Description

Title of the invention: COMPOSITION COMPRISING A PARTICULAR SILICONE EMULSION, A POLYMER AMPHOTERIC OR CATIONIC VINYL, SURFACTANTS AND AN ACRYLIC COPOLYMER

[0001] The present invention relates to a composition for the treatment of keratinous fibers, and in particular human keratinous fibers such as hair, which comprises at least one anionic surfactant, at least one amphoteric or zwitterionic surfactant, at least one anionic (meth)acrylic associative polymer, at least one amphoteric or cationic vinyl polymer and a specific oil-in-water silicone emulsion.

[0002] The invention also relates to a process for treating keratinous fibers, preferably for washing and / or revitalizing keratinous fibers, comprising applying the composition according to the invention to the keratinous fibers.

[0003] It is common to use detergent cosmetic compositions such as shampoos and shower gels, primarily based on surfactants, to wash keratinous materials, particularly hair and skin. These compositions are applied to the keratinous materials, which are preferably wet, and the lather generated by massaging or rubbing with the hands or a washcloth, after rinsing with water, removes the various types of dirt initially present on the hair or skin.

[0004] These compositions contain significant levels of "detergent" surfactants, which, in order to formulate cosmetic compositions with good detergent power, must in particular give them good foaming power.

[0005] Surfactants useful for this purpose are generally of the anionic, non-ionic and / or amphoteric type, and in particular of the anionic type.

[0006] In parallel, in order to obtain a composition with a creamy texture, which is sought after by consumers, fatty substances such as fatty acids and fatty alcohols are commonly used in detergent compositions.

[0007] However, these fatty substances have a negative impact on the foam. The presence of fatty substances in the detergent composition significantly reduces the quantity and quality of the foam generated.

[0008] Furthermore, oil-based compositions tend to leave a surface feeling perceived by users as greasy, heavy, and insufficiently clean. They are generally not satisfactory for cleansing hair.

[0009] There is therefore a real need to offer compositions, such as com- Cosmetic and / or revitalizing positions for keratin fibers, and in particular human keratin fibers, that address the drawbacks described above, namely those that effectively remove dirt and excess sebum and enhance the cosmetic properties of said fibers, such as softness, smoothness, manageability, and detangling. These cosmetic properties can also be long-lasting.

[0010] It is interesting to propose compositions with a pleasant cream texture and capable of generating a good amount of foam, while having a low amount of non-silicone fatty substances, preferably low amounts of fatty acids and / or fatty alcohols (or even none at all).

[0011] These objectives are achieved with the present invention, one subject of which is a composition, preferably cosmetic, comprising: a. at least one anionic surfactant; b. at least one amphoteric or zwitterionic surfactant; c. at least one anionic associative polymer containing one or more motifs acrylics and / or methacrylics; d. at least one amphoteric or cationic vinyl polymer; and e. an oil-in-water emulsion having a particle size D50 less than 350 nm and comprising: f. a silicone mixture comprising (i) a trialkylpolysiloxane terminated by trialkylsilyl having a viscosity of 40,000 to less than 100,000 mPa·s at 25 °C and (ii) an amino silicone having a viscosity of 1,000 to 15,000 mPa·s at 25 °C and an amine number of 2 to 10 mg KOH per gram of amino silicone, g. a mixture of emulsifiers comprising one or more nonionic emulsifiers, wherein the mixture of emulsifiers has an HLB value of 10 to 16, and h. of water.

[0012] It has been noted that the composition according to the invention, when applied to keratinous fibers, in particular to human keratinous fibers such as hair, leads to an improvement in the condition and quality of the hair, in terms of hair feel (e.g. smooth feel, soft feel, revitalized feel, non-greasy, non-loaded) and ease of styling (e.g. combing, detangling, desirable volume, suppleness, less frizz).

[0013] In particular, it has been observed that keratinous fibers, especially hair, treated with the composition according to the invention are easier to detangle and easier to style.

[0014] In addition, the composition according to the invention has good detergent power and keratinous fibers, in particular hair, treated with the composition according to the invention are particularly clean and light.

[0015] The observed properties of the composition according to the invention are particularly durable.

[0016] In addition, it has also been observed that the composition according to the invention has a pleasant creamy texture and generates a large amount of foam.

[0017] The present invention also relates to a treatment method, in particular washing and / or revitalizing, of keratinous fibers, preferably human keratinous fibers such as hair, comprising applying the composition according to the invention to keratinous fibers.

[0207] The method for preparing the oil-in-water emulsion could further include a step of adding a biocide. The biocide could be added to protect the emulsion against microbial contamination. The amount of biocide depends on the type of biocide and the manufacturer's recommendations.

[0209] The pH of the oil-in-water emulsion after neutralization (i.e., after the addition of the biocide) is preferably 4 to 6.

[0210] The oil-in-water emulsion has a particle size D50 of less than 350 nm, preferably from 100 to 300 nm, more preferably from 150 to 250 nm, even more preferably from 150 to 225 nm, and most preferably from 160 to 200 nm. This corresponds to the mean hydrodynamic diameter of the particles. The particle size D50 is expressed in volume. The particle size D50 could be measured using a ZetaSizer instrument from Malvem, UK, model Nano-ZS, which is based on the photon correlation spectroscopy (PCS) method. - Particle size measurement

[0211] The emulsion particle size could be measured using a ZetaSizer instrument from Malvern, UK, model Nano-ZS, based on the photon correlation spectroscopy (PCS) method. The D50 value of the particle size (mean hydrodynamic diameter of the particles) is measured, the evaluation algorithm being 'cumulant analysis'.

[0212] For example, 0.5 g of the emulsion sample is placed in a 250 ml beaker, 100 ml of demineralized water is added, and the two are thoroughly mixed to obtain the sample test solution. The sample test solution is poured into the cuvette cell and placed in the slit of the instrument to measure the particle size of the emulsion. D50 is defined as the particle diameter value at 50% in the cumulative distribution. For example, if D50 = 170 nm, 50% of the particles in the sample are larger than 170 nm and 50% are smaller than 170 nm, or approximately 50% by volume of all droplets in the emulsion are 170 nm. - Viscosity measurement

[0213] Viscosity, in particular of silicones or emulsion, is measured at 25 °C and atmospheric pressure.

[0214] For viscosities between 1,000 and 40,000 mPa.s at 25 °C: the viscosity could be measured using an Anton Paar rheometer; model MCR101, single gap cylinder geometry: CC27 spindle and shear rate of 1 s for 2 minutes, at 25 °C.

[0215] For viscosities between 40,000 and 100,000 mPa.s at 25 °C: the viscosity could be measured using an Anton Paar rheometer; model MCR101, cone 25-6 (cone-plane geometry: 25 mm dia. / cone 6°); the "zero air gap" setting being made and with a shear rate of 1 s 1 for 2 minutes, at 25 °C.

[0216] Three measurements are taken for each sample and the viscosity value is taken at 60 seconds. The products in the MCR Rheometer range operate in accordance with USP (US Pharmacopeia Convention) 912 - Rotary Rheometer Methods. - Measurement of the amine index

[0217] The amine value is determined by acid-base titration using a potentiometer [Brand: Veego; Model: VPT-MG]. 0.6 g of sample is taken into a 500 mL beaker, and a 1:1 toluene-butanol mixture is added and stirred thoroughly to mix the sample; the sample solution is then titrated with 0.1 L(N) HCl solution. A blank value determination with the 1:1 toluene-butanol mixture is also performed. The amine value is calculated using the aforementioned potentiometer.

[0218] The amine index is calculated according to the formula:

[0219] 56.11 x (V - VBianc) x N / W mg KOH / g of sample,

[0220] In which

[0221] V = volume of HCl required in ml, Vbianc = volume of HCl for blank value (without sample) with the 1:1 toluene-butanol mixture in ml; N = Normality of HCl, namely 0.1 N, W = weight of the sample taken in grams. - HLB value

[0222] The term HLB is well known to those skilled in the art and designates the hydro-lipophilic ratio of a surfactant or emulsifier. In the present invention, HLB values ​​refer to values ​​at 25 °C and atmospheric pressure.

[0223] The HLB can be measured by experimental determination or can be calculated.

[0224] The calculation of the HLB value of a non-ionic surfactant is done according to the following equation: HLB = (E + P) / 5, E being the percentage by weight of the oxyethylene content and P being the percentage by weight of the polyhydric alcohol content, described in the publication Griffin, J. Soc. Cosm. Chem. 1954 (vol.5, no.4), pages 249-256.

[0225] It can also be determined experimentally according to the book by F. Puisieux and M. Seiller entitled "Galenica 5: Dispersed systems - Volume I - surfactants and emulsions - Chapter IV - Notions of HLB and critical HLB, pages 153-194 - paragraph 1.1.2. Determination of HLB by experimental means, pages 164-180".

[0226] The calculated HLB is the preferred HLB values ​​that should be taken into account.

[0227] This calculated HLB could be defined as follows:

[0228] “HLB calculated = 20 x molar mass of the hydrophilic part / total molar mass”.

[0229] For an oxyethylenated fatty alcohol, the hydrophilic part corresponds to the oxyethylene motifs condensed on the fatty alcohol and the "calculated HLB" then corresponds to the "Griffin HLB" as defined above.

[0230] For an ester or an amide, the hydrophilic part is naturally defined as being located beyond the carbonyl group, starting with the fatty chain(s).

[0231] For ionic surfactants / emulsifiers, the HLB value of each surfactant / emulsifier can be calculated by applying Davies' formula as described in Davies JT (1957), "A quantitative kinetic theory of emulsion type, I. Physical chemistry of the emulsifying agent", Gas / Liquid and Liquid / Liquid Interface (Proceedings of the International Congress on Surface Activity): 426-438.

[0232] According to the formula, the HLB is derived by summing the hydrophilic / hydrophobic contribution offered by the structural components of the emulsifier:

[0233] HLB = (number of hydrophilic groups) - n(number of groups per CH2 group) + 7.

[0234] Approximate values ​​of HLB for certain cationic emulsifiers are data in Table IV, in "Cationic emulsifiers in cosmetics", GODFREY, J. Soc. Cosmetic Chemists (1966) 17, pages 17-27.

[0235] When two emulsifiers A and B of known HLB are mixed for use, the HLB mixture is said to be the HLB required for the mixture. This is expressed by the equation (WAHLBA + WbHLBb) / (Wa + WB) = HLB mixture, where WA = the amount (weight) of the first emulsifier (A) used and WB = the amount (weight) of the second emulsifier (B); HLBa, HLBb = the HLB values ​​assigned to emulsifiers A and B; HLB mixture = the HLB of the mixture.

[0236] Said oil-in-water emulsion is described for example in document WO 2017 / 108824.

Then, 31 g of trideceth-3 and 350 g of trideceth-10 (80% active material) were added. This mixture of nonionic emulsifiers had an HLB value of 11.25.

[0306] 80 g of water and 6.2 g of glacial acetic acid were then added to the reservoir and the Mixing began. Mixing continued until the entire mass became a creamy paste. The entire paste was transferred to the emulsion tank. Homogenization was carried out for 30 minutes at room temperature. 79.6 g of demineralized water were added and homogenization was carried out for 60 minutes. 72.7 g of demineralized water were added and homogenization was carried out for 50 minutes. 197.4 g of demineralized water were added and homogenization was carried out for 5 minutes. 294.3 g of demineralized water were added and homogenization was carried out for 5 minutes. 180 g of demineralized water were added and homogenization was carried out for 5 minutes. 180 g of demineralized water were added and homogenization was carried out for 5 minutes. 197.4 g of demineralized water were added and homogenization was carried out for 5 minutes.197.4 g of demineralized water were added and homogenized for 3 minutes. 228.5 g of demineralized water were added and homogenized for 3 minutes.

[0310] Protocol:

[0311] The hair strands were shampooed, rinsed with water and placed on a heating plate (30 °C). Then, 1.2 g of the test composition were applied to 3 independent hair strands (3 g, 20 cm, medium bleached hair).

[0312] Next, fingers were passed through the strand five times for five seconds. Each strand was passed between two fingers to remove excess water (1 pass).

[0326] Each lock of hair was then wrapped around the fingers, or each lock was placed in a watch glass. Compositions A and B were applied to each strand of hair (uniformly from roots to tips). The strands were gently massaged by passing each strand approximately six times between two fingers for fifteen seconds, from roots to tips (without creating knots), in order to lather the compositions. The strands were then rinsed with tap water and fingers were run through the hair fifteen times for ten seconds. Each strand was finally passed between two fingers to remove excess water (2 passes). Each wet strand of hair was placed on a combing machine (Diastron MTT 175 from Dia-Stron Limited UK) and a comb with a sensor was placed in the hair fibers. The combing was carried out by sweeping the strand of hair from root to tip and measuring the friction force. Measurements were taken 5 times per hair strand. In total, measurements were taken 15 times per test composition. The maximum force was selected from the measured data of each strand of hair. The average value of the 5 maximum forces was calculated in gram-force (gf): 1 gf corresponds to approximately 0.0098 Newtons. The weaker the force, the easier the keratin fibers are to comb / detangle. The same protocol was repeated with the same strands, once completely dry. Test conditions: 23°C, 54% humidity Combing speed = 1500 mm / minute The results are shown in Tables 2 (dry combing) and 3 (wet combing) below.

[0335] [Table 3] Wet combing Compositions Average value of the 5 maximum strengths (in gf) A (Invention) 90.33 B (Comparative) 114.75 It is observed that composition A according to the invention offers a smoother feel, better combing and better detangling of the hair than the comparative composition B. The results are significant due to the T test (p value < 0.05). Furthermore, composition A according to the invention has a pleasant creamy texture, while the comparative composition B has an excessively liquid texture. The viscosities of the inventive and comparative compositions are measured at 25 °C using a Lamy rheological viscometer. The samples are placed in the viscosity cup, and appropriate pins are used. The pins are selected in ascending order of viscosity. For example, pins M1 and M2 are used for liquid to semi-liquid formulations, while pins M3 and M4 are used for semi-thick to thick formulations. The viscosity is measured at 30 s. The details of the viscosity results are as follows: [Table 4] Viscosity results: Composition Spindle No. Time (s) Speed ​​(rpm) Viscosity (mPa.s) A (Invention) M4 30 200 6 430 mPa.s B (Comparative) M3 30 200 3 600 mPa.s Composition A according to the invention has a higher viscosity than the comparative composition B.
