Description

Title of the invention: Cosmetic or dermatological composition comprising a merocyanine and at least one diol comprising 4 to 7 carbon atoms

[0001] The present invention relates to a cosmetic or dermatological composition comprising at least one merocyanine of formula (3) which will be defined in detail below and at least one diol comprising from 4 to 7 carbon atoms, the composition being free of isohexadecane and styrenic polymer.

[0002] The present invention also relates to a non-therapeutic cosmetic process for caring for and / or making up a keratin material comprising the application to the surface of said keratin material of at least one composition according to the invention as defined above.

[0003] 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.

[0004] 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.

[0005] It is known that radiation with a wavelength between 280 nm and 400 nm allows the tanning of the human epidermis and that radiation with a wavelength between 280 and 320 nm, known as UV-B rays, harms the development of natural tanning. Exposure is also likely to induce an alteration of the biomechanical properties of the epidermis which results in the appearance of wrinkles leading to premature aging of the skin.

[0006] It is also known that UV-A rays with a wavelength between 320 and 400 nm penetrate deeper into the skin than UV-B rays. UV-A rays cause immediate and persistent browning of the skin. Daily exposure to UVA rays, even for short periods, under normal conditions can lead to a degradation of collagen and elastin fibers which results in a change in the micro-relief of the skin, the appearance of wrinkles and irregular pigmentation (brown spots, uneven skin tone).

[0007] Protection against UVA and UVB radiation is therefore necessary. An effective photoprotection product must protect against both UVA and UVB radiation.

[0008] Many photoprotective compositions have been proposed to date to remedy the effects induced by UVA and / or UVB radiation. They generally contain organic UV filters and / or inorganic UV filters which function according to their own chemical nature and according to their own properties by absorption, reflection, or diffusion of UV radiation. They generally contain mixtures of fat-soluble organic filters and / or water-soluble UV filters associated with metal oxide pigments such as titanium dioxide or zinc oxide.

[0009] Many cosmetic compositions intended to limit the darkening of the skin, improve the color and homogeneity of the complexion have been proposed to date. It is well known in the field of sunscreens that such compositions can be obtained by using UV filters, and in particular UVB filters. Some compositions may also contain UVA filters. This filtering system must cover UVB protection in order to limit and control the neosynthesis of melanin promoting overall pigmentation, but must also cover UVA protection in order to limit and control the oxidation of the already existing melanin leading to the darkening of the skin color.

[0010] However, it is extremely difficult to find a composition containing a particular combination of UV filters which would be specially adapted to the photoprotection of the skin and particularly to an improvement in the quality of the skin both in terms of color and its mechanical properties of elasticity.

[0011] Advantageously, this improvement is particularly sought on already pigmented skin with the aim of not increasing either the pigment load in melanin or the structure of the melanin already present within the skin.

[0012] In fact, the majority of organic UV filters consist of aromatic compounds absorbing in the wavelength range between 280 and 370 nm. In addition to their solar radiation filtering power, the desired photoprotection compounds must also have good cosmetic properties, good solubility in common solvents and in particular in fatty substances such as oils, as well as good photostability alone or in combination with other UV filters. They must also be colorless or at least have a color that is cosmetically acceptable to the consumer.

[0013] One of the main drawbacks known to date of these compositions is that these filtering systems have insufficient effectiveness against UV radiation and particularly against long UVA radiation with wavelengths beyond 370 nm in order to control photo-induced pigmentation and its development by a system filtering UV over the entire UV spectrum.

[0014] Among all the compounds that have been recommended for this effect, a interesting family of UV filters which consists of carbon merocyanine derivatives which is described in patent US4195999, application WO2004 / 006878 and document IP COM Journal 4 (4), 16 N°IPCOM000011179D published on 04 / 03 / 2004. These compounds have very good filtration properties in long UVA radiation but have a poorly satisfactory solubility in the usual solvents, both in aqueous phase and in fatty phase, and unsatisfactory photo-stability for certain merocyanines.

[0015] In order to search for other merocyanines having better solubility in usual solvents and better photostability, application WO2013 / 011094 proposed merocyanines comprising polar groups consisting of hydroxyl and ether functions which show good long UVA filtration efficiency. However, the solubility of these particular merocyanines is not yet fully satisfactory, and often requires a tedious formulation process. Furthermore, the large quantities of solvent required to solubilize this type of merocyanine can lead to cosmetic problems such as a sticky and greasy effect upon application.

[0016] There therefore remains a need to improve the solubility of these merocyanines in cosmetic compositions, in particular photo-protective formulations, both in aqueous phase and in fatty phase, while obtaining good cosmeticity.

[0017] Furthermore, more and more raw materials are becoming undesirable in cosmetics due to their reputation, rightly or wrongly, of having a toxicological profile that is not very favorable to the environment, which may be the case for certain solvents of petrochemical origin or for microplastic particles.

[0018] The Applicant has surprisingly discovered that by using certain suitably selected diols, it is possible to significantly improve the solubility of these merocyanines both in an aqueous phase and in a fatty phase. This discovery is the basis of the present invention.

[0019] Thus, in accordance with one of the objects of the present invention, there is now provided a cosmetic or dermatological composition comprising at least one merocyanine of formula (3) which will be defined in detail below and at least one diol comprising from 4 to 7 carbon atoms, the composition comprising less than 2% by weight of isohexadecane and less than 2% by weight of styrenic polymers.

[0020] According to a particular embodiment, the composition in accordance with the invention comprises less than 1% by weight of isohexadecane and less than 1% by weight of styrenic polymers, preferably less than 0.5% by weight of isohexadecane and less than 0.5% by weight of styrenic polymers. According to a preferred embodiment, the composition in accordance with the invention is free of isohexadecane and styrenic polymers.

[0021] Furthermore, there is also a need to improve the solubility of merocyanines in the presence of organic filters. Indeed, the addition of additional filters can destabilize compositions comprising a merocyanine.

[0022] The Applicant has surprisingly discovered that by using at least one diol comprising 4 to 7 carbon atoms, it is possible to significantly improve the solubility of these merocyanines in an aqueous phase or in a fatty phase, even in the presence of additional organic UV filters.

[0023] The Applicant has also discovered that the use of at least one diol comprising from 4 to 7 carbon atoms makes it possible to obtain good cosmeticity of the composition comprising the merocyanines, the latter being in particular non-greasy and non-sticky.

[0024] The present invention also relates to a non-therapeutic cosmetic process for caring for and / or making up a keratin material comprising the application to the surface of said keratin material of at least one composition according to the invention as defined above.

[0025] 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.

[0026] 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.

DOSAGE FORMS

[0182] The compositions in accordance with the invention may be aqueous or anhydrous.

[0183] When the compositions are aqueous, they contain at least one aqueous phase.

[0184] They can then be in purely aqueous form, that is to say they comprise a quantity of fatty phase less than 10% by weight, preferably less than 5% by weight, and even more preferably less than 2% by weight relative to the total weight of the composition. Advantageously, the composition in accordance with the invention is essentially aqueous, that is to say it is free of phase fat.

[0185] The compositions according to the invention may also be presented in particular in the form of an emulsion, simple or complex (O / W, W / O, O / W / O or W / O / W) such as a cream, a milk or a cream gel.

[0186] In the case where the composition in accordance with the invention is aqueous, and it is possible to measure its pH, this is generally between approximately 3 and 12, preferably between approximately 5 and 9, and even more particularly from 5.5 to 8.

[0187] The compositions may also be in anhydrous form, such as for example in the form of an oil, an alcoholic solution or a glycolic solution. The term "anhydrous composition" means a composition containing less than 1% by weight of water, or even less than 0.5% of water, and in particular free of water, the water not being added during the preparation of the composition but corresponding to the residual water provided by the mixed ingredients. They may optionally be packaged as an aerosol and be in the form of a foam or spray.

[0188] In the case of compositions in the form of oil-in-water or water-in-oil emulsions, the emulsification processes that can be used are of the blade or propeller, rotor-stator and HHP type.

[0189] To obtain stable emulsions with a low polymer content (oil / polymer ratio >25), it is possible to make the dispersion in concentrated phase then dilute the dispersion with the rest of the aqueous phase.

[0190] 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.

[0191] The emulsions 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).

[0192] As examples of W / O emulsifying surfactants, mention may be made of alkyl esters or ethers of sorbitan, glycerol, polyol, glycerol or sugars; silicone surfactants such as dimethicone copolyols such as the mixture of cyclomethicone and dimethicone copolyol, sold under the name "DC 5225 C®" by the company Dow Corning, and alkyl-dimethicone copolyols such as Laurylmethicone copolyol sold under the name "Dow Corning 5200 Formulation Aid" by the company Dow Corning; Cetyl dimethicone copolyol such as the product sold under the name Abil EM 90R® by the company Goldschmidt and the mixture of cetyl dimethicone copolyol, polyglycerol isostearate (4 moles) and hexyl laurate sold under the name ABIL WE 09® by the company Goldschmidt.

[0196] For H / W emulsions, examples of non-ionic emulsifying surfactants that may be mentioned are polyoxyalkylenated (more particularly polyoxyethylenated and / or polyoxypropylenated) glycerol fatty acid esters; oxyalkylenated sorbitan fatty acid esters; polyoxyalkylenated (in particular polyoxyethylenated and / or polyoxypropylenated) fatty acid esters, optionally in combination with a glycerol fatty acid ester such as the PEG-100 Stearate / Glyceryl Stearate mixture marketed, for example, by the company ICI under the name Arlacel 165; oxyalkylenated (oxyethylenated and / or oxypropylenated) fatty alcohol ethers; sugar esters such as sucrose stearate; fatty alcohol and sugar ethers, in particular alkylpolyglucosides (APG) such as decylglucoside and laurylglucoside marketed for example by Henkel under the respective names Plantaren 2000® and Plantaren 1200®,cetostearylglucoside optionally in a mixture with cetostearyl alcohol, marketed for example under the name Montanov 68® by the company Seppic, under the name Tegocare CG90® by the company Goldschmidt and under the name Emulgade KE3302® by the company Henkel, as well as arachidyl glucoside, for example in the form of the mixture of arachidic and behenic alcohols and arachidylglucoside marketed under the name Montanov 202® by the company Seppic. According to a particular embodiment of the invention, the mixture of the alkylpolyglucoside as defined above with the corresponding fatty alcohol may be in the form of a self-emulsifying composition, as described for example in document WO-A-92 / 06778.

[0197] When it is an emulsion, the aqueous phase thereof may comprise a non-ionic vesicular dispersion prepared according to known methods (Bangham, Standish and Watkins. J. Mol. Biol. 13, 238 (1965), FR 2 315 991 and FR 2 416 008).

[0282] Method of preparation

[0283] Phase A1 is prepared by mixing all the ingredients until a clear phase is obtained. Phase A2 is dispersed and then phase A3 is added to neutralize the gel and allow it to unfold. All of this preparation of the phase which will subsequently be called A is carried out by heating to 65°C and stirring with paddles (50 rpm).

[0284] Phase B1 is prepared by mixing all the ingredients while heating at 80°C with magnetic stirring until a clear and homogeneous phase is obtained. Phase B2 is then dispersed in Bl. This phase will be called phase B.

[0285] The emulsification is carried out by dispersing phase B in phase A at 65°C and with vigorous stirring (blades at 80 rpm and turbine at 11,000 rpm) for 5 minutes. An oil-in-water emulsion is obtained. The temperature of the mixture is then gradually reduced to return to room temperature while maintaining the same stirring until the end. Around 55°C, the thickeners of phase C1 are added (5 minutes), then neutralized with C2 to deploy the gels (5 minutes). The fillers of phase D are dispersed (5 minutes) from 35°C. Finally, the alcohol of phase E is added once the mixture has returned to room temperature.
