Description

Title of the invention: Composition comprising a lipophilic organic filter, a hydrophilic organic filter, spherical porous silica particles, spherical cellulose particles, and an N-acylated amino acid powder

[0001] The present invention relates to a composition, and in particular a cosmetic or dermatological composition, comprising at least one lipophilic organic UV filter, at least one hydrophilic organic UV filter, and at least three distinct fillers, the first of which is selected from porous silica spherical particles, in particular porous silica microparticles, the second from cellulose spherical particles, and the third from N-acylated amino acid powders. The total quantity of fillers selected from porous silica spherical particles, cellulose spherical particles, and N-acylated amino acid powders is between 1% and 4% by weight, preferably between 2% and 4% by weight of the total weight of the composition, and the mass ratio (cellulose spherical particles + N-acylated amino acid powders) / (porous silica spherical particles) is between 0,25 and 1. , technical field

[0002] To date, a wide variety of photoprotective compositions are already known to protect keratinous materials, and more specifically 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, delivered in an oily and / or aqueous phase, as an active anti-UV agent, and are generally offered in an emulsion or gel formulation.

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

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

[0005] Thus, formulations with high filtering power can present uncomfortable or even unpleasant sensory aspects that mask the freshness and comfort of the formulas. In particular, the difficulty for high-SPF photoprotective formulations is often to limit, or even avoid, a significant feeling of greasiness and stickiness, and therefore a lack of lightness in the resulting textures, as well as a white appearance upon application, making it invisible on the skin.

[0006] Furthermore, the introduction of high-concentration UV filters can cause destabilization problems. This instability can even sometimes cause a phase shift of emulsification and / or loss of viscosity of the composition, rendering the formulation ineffective or even unusable.

[0007] To overcome the aforementioned undesirable effects, and in particular to obtain a cooling effect upon application and an invisible effect on the skin, aqueous formulations 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.

[0008] It has also been proposed to structure an aqueous gel containing filters using polymers. However, this solution is not satisfactory because the structuring polymers generally used are not always very resistant to electrolytes and can also degrade the sensory properties of the compositions in terms of stickiness.

[0009] To overcome the aforementioned undesirable effects, the implementation of aqueous compositions containing UV filters in association with other specific compounds has already been considered.

[0010] Thus, the combined use of clay-type mineral thickeners has been proposed to stabilize the compositions and possibly reduce the stickiness of the photoprotective compositions. However, clays can bleach the compositions, which then lose their transparency properties.

[0011] 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 implies a greasy and sticky finish on the skin, and a pleasant sensory experience materialized in particular by a sensation of freshness.

[0012] There is still a need for a photoprotective composition with a high level of UV protection and which is advantageously transparent on the skin.

[0013] In particular, there remains a need for a photoprotective composition with a high level of UV protection, with pleasant sensory properties and which is advantageously refreshing for health, and preferably transparent on the skin.

[0014] This need for such a photoprotective composition is all the more pressing given the rapid expansion of the daily photoprotection market. More and more hybrid products providing skincare and SPF 15-20 protection are being launched, but the challenge remains to achieve higher SPF values, for example, 30 or higher, or even 50 or higher, with a pleasant sensory experience for daily application.

[0015] We therefore seek to have a product with high SPF while retaining the sensory codes of skin care: Appearance, texture, consistency, sensory.

[0016] In other words, the aim of the invention is to develop a product with an appealing sensory experience, in particular with a melting texture and a non-greasy and non-sticky finish, allowing for high daily photoprotection.

[0017] There also remains a need for a photoprotective composition with a high level of UV protection and perfectly stable, i.e. not subject to demixing phenomena.

[0018] It has already been disclosed in patent EP 2 266 531 B1 to introduce a superabsorbent polymer into a composition comprising UV filters in order to reduce stickiness. However, the sensory qualities of the compositions thus obtained could be improved for everyday use.

[0019] The present invention is specifically designed to meet these needs. Description of the invention

[0020] The present invention therefore relates to a composition, and in particular a cosmetic or dermatological composition, comprising: a) at least one lipophilic organic UV filter; b) at least one hydrophilic organic UV filter; c) at least one charge selected from among spherical porous silica particles, in particular spherical porous silica microparticles; d) at least one filler selected from spherical cellulose particles; and e) at least one filler selected from N-acylated amino acid powders; the total quantity of fillers selected from porous silica spherical particles, cellulose spherical particles, and N-acylated amino acid powders being between 1% and 4% by weight, preferably between 2% and 4% by weight of the total weight of the composition, and the mass ratio (spherical cellulose particles + N-acylated amino acid powders) / (spherical porous silica particles) being between 0.25 and 1.

[0021] Contrary to expectations, the inventors found that the implementation, in a photoprotective composition, of one or more hydrophilic organic UV filters in combination with one or more lipophilic organic UV filters, of at least three distinct fillers, the first of which is chosen from porous silica spherical particles, in particular porous silica microparticles, the second from cellulose spherical particles, and the third from N-acylated amino acid powders, the total quantity of fillers chosen from porous silica spherical particles, cellulose spherical particles, and N-acylated amino acid powders being between 1% and 4% by weight, and the mass ratio (cellulose spherical particles + N-acylated amino acid powders) / (porous silica spherical particles) being between 0.25 and 1,This allows access to a galenic formulation with strong photoprotective power and good cosmetic properties, notably with a non-greasy finish. non-sticky and non-shiny, yet stable over time.

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

[0023] Thus, this photoprotective composition advantageously allows the combination of properties that 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 keratinous materials, in particular of the skin of the body and / or face.

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

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

[0028] The composition according to the invention exhibits 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), 4°C, 45°C, or 55°C. A stable composition generally retains its pleasantness and sensory signature upon application over time. More specifically, the stability of a composition can be assessed qualitatively, for example, by the absence of phase separation or crystal formation, or quantitatively by monitoring the evolution of parameters such as viscosity or pH.

[0029] For the purposes of this invention, "SPF" (Sun Protection Factor) means the sun protection factor, which measures the level of protection against UVB radiation. The SPF value corresponds to the ratio between the minimum time required to obtain a sunburn with a sunscreen 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).

[0030] The SPF (Sun Protection Factor) can be evaluated in vitro using a Labsphere® spectrophotometer. The plate is the material onto which the communication is applied. anti-sun position. For this protocol, polymethyl methacrylate (PMMA) sheets proved ideal.

[0031] The evaluation of the Sun Protection Factor (SPF) of the compositions can also be carried out in-vivo according to the ISO / EN 24444 protocol “Cosmetics-Sun protection test methods-In-vivo determination of the sun protection factor (SPF) (2010)”.

[0032] For the purposes of the present invention, "PPD" (Persistent Pigment Darkening) means the index characterizing protection against UVA radiation. In particular, "PPD" measures the skin color observed 2 to 4 hours after UVA exposure. This method has been adopted since 1996 by the Japanese Cosmetic Industry Association (JCIA) as the official testing procedure for UVA labeling of products and is frequently used by testing laboratories in Europe and the United States; (Japan Cosmetic Industry Association Technical Bulletin. Measurement Standards for UVA protection efficacy. Issued November 21, 1995 and effective January 1, 1996).

[0033] Other features, aspects and advantages of the invention will become apparent from the detailed description that follows.

[0034] The composition according to the invention is intended for topical application and therefore contains a physiologically acceptable medium. Hereinafter, "physiologically acceptable medium" means a medium compatible with keratinous materials.

[0035] In the context of the present invention, "keratinic material" means in particular the skin, the scalp, keratinic fibers such as eyelashes, eyebrows, hair, and body hair, nails, mucous membranes such as lips, and more particularly the skin and mucous membranes (body, face, eye contour, eyelids, lips, preferably body, face and lips).

[0036] In what follows, and unless otherwise indicated, the bounds of a range of values ​​are included in that range, in particular in the expressions "between" and "ranging from ... to ...".

[0037] Furthermore, the expressions "at least one" and "at least" used in this description are respectively equivalent to the expressions "one or more" and "greater than or equal to".

[0038] By "prevent" or "prevention", according to the invention, means 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 keratinous material.

[0039] 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 also capable of absorbing UVB radiation in the wavelength range between 280 and 320 nm.

[0040] By "organic UVB filter", we mean any organic chemical molecule capable of exclusively absorbing UVB radiation in the range of wavelengths between 280 and 320 nm.

[0041] According to a particular embodiment of the invention, the composition is in the form of an emulsion.

[0042] The term "emulsion" means any macroscopically homogeneous, kinetically stable composition comprising at least two immiscible phases; 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.

[0043] A distinction is made between so-called "direct" oil-in-water emulsions, consisting of a continuous aqueous dispersing phase and a discontinuous dispersed oily phase, and so-called inverse water-in-oil emulsions, consisting of a continuous oily dispersing phase and a discontinuous dispersed aqueous phase. Multiple emulsions also exist, such as water-in-oil-in-water or oil-in-water-in-oil emulsions. Detailed description of the invention UV filters

[0098] When the composition according to the invention includes inorganic UV filters, titanium oxide pigments, coated or uncoated, are particularly preferred.

[0099] According to the invention, the composition is free of inorganic filters.

[0100] By "free of inorganic UV filters", for the purposes of the present invention, means an amount of inorganic UV filters less than 2% by weight, preferably less than 1% by weight, and even more preferably less than 0.5% by weight relative to the total weight of the composition.

[0101] According to a particular embodiment of the invention, the total quantity of hydrophilic organic UV filters in the composition is greater than or equal to 5% by weight of the total weight of the composition.

[0102] According to a preferred embodiment, the total quantity of hydrophilic organic UV filters is between 5% and 15% by weight of the total weight of the composition.

[0103] According to a particular embodiment, the total quantity of UV filters present in the composition is greater than or equal to 15% by weight of the total weight of the composition. According to a preferred embodiment, the total quantity of UV filters present in the composition is between 15% and 35% by weight, preferably between 18% and 25% by weight of the total weight of the composition.

[0104] For the purposes of this invention, "total quantity of UV filters" means the sum of the concentrations of each of the UV filters present in the composition, in particular lipophilic organic UV filters, hydrophilic organic UV filters, and inorganic UV filters. Charges

[0105] The composition comprises at least one filler selected from spherical porous silica particles, in particular spherical porous silica microparticles, at least one filler selected from spherical cellulose particles, and at least one filler selected from N-acylated amino acid powders.

[0106] The total quantity of fillers selected from porous silica spherical particles, cellulose spherical particles, and N-acylated amino acid powders is between 1% and 4% by weight, preferably between 2% and 4% by weight of the total weight of the composition.

[0107] The mass ratio (spherical cellulose particles + N-acylated amino acid powders) / (spherical porous silica particles) is between 0.25 and 1.

[0108] By charge, we must understand particles of any shape, colorless or white, mineral or synthetic, insoluble in the medium of the composition regardless of the temperature at which the composition is manufactured.

[0109] The charges used in the present invention can be characterized by their specific surface area per unit mass or per unit volume, their size expressed in volume mean diameter D(4.3), their uncompacted density, and / or their oil absorption capacity.

[0110] The specific surface area per unit mass can be determined by the nitrogen absorption method known as the BET (BRUNAUER-EMMET-TELLER) method, 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.

[0111] 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.

[0112] In the context of the present invention, this density can be assessed according to the following protocol, known as the packed density protocol:

[0113] 40 g of powder is poured into a graduated cylinder; the cylinder is then placed on the STAMPF VOLUMETER ST AV 2003 apparatus; the cylinder is then subjected to a series of 2500 compactions (this operation is repeated until the volume difference between two consecutive tests is less than 2%); the final volume Vf of compacted powder is then measured directly on the cylinder. The compacted density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm³ and m in g).

[0114] The oil absorption capacity measured at the Wet Point, and noted Wp, corresponds to the amount of oil that must be added to 100 g of particles to obtain a homogeneous paste.

[0115] It is measured according to the so-called Wet Point method or method for determining oil uptake of powder 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 measurement of the Wet Point, described below.

[0116] A quantity m = 2 g of powder is placed on a glass plate, and oil (isononyl isononanoate) is added drop by drop. After adding 4 to 5 drops of oil to the powder, the mixture is stirred with a spatula, and oil is continued to be added until clumps of oil and powder form. From this point on, the oil is added one drop at a time, and the mixture is then triturated with the spatula. The addition of oil is stopped when a firm, smooth paste is obtained. This paste should spread easily on the glass plate without cracking or lumps. The volume Vs (expressed in mL) of oil used is then recorded.

[0117] The oil intake corresponds to the ratio Vs / m.

[0118] The particle sizes can be measured by static light scattering using a commercial particle size analyzer such as the Malvern MasterSizer 2000. The data are processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows for the determination of an "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0119] According to a particular embodiment, the fillers that can be used in the present invention have an oil absorption capacity of 0.25 g / g to 3.5 g / g, preferably from 0.93 g / g to 2.5 g / g, or even from 1.25 g / g to 2.5 g / g.

[0120] According to a particular embodiment, the charges that can be used in the present invention have a size expressed in average volume diameter D(4,3) ranging from 0.1 pm to 40 pm, preferably from 0.5 pm to 20 pm, and even more preferably from 1 pm to 16 pm.

[0122] According to a particular embodiment, they have a specific surface area ranging from 30 to 1000 m2 / g, and more particularly from 150 to 800 m2 / g.

EXAMPLES

[0235] The present invention will now be described more specifically by means of examples, which are in no way limiting to the scope of the invention. However, the examples allow for the support of specific features, variants, and preferred embodiments of the invention.

[0236] In these examples, the quantities of ingredients present in the compositions are given as % by weight of raw materials in relation to the total weight of the composition. Sensory evaluation

[0237] The cosmetic properties are evaluated by four individuals trained in describing skincare products and familiar with the Playtime & Touch protocol. The sensory evaluation of the skincare products by this panel is conducted as follows: the products are packaged in jars and tested on SkinFX synthetic skin. During the same session, the samples are presented simultaneously to each panelist. The experts place a drop of product (0.05 mL) on the back of their hand and spread the product for 15 seconds. After another 15 seconds, the spreading is repeated for a further 15 seconds.

[0238] Descriptors of slipperiness, stickiness, grease (amount of film-forming substance on the fingers) and brightness are evaluated after a total of 2 minutes and 45 seconds.

[0239] These descriptors are evaluated on a scale of 1 to 5: 1 = not at all, 2 = slightly, 3 = moderately, 4 = fairly, 5 = very, and the rating reflects expert consensus. For the Slipperiness and Shine descriptors, the rating for bare skin is 3. Stability study

[0240] The stability of the compositions is evaluated macroscopically (Appearance, Colour, Odour, pH and viscosity) and microscopically at 1 week at 55 °C, and at 1 month at 4 °C, 25 °C and 45 °C.

[0241] Macroscopic stability is assessed with the naked eye and microscopic stability is assessed using an optical microscope in white light. Protocol for evaluating filtering efficiency

[0242] In-vitro: The sun protection factor (SPF) is determined according to the "in vitro" method described by BL Diffey in J. Soc. Cosmet. Chem. 40, 127-133, (1989). The measurements were carried out using a UV-1000S spectrophotometer from Labsphere.

[0243] The in vitro UVA protection factor (PPD) of a sun protection product against UVA radiation calculated mathematically by in vitro spectral modelling according to the ISO 24443:2012 (Fr) protocol.

[0244] Each composition is applied to six rough PMMA plates as a homogeneous and regular deposit at a rate of 1 mg / cm². The spreading of each composition is carried out using an automated robot that makes regular and uniform movements on three HD6 plates (molded granular plates) and three SB6 plates (sandblasted granular plates). The plate is weighed before and after spreading. Once the six plates are spread, they are placed in Thermo-Master chambers in the dark at 25°C for 30 minutes. Measurements are performed using the Labsphère UV-1000S spectrophotometer. Nine measurements are taken per plate, and the measurements are then analyzed using an Excel spreadsheet, which provides the SPF and PPD values ​​for the measured composition.
