Description

Title of the invention: Cosmetic composition comprising anionic and / or amphoteric surfactants, at least two different cationic surfactants and silicones, and cosmetic processing method

[0001] The present invention relates to a cosmetic composition comprising at least two cationic surfactants different from each other, one or more anionic and / or amphoteric surfactants, and one or more silicones, with a particular weight ratio between the cationic surfactants and the silicones.

[0002] The invention also relates to a cosmetic treatment process for keratinous materials using said composition.

[0003] Hair is sensitive to many types of aggression and can be weakened and damaged to varying degrees by the external environment, in particular by the action of atmospheric agents such as light, air pollution and weathering, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, or even repeated washing.

[0004] The properties of damaged hair are then degraded and various manifestations of damage can be observed, such as difficulties in detangling and styling the hair, lack of softness of the hair, hair which can eventually become dry, brittle or dull, especially in fragile areas, and more particularly at the tips.

[0005] To remedy these drawbacks, it is common to use hair care cosmetic compositions designed to condition the hair by providing it with satisfactory cosmetic properties. These hair care compositions, intended for regular application to the hair, can be, for example, shampoos, conditioners, masks, or serums, and can be in the form of gels, hair lotions, and creams of varying thicknesses. These compositions generally rely on the use of high levels of silicones and offer benefits that are rarely sufficient for the most damaged hair and whose effects are only noticeable at the time of application and in the few hours that follow.

[0006] Although there are many hair repair formulas, they generally do not provide hair with entirely satisfactory and lasting cosmetic properties. Indeed, the benefits provided, such as detangling, smoothness, shine, suppleness, and split end repair, are not always sufficient for the hair The most sensitive individuals experience these effects, or they are accompanied by a feeling of heaviness. Moreover, these benefits diminish rapidly over time.

[0007] In addition, the use of high levels of silicone may be perceived unfavorably by consumers.

[0008] The present invention therefore aims to provide cosmetic compositions for the treatment of keratinous materials, particularly for hair conditioning. This composition comprises low levels of silicone, relative to the content of cationic surfactant-type conditioning agents. The composition is effective in providing cosmetic properties to the hair, both at the time of application and over time. Furthermore, the composition is characterized by pronounced conditioning and repair benefits while maintaining a feeling of lightness and cleanliness.

[0009] The invention therefore aims in particular to offer a composition capable of providing significant care and lightness properties from the moment of application until the next shampoo, using low levels of silicones.

[0010] The present invention relates to a cosmetic composition comprising: - one or more surfactants selected from anionic surfactants and amphoteric surfactants,

[0011] - at least two cationic surfactants different from each other, and

[0012] - one or more silicones,

[0013] the weight ratio between the total content of cationic surfactants and the total content of silicone(s) being greater than or equal to 7.

[0014] It has been observed that the composition according to the invention rinses easily, and after application gives a good level of care, as well as a clean feel, without weighing down, to the hair; these effects are lasting for at least 24 hours and can persist after shampooing.

[0015] The observed cosmetic performance, in particular of easier detangling, superior lasting smoothness to the touch, increased suppleness, improved care / nutrition, coating quality, repair in particular of the ends, protection against breakage, and prevention of frizz, can advantageously be obtained with a low silicone content, in particular a lower content than the content usually used.

[0016] In this description, and unless otherwise indicated: - the expression "at least one" is equivalent to the expression "one or more" and can be substituted for it; - the expression "between" is equivalent to the expression "ranging from" and can be substituted for it, and implies that the limits are included.

[0424] It is also possible to use microwaxes in the compositions of the invention;Examples include camauba microwaxes, such as the one marketed under the name MicroCare 350® by MICRO POWDERS; synthetic wax microwaxes, such as the one marketed under the name MicroEase 114S® by MICRO POWDERS; microwaxes made from a mixture of camauba wax and polyethylene wax, such as those marketed under the names Micro Care 300® and 310® by MICRO POWDERS; microwaxes made from a mixture of camauba wax and synthetic wax, such as the one marketed under the name Micro Care 325® by MICRO POWDERS; polyethylene microwaxes, such as those marketed under the names Micropoly 200®, 220®, 220L® and 250S® by MICRO POWDERS; and polytetrafluoroethylene microwaxes, such as those marketed under the names Microslip 519® and 519 L® by the company MICRO POWDERS. ;

[0425] Waxes are preferably chosen from mineral waxes such as paraffin wax, petrolatum, lignite or ozokerite; vegetable waxes such as cocoa butter, shea butter or waxes from cork or sugar cane fibers, olive wax, rice bran wax, hydrogenated jojoba wax, Ouricoury wax, Camauba wax, Candelila wax, Alfa wax, or absolute flower waxes such as blackcurrant flower essential wax sold by the BERTIN company (France); the waxes of animal origin such as beeswax or modified beeswax (cerabellina), spermaceti, lanolin wax and lanolin derivatives; microcrystalline waxes; and mixtures thereof.

[0426] Butters can also be used as a solid fat.

[0427] For the purposes of this invention, "butter" (also referred to as "pasty fat") means a lipophilic fatty compound with a reversible solid / liquid phase change, comprising a liquid fraction and a solid fraction at a temperature of 25°C and atmospheric pressure (760 mm Hg). Preferably, the butter(s) according to the invention have a melting point above 25°C and a melting point below 60°C.

[0428] Preferably the particular butter(s) are of vegetable origin such as those described in Ullmann's Encyclopedia of Industrial Chemistry (“Fats and Fatty Oils”, A. Thomas, Published Online: 15 JUN 2000, DOI: 10.1002 / 14356007.al0_173, point 13.2.2.2. Shea Butter, Borneo Tallow, and Related Fats (Vegetable Butters)).

[0429] We can mention in particular shea butter, Nilotica Shea butter (Butyrospermum parkii), Galam butter (Butyrospermum parkii), Borneo butter or fat (tengkawang tallow) (Shorea stenoptera), Shorea butter, Illipe butter, Madhuca or Bassia Madhuca longifolia butter, mowrah butter (Madhuca Latifolia), Katiau butter (Madhuca mottleyana), Phulwara butter (M.butyracea), mango butter (Mangifera indica), Murumuru butter (Astrocaryum murumuru), Kokum butter (Garcinia Indica), Ucuuba butter (Virola sebifera), Tucuma butter, Painya (Kpangnan) butter (Pentadesma butyracea), coffee butter (Coffea arabica), apricot butter (Prunus Armeniaca), macadamia butter (Macadamia Ternifolia), grape seed butter (Vitis vinifera), avocado butter (Persea gratissima), olive butter (Olea europaea), sweet almond butter (Prunus amygdalus dulcis) and cocoa butter, sunflower butter.

[0430] Shea butter is an example of a preferred butter. It is well known that shea butter is extracted from the fruit (also called "almonds" or "nuts") of the Butyrospemim Parkii tree. Each fruit contains between 45 and 55% fat, which is extracted and generally refined. Shea butter contains triglycerides of fatty acids. The fatty acid composition of shea butter varies, particularly depending on the geographical origin of the nuts, with stearic and oleic acids being by far the most abundant and generally exceeding 80% by weight relative to the total weight of fatty acids.

When present in the composition according to the invention, the organic solvent(s) generally represent 0.1 to 15% by weight, preferably 0.5 to 10% by weight, and more preferably 1 to 5% by weight, of the total weight of the composition.

[0445] The cosmetic composition according to the present invention may possibly further include one or more additives, different from the compounds of the invention and among which we may mention non-ionic surfactants, cationic, anionic, non-ionic, amphoteric polymers or mixtures thereof, non-siliconized liquid fats, anti-dandruff agents, anti-seborrheic agents, vitamins and provitamins including panthenol, sunscreens, sequestering agents, plasticizers, solubilizing agents, acidifying agents, mineral or organic thickening agents, in particular polymeric thickening agents, opacifying or pearlescent agents, antioxidants, hydroxy acids, perfumes, preservatives, and fillers. Naturally, a person skilled in the art will ensure that any additional compound(s) are chosen in such a way that the advantageous properties intrinsic to the composition according to the invention are not, or not substantially, altered by the envisaged addition(s). The above-mentioned additives may generally be present in quantities ranging from 0 to 20% by weight of each, relative to the total weight of the composition.

[0446] The invention also relates to a cosmetic treatment process for keratinous materials, in particular human keratinous fibers such as hair, comprising the application to said keratinous materials of a composition as defined above. The composition according to the invention can be applied to dry or wet keratinous materials, possibly having been washed with shampoo.

[0447] Preferably, the composition according to the invention is applied to moist keratin fibers.

[0448] After a possible setting time of 1 to 15 minutes, preferably 2 to 10 minutes, the keratin fibers can then be rinsed, for example with water, before being dried or left to dry.

[0449] The cosmetic treatment process for keratinous materials is preferably a hair conditioning process.

[0450] The composition according to the invention is preferably in the form of a rinse-out conditioner or a rinse-out hair mask, but can also be in the form of a leave-in hair care composition such as a leave-in conditioner or a hair serum.

[0451] The following examples serve to illustrate the invention without, however, being intended to be limiting.

[0452] In the following examples, all quantities are given, unless otherwise indicated, as a mass percentage of active material (AM) relative to the total weight of the composition.

[0453] Example 1 Compositions A to D according to the invention were prepared from the following ingredients (% MA):

[0454] [Tables 1] ABCD Amodimethicone (DOWSIL AP-8568 AMINO FLUID from Dow Corning) 0.2 0.2 0.2 0.2 Behentrimonium chloride 0.8 1.0 1.0 - Stearamidopropyl dimethylamine - - - 0.95 Dipalmitoylethyl hydroxyethylmonium methosulfate 1.0 1.0 1.0 1.0 Cocobetaine 0.02 0.02 - 0.02 Sodium laureth sulfate - - 0.015 - Cetearyl alcohol 4.7 4.6 4.6 4.6 Cetyl esters 0.4 0.4 0.4 0.4 Glycerin - 2 - - pH agent (pH = 4.1 ± 0.5) Qs Qs Qs Qs Preservatives Qs Qs Qs Qs Water Qsp 100 Qsp 100 Qsp 100 Qsp 100 Ratio of cationic surfactants / silicone 9 10 10 9.5

[0455] Compositions are obtained that can be used as a rinse-off hair care product (conditioning conditioner).

[0456] These compositions provide good cosmetic (conditioning) properties to the hair, in particular in terms of smoothness to the touch, detangling and shine; they also provide repair benefits, while leaving the hair light.

[0457] Composition A according to the invention was tested against a commercial conditioner for damaged hair.

[0458] A panel of testers, regular users of conditioning hair products for dry, damaged or colored hair, tested for 2 weeks either composition A according to the invention, or the commercial conditioner for damaged hair.

[0459] Composition A (or the commercial conditioner) was used in the usual way (application, setting, rinsing, drying), after the use of a commercial shampoo.

[0460] After 2 weeks of use, the testers indicated whether they were agree / completely agree with the proposed performance criterion.

[0461] The following results were obtained (% of testers agree / strongly agree with the performance criterion):

[0462] [Tables2] Performance criterion A (invention) A' (trade) Hair smooth to the touch 80% 64% Hair shiny 91% 85% Hair feels light until the next shampoo 94% 83% Ease of detangling 94% 89% Protects against breakage 88% 76% Makes hair stronger and more resilient 87% 79%

[0463] It can be seen that for each of the criteria, the difference is significantly in favor of the composition according to the invention. It thus provides significantly superior care (detangling, smoothing, shine) and repair (protection against breakage, strengthening of the hair) benefits compared to a commercially available composition specifically designed for damaged hair. It also provides the added benefit of lasting lightness.

[0464] Example 2 Compositions E according to the invention and comparative E' were prepared from the following ingredients (% MA):

[0465] [Tables3] E E' Amodimethicone (DOWSIL AP-8568 AMINO FLUID from Dow Corning) 0.2 0.2 Behentrimonium chloride 0.9 0.9 Dipalmitoylethyl hydroxyethylmonium methosulfate 1.0 1.0 Sodium laureth sulfate 0.04 - Cetearyl alcohol 4.6 4.6 Cetyl esters 0.4 0.4 pH agent (pH = 4.1 ± 0.5) Qs Qs Preservatives Qs Qs Water Qsp 100 Qsp 100

[0466] Compositions are obtained that can be used as hair care products at rinse (conditioner). Evaluation of the homogeneity of the deposit

[0467] The compositions are tested on strands of moderately sensitized Caucasian hair (SA20), 1 g and 27 cm in length.

[0468] Initially, the strands are cleaned using a standard silicone-free shampoo (DOP Chamomile), at a rate of 0.4 g of shampoo per g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0469] In a second step, the composition to be tested is applied to the wet strands at a rate of 0.4 g / g of hair, before a time of 5 minutes followed by a 10 second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0470] The homogeneity of the silicone deposit on wet hair is evaluated by measuring the friction forces of the treated strand from the length to the tip of the hair, during its movement at constant speed, between two cylinders, while squeezing it at constant compression.

[0471] The difference in friction forces between the body of the strand and the tip of the strand is determined to characterize the quality of the coating. The smaller the difference, the more homogeneous the coating is over the entire hair, resulting in a smoother, higher-quality feel.

[0472] The following results are obtained (average of measurements taken on 6 strands):

[0473] [Tables4] E (invention) E' (comparative) Gap (Points Length) 80 140

[0474] The difference in friction forces measured on wet hair, between the body of the strand and the tip, is significantly lower for strands treated with the composition according to the invention.

[0475] The surface deposit provided by the composition according to the invention therefore appears to be more homogeneous and gives a better quality of smoothness to the touch over the whole of the hair. Sensory evaluation

[0476] The tests are carried out on strands of moderately sensitized Caucasian hair (SA20), weighing 2.7 g and measuring 27 cm in length. The strands are pre-cleaned with a standard shampoo (DOP Chamomile) at a rate of 0.4 g / g of hair.

[0477] Each strand is then treated with a classic repair shampoo (ELSEVE Total Repair 5, L'Oréal Paris) at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, left on for 15 seconds, then rinsed with water for 10 seconds (flow rate: 300 l / h, temperature: 35°C).

[0478] In a second step, the composition to be tested is applied to damp hair at a rate of 0.4 g / g of hair, left on for 2 minutes, then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35°C). The hair is towel-dried and then evaluated while damp. Finally, the strands are blow-dried and then evaluated (dry).

[0479] Detangling is assessed using a comb, while smoothness and coating are noted by touch. The scores range from 0 (no performance) to 5 (maximum performance).

[0480] Evaluation of smoothness by touch: the evaluator takes a strand of hair at the root and runs it between their fingers along its entire length to the tips. The more uniform and homogeneous the hair is from root to tip, the fewer rough edges it has, the less it catches the fingers, and the better the smoothness by touch.

[0481] Coating assessment: the assessor takes the strand of hair in their hand, starts at the root and slides it to the tips. The more a deposit is felt on the fiber, the better the coating.

[0482] Detangling assessment: Detangling is assessed using a comb that the assessor slides from root to tip. The more easily the comb slides, the better the detangling.

[0483] The following results are obtained:

[0484] [Tables5] Evaluated criterion E (invention) E' (comparative) Wet hair Ease of detangling 4.5 3.5 Smoothness to the touch 4 3 Coating 4 3 Dry hair Smoothness to the touch 4 3 Coating 4 3

[0485] It is observed that the composition according to the invention comprising an anionic surfactant is significantly superior across all the criteria tested, compared to the composition without anionic surfactant. This superiority is manifested on wet hair by greater ease of detangling, smoother hair to the touch, and a more pronounced coating indicating better fiber transformation. On dry hair, the hair appears more treated (more conditioning coating). important) and softer (smoother, superior feel)

[0486] Example 3 Compositions F according to the invention and comparative F' were prepared from the following ingredients (% MA):

[0487] [Tableauxô] F F' Amodimethicone (DOWSIL AP-8568 AMINO FLUID from Dow Corning) 0.24 0.71 Behentrimonium chloride 1.2 1.2 Dipalmitoylethyl hydroxyethylmonium methosulfate 1.3 1.3 Cocobetaine 0.03 0.03 Cetearyl alcohol 5.2 5.2 Cetyl esters 0.4 0.4 pH agent (pH = 4.1 ± 0.5) Qs Qs Preservatives Qs Qs Water Qsp 100 Qsp 100 Ratio of cationic surfactants / silicone 10.4 3.5

[0488] Compositions are obtained that can be used as a rinse-off hair care product (conditioning conditioner). Hair application

[0489] The compositions are tested on strands of natural Caucasian hair, 2.7 g and 27 cm in length.

[0490] Initially, the strands are cleaned using a standard silicone-free shampoo (DOP Chamomile) at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0491] In a second step, the composition to be tested is applied to damp hair at a rate of 0.4 g / g of hair, left on for 2 minutes followed by a 15-second rinse with water (flow rate: 300 l / h, temperature: 35°C). Finally, the strands are dried for 30 minutes in an oven at 60°C.

[0492] The standard shampoo application cycle + composition to be tested + oven drying is repeated 4 more times.

[0493] The deposition of silicone on hair is quantified by X-ray fluorescence spectrometry via the measurement of the mass concentration of silicon on the fiber capillary. We subtract from the measurement obtained on the treated hair the amount of silicon naturally present in the untreated hair (silicon deposit = content measured on treated hair - content measured on untreated hair).

[0494] The following results are obtained (silicon deposition measured by XRF on dry hair, treated in multi-application (x5) with compositions F or F'. The values ​​are expressed in pg of silicon element per g of hair):

[0495] [Tables?] Silicon Deposition F (invention) F' (comparative) Average value 251 33 Standard deviation 50 24

[0496] It is observed that the composition according to the invention leads to a significantly higher silicone deposition on the hair than the comparative composition, although it comprises a lower concentration of silicone. Sensory evaluation

[0497] The tests are carried out on strands of moderately sensitized Caucasian hair (SA20), weighing 2.7 g and measuring 27 cm in length. The strands are pre-cleaned with a standard shampoo (DOP Chamomile) at a rate of 0.4 g / g of hair.

[0498] Each strand is then treated with a classic repair shampoo (ELSEVE Total Repair 5, L'Oréal Paris) at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0499] In a second step, the composition to be tested is applied to damp hair at a rate of 0.4 g / g of hair, left for 2 minutes followed by a 15-second rinse with water (flow rate: 300 l / h, temperature: 35°C). The hair is then towel-dried and evaluated while wet. Finally, the strands are blow-dried and evaluated (dry).

[0500] Detangling is assessed using a comb (by 1 evaluator) while smoothness is noted by touch (by 4 evaluators). Scores range from 0 (no performance) to 5 (maximum performance).

[0501] The following results are obtained:

[0502] [Tables8] Evaluated criterion F (invention) F' (comparative) Wet hair Ease of detangling 4.5 4.0 Smoothness to the touch 3.8 ± 0.2 2.5 ± 0.6 Dry hair Smoothness to the touch 4.2 ± 0.3 3.3 ± 0.4

[0503] It is observed that the composition according to the invention facilitates detangling and provides superior hair smoothing performance in both wet and dry conditions, significantly superior to that of the comparative composition, although it contains less silicone.

[0504] Instrumental evaluation of smoothing performance

[0505] The compositions are tested on strands of moderately sensitized Caucasian hair (SA20), 1 g and 27 cm in length.

[0506] Initially, the strands are cleaned using a standard silicone-free shampoo (DOP Chamomile), at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35 °C).

[0507] In a second step, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair, before a time of 5 minutes followed by a 15 second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0508] The friction forces on dry hair are measured, from the length to the tip of the treated strand, during its movement at constant speed between two cylinders, while it is clamped under constant compression. Low friction forces reflect a smoother hair surface.

[0509] The following results are obtained (average of measurements taken on 6 strands):

[0510] [Tables9] Friction forces (mJ) F (invention) F' (comparative) Average friction force 143.4 164.5 Standard deviation 5.6 6.6

[0511] It is observed that the composition according to the invention makes it possible to significantly reduce the friction forces on dried hair compared to the comparative composition, although it includes a lower silicone content.

[0512] A cationic surfactant / silicone ratio greater than or equal to 7 can therefore allow to significantly increase the effectiveness of silicone deposition on the hair and to obtain added value on sensory qualities and detangling, as well as a significant gain on the performance of the hair smoothness criterion.

[0513] Example 4 Compositions G according to the invention and comparative G' were prepared from the following ingredients (% MA):

[0514] [TableauxlO] G G' Amodimethicone (DOWSIL AP-8568 AMINO FLUID from Dow Corning) 0.17 0.17 Behentrimonium chloride 0.95 0.95 Dipalmitoylethyl hydroxyethylmonium methosulfate 1.0 1.0 Cocobetaine 0.02 - Cetearyl alcohol 4.6 4.6 Cetyl esters 0.4 0.4 pH agent (pH = 4.1 ± 0.5) Qs Qs Preservatives Qs Qs Water Qsp 100 Qsp 100

[0515] Compositions are obtained that can be used as a rinse-off hair care product (conditioning conditioner). Hair application

[0516] The compositions are tested on strands of natural Caucasian hair, 2.7 g and 27 cm in length.

[0517] Initially, the strands are cleaned using a standard silicone-free shampoo (DOP Chamomile) at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0518] In a second step, the composition to be tested is applied to damp hair at a rate of 0.4 g / g of hair, left on for 2 minutes followed by a 15-second rinse with water (flow rate: 300 l / h, temperature: 35°C). Finally, the strands are dried for 30 minutes in an oven at 60°C.

[0519] The deposition of silicone on hair is quantified by X-ray fluorescence spectrometry via the measurement of the mass concentration of silicon on the hair fiber. The amount of silicon naturally present in untreated hair is subtracted from the measurement obtained on treated hair (silicon deposition = content measured on treated hair - content measured on untreated hair).

[0520] The following results are obtained (silicon deposition measured by XRF on dry hair treated with compositions G or G'. The values ​​are expressed in pg of element silicon per gram of hair.

[0521] [Tables 11] G (invention) G' (comparative) Silicon deposition 220 194 Standard deviation 16 61

[0522] It is observed that the composition according to the invention leads to a higher deposition of silicone on the hair than the comparative composition. Sensory evaluation

[0523] The tests are carried out on strands of moderately sensitized Caucasian hair (SA20), weighing 2.7 g and measuring 27 cm in length. The strands are pre-cleaned with a standard shampoo (DOP Chamomile) at a rate of 0.4 g / g of hair.

[0524] Each strand is then treated with a classic repair shampoo (ELSEVE Total Repair 5, L'Oréal Paris) at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0525] In a second step, the composition to be tested is applied to damp hair at a rate of 0.4 g / g of hair, left for 2 minutes followed by a 15-second rinse with water (flow rate: 300 l / h, temperature: 35°C). The hair is then towel-dried and evaluated while wet. Finally, the strands are blow-dried and evaluated (dry).

[0526] Detangling is assessed using a comb, while smoothness and coating are noted by touch. The scores range from 0 (no performance) to 5 (maximum performance).

[0527] The following results are obtained:

[0529] It is observed that the composition according to the invention comprising an amphoteric surfactant is significantly superior on all the criteria tested, to the com Formulated without amphoteric surfactants. This superiority is evident on damp hair as it is easier to detangle, feels smoother, and has a more pronounced coating, indicating better fiber transformation. On dry hair, the hair appears more treated (greater conditioning coating) and softer (superiorly smooth feel).

[0533] The tests are carried out on strands of moderately sensitized Caucasian hair (SA20), weighing 2.7 g and measuring 27 cm in length. The strands are pre-cleaned with a standard shampoo (DOP Chamomile) at a rate of 0.4 g / g of hair.

[0534] Each strand is then treated with a classic repair shampoo (ELSEVE Total Repair 5, L'Oréal Paris) at a rate of 0.4 g / g of hair. The shampoo is massaged onto the strand to create a lather, before a 15-second application time, followed by a 10-second rinse with water (flow rate: 300 l / h, temperature: 35°C).

[0535] In a second step, the composition to be tested is applied to damp hair at a rate of 0.4 g / g of hair, before a processing time of 2 minutes followed by rinsing at The hair is rinsed for 15 seconds (flow rate: 300 l / h, temperature: 35°C). The hair is then towel-dried and assessed as wet. Finally, the strands are blow-dried and assessed as dry.

[0536] Detangling is assessed using a comb (1 assessor) while smoothness and coating are noted by touch (3 assessors). The scores range from 0 (no performance) to 5 (maximum performance).

[0537] The following results are obtained:

[0538] [Tables 14] Evaluated criterion H (invention) H' (comparative) Wet hair Ease of detangling 5.0 4.0 Smoothness to the touch 4.4 ± 0.3 3.0 ± 0.0 Coating 3.9 ± 0.3 3.0 ± 0.0 Dry hair Smoothness to the touch 4.0 ± 0.4 3.0 ± 0.0 Coating 4.3 ± 0.3 3.0 ± 0.5

[0539] It is observed that the composition according to the invention is significantly superior on all the criteria tested, to the comparative composition.

[0540] It provides superior usability qualities (ease of detangling) and better cosmetic performance on wet and dry hair (smooth to the touch, coating).
