Description

Technical Field

[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 and at least one cationic galactomannan gum, having a specific weight ratio of the total content of the anionic surfactant (i) to the total content of the amphoteric or zwitterionic surfactant (ii).

[0002] The present invention relates to a process for treating keratin fibres, comprising at least one step of applying to said keratin fibres a composition according to the invention. Background Art

[0003] It is common practice to use detergent compositions (such as shampoos) that are essentially based on surfactants for cleaning and / or washing keratin fibers such as hair. These compositions are applied to wet hair and the foam generated by massaging or rubbing with the hands makes it possible to remove many types of dirt originally present on the hair or skin after rinsing with water.

[0004] Furthermore, it is known to propose shampoos, in particular for hair sensitized or brittle to varying degrees after the action of atmospheric agents or repeated mechanical or chemical treatments, which contain conditioning agents such as silicones in order to impart conditioning properties to the keratin fibers, such as a better feel, greater manageability or additional ease of detangling.

[0005] However, these cleaning compositions based on surfactants and silicones have several drawbacks: the environmental profile of the compositions (biodegradability, water footprint) is not always optimal due to the presence of silicones; the onset of foaming, the quality and more particularly the amount of foam produced are poorly judged; the keratin fibres re-oil quickly, with attendant thinning.

[0006] Additionally, repeated application of these compositions often has the effect of imparting an unpleasant feel to the hair, loss of volume and vitality throughout the head of hair, and occasionally loss of shine.

[0007] These observations have given rise to an interest in developing natural and biodegradable cosmetic compositions intended for the treatment of keratin fibres, which are advantageously silicone-free, have improved processing qualities and good cosmetic properties, and which are capable of washing the keratin fibres without thinning them, thereby imparting good conditioning properties to the keratin fibres.

[0008] In parallel, more and more users of cosmetic products are looking for more aesthetically pleasing or even more original hair hygiene products. Summary of the invention

[0009] There is therefore a real need to develop aesthetic compositions which are stable over time, based on natural and / or biodegradable ingredients, preferably containing no silicones, and which enable excellent washing and processing characteristics to be obtained, in particular in terms of foam onset, quality and quantity of foam produced, and viscosity. These compositions also advantageously impart good conditioning properties to keratin fibres, in particular in terms of feel, smoothness, manageability and detangling.

[0010] These objects are achieved by the present invention, a subject of which is a composition, preferably a cosmetic composition, comprising:

[0011] (i) at least one anionic surfactant,

[0012] (ii) at least one amphoteric or zwitterionic surfactant,

[0013] (iii) at least one glucosamide compound, and

[0014] (iv) at least one cationic galactomannan gum; and

[0015] The weight ratio of the total content of the anionic surfactant (i) to the total content of the amphoteric or zwitterionic surfactant (ii) is less than or equal to 4.3.

[0016] It has been found that the compositions according to the invention have excellent keratin fibre cleaning capabilities.

[0017] In particular, hair treated with the compositions according to the invention is particularly clean and has good cosmetic properties.

[0018] It was also noted that the hair so treated was exceptionally light, soft to the touch, smooth to the touch, supple, easy to detangle and more manageable.

[0019] Furthermore, it has been observed that the compositions according to the invention have good processing qualities, in particular a good onset of foaming and a good quality and quantity of foam.It is very particularly noted that the compositions according to the invention enable a large amount of foam to be generated.

[0020] The composition according to the invention has a viscosity suitable for use as a shampoo.

[0021] Furthermore, it is noted that the compositions according to the invention are particularly stable over time at atmospheric pressure and 25°C.

[0022] More particularly, when the composition according to the invention also comprises at least one sunscreen agent, the composition remains homogeneous and no phase separation phenomena of the composition are observed.

[0023] According to an advantageous embodiment of the invention, the composition according to the invention also comprises one or more particles (such as sunscreens, pigments, flakes, etc. . . ) in the form of a homogeneous and stable suspension.

[0024] The visually stable and homogeneous suspension of these particles significantly improves the aesthetic appearance and originality of the compositions according to the invention.

[0025] For the purposes of the present invention, the expression "stable and homogeneous suspension" is intended to mean that the particles are homogeneously dispersed in the composition, that is to say are evenly distributed within the composition, and that this homogeneous dispersion persists over time, that is to say the particles do not float on the surface, do not flow, do not separate out and / or do not form agglomerates in the composition over time, in particular after storage for at least one week.

[0026] A subject of the present invention is also a process for the treatment, in particular cosmetic 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.

[0400] Examples

[0401] Example 1:

[0402] Compositions A1, A2 and A3 according to the invention were prepared from the ingredients indicated in the table below, the amounts being expressed as percentage by weight of active material (AM).

[0403] [Table 1]

[0404]

[0405] It was observed that the hair treated with one of the compositions A1, A2 and A3 according to the invention was particularly clean, easy to detangle, smooth and soft to the touch.

[0406] Furthermore, compositions A1, A2 and A3 according to the invention produced foam of good quality and in large quantities.

[0407] Example 2:

[0408] Comparative Composition B was prepared from the ingredients indicated in the table below, the amounts of which are expressed as weight percent of active material (am).

[0409] [Table 2]

[0410]

[0411] 2.1 Touch smoothness:

[0412] The hair treated with compositions A1 and A2 of Example 1 (invention) or composition B (comparative) was evaluated for its smoothness properties.

[0413] Compositions A1, A2 and B were each applied at a rate of 0.4 g of composition per gram of hair to 1 g of 27 cm long tresses of moderately sensitized Caucasian hair (AS20).

[0414] Then, the test results were analyzed by a Lloyd Instruments tension-compression tester. The friction force (ie the work of friction in mJ) was measured to evaluate the slippery properties of each (dry or wet) treated hair lock.

[0415] More specifically, the friction force is measured in mJ between the lock of hair to be evaluated (dry or wet) and the two rollers of a tension-compression tester which pass along the lock of hair from root to end at a constant speed and simulate the fingers of a consumer.

[0416] The smoother the hair strand feels, the lower the friction force measured.

[0417] The results are summarized in the table below.

[0418] [Table 3]

[0419]

[0420] It is observed that the hair treated with composition A1 or composition A2 according to the invention exhibits a greater smoothness to the touch than the hair treated with comparative composition B.

[0421] 2.2 Stability:

[0422] The stability of compositions A1 and A2 according to the invention and comparative composition B was evaluated.

[0423] To this end, compositions A1, A2 and B, which are white in color and have a homogeneous appearance, are placed in containers at a temperature of 45° C. and in the dark for 2 months.

[0424] After storage for two months at 45° C., it was noted that compositions A1 and A2 according to the invention maintained a homogeneous appearance and were white in color, without any phase separation.

[0425] After storage at 45°C for two months, it was noted that Comparative Composition B now exhibited phase separation and was brown in color.

[0426] It is clear that compositions A1 and A2 according to the invention exhibit better stability over time than comparative composition B.

[0427] Example 3:

[0428] A sensory evaluation was carried out on hair treated with compositions A1 and A2 of Example 1 (according to the invention).

[0429] Compositions A1 and A2 according to the invention were each applied to locks of moderately sensitized Caucasian hair (AS20) at a rate of 0.4 g of composition per gram of hair.

[0430] The conditioning properties of each treated tress (dry and then wet) were evaluated sensorily by 3 experts. For this purpose, each expert compared one of the tresses treated (with A1 or with A2) with a tress treated with a commercial shampoo containing silicone at the same rate of 0.4 g of composition per gram of hair.

[0431] Each expert then rated the hair locks treated according to the invention according to the following scale:

[0432] +3: Much better than commercial shampoos.

[0433] +2: Much better than commercial shampoos,

[0434] +1: Better than commercial shampoo,

[0435] +0.5: Slightly better than commercial shampoo,

[0436] 0: Similar to hair tresses treated with commercial shampoo,

[0437] -0.5: Slightly worse than commercial shampoo,

[0438] -1: Worse than commercial shampoo,

[0439] The results are summarized in the table below.

[0440] [Table 4]

[0441]

[0442] It is noted that hair treated with compositions A1 or A2 according to the invention exhibits conditioning properties at least equal to, and even superior in certain properties to, hair treated with commercial shampoos based on silicone.

[0443] Example 4:

[0444] Compositions C1, C2 and C3 according to the invention and also comparative composition C' were prepared from the ingredients indicated in the table below, the amounts being expressed as percentages by weight of active material (AM).

[0445] [Table 5]

[0446]

[0447]

[0448] 4.1 Tactile Smoothness and Untangling:

[0449] The above composition was applied in a standardized manner to a pre-wetted moderately sensitized (alkaline solubility = 20%, AS20) tress at a ratio of 1 g / 2.7 g hair while massaging the tress for 15 seconds (6 passes between fingers).

[0450] After a leave-in time of 1 minute, the hair is rinsed for 20 seconds (25 passes between the fingers).

[0451] The hair was then dried and evaluated while still damp.

[0452] The impact of the invention on the performance results in terms of smooth feel was evaluated by 5 experts in a blind test on wet hair on a scale ranging from 0 (poor) to 8 (very good).

[0453] To assess the smoothness, the expert held the lock of hair between the thumb and index finger and slid the finger along the lock from the top to the end.

[0454] Experts evaluated whether the hair was soft, whether it exhibited coarse tufts, whether it caught the fingers and whether it had an even feel.

[0455] The results are summarized in the table below.

[0456] [Table 6]

[0457]

[0458]

[0459] The experts judged that the compositions C1, C2 and C3 according to the invention imparted an improved smoothness compared to the comparative composition C'.

[0460] The effect of the invention on the performance results in terms of detangling was evaluated by 1 expert on wet hair in a blind test on a scale ranging from 0 (poor) to 8 (very good).

[0461] To evaluate detangling, experts rated how easily a fine brush passed through the hair as it slid from roots to ends.

[0462] The results are summarized in the table below.

[0463] [Table 7]

[0464]

[0465] The hair treated with compositions C1, C2 and C3 according to the invention is easier to detangle than the hair treated with the comparative composition C'.

[0466] Example 5:

[0467] The composition D1 according to the invention and the comparative composition D2 were prepared from the ingredients indicated in the table below, the amounts being expressed as percentage by weight of active material (am).

[0468] [Table 8]

[0469]

[0470]

[0471] The above compositions D1 and D2 were applied in a standardized manner to pre-moistened moderately sensitized (alkaline solubility = 20%, AS20) hair tresses at a rate of 1.5 g composition / 1 g hair, while massaging the tresses for 15 seconds.

[0472] The hair was then rinsed with water at 35°C for 10 seconds and then wrung dry.

[0473] The wet hair was then evaluated (detangling and smoothness) and dried in an oven before being evaluated again (smooth to touch).

[0474] 5.1 Untangling of wet hair:

[0475] Run the comb through your hair from root to tip. The sooner the comb gets stuck, the harder it will be to untangle your hair.

[0476] Measure the distance between the root of the hair and where the comb is stuck.

[0477] For the hair treated with composition D1 according to the invention, the comb was caught about 3 cm behind the root (half way through the lock).

[0478] For the hair treated with comparative composition D2, the comb got stuck about 2 cm behind the root (one third of the lock).

[0479] Hair treated with the composition D1 according to the invention is easier to detangle than hair treated with the comparative composition D2.

[0480] 5.2 Smoothness of wet hair:

[0481] The effect of the invention on the performance results in terms of softness was evaluated by 4 experts in a blind test on wet hair on a scale ranging from 0 (poor) to 8 (very good).

[0482] To evaluate the smoothness, the experts take the locks of hair in their hands and try to bend them. The experts assess how easily the hair bends, its malleability.

[0483] The results are summarized in the table below.

[0484] [Table 9]

[0485]

[0486] The hair treated with the composition D1 according to the invention is smoother than the hair treated with the comparative composition D2.

[0487] 5.3 Smoothness of dry hair

[0488] The effect of the invention on the performance results in terms of smooth feel was evaluated by 4 experts in a blind test on dry hair on a scale ranging from 0 (poor) to 8 (very good).

[0489] To evaluate the smoothness, the expert held the lock of hair between the thumb and index finger and slid the finger along the lock from the top (root) to the end.

[0490] Experts evaluated whether the hair was soft, whether it exhibited coarse tufts, whether it caught the fingers and whether it had an even feel.

[0491] The results are summarized in the table below.

[0492] [Table 10]

[0493]

[0494] The experts judged that the composition D1 according to the invention imparted an improved smoothness compared to the comparative composition D2.
