Description

Title of the invention: WASHING COMPOSITION FOR KERATIN FIBERS COMPRISING AT LEAST ONE ANIONIC SURFACTANT, AT LEAST ONE AMPHOTERIC OR ZWITTERIONIC SURFACTANT AND AT LEAST ONE GLUCAMIDE COMPOUND

[0001] The present invention relates to a composition comprising at least one anionic surfactant, at least one amphoteric or zwitterionic surfactant and at least one glucamide compound, with a particular weight ratio of the total content of anionic surfactant(s) (i), to the total content of amphoteric or zwitterionic surfactant(s) (ii).

[0002] The invention relates to a method for treating keratin fibers, comprising at least one step of applying to said keratin fibers a composition according to the invention.

[0003] For cleaning and / or washing keratin fibers such as hair, the use of detergent compositions (such as shampoos) based essentially on surfactants is common. These compositions are applied to wet hair and the foam generated by massage or friction with the hands allows, after rinsing with water, the elimination of various dirt initially present on the hair or skin.

[0004] Also, it is known to propose shampoos, in particular for hair sensitized or weakened to varying degrees following the action of atmospheric agents or repeated mechanical or chemical treatments, containing conditioning agents such as silicones, to give the keratin fibers conditioning properties, for example a better feel, more flexibility or even ease of detangling.

[0005] However, these washing compositions based on surfactants and silicones have several drawbacks: the environmental profile of the composition (biodegradability, water footprint) is not always optimal, due to the presence of silicone; the start of foam, the quality and more particularly the quantity of foam generated are considered insufficient; the rapid regreasing of keratin fibers accompanied by weighting.

[0006] Furthermore, repeated applications of these compositions often have the effect of inducing an unpleasant feel to the hair, a loss of volume and nervousness of the hair, and sometimes a lack of shine.

[0007] From these observations arose the interest in developing a natural cosmetic composition and biodegradable intended for the treatment of keratin fibers, advantageously silicone-free, having improved usage qualities and good cosmetic properties, and capable of washing keratin fibers without weighing them down so as to provide good conditioning properties to the keratin fibers.

[0008] At the same time, more and more users of cosmetic products are looking for more aesthetic, even more original, hair hygiene products.

[0009] There is therefore a real need to develop aesthetic compositions, stable over time, based on natural and / or biodegradable ingredients, preferably not comprising silicone, and making it possible to obtain excellent washing and usage properties, in particular in terms of foam initiation, quality and quantity of foam generated, and viscosity. It is also of interest that these compositions confer good conditioning properties to the keratin fibers, in particular in terms of feel, smoothness, flexibility and detangling.

[0010] These aims are achieved with the present invention which in particular relates to a composition, preferably cosmetic, comprising: i. at least one anionic surfactant, ii. at least one amphoteric or zwitterionic surfactant, and iii. at least one glucamide compound, and

[0011] in which the weight ratio of the total content of anionic surfactant(s) (i) to the total content of amphoteric or zwitterionic surfactant(s) (ii) is less than or equal to 4.5.

[0012] It has been found that the composition according to the invention has excellent washing power for keratin fibers.

[0013] In particular, the hair treated with the composition according to the invention is particularly clean, and has good cosmetic properties.

[0014] It has also been found that hair thus treated is particularly light, soft to the touch, smooth to the touch, supple, easy to detangle and more manageable.

[0015] Furthermore, it has been observed that the composition according to the invention has good qualities of use, in particular good foam start, good quality and quantity of foam. It has been particularly noted that the composition according to the invention makes it possible to generate a large quantity of foam.

[0016] The composition according to the invention has a viscosity suitable for use as a shampoo.

[0017] Furthermore, it has also been found that the composition according to the invention is particularly stable over time, at atmospheric pressure and at 25°C.

[0018] More particularly, when the composition according to the invention further comprises at least one opacifying agent, the composition remains homogeneous and no phenomenon of no phase shift in composition was observed.

[0019] According to an advantageous embodiment of the invention, the composition according to the invention further comprises one or more particles (e.g. opacifiers, pigments, glitter, etc.), in the form of a homogeneous and stable suspension.

[0020] The visually stable and homogeneous suspension of these particles significantly improves the aesthetics and originality of the composition according to the invention.

[0021] By "stable and homogeneous suspension", within the meaning of the invention, it is understood that said particles are dispersed homogeneously in the composition, that is to say distributed homogeneously within the composition, and that this homogeneous dispersion persists over time, that is to say that the particles do not float, do not sink, do not settle and / or do not form agglomerates in the composition over time, in particular after at least one week of storage.

[0022] The invention also relates to a method of treatment, in particular cosmetic treatment, of keratin fibers, in particular human keratin fibers such as hair, comprising at least one step of application to said keratin fibers of a composition according to the invention.

[0023] Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the example which follows.

For this, each expert compares one of the treated strands (by Al or by A2) with a strand of hair treated with a commercial shampoo comprising a silicone and a cationic polymer and according to the same ratio of 0.4 grams of composition / gram of hair.
