Description

[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, the cationic surfactants and the silicones having a specific weight ratio.

[0002] The invention also relates to a method for the cosmetic treatment of keratin materials using said composition.

[0003] Hair is sensitive to various types of aggression and can be brittle and damaged to varying degrees by the action of the external environment, in particular by atmospheric factors such as light, atmospheric pollution and bad weather, and also by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, permanent waving and / or relaxing, or even repeated washing.

[0004] The properties of damaged hair are then degraded and various manifestations of damage are seen, such as difficulty in detangling and styling the hair, the hair lacks softness, the hair may become dry, brittle or dull over time, especially in brittle areas, and more specifically at the ends.

[0005] In order to overcome these drawbacks, it is common practice to use hair compositions for conditioning the hair by imparting to them satisfactory cosmetic properties. These hair care compositions intended to be regularly applied to the hair may be, for example, shampoos, conditioners, masks or serums and may be in the form of gels, hair lotions or treatment creams, which are more or less thick. These compositions are generally based on the use of high levels of silicones and offer benefits which are rarely sufficient for the most damaged hair and which are visible only at the time of application and only for a few hours after said application.

[0006] Although there are many treatment formulas for hair repair, they usually do not impart fully satisfactory and lasting cosmetic properties to the hair. In fact, the benefits provided, such as detangling, smoothness, shine, flexibility, or repair of ends, are not always sufficient for the most sensitive hair or are accompanied by a long and greasy (lank) feeling. In addition, these benefits decrease rapidly over time.

[0007] Furthermore, the use of high silicone levels may be viewed as a disadvantage by consumers.

[0008] The object of the present invention is therefore to provide a cosmetic composition for treating keratin materials, in particular for conditioning the hair, comprising a low silicone content relative to the content of conditioning agents of the cationic surfactant type, said composition being effective in imparting cosmetic properties to the hair both at the time of application and over a period of time that lasts over time. The composition is also characterized by very pronounced care and repair benefits, while maintaining added value in terms of brightness and cleanliness.

[0009] The object of the present invention was therefore in particular to propose a composition which, with a low silicone content, provides outstanding conditioning and shine properties immediately after its application until the next shampoo wash.

[0010] The subject of the present invention is a cosmetic composition comprising:

[0011] - one or more surfactants selected from anionic surfactants and amphoteric surfactants,

[0012] - at least two cationic surfactants that are different from each other, and

[0013] - one or more silicones,

[0014] The weight ratio between the total content of cationic surfactants and the total content of silicone is greater than or equal to 7.

[0015] It should be noted that the composition according to the invention rinses off easily and, after application, imparts a good level of hair conditioning and also a clean feel without leaving the hair feeling long and greasy; these effects last at least 24 hours and may persist after shampooing.

[0016] The observed cosmetic performance results, particularly in terms of easier detangling, longer lasting smooth feel, increased flexibility, improved care / nourishment provided, coating quality, repair (particularly end repair), prevention of breakage and prevention of frizz, can advantageously be achieved at low silicone levels, particularly levels below those typically used.

[0017] In this specification, and unless otherwise indicated:

[0018] - the expression "at least one" is equivalent to the expression "one or more" and can be replaced by it;

[0019] - the expression "between" is equivalent to and can be replaced by the expression "ranging from..." and means that the limit values ​​are included;

The above additives may each be present in an amount generally between 0% and 20% by weight relative to the total weight of the composition.

[0510] A subject of the present invention is also a process for the cosmetic treatment of keratin materials, especially human keratin fibres such as the hair, which comprises applying to said keratin materials a composition as defined above.

[0511] The composition according to the invention can be applied to dry keratin material or to wet keratin material which has optionally been shampooed.

[0512] Preferably, the composition according to the invention is applied to wet keratin fibres.

[0513] After an optional leave-on time, which may range from 1 to 15 minutes, preferably from 2 to 10 minutes, the keratin fibres may then be rinsed, for example with water, and then dried or air-dried.

[0514] The method for the cosmetic treatment of keratin materials is preferably a hair conditioning method.

[0515] The composition according to the invention is preferably in the form of a rinse-off conditioner or a rinse-off mask, but can also be in the form of a leave-in hair product or a hair serum.

[0516] The following examples serve to illustrate the invention but are not limiting in nature.

[0517] In the following examples, unless otherwise stated, all amounts are given as mass percentages of active material (AM) relative to the total weight of the composition.

[0518] Example 1

[0519] Compositions A to D according to the invention are prepared from the following ingredients (% AM):

[0520] [Table 1]

[0521]

[0522] A composition is obtained which can be used as a rinse-out hair care product (conditioner).

[0523] These compositions impart good cosmetic properties (conditioning properties) to the hair, especially in terms of smooth feel, detangling and shine; they also impart repair benefits while making the hair shiny.

[0524] Composition A according to the invention was tested against a commercial hair conditioner on damaged hair.

[0525] A panel of test persons, regular users of conditioning hair products for dry, damaged or coloured hair, tested composition A according to the invention, or a commercial hair conditioner, on dry hair, for 2 weeks.

[0526] After using the commercial shampoo, use Composition A (or commercial conditioner) in the normal manner (application, leave-on time, rinse, dry).

[0527] After 2 weeks of use, testers indicated that they agreed / strongly agreed with the performance criteria presented.

[0528] The following results were obtained (% of testers who agreed / strongly agreed with the performance criteria):

[0529] [Table 2]

[0530] Performance Standards A (the present invention) A'(Business) Smooth feel to hair 80％ 64％ Shiny hair 91％ 85％ Hair is shiny until next shampooing 94％ 83％ Easy to untangle 94％ 89％ Protection from breakage 88％ 76％ Makes hair stronger and healthier 87％ 79％

[0531] It should be noted that for each of the criteria, the composition according to the invention has a clear difference. Thus, it is possible to provide care benefits (detangling, smoothness, shine) and repair benefits (protection from breakage, strong hair) significantly greater than commercially available compositions specifically intended for damaged hair. It also provides the added value of long-lasting shine.

[0532] Example 2

[0533] Composition E according to the invention and comparative composition E' were prepared from the following ingredients (% AM):

[0534] [Table 3]

[0535]

[0536] A composition is obtained which can be used as a rinse-off hair care product (conditioner).

[0537] Evaluation of sediment uniformity

[0538] The compositions were tested on tresses of medium sensitized Caucasian hair (SA20) of 1 g and 27 cm in length.

[0539] First, the tresses were cleaned with a standard silicone-free shampoo (DOP Camomile) at a rate of 0.4 g shampoo / g hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0540] Secondly, the composition to be tested is applied to the wet tresses at a rate of 0.4 g / g of hair and then, after a dwell time of 5 minutes, rinsed with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0541] The uniformity of the silicone deposition is evaluated on wet hair by measuring the friction on the treated hair tresses along the length of the hair to the ends during squeezing between two rollers moving at a constant speed at the same time at a constant compression.

[0542] The difference in friction between the body of the lock and the end of the lock is determined in order to establish the quality of the deposit. The smaller the difference, the more even the deposit throughout the hair, reflecting a more textured, smooth feel.

[0543] The following results were obtained (mean value of measurements, performed on 6 tresses):

[0544] [Table 4]

[0545] E (the present invention) E'(Comparison) <![CDATA[Difference (F 末端 – F 长度 )]]> 80 140

[0546] The difference in friction between the body and the ends of the tresses measured on wet hair is significantly smaller for the tresses treated with the composition according to the invention.

[0547] Thus, the surface deposit provided by the composition according to the invention appears more uniform and imparts a better smooth feel quality throughout the hair.

[0548] Sensory evaluation

[0549] The test was carried out on tresses of medium sensitized Caucasian hair (SA20) of 2.7 g and 27 cm in length. The tresses were pre-cleaned with a standard shampoo (DOP Camomile) at a rate of 0.4 g / g hair.

[0550] Each tress was then treated with a conventional repair shampoo (ELSEVE Total Repair 5, L'Oréal Paris) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0551] Secondly, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair and then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.) after a dwell time of 2 minutes. The hair is wrung out and then evaluated while wet. Finally, the tresses are dried with a hair dryer and then evaluated (dry).

[0552] Detangling was evaluated using a comb, while slipperiness and coating were scored based on feel. Scores ranged from 0 (lack of performance) to 5 (maximum performance).

[0553] Evaluation of smoothness: The evaluator takes a lock of hair at the root and slides it through the fingers over the entire length of the lock, as far as the ends. The more uniform the hair is, the more uniform it is from the root to the ends, the fewer bumps it exhibits, the less it catches on the fingers, the better the smoothness.

[0554] Evaluation of the coating: The evaluator takes the lock of hair in his hand, starts from the roots and slides as far as the ends. The more deposit on the fibers, the better the coating.

[0555] Evaluation of detangling: Detangling is evaluated using a comb that the evaluator glides from the roots to the ends of the hair. The easier the comb glides, the better the detangling.

[0556] The following results were obtained:

[0557] [Table 5]

[0558]

[0559] It should be noted that the composition according to the invention comprising anionic surfactants is significantly superior in all criteria tested compared to the composition without anionic surfactants. This superiority manifests itself on wet hair by easier detangling, smoother feeling hair and more coating present, signifying a better transformation of the fiber. On dry hair, the hair looks more improved (more conditioning coating) and softer (smoother feel).

[0560] Example 3

[0561] Composition F according to the invention and comparative composition F' were prepared from the following ingredients (% AM):

[0562] [Table 6]

[0563]

[0564] A composition is obtained which can be used as a rinse-off hair care product (conditioner).

[0565] Deposits on hair

[0566] The compositions were tested on tresses of natural Caucasian hair of 2.7 g and 27 cm in length.

[0567] First, the tresses were cleaned with a standard silicone-free shampoo (DOP Camomile) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0568] Secondly, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair and then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.) after a dwell time of 2 minutes. Finally, the tresses are dried in an oven at 60° C. for 30 minutes.

[0569] The cycle of applying standard shampoo + composition to be tested + drying in the oven was repeated 4 more times.

[0570] The silicone deposition on the hair was quantified by measuring the mass concentration of elemental silicon on the hair fibers by X-ray fluorescence spectroscopy. The amount of silicon naturally present in untreated hair was subtracted from the measured value obtained on the treated hair (silicon deposition = content measured on treated hair - content measured on untreated hair).

[0571] The following results were obtained (silicon deposits measured by XRF on dry hair treated by multiple applications (×5) of composition F or F′. The values ​​are expressed in μg elemental silicon / g hair):

[0572] [Table 7]

[0573] Silicon deposits F (the present invention) F'(Comparison) average value 251 33 Standard Deviation 50 24

[0574] It should be noted that the composition according to the invention leads to a significantly higher silicone deposit on the hair than the comparative composition, even though it comprises a lower silicone concentration.

[0575] Sensory evaluation

[0576] The test was carried out on tresses of medium sensitized Caucasian hair (SA20) of 2.7 g and 27 cm in length. The tresses were pre-cleaned with a standard shampoo (DOP Camomile) at a rate of 0.4 g / g hair.

[0577] Each tress was then treated with a conventional repair shampoo (ELSEVE Total Repair 5, L'Oreal Paris) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0578] Secondly, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair and then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.) after a dwell time of 2 minutes. The hair is wrung out and then evaluated while wet. Finally, the tresses are dried with a hair dryer and then evaluated (dry).

[0579] Detangling was assessed using a comb (by 1 assessor) and smoothness was scored by feel (by 4 assessors). The scores ranged from 0 (lack of performance) to 5 (maximum performance).

[0580] The following results were obtained:

[0581] [Table 8]

[0582]

[0583] It should be noted that the composition according to the invention favours detangling and confers performance advantages in terms of smoothness of the hair both in wet and dry conditions which are significantly superior to those of the comparative composition, even though it comprises less silicone.

[0584] Instrumental evaluation of lubricity

[0585] The compositions were tested on tresses of medium sensitized Caucasian hair (SA20) of 1 g and 27 cm in length.

[0586] First, the tresses were cleaned with a standard silicone-free shampoo (DOP Camomile) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0587] Secondly, the composition to be tested was applied to wet hair at a rate of 0.4 g / g hair and then, after a dwell time of 5 minutes, rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0588] The friction of the treated lock of hair is measured along the length of the hair and as far as the end, during its movement between two rollers at a constant speed while squeezing them at a constant compression. A low friction reflects a smoother surface state of the hair.

[0589] The following results were obtained (mean value of measurements, performed on 6 tresses):

[0590] [Table 9]

[0591] Friction (mJ) F (the present invention) F'(Comparison) The average friction 143.4 164.5 Standard Deviation 5.6 6.6

[0592] It should be noted that the composition according to the invention makes it possible to significantly reduce the friction on dry hair compared to the comparative composition, even though it comprises a lower silicone content.

[0593] Therefore, a cationic surfactant / silicone ratio greater than or equal to 7 makes it possible to significantly increase the efficiency of silicone deposition on the hair and to obtain added value as regards sensory and detangling qualities, and also a significant gain in performance in terms of the smoothness criterion of the hair.

[0594] Example 4

[0595] Composition G according to the invention and comparative composition G' were prepared from the following ingredients (% AM):

[0596] [Table 10]

[0597]

[0598] A composition is obtained which can be used as a rinse-out hair care product (conditioner).

[0599] Deposits on hair

[0600] The compositions were tested on tresses of natural Caucasian hair of 2.7 g and 27 cm in length.

[0601] First, the tresses were cleaned with a standard silicone-free shampoo (DOP Camomile) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0602] Secondly, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair and then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.) after a dwell time of 2 minutes. Finally, the tresses are dried in an oven at 60° C. for 30 minutes.

[0603] The silicone deposition on the hair was quantified by measuring the mass concentration of elemental silicon on the hair fibers by X-ray fluorescence spectroscopy. The amount of silicon naturally present in untreated hair was subtracted from the measured value obtained on the treated hair (silicon deposition = content measured on treated hair - content measured on untreated hair).

[0604] The following results were obtained (silicon deposits measured by XRF on dry hair treated with composition G or G′). The values ​​are expressed in μg elemental silicon / g hair.

[0605] [Table 11]

[0606] G (present invention) G'(Comparison) Silicon deposits 220 194 Standard Deviation 16 61

[0607] It should be noted that the composition according to the invention leads to a greater silicone deposit on the hair than the comparative composition.

[0608] Sensory evaluation

[0609] The test was carried out on tresses of medium sensitized Caucasian hair (SA20) of 2.7 g and 27 cm in length. The tresses were pre-cleaned with a standard shampoo (DOP Camomile) at a rate of 0.4 g / g hair.

[0610] Each tress was then treated with a conventional repair shampoo (ELSEVE Total Repair 5, L'Oreal Paris) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0611] Secondly, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair and then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.) after a dwell time of 2 minutes. The hair is wrung out and then evaluated while wet. Finally, the tresses are dried with a hair dryer and then evaluated (dry).

[0612] Detangling was evaluated using a comb, while slipperiness and coating were scored based on feel. Scores ranged from 0 (lack of performance) to 5 (maximum performance).

[0613] The following results were obtained:

[0616] It should be noted that the composition according to the invention comprising an amphoteric surfactant is significantly superior in all the criteria tested compared to the composition without an amphoteric surfactant. This superiority manifests itself on wet hair by easier detangling, smoother feeling hair and more presence of its coating, signifying a better transformation of the fiber. On dry hair, the hair looks more improved (more conditioning coating) and softer (smoother feel).

[0617] Example 5

[0618] Composition H according to the invention and comparative composition H' were prepared from the following ingredients (% AM):

[0619] [Table 13]

[0620]

[0621] A composition is obtained which can be used as a rinse-out hair care product (conditioner).

[0622] Sensory evaluation

[0623] The test was carried out on tresses of medium sensitized Caucasian hair (SA20) of 2.7 g and 27 cm in length. The tresses were pre-cleaned with a standard shampoo (DOP Camomile) at a rate of 0.4 g / g hair.

[0624] Each tress was then treated with a conventional repair shampoo (ELSEVE Total Repair 5, L'Oreal Paris) at a rate of 0.4 g / g of hair. The shampoo was massaged into the tresses to form foam, then left for 15 seconds, followed by a rinsing step with water for 10 seconds (flow rate: 300 l / h, temperature: 35° C.).

[0625] Secondly, the composition to be tested is applied to wet hair at a rate of 0.4 g / g hair and then rinsed with water for 15 seconds (flow rate: 300 l / h, temperature: 35° C.) after a dwell time of 2 minutes. The hair is wrung out and then evaluated while wet. Finally, the tresses are dried with a hair dryer and then evaluated (dry).

[0626] Detangling was evaluated using a comb (1 assessor), while slipperiness and coating were scored based on feel (3 assessors). The scores ranged from 0 (lack of performance) to 5 (maximum performance).

[0627] The following results were obtained:

[0628] [Table 14]

[0629]

[0630] It should be noted that the composition according to the invention is significantly superior in all criteria tested compared to the comparative composition.

[0631] It provides greater in-use qualities (ease of detangling) and better cosmetic properties (smooth feel, coating) on ​​wet and dry hair.
