FR 3 060 357 - A1 (□ 4) COMPOSITION COMPRISING BAICALIN AND AN ORGANIC UV FILTER PRESENT IN AN ENCAPSULATED FORM.

©) The present invention relates to a composition, preferably cosmetic, comprising at least one aqueous phase containing:

- a compound chosen from baicalin and its derivatives, or a plant extract containing at least one of said compounds; and

- at least one organic UV filter present in an encapsulated form.

It also relates to the use of such a composition for protecting the skin and / or the lips and / or the hair against solar radiation or for combating or preventing the signs of premature photo-induced aging of the skin. and / or lips and / or hair.

i

The present application relates to a composition for topical application comprising baicalin and / or one of its derivatives or an extract containing and reuse of said composition in the field in particular cosmetic and in particular for care, hygiene , protection and / or make-up of keratinous materials, such as the skin, in particular of the body or of the face, or the hair, preferably for the care of the skin of the body or of the face.

The present invention relates in particular to the field of photoprotective cosmetic compositions, also called sun products or photoprotective products, as well as corresponding cosmetic treatment methods.

Keratin materials, and in particular the skin, are exposed to sunlight daily.

However, it is known that prolonged exposure of the skin to this polychromatic light is capable of inducing skin disorders or even surface damage.

In particular, because of this exposure, some people see appearing on the skin, and more particularly on the face, the neckline, the arms, the hands and the shoulders, darker and / or more colored spots, giving the skin a heterogeneity which, for obvious reasons, poses an aesthetic problem.

To counter these undesirable effects, it is common practice to use photoprotective compositions in which organic or inorganic anti-UV filters are formulated.

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.

UVA filters advantageously make it possible to filter UV-A radiation, of wavelength between 320 and 400 nm, which causes browning of the skin and is capable of inducing an alteration thereof, in particular in the case of '' sensitive skin or skin continuously exposed to solar radiation. UV-A radiation in particular causes a loss of elasticity in the skin and the appearance of wrinkles, thereby leading to premature aging of the skin.

UVB filters allow to filter UV-B radiation, wavelength between 280 and 320 nm, which also allows browning of the epidermis but is likely to cause erythema and superficial burns of the skin which can interfere with natural tanning.

It is thus customary to introduce UVA filters and / or UVB filters, in particular UVA organic filters and / or UVB organic filters, in compositions dedicated to imparting sun protection.

However, the presence of these filters in compositions has cosmetic drawbacks on application, such as a greasy and sticky feeling.

Many cosmetic compositions comprising baicalin as an antioxidant or as a photoprotective, or an extract containing it, are known in the state of the art.

This is apparent in particular from several publications and patents such as patent application IP 63083017 relating to the filtering action of certain compounds including baicalin. The publications Shengzhao et al. (Study of application ofbaicalin in functional cosmetics, Riyong Huaxue Gongye (2003), 33 (3), 200-203) and Feng-jiao et al. (Technology for preparation of sunscreen cream containing baicalin, Riyong Huaxue Gongye (2009), 39 (4), 257-259) also relate to cosmetic compositions, and more particularly sunscreen compositions, containing baicalin.

Patent application DE 102009037900 also describes a cosmetic composition comprising baicalin in combination with different active ingredients. This document also describes the possible additional presence of UV screening agents, but without any specific conclusion in this regard.

Consequently, these photoprotective compositions comprising baicalin are still to be improved from the point of view of the protection of the skin from solar radiation, and in particular from UV rays.

Thus, it would be desirable to obtain a composition comprising baicalin and having UV protection and pleasant cosmetic properties, such as an absence of tights and fat.

One solution would be to combine baicalin with an aqueous phase filtering system. However, the water-soluble filters (UVB and UVA) are very limited and have incompatibilities with baicalin, or do not make it possible to obtain a composition with the required properties.

For example, Eusolex 232, in salt form, has a pH incompatibility with baicalin. Indeed, it has been identified that the final pH of a composition making it possible to ensure the chemical stability of baicalin is less than 6, which leads to the crystallization of Eusolex 232. At a pH greater than 6, the baicalin is chemically unstable and degrades.

Other filters, such as Mexoryl SX, provide weak UVB protection and add a lot of stickiness to the product.

There therefore therefore remains in particular a need for a stable cosmetic composition comprising baicalin, or an extract containing it, which is neither sticky nor greasy and which has good efficacy against solar radiation in particular against UV rays and in particular a satisfactory Sun Protection Factor (SPF).

The object of the present invention is to satisfy these needs.

Thus, according to a first aspect, the present invention relates to a composition, preferably cosmetic, comprising at least one aqueous phase containing:

- a compound chosen from baicalin and its derivatives, or a plant extract containing at least one of said compounds; and

- at least one organic UV filter present in an encapsulated form.

In particular, the composition according to the invention is a photoprotective composition. It is more particularly intended for topical use.

The compositions according to the invention are advantageously stable and pleasant to apply. They are neither sticky, greasy, nor whitening, and make it possible to potentiate the filtration efficiency of UVs.

Another subject of the invention, according to another of its aspects, is a cosmetic process, comprising at least one step consisting in applying to the skin, the lips and / or the hair a composition according to the invention.

Also, the subject of the present invention is the cosmetic, non-therapeutic use of a composition according to the invention, for the protection of the skin and / or the lips and / or the hair against solar radiation.

The present invention also relates to the cosmetic, non-therapeutic use of a composition according to the invention, for combating or preventing the signs of premature photo-induced aging of the skin and / or the lips and / or the hair.

By “keratin material”, within the meaning of the present invention, is meant to cover the skin, the mucous membranes, such as the lips, the nails and the keratin fibers, like the eyelashes and the hair. The skin, the lips and / or the hair are very particularly considered according to the invention.

By "skin" is meant the entire skin of the body, including the scalp, the mucous membranes and the semi-mucous membranes, and its appendices. By "appendages of the skin" is meant the hairs, the eyelashes, the hair, and the nails. More particularly, the skin of the neckline, the neck and the face, and in particular the skin of the face, is considered in the present invention.

Within the meaning of the invention, the terms “EiVs filters” and “UV filters” have the same meaning, and designate filters filtering ultraviolet radiation. Likewise, the terms “anti-UVA filters” and “UVA filters” have the same meaning and designate filters filtering UVA. The same goes for related terms in the application to UVB filters.

For the purposes of the invention, the term sun protection factor (SPF) means the ratio between the minimum time it takes to get a sunburn with a sunscreen composition and that without product. It is expressed mathematically by the ratio of the dose of UV radiation necessary to reach the erythematogenic threshold with the UV filter against the dose of UV radiation necessary to reach the erythematogenic threshold without an UV filter. Thus, the higher the SPF of a composition, the more this composition confers a high level of sun protection.

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