Description

A COSMETIC PROCESS OF ALTERING KERATIN FIBERSFIELD OF INVENTION

[0001] The present disclosure relates to the field of cosmetics, in particular relates to a cosmetic process, and more particularly, to a cosmetic process of altering keratin fibers, in particular hair.BACKGROUND OF INVENTION

[0002] Hair is indeed highly prone to dryness, damage, and can become fragile and weakened due to external influences. Damaged hair can result from excessive heat styling, chemical treatments, sun exposure, and poor hair care habits. Damaged hair loses its quality, resulting in tangling, styling difficulties, and a lack of softness. To treat these problems, it is common to use moisturizing shampoos, conditioners, deep conditioning treatments, heat protectants, hair masks, oil treatments, and regular trimming. Said methods can help in hair repair and prevention of further damage.

[0003] Hence, to enhance the conditioning and overall feel of hair, the use of hair care products that can deeply moisturize, reduce friction, improve hair texture, and provide a luxurious and silky finish is increasing day by day. However, many formulations available on the market may not impart the desired benefits, particularly in terms of achieving smoothness and softness, compatible with both dry and wet conditions. Therefore, consumers are still looking for products that can provide completely satisfactory and long-lasting cosmetic benefits, especially for hair that is extremely brittle, sensitized, or damaged. Consumers are also becoming more conscious of selecting products that are safe and aesthetically appealing. This trend is especially evident among hair dye users, who are increasingly opting for environmentally friendly, sustainable products.

[0004] As a result, the prevailing trend is moving towards more eco-friendly formulations for dyeing and / or lightening keratin strands. These products frequently use natural ingredients that are kinder to the hair, preserving its healthand integrity while achieving the desired color or lightening effects. These hair dye products minimize petrochemical content and provide environmental advantages.

[0005] Therefore, consumers are looking for processes that offer a comprehensive solution, providing alteration of the hair. This includes coloring, lightening, improved conditioning, and easier detangling and combing, under both wet and dry hair conditions, all with long-lasting effects.

[0006] Thus, there is a need for a cosmetic process of altering keratin fibers which can provide sustainable hair coloring, dry and wet detangling, while preserving the hair’s suppleness and silky finish.SUMMARY OF THE INVENTION

[0365] The oil-in-water emulsion may also comprise a preservative, such as phenoxyethanol, in an amount ranging from 0.5 to 1% by weight relative to total weight of the emulsion

[0366] A process for preparing the oil-in-water emulsion preferably comprises: - a step of mixing one or more polydialkylsiloxanes containing trialkylsilyl end groups, having a viscosity, at 25°C, ranging from 40000 to 100000 mPa.s, and one or more amino silicones having a viscosity, at 25°C, ranging from 1000 to 15000 mPa.s and an amine number ranging from 2 to 10 mg of KOH per gram of amino silicone; at a temperature of from 15°C to 40°C, in particular at 25°C, in order to obtain a fluid mixture of silicones; then-a step of adding a surfactant mixture comprising one or more non-ionic surfactants, said mixture having an HLB ranging from 10 to 16, to said fluid mixture of silicones, in order to obtain an emulsified silicone mixture; then-a step of homogenizing said emulsified silicone mixture, followed by-a step of adding water, especially demineralized water, preferentially in steps, in order to obtain an oil-in-water emulsion having a particle size D50 of less than 350 nm.

[0367] The preparation process may also comprise an additional step of adding one or more preservatives.

[0368] The pH of the oil-in-water emulsion is generally between 4 and 6.

[0369] The oil-in-water emulsion has a particle size D50 of less than 350 nm, especially of between 100 and 300 nm, better still between 150 and 250 nm, or even between 160 and 200 nm.

[0370] This size corresponds to the average hydrodynamic particle diameter. The particle size D50 is expressed by volume. It can be measured using a ZetaSizer device from Malvern, UK, model Nano-ZS, based on the “Photon Correlation Spectroscopy (PCS)” method.Method for measuring the particle size

[0371] The particle size of the emulsion is measured using a ZetaSizer device fromMalvern, UK, model Nano-ZS, based on the “Photon Correlation Spectroscopy (PCS)” method.

[0372] The particle size D50 is measured when the evaluation algorithm is “cumulant analysis”.

[0373] 0.5 g of the emulsion is placed in a 250 ml beaker, 100 ml of demineralized water is added, and mixing is carried out in order to obtain the solution to be tested. The solution to be tested is placed in the measuring vessel (or cell) and introduced into the measuring device.

[0374] The size D50 corresponds to the particle diameter value at 50% in cumulative distribution.

[0375] For example, if Dso=17O nm, this means that 50% of the particles have a size of greater than 170 nm, and that 50% of the particles have a size of less than 170 nm.

[0376] It should be recalled that this distribution is by volume.Method for measuring the viscosity

[0377] The viscosities, especially of the silicone compounds, are measured at 25°C, 1 atm.

[0378] To measure viscosities of between 1000 and 40000 mPa at 25°C, use may be made of an Anton Paar rheometer, model MCR101, cylinder geometry, single gap: CC27 spindle, shear rate 1 s’1for 2 minutes, at 25°C.

[0379] To measure viscosities of between 40000 and 100000 rnPa.s at 25°C, use may be made of an Anton Paar rheometer, model MCR101, 25-6 cone (cone-plate geometry, 25 mm in diameter / 60cone); Zero gap, shear rate 1 s1for 2 minutes, at 25°C.

[0380] Three measurements are carried out for each sample, and the viscosity value is taken at 60 seconds. The MCR Rheometer Series products operate according to the USP convention (US Pharmacopeia Convention, 912 - Rotational Rheometer methods).Method for measuring the amine number

[0381] The amine number can be measured by acid-base titration, using a potentiometer [Make: Veego; model VPT-MG].

[0382] 0.6 g of the sample is placed in a 500 ml beaker and a 1:1 toluene-butanol mixture is added, then mixing is carried out.

[0383] The solution is titrated with a 0.1 N HC1 solution. A determination of the zero value (Vbiank) is also carried out with the 1:1 toluene-butanol mixture alone.

[0384] The amine number is calculated by means of the formula:

[0385] 56.11 x (V - V Blank) x N / W mg KOH / g of sample

[0386] with V= volume of HC1 required (in ml), > volume of HC1 requiredfor the zero value (in ml); N= normality of HC1, i.e. 0.1, and W= weight of the sample (in g).HLB values

[0387] The term HLB relates to the hydrophilic-lipophilic balance of a surfactant. It can be measured experimentally or calculated.

[0388] In the present application, the HLB values are the values at 25°C.

[0389] The HLB values can be calculated by means of the following equation: HLB = (E + P) / 5, in which E is the % by weight of oxy ethylene and P is the % by weight of polyol, as is described in the publication Griffin, J. Soc. Cosm. Chem. 1954 (vol.5, No. 4), pages 249-256.

[0390] The HLB values can also be determined experimentally according to the book by Puisieux and Seiller, entitled “Galenica 5: Les systemes disperses [Galenica 5: Dispersed systems] - Volume I - Agents de surface et emulsions [Surface agents and emulsions] - Chapter IV - Notions de HLB et de HLB critique [Notions of HLB and of critical HLB], pages 153-194 - paragraph 1.1.2. Determination de HLB par voie experimentale [Experimental determination of HLB], pages 164-180”.

[0391] Preferably, the HLB values that will be taken into account are those obtained by calculation, especially in the following way: “calculated HLB” = 20 * (molar mass of the hydrophilic part / total molar mass).

[0392] Thus, for an oxyethylenated fatty alcohol, the hydrophilic part corresponds to the oxyethylene units fused to the fatty alcohol and the “calculated HLB” then corresponds to the “HLB according to Griffin”.

[0393] For an ester or an amide, the hydrophilic part is generally defined as beingbeyond the carbonyl group, starting from the fatty chain(s).

[0394] The HLB values of non-ionic surfactants can also be calculated by means of the 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 of Surface Activity): 426-438.

[0395] According to this formula, the HLB value is obtained by adding the hydrophilic / hydrophobic contribution linked to the constituent groups in the surfactant:HLB = (number of hydrophilic groups) - n(number of groups per CH2 group) +7.

[0396] The HLB values of some cationic surfactants are given in Table IV, in "Cationic emulsifiers in cosmetics", GODFREY, J. Soc. Cosmetic Chemists (1966) 17, pages 17-27.

[0397] When two surfactants A and B, of known HLB values, are mixed, the HLB Mix corresponds to the HLB of the mixture and can be expressed by the following equation:HLBMI = (WAHLBA + WBHLBB) / (WA + WB)in which WA is the amount (weight) of the 1stsurfactant A and WB the amount of the 2ndsurfactant B, and HLBA and HLBB are the HLB values of the surfactant A and of the surfactant B.

[0439] For the purposes of the present invention, the term "sugar unit" means an oxygen-bearing hydrocarbon-based compound containing several alcohol functions, with or without aldehyde or ketone functions, and which includes at least 4 carbon atoms.

[0440] The sugar units may be optionally modified by substitution, and / or by oxidation and / or by dehydration.

[0441] The sugar units of the nonionic polysaccharides are preferably derived from the following sugars: glucose; galactose; arabinose; rhamnose; mannose; xylose; fucose; anhydrogalactose; and fructose.

[0450] Thus, the cellulose-based polymers that may be used according to the invention may be chosen from unsubstituted celluloses, including those in a microcrystalline form, and cellulose ethers.

[0451] Among these cellulose-based polymers, cellulose ethers, cellulose esters and cellulose ether esters are distinguished.

[0569] Similarly, second composition C2 (according to the present invention) was prepared by mixing components mentioned in Table 2 with quantity sufficient of water.Table 1Table 2Example 2Evaluation of colour strength and colour uptake

[0570] Protocol: The first composition, Cl (according to the invention), was mixed with an oxidizing composition comprising 6% hydrogen peroxide in a weight ratio of 1:1. The obtained mixture was applied to locks of hair containing 90% natural grey hair, in a proportion of 2 g of mixture per 1 g of hair. After a leave-on time of 30 minutes on a hot plate at 27°C, the hair was rinsed and washed. Then, 0.4 g of the second composition, C2 (according to the invention), was applied to the dyedhair. After a leave-on time of 20 minutes on a hot plate at 27 °C, the hair was again rinsed, washed, and dried. Color readings were taken after applying the first composition Cl and after applying the second composition C2.

[0571] Procedure: The colouring of the hair was evaluated in the L*a*b* system, using a Konica 2600D instrument. The CIELAB 1976 system was used, and the color of the hair was detected via three main coordinates, L*, a* and b*.

[0572] In this system, L* represents clarity and gave the position on a vertical axis ranging from 0 (black) to 100 (white). The lower the value of L*, the darker and more powerful (intense) the colouring obtained. The chromaticity was measured by the values a* and b*, a* representing the red / green component and b* the yellow / blue component. The extent of hair colouring at both stages and corresponding L* values obtained are tabulated in Table 3 below.

[0573] Results: The results confirmed that the application of the first composition, Cl (according to the invention), followed by the application of the second composition, C2 (according to the invention), resulted in intense coloring effect compared to the application of the mixture of the first composition with the oxidizing composition only.Table 3

[0574] Accordingly, it was observed that the cosmetic process of altering keratin fibers by applying a first composition and a second composition on the keratin fibers, as disclosed in various embodiments herein, facilitated enhanced hair colouring. This process provided a more intense colour after the application of first composition, Cl and second composition, C2 compared to the application of the first composition Cl alone.ADVANTAGES OF THE PRESENT DISCLOSURE
