Description

The present invention relates to a solid anhydrous cosmetic composition, especially in the form of "hot casting", comprising in particular a liquid fatty phase, a wax, and organic UV filters. The composition may be a make-up or skincare composition for keratin materials such as the skin, the eyelids, the lips, and especially the skin. The invention also relates to a process for making up or caring for keratin materials. Skincare or make-up products are known in the form of various galenics: fluid or thick cream, lotion, stick, cast solid product, loose powder, compact powder. The cast solid products may be anhydrous and generally contain fatty substances such as oils and solid waxes, and possibly a particulate phase generally composed of fillers and pigments, as described for example in the applications FR2979236, US-A-2011 / 033512, EP-A-850644, FR-A2873031. The compositions in the form of "hot casting" can be applied satisfactorily using the fingers or an applicator, from a packaging in the form of a cup or a stick. Some cosmetic products contain UV filters (sunscreens) to protect the skin from damage caused by UV-A radiation (wavelength between 320 and 400 nm) and UV-B (wavelength between 280 and 320 nm). UV-A rays cause immediate and persistent browning of the skin. Daily exposure to UVA rays, even for short periods of time, under normal conditions can lead to collagen and elastin fiber degradation which results in a change in skin microrelief, wrinkling and irregular pigmentation. (brown spots, heterogeneity of the complexion). UV-B rays can induce an alteration of the biomechanical properties of the epidermis which results in the appearance of wrinkles leading to premature aging of the skin.

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

However, the introduction of some organic UV filters in a large amount (more than 5% by weight of the composition) in an anhydrous solid composition causes stability problems: the UV filter can recrystallize, cracks can appear on the surface of the product solid making its appearance unattractive. The cosmetic properties of the composition may be impaired, in particular because of a difficulty of spreading the composition over the skin, conferring discomfort on the application. If a large quantity of mineral UV filters (titanium dioxide) are incorporated, the resulting product may have a plastery appearance and give a dry appearance when applied to the skin.

There is therefore a need to have an anhydrous solid composition which makes it possible to effectively protect the skin against UV radiation while having good properties of stability and good cosmetic properties.

The inventors have demonstrated that by combining, in a solid anhydrous cosmetic composition, a non-volatile oil, a wax and a mixture of four UV filters as defined below, it is possible to obtain a solid composition having good stability, especially after storage for 2 months at room temperature (25 ° C.) and at 45 ° C. (no recrystallization, no surface cracking, homogeneous composition). The composition also has good cosmetic properties, especially when it is applied to keratin materials such as the skin, in particular good spreading. The composition does not have a plastery appearance, especially after its application to keratin materials. The texture of the composition is not dry, and does not present discomfort after its application on the skin.

In addition, the composition has a good efficacy in photoprotection. The present invention therefore relates to a solid anhydrous cosmetic composition comprising at least one liquid fatty phase containing at least one non-volatile oil, at least one wax, and at least one mixture of organic UV-screening agents comprising (or consisting essentially of) a UV-salicylate filter. , a bis-resorcinyl triazine UV filter, a UV filter [343-diphenylacrylate and a benzotriazole UV filter. The invention also relates to a process for the makeup and / or care of keratinous substances, in particular the skin or the lips, comprising at least one step consisting in applying to a keratin material, in particular the skin and / or the lips, a composition as defined according to the invention.

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

By anhydrous composition within the meaning of the present application means a composition comprising less than 5% by weight of water, relative to the total weight of the composition, preferably less than 2% by weight of water. More preferably still, the composition is 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. The composition is, in accordance with the invention, in solid form. By "solid" is meant a composition which has a hardness such that it does not flow at room temperature under its own weight, especially after 5 minutes, as opposed to so-called fluid compositions. Such a composition is advantageously obtained by hot-casting and cooling. The cohesion is thus ensured by solidification of at least one of its constituents during the implementation. Cast cosmetic products are particularly appreciated in the field of makeup, because of their ease of use, the infinity of shapes they can wear, and their stability related to their solid nature. As an illustration of these cast products can be cited in particular sticks used to make up the lips and face, especially cheekbones or dark circles, but also products cast in cups commonly called "hot cast" for face makeup or older than the eyelashes or eyebrows. Solid products are also interesting for skin care products, such as lip care sticks.
