Description

Title of the invention: Composition comprising Drometrizole Trisiloxane, a hydrophilic organic filter, with a mass ratio of hydrophilic organic filters / lipophilic organic filters greater than 0.3, without alcohol

[0001] The present invention relates to a composition, and in particular a cosmetic or dermatological composition, comprising Drometrizole Trisiloxane and at least one hydrophilic organic UV filter, the mass ratio between the hydrophilic organic UV filters and the lipophilic organic UV filters being greater than 0.3, and the amount of ethanol being less than or equal to 3% by weight relative to the total weight of the composition. Technical field

[0002] To date, a wide variety of photoprotective compositions are already known for protecting keratin materials, and more particularly the skin, against the harmful effects induced by UVA and / or UVB radiation. Essentially, they contain a combination of several organic or inorganic UV filters, carried in an oily phase and / or in an aqueous phase, as an anti-UV active agent and are generally provided in a galenic form of the emulsion or gel type.

[0003] It is also known that high filter rates are necessary to achieve high levels of filtering efficiency.

[0004] However, high levels of UV filters do not lend themselves to easy development of compositions with a stabilized and pleasant texture.

[0005] Thus, formulations with high filtering power can have uncomfortable or even unpleasant sensory aspects masking the freshness and comfort of the formulas. In particular, the difficulty for photoprotective formulations with a high protection index is often to limit, or even avoid, a significant feeling of greasyness and stickiness, and therefore a lack of lightness of the textures obtained, but also a white appearance on application and therefore not invisible on the skin.

[0006] In addition, sensory discomforts such as "linting" phenomena are sometimes observed with cosmetic compositions, namely the formation of fluff during application of the product and / or after drying and / or penetration of the product into the skin. This phenomenon appears in particular when the sunscreen composition contains a high level of hydrophilic filters.

[0007] This defect is prohibitive for the user, because the application is not homogeneous or pleasant given this fluffy effect when applying or during removal of the product. In addition, it gives a “dirty” impression on the skin. This can greatly affect the photoprotective properties of sunscreen compositions.

[0008] To overcome the aforementioned undesirable effects, and in particular to obtain a fresh effect on application and an invisible effect on the skin, aqueous galenics have already been considered. However, these aqueous compositions containing UV filters can have the disadvantage of being sticky and therefore uncomfortable, but also very fluid.

[0009] It has also been proposed to structure an aqueous gel containing filters by polymers. This solution is however not satisfactory because the structuring polymers generally chosen are not always very resistant to electrolytes and can also degrade the sensory properties of the compositions in terms of stickiness.

[0010] To overcome the aforementioned undesirable effects, the use of aqueous compositions containing UV filters in association with other specific compounds has already been considered.

[0011] Thus, the joint use of clay-type mineral thickeners has been proposed to stabilize the compositions and possibly reduce the stickiness of the photoprotective compositions. However, the clays can whiten the compositions, which then lose their transparency properties.

[0012] Consequently, it remains difficult to reconcile, in the same photoprotective composition, opposing technical performances, such as a high level of UV protection which most often involves a greasy and sticky finish on the skin, and a pleasant sensory experience materialized in particular by a sensation of freshness, and an absence of the phenomenon of fluffing.

[0013] There still remains a need for a photoprotective composition with a high level of UV protection and which is advantageously transparent on the skin.

[0014] In particular, there remains a need for a photoprotective composition with a high level of UV protection, with pleasant sensory properties, which does not fluff during and after application, and which is advantageously refreshing, and preferably transparent on the skin.

[0015] This need for such a photoprotective composition is all the stronger as the market for daily photoprotection is expanding. More and more hybrid products providing skin care and protection with SPF 15-20 are being launched, but the challenge remains of having higher SPF values, for example greater than or equal to 30, or even greater than or equal to 50, with a pleasant sensoriality for daily application.

[0016] We therefore seek to have a product with high SPF while keeping the sensory codes of skin care: Appearance, texture, consistency, sensory.

[0017] In particular, the aim of the invention is to develop a product allowing good homogeneity of the composition and good quality of deposition of the composition on the skin in order to obtain in particular an interesting sensory effect such as a reduction, or even an absence, of the appearance of fluff during and after application, while allowing high daily photoprotection.

[0018] There also remains a need for a photoprotective composition with a high level of UV protection and which is perfectly stable, i.e. not subject to demixing phenomena.

[0019] The present invention aims precisely to meet these needs. Statement of the invention

[0020] The present invention therefore relates to a composition, and in particular a cosmetic or dermatological composition, comprising: a) Drometrizole Trisiloxane; and b) at least one hydrophilic organic UV filter; the mass ratio between hydrophilic organic UV filters and lipophilic organic UV filters being greater than 0.3; the quantity of ethanol being less than or equal to 3% by weight relative to the total weight of the composition.

[0021] Against all expectations, the inventors have found that the use, in a photoprotective composition, of Drometrizole Trisiloxane in association with one or more hydrophilic organic UV filters, the mass ratio between the hydrophilic organic UV filters and the lipophilic organic UV filters being greater than 0.3, and the quantity of ethanol being less than or equal to 3% by weight relative to the total weight of the composition, makes it possible to obtain a galenic formulation having a high photoprotective power, with good cosmetic properties, in particular which does not fluff during and after application and with a non-greasy, non-sticky and non-shiny finish, and which is nevertheless stabilized over time.

[0022] Advantageously, the implementation of this composition makes it possible to access a galenic formulation which is stabilized, presenting a pleasant sensoriality for daily use and a strong anti-UV protective power.

[0023] Thus, this photoprotective composition advantageously makes it possible to combine properties which are generally antagonistic to each other.

[0024] The invention also relates, according to another of its aspects, to the use of a composition as defined above, for the care of keratin materials, in particular the skin of the body and / or the face.

[0025] The invention also relates, according to yet another of its aspects, to a non-therapeutic cosmetic process for making up and / or caring for keratin materials, in particular of the skin of the body and / or face, comprising at least the application to said keratin materials of a composition as defined above.

[0026] It also relates to a non-therapeutic cosmetic process for limiting the darkening of the skin and / or improving the color and / or uniformity of the complexion comprising the application to the surface of the keratin material of at least one composition as defined above.

[0027] It also relates to a non-therapeutic cosmetic process for preventing and / or treating the signs of aging of a keratin material comprising the application to the surface of the keratin material of at least one composition as defined above.

[0028] The composition in accordance with the invention has good stability. This stability can be evaluated macroscopically and / or microscopically, after storage for one week, one month, or two months, at room temperature (25°C), at 4°C, at 45°C, or at 55°C. A stable composition generally retains its pleasantness and its sensory signature upon application over time. More precisely, the stability of a composition can be evaluated qualitatively, for example by the absence of phase shift phenomena or the appearance of crystals, or quantitatively by monitoring the evolution of parameters such as viscosity or pH.

[0029] For the purposes of the present invention, “linting” consists of the appearance of solid and persistent particles on the surface of the skin during spreading. These particles are visible and felt under the fingers.

[0030] In the context of the invention, the filtering efficiency is evaluated from the evaluation of the SPF and the UVAPF.

[0031] For the purposes of the present invention, the term "SPF" (Sun Protection Factor) means: the sun protection factor, which measures the level of protection against UVB rays. The SPF value corresponds to the ratio between the minimum time required to obtain sunburn with an antisun composition and that without the product. More specifically, the term "SPF" is defined in the article A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum, J. Soc. Cosmet. Chem., 40, 127-133 (May / June 1989).

[0032] The SPF (Sun Protection Factor) assessment can be carried out in vitro using the Labsphere® spectrophotometer. The plate is the material on which the sunscreen composition is applied. For this protocol, polymethylmethacrylate (PMMA) plates have proven ideal. A particular protocol, presented as an example, is currently undergoing ISO approval under the name ISO Committee Draft 23675.

[0033] The evaluation of the Sun Protection Factor (SPF) of the compositions can also be carried out in-vivo according to the ISO / EN 24444: 2019 protocol “ Cosmetics-Sun protection test methods-In-vivo determination of the sun protection factor (SPF)”.

[0034] For the purposes of the present invention, UVAPF means the index characterizing protection against UVA. In particular, this index can be measured in vivo according to the “PPD” (Persistent Pigment Darkening) method, ISO-24442:2022 protocol, and measures the skin color observed 2 to 4 hours after exposure to UVA. The evaluation of protection against UVA can also be measured in vitro using the Labsphere® spectrophotometer. The plate is the material on which the sunscreen composition is applied. For this protocol, polymethylmethacrylate (PMMA) plates have proven ideal. The ISO 24443:2021 protocol describes such an in vitro method.

[0035] Other characteristics, aspects and advantages of the invention will appear on reading the detailed description which follows.

[0036] The composition according to the invention is intended for topical application and therefore contains a physiologically acceptable medium. Here, the term “physiologically acceptable medium” means a medium compatible with keratin materials.

[0037] In the context of the present invention, the term "keratin material" is understood to mean in particular the skin, the scalp, the keratin fibers such as the eyelashes, the eyebrows, the hair, and the body hairs, the nails, the mucous membranes such as the lips, and more particularly the skin and the mucous membranes (body, face, eye contour, eyelids, lips, preferably body, face and lips).

[0038] In what follows, and unless otherwise indicated, the limits of a domain of values ​​are included in this domain, in particular in the expressions “between” and “ranging from ... to ...”.

[0039] Furthermore, the expressions “at least one” and “at least” used in the present description are respectively equivalent to the expressions “one or more” and “greater than or equal”.

[0040] By "prevent" or "prevention", according to the invention, is meant the fact of reducing the risk of occurrence or slowing down the occurrence of a given phenomenon, namely, according to the present invention, the signs of aging of a keratin material.

[0041] By "organic UVA filter" is meant any organic chemical molecule capable of absorbing at least UVA radiation in the wavelength range between 320 and 400 nm; said molecule can also additionally absorb UVB radiation in the wavelength range between 280 and 320 nm.

[0042] By “organic UVB filter” is meant any organic chemical molecule capable of exclusively absorbing UVB radiation in the wavelength range between 280 and 320 nm.

[0043] According to a particular embodiment of the invention, the composition is in the form of an emulsion.

[0044] By "emulsion" is meant any macroscopically homogeneous, kinetically stable composition comprising at least two phases which are immiscible with each other; one being the continuous dispersing phase and the other being dispersed in said continuous phase in the form of droplets. The two phases are generally kinetically stabilized by at least one emulsifying system generally comprising at least one emulsifying surfactant.

[0045] A distinction is made between so-called "direct" oil-in-water emulsions consisting of a continuous aqueous dispersing phase and a discontinuous oily dispersed phase and water-in-oil emulsions called inverse emulsions consisting of a continuous oily dispersing phase and a discontinuous aqueous dispersed phase. There are also multiple emulsions such as water-in-oil-in-water or oil-in-water-in-oil emulsions. Detailed description of the invention UV filters

[0161] According to a particular embodiment of the invention, the composition comprises at least one filler chosen from spherical particles of porous silica, spherical particles of cellulose, and N-acylated amino acid powders.

[0162] By filler, we mean particles of any shape, colorless or white, mineral or synthetic, insoluble in the medium of the composition whatever the temperature at which the composition is manufactured.

[0163] The fillers used in the present invention can be characterized by their specific surface area per unit mass or per unit volume, their size expressed as volume average diameter D(4.3), their unpacked density, and / or their oil absorption capacity.

[0164] The specific surface area per unit mass can be determined by the nitrogen absorption method called BET method (BRUNAUER - EMMET - TELLER) described in "The journal of the American Chemical Society", vol. 60, page 309, February 1938 and corresponding to the international standard ISO 5794 / 1 (annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles considered.

[0165] The specific surface area per unit volume is given by the relation: Sv = SM xp where p is the packed density expressed in g / cm3 and SM is the specific surface area per unit mass expressed in m2 / g, as defined above.

[0166] In the context of the present invention, this density can be assessed according to the following protocol, known as the packed density: 40 g of powder are poured into a graduated cylinder; then the cylinder is placed on the ST AV 2003 device from STAMPF VOLUMETER; the cylinder is then subjected to a series of 2500 tampings (this operation is repeated until the difference in volume between 2 consecutive tests is less than 2%); then the final volume Vf of tamped powder is measured directly on the cylinder. The density packed is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm3 and m in g).

[0167] The oil absorption capacity measured at the Wet Point, and noted Wp, corresponds to the quantity of oil that must be added to 100 g of particles to obtain a homogeneous paste.

[0168] It is measured according to the so-called Wet Point method or method for determining powder oil uptake described in standard NF T 30-022. It corresponds to the quantity of oil adsorbed on the available surface of the powder and / or absorbed by the powder by measuring the Wet Point, described below.

[0169] A quantity m= 2 g of powder is placed on a glass plate and then the oil (isononyl isononanoate) is added drop by drop. After adding 4 to 5 drops of oil to the powder, it is mixed with a spatula and the oil is continued to be added until conglomerates of oil and powder form. From this point on, the oil is added one drop at a time and the mixture is then kneaded with the spatula. The addition of oil is stopped when a firm and smooth paste is obtained. This paste should be spread on the glass plate without cracking or lumps forming. The volume Vs (expressed in ml) of oil used is then noted.

[0170] The oil intake corresponds to the ratio Vs / m.

[0171] The sizes of the charges can be measured by static light scattering using a commercial granulometer of the MasterSizer 2000 type from Malvem. The data are processed on the basis of the Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" particle diameter. This theory is notably described in the work of Van de Hulst, HC, "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0172] According to a particular embodiment, the fillers which can be used in the present invention have an oil absorption capacity of 0.25 g / g to 3.5 g / g, preferably of 0.93 g / g to 2.5 g / g, or even of 1.25 g / g to 2.5 g / g.

[0227] It is also possible, by HHP (between 50 and 800 bars), to obtain stable dispersions with drop sizes that can go down to 100 nm.

[0228] The emulsions may generally contain at least one emulsifier chosen from amphoteric, anionic, cationic or non-ionic emulsifiers, used alone or as a mixture. The emulsifiers are chosen appropriately depending on the emulsion to be obtained (W / O or O / W).

EXAMPLES

[0241] The present invention will now be described more specifically by way of examples, which are in no way limiting of the scope of the invention. However, the examples make it possible to support specific characteristics, variations, and preferred embodiments of the invention.

[0242] In these examples, the quantities of the ingredients present in the compositions are given in % by weight of raw materials relative to the total weight of the composition. Method of preparation of the exemplified compositions

[0243] Phase A is prepared as follows: Introduction of raw materials of phases A1 and A2 into a beaker and heating to 65°C with magnetic stirring. Dispersion until a clear mixture is obtained. Introduction of raw materials of phase A3. Dispersion until a clear mixture is obtained while maintaining the temperature at 65°C. Phase B is prepared as follows: Introduction of the raw materials of phase B1 into a beaker and heating to 75°C while stirring with scraper blades. Dispersion until a clear mixture is obtained. Stop heating and add the raw materials of phase B2 and then phase B3 while stirring. Dispersion until a homogeneous mixture is obtained and the temperature is maintained at 65°C. At 65°C, phase A is slowly poured into phase B, with rotor-stator stirring and scraping blades. Dispersion until a suitable emulsion is obtained. Dilution by introducing phase C with stirring. Dispersion under rotor-stator agitation and scraping blades until a homogeneous mixture is obtained while starting cooling. Continued cooling under scraping blades alone. At a temperature < 30°C, add phase D and the raw materials of phase E. Dispersion with rotor-stator stirring and scraper blades until a homogeneous mixture is obtained while continuing to cool. Continue cooling under scraper blades alone if necessary. Introduction of phase F and G. Dispersion under scraping blades only until a homogeneous mixture is obtained while maintaining the temperature. Confocal microscopy studies

[0244] The microscopic study of the compositions is carried out using a Leica SP8 confocal microscope.

[0245] The advantage of the confocal mode is a very fine definition of the observed focal plane, thanks to the presence of a diaphragm at the detector level. We thus observe only the photons coming from the focal plane. Displacements can be performed in the three dimensions of X, Y, and Z space. X and Y represent the lateral displacements of the sample, and Z represents the thickness of the sample. The observation of the sample is done using a x63 objective with oil to allow optical contact.

[0246] Two studies were carried out by confocal fluorescence microscope. The first study consists of observing the homogeneity of the emulsion (in bulk) while the second study allows observing the homogeneity of the deposit (spreading and drying of the composition on a glass slide).

[0247] In order to label the samples, 5 pL of a 102 mol.L 1 fluorophore solution are added to approximately 2 g of each of the compositions studied. The labeling step is carried out 24 hours before observation in order to allow good diffusion of the fluorophores. Two markers (fluorophores) are used for this study, fluorescein for the aqueous phase, and Nile Red for the fatty phase.

[0248] Confocal fluorescence microscopy allows the selective observation of each phase of an emulsion by soliciting the fluorophores at their respective excitation wavelength. For the aqueous phase, the laser excites the Fluorescein molecule in the blue (458 nm), which re-emits in the green (500-550 nm). For the oil phase, the laser excites the Nile Red molecule in the yellow (561 nm), which re-emits in the red (600-680 nm).

[0249] To observe the bulk emulsion, a drop of the sample is placed on a glass slide. To observe the deposit, the sample is spread on a glass slide with a bar coater (automatic spreader) set at 25 pm. It is then placed under a hood to let it dry for 1 hour at room temperature. Sensory evaluation protocol for fluffiness

[0250] The compositions were sensorially tested blindly and monadically on a panel composed of 64 Chinese women per cell, aged 18 to 35, with all skin types (oily, normal and dry), regular consumers of cosmetic skin care compositions with a high SPF index, 50% being regular consumers of pharmaceutical products, including one of the top sellers UV Daily with SPF present on the Chinese market, and 50% being regular consumers of various photoprotection products (not necessarily pharmaceutical). To carry out this sensory evaluation, each volunteer applied the composition to be tested on the skin of their face at least once a day over a test period of 3 days. The test was carried out in China, under temperature conditions between 21°C and 35°C, with an air humidity level between 80% and 90%. Comparative example 1 - Compositions 1 to 4
