Description

[0001] WASHING AND FOAMING COMPOSITION FOR KERATIN FIBRES, COMPRISING AT LEAST ONE GLUCAMIDE AND A PARTICULAR MIXTURE OF SURFACTANTS

[0002] The present invention relates to a cosmetic, especially hair, in particular foaming, composition for washing keratin materials, comprising multiple anionic surfactants, at least one glucamide compound, at least one amphoteric or zwitterionic surfactant and at least one cationic surfactant chosen from fatty amines.

[0003] The invention also relates to the process for cosmetically treating keratin materials, especially keratin fibres, comprising the application of the composition according to the invention to said keratin materials.

[0004] It is common practice to use detergent compositions (such as shampoos) based essentially on surfactants, for cleansing and / or washing keratin fibres such as the hair. These compositions are applied to wet hair and the foam generated by massaging or rubbing with the hands makes it possible, after rinsing with water, to remove the various types of dirt initially present on the hair or the skin.

[0005] In addition, it is known practice to propose shampoos, in particular for hair that is sensitized or embrittled to various degrees following the action of atmospheric agents or of repeated mechanical or chemical treatments, containing conditioning agents such as silicones, in order to confer upon the keratin fibres conditioning properties, for example a better feel, greater suppleness or easy disentangling.

[0006] However, these washing compositions based on anionic surfactants, generally of sulfate type, and on silicones, have several drawbacks. Notably, the initiation of foaming, the amount of foam generated and more particularly the quality and texture of the foam, are deemed to be insufficient.

[0007] In addition, repeated applications of these silicone-based compositions often have the effect of giving the hair an unpleasant feel (hair gets greasy again very quickly), loss of volume (lank hair) and bounce of the head of hair, and occasionally lack of sheen.

[0008] 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.

[0009] 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 novel cosmetic compositions with a better carbon footprint, especially 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.

[0010] These observations gave rise to the interest in developing a composition which is intended for the treatment of keratin fibres, is advantageously free of anionic surfactants of sulfate type (sulfate-free), has good cosmetic properties and improved working qualities, and which is capable of washing keratin fibres without making them lank, so as to give the keratin fibres good conditioning properties.

[0011] There is therefore a real need to develop compositions which are more environmentally friendly, and preferably free of anionic surfactants of sulfate type, which make it possible to obtain excellent washing and working properties, in particular in terms of the initiation of foaming, quality and amount of foam generated, and more particularly the texture of the foam, in particular having good creaminess.

[0012] It is also advantageous for these compositions to confer good conditioning properties on the keratin fibres, especially in terms of suppleness, smoothness, disentangling and coating of the keratin fibres.

[0013] These aims are achieved with the present invention, a subject of which is notably a composition, preferably a cosmetic composition, comprising:

[0014] (i) at least one first anionic surfactant chosen from acylisethionates,

[0015] (ii) at least one second anionic surfactant chosen from amino acid derivatives,

[0016] (iii) from 0.1% to 10% by weight, relative to the total weight of the composition, of at least one glucamide compound,

[0017] (iv) at least one amphoteric or zwitterionic surfactant, and

[0018] (v) at least one cationic surfactant chosen from fatty amines.

[0019] It has been found that the composition according to the invention has excellent keratin fibre-washing power. In particular, the hair treated with the composition according to the invention is particularly clean and has good cosmetic properties. It makes it possible to remove dirt effectively and obtain a clean visual effect of the keratin fibres.

[0020] It has also been noted that the hair thus treated is particularly light, soft to the touch, smooth to the touch, supple, easy to disentangle and more manageable. The composition according to the invention coats the hair without however making it lank. In addition, it has been observed that the composition according to the invention has good working qualities, notably good initiation of foaming and good foam quality and amount. It has very particularly been noted that the composition according to the invention makes it possible to generate a large amount of foam. The foam generated by the composition according to the invention is rich, creamy, firm and abundant, which is particularly desirable for users.

[0021] A subject of the invention is also a process for treating, especially cosmetically treating, keratin materials, especially 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.

[0475] Handling: the expert holds the lock in one hand; they place the thumb of the other hand on the front of the lock and the index and middle fingers on the back. They slide these three fingers over the lock from root to tip, 3 times.

[0476] Evaluation o f coating:

[0477] Definition: Sensation of product remaining on the lock of hair (presence of a residual film). Handling: the expert holds the lock in one hand; they place the thumb of the other hand on the front of the lock and the index and middle fingers on the back. They slide these three fingers over the lock from root to tip, 3 times. The results are collated in the table below.
