Description

Title of the invention: WASHING COMPOSITION FOR KERATINIC FIBERS COMPRISING AT LEAST ONE GLUCAMIDE, ONE (POLY)GLYCEROL ESTER AND ONE ALKYL(POLY)GLYCOSIDE

[0001] The present invention relates to a composition comprising at least one anionic surfactant, at least one amphoteric or zwitterionic surfactant, at least one glucamide compound, at least one fatty acid and (poly)glycerol monoester and at least one alkyl(poly)glycoside, and with the weight ratio of the total content of alkyl(poly)glycoside(s), to the total content of particular fatty acid and (poly)glycerol monoester(s).

[0002] The invention relates to a process 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 primarily on surfactants is common. These compositions are applied to wet hair, and the lather generated by massaging or rubbing with the hands allows, after rinsing with water, the removal of various types of dirt initially present on the hair or skin.

[0004] Also, it is known to offer shampoos, especially 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 keratin fibers conditioning properties, for example a better feel, more suppleness or even ease of detangling.

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

[0006] In addition, repeated applications of these compositions often result in an unpleasant feel to the hair, a loss of volume and bounce in the hair, and sometimes a lack of shine.

[0007] From these observations arose the interest in developing a natural and biodegradable cosmetic composition intended for the treatment of keratin fibers, advantageously without silicone (“silicone-free” in English), presenting 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, or even more original, hair hygiene products.

[0009] There is therefore a real need to develop aesthetically pleasing compositions that are stable over time, based on natural and / or biodegradable ingredients, preferably without silicone, and that provide excellent cleansing and usage properties, particularly in terms of foam initiation, quality and quantity of foam generated, and viscosity. It is also important that these compositions impart good conditioning properties to keratin fibers, especially in terms of feel, smoothness, suppleness, and detangling.

[0010] These objectives are achieved with the present invention, which relates in particular to a composition, preferably cosmetic, comprising: i. at least one anionic surfactant, ii. at least one amphoteric or zwitterionic surfactant, iii. at least one glucamide compound, iv. at least one monoester of fatty acid and (poly)glycerol, and v. at least one alkyl(poly)glycoside, and

[0011] in which the weight ratio of the total content of alkyl(poly)glycoside(s) to the total content of fatty acid monoester(s) and (poly)glycerol is less than or equal to 1.

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

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

[0014] It has also been found that hair treated in this way 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 exhibits good performance characteristics, in particular good foam initiation, and good foam quality and quantity. It has been noted in particular that the composition according to the invention, and more specifically the presence of at least one glucamide compound, at least one alkylpolyglucoside, and at least one (poly)glycerol ester, 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 observed 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 phase shift phenomenon of the composition has been 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", in the sense 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 treatment process, particularly cosmetic, of keratin fibers, in particular human keratin fibers such as hair, comprising at least one step of applying to said keratin fibers a composition according to the invention.

[0237] 2.1 Smoothing to the touch: The smoothness of the hair treated with compositions Al and A2 of example 1 (invention) or composition B (comparative) was evaluated.

[0238] Compositions A1, A2 and B were respectively applied to strands of moderately sensitized Caucasian hair (SA20) of 1g and measuring 27cm in length, at a ratio of 0.4 gram of composition / gram of hair.

[0239] The smoothness was then evaluated for each of the treated hair strands (dry or wet), by measuring the friction effort (i.e. friction work in mJ) using a Lloyd Instrument tensile-compression machine (Ametek®).

[0240] More specifically, the frictional effort between the wick to be evaluated (dry or wet) and two rollers of the traction-compression machine which pass along the wick, from root to tips at constant speed, and which simulate the consumer's fingers, is measured in mJ.

[0251] Compositions Al and A2 according to the invention were respectively applied to strands of moderately sensitized Caucasian hair (SA20) at a ratio of 0.4 gram of composition / gram of hair.

[0252] A sensory evaluation of the conditioning properties of each treated strand, first dry and then wet, was carried out by 3 experts. For this, each expert compared one of the treated strands (with Al or A2) with a strand of hair treated with a commercial shampoo containing a silicone and a cationic polymer, using the same ratio of 0.4 grams of composition per gram of hair.

[0253] Each expert then rates the hair strands treated according to the invention, according to the following notation: +3: much, much better than with commercial shampoo, +2: much better than with commercial shampoo. +1: better than with commercial shampoo, +0.5: slightly better than with commercial shampoo, 0: similar to the strand treated with commercial shampoo, -0.5: slightly worse than with commercial shampoo, -1: worse than with commercial shampoo.

[0259] 4.1 Smooth feel and detangling: Al or B2 compositions are applied to moderately sensitized strands (alkaline solubility = 20%, SA 20) which have been previously moistened, in a standardized manner by massaging the strands for 15 seconds (6 passes between the fingers) at a rate of lg / 2.7g of hair.

[0260] After 1 minute pause, the hair is rinsed for 20 seconds (25 passes between the fingers).

[0261] The hair is then wrung out, and its smooth feel is evaluated while still wet; the hair is then air-dried and detangling is evaluated on dry hair.

[0262] The impact of the invention on performance in terms of smooth touch was evaluated on wet hair by 5 experts, in a blind test, on a rating scale from 0 (low) to 8 (very good).

[0263] In order to assess the smooth touch, the expert grasps the lock between the thumb and forefinger and slides his fingers along the lock from the top to the tips;

[0264] It assesses whether the hair is soft, whether it has no roughness, whether it does not catch the fingers, whether the touch is homogeneous.

[0265] The results are grouped in the table below.
