromatic, with good colour build-up and with low selectivity (i.e. homogeneous from root to tip), and which are capable of leading to colouring that is resistant to the various attacks to which the fibres may be subjected, such as bad weather, washing and perspiration, and also capable of resulting in good dyeing performance even after a period of storage.

[0013] It is also of interest that these new compositions should be gentle on the scalp, that they have good use properties such as a pleasant smell, a pleasing texture, that they should be easy to apply, and that they also confer care / conditioning properties on the keratin fibres, more particularly softness to the touch, suppleness, shine and / or smoothness to the touch.

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

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

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

[0018] (i) at least one oxidation dye and / or at least one alkaline agent,

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

[0020] (iii) at least one quaternary ester cationic surfactant, and

[0021] (iv) at least one cationic galactomannan gum;

[0022] and said composition being free of chemical oxidizing agent.

[0023] 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.

[0024] 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 multiple shampoo washes.

[0025] 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.

[0026] The compositions according to the invention successfully combine a firm texture which spreads easily on application, with at the same time homogeneous deposition thereof on the keratin fibres (no dripping), in particular keratin fibres such as the hair.

[0027] It has been found that the compositions according to the invention do not irritate the scalp during application.

[0028] 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.

[0029] In addition, the compositions according to the invention are particularly environmentally friendly, notably in that they comprise few or no compounds of petrochemical origin.Another subject of the invention is 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.

[0486] Examples

[0487] Example 1:

[0488] Dyeing composition Al according to the invention and comparative dyeing composition A2 as described in the table below were prepared. The amounts are expressed as weight percentages of active material (am).

[0489] [Table 1]

[0490]

[0491] Protocol:

[0492] At the time of use, each of the compositions Al and A2 is mixed with an oxidizing composition O at 20 volumes (i.e. 6% by weight of H2O2) in an A:O ratio of 1:1.5.Each of the mixtures M(AI+O) and M(A2+o) is then applied to a lock of hair containing 90% natural white hair (NW) and a lock of permanent-waved 90% natural white hair (PWNW) in a proportion of 5 g of mixture per 1 g of hair.

[0493] After a wait time of 30 min on a hotplate at 27 °C, each lock of hair is rinsed and dried.

[0494] Evaluation:

[0495] 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.

[0496] 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.

[0497] 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 via the formula below:

[0498]

[0499] 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).

[0500] The results obtained are grouped together in Table 2 below:

[0501] [Table 2]

[0502]

[0503] The dyeing obtained with the mixture MAI+O according to the invention has AE values lower than that of the dyeing obtained with the comparative mixture MA2+O.It is thus observed that the selectivity of the dyeing obtained with the composition according to the invention is better than the selectivity of the dyeing obtained with the comparative composition.

[0504] The dyeing obtained with the composition according to the invention is therefore more homogeneous than the dyeing obtained with the comparative composition.

[0505] Example 2:

[0506] The dye composition A3 according to the invention and the comparative dye composition A4, as described in the table below, were prepared. The amounts are expressed as weight percentages of active material (AM).

[0507] [Table 3]

[0508]

[0509] Protocol:

[0510] At the time of use, each of composition A3 and A4 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.

[0511] Each of mixtures M(A3+o) and M(A4+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.

[0512] After a leave-on time of 25 min on a hotplate at 30°C, each lock of hair is rinsed and dried.

[0513] Evaluation:

[0514] 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.

[0515] L* represents the intensity of the hair dyeing, measured on the locks of dyed permanent- waved hair.

[0516] The lower the L* value, the darker, more powerful, more intense the hair dyeing.

[0517] The results obtained are collated in Table 4 below:

[0518] [Table 4]

[0519]

[0520] The hair dyeing obtained with the mixture MA3 +0 according to the invention exhibits lower L* values than the hair dyeing obtained with the comparative mixture MA4 +O.

[0521] The mixture MA3 +0 according to the invention provides a more intense hair dyeing than with the comparative mixture MA4 +0.
