Description

COMPOSITION CONTAINING DIBENZOYLMETHANE DERIVATIVE, LIPOPHILIC 2-HYDROXYBENZOPHENONE AND SILICATED S-TRIAZINE; PHOTOSTABILIZATION METHOD

The present invention relates to a composition comprising in a cosmetically acceptable support at least one UV filtering system, characterized in that it comprises: (i) a dibenzoylmethane derivative: (i) at least one UV filter of 2-hydroxybenzophenone type lipophilic; (iii) at least one siliconized s-triazine substituted with at least two alkylaminobenzoate groups of formula (III) which will be defined below in detail.

It also relates to a process for photostabilizing the radiation of at least one dibenzoylmethane derivative type filter by an effective amount of at least one lipophilic 2-hydroxybenzophenone type UVA filter and at least one a siliciated s-triazine substituted with at least two aminobenzoate or aminobenzamide groups of formula (III) defined below.

It is known that the luminous radiations of wavelengths between 280 nm and 400 nm allow the browning of the human epidermis and that the wavelength rays between 280 nm and 320 nm, called UV-B radiation, cause erythema and skin burns that can interfere with the development of natural tanning; this UV-B radiation must therefore be filtered.

It is also known that UV-A rays of wavelengths between 320 nm and 400 nm are capable of inducing an alteration of the skin, in particular in the case of sensitive skin or a continuously exposed skin. to solar radiation. UV-A rays cause in particular a loss of elasticity of the skin and the appearance of wrinkles leading to premature aging. They promote the triggering of the erythematous reaction or amplify this reaction in some subjects and may even be the cause of phototoxic or photoallergic reactions. It is therefore desirable to filter the UV-A radiation as well.

Numerous cosmetic compositions intended for the photoprotection (UV-A and / or UV-B) of the skin have been proposed to date.

These sunscreen compositions are often in the form of an oil-in-water or water-in-oil emulsion, gels or anhydrous products which contain, at various concentrations, one or more organic and / or or inorganic. These filters and their quantities are selected according to the desired protection index. In this respect, a particularly interesting family of filters currently consists of the dibenzoylmethane derivatives, and especially 4-tert-butyl-4'-methoxydibenzoylmethane. These dibenzoylmethane derivatives are products that are well known per se as active filters in UV-A and are described in particular in French patent applications FR-A-2326405 and FR-A-2440933, as well as in the patent application. European EP-A-0114607.

Unfortunately, it turns out that the dibenzoylmethane derivatives are relatively sensitive to ultraviolet radiation (especially UV-A), that is to say, they degrade more or less rapidly under the action of the latter. Thus, this substantial lack of photochemical stability vis-à-vis the ultraviolet radiation to which they are inherently intended to be subjected, does not guarantee a constant protection during prolonged exposure to sunlight. Several means of photostabilization of the dibenzoylmethane derivatives are known to date. Thus, it is known in the patent application EP0514491 that the alkyl (3, 13'-diphenylacrylate or α-cyano (3, 13'-diphenylacrylate) derivatives substantially improves the photostability of the dibenzoylmethane derivatives. have a good efficiency vis-à-vis the improved photostability of dibenzoylmethane derivatives, they nonetheless have a low UV-B absorbency.

It is also known in patent application EP1280505 that Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine alone improves the photostability of dibenzoylmethane derivatives. Unfortunately, although this filter has a high UV-B absorbing capacity, it nevertheless has limited effectiveness with regard to improving the photostability of the dibenzoylmethane derivatives, as well as a limited solubility in oils.

It has also been proposed in applications EP0843996 and EP0864313 to improve the photostability of a dibenzoylmethane derivative by a lipophilic 2-hydroxybenzophenone such as 2-hydroxy-4-methoxybenzophenone or benzophenone-3. This combination does not make it possible to obtain a sufficient photostability of the dibenzoylmethane nor to obtain a broad coverage of the UV spectrum.

Also known in patent applications EP1323411 and US66899461 describing sunscreen compositions containing an aminosubstituted 2-hydroxybenzophenone derivative associated with a dibenzoylmethane derivative in a ratio by weight of the aminosubstituted 2-hydroxybenzophenone derivative on the dibenzoylmethane derivative greater than 1 Unfortunately, if this combination has improved photostability, it is strongly limited to the ratio of the two filters and does not allow to obtain a broad coverage of the UV spectrum.

It has also been proposed in application EP1891079 to improve the photostability of the dibenzoylmethane derivatives by siliconized s-trazines substituted with at least two alkylaminobenzoate or alkylaminobenzamide groups. The Applicant's research has found that some of these compounds triazine silicones especially those having alkylaminobenzoate groups whose alkyl chain has more than 10 carbon atoms did not achieve sufficient efficiency. 50 The good photostabilization of dibenzoylmethane derivatives with respect to UV radiation, combined with a good protective efficacy in UVB to be able to provide complete and effective protection of the skin in the face of exposure to UV radiation is, to date, a problem that has not yet been solved in a completely satisfactory manner.

However, the Applicant has now discovered, surprisingly, that the use of an active filter in the UV-B of s-triazine siliconized substituted with two aminobenzoate groups of formula (III) which will be defined more In detail, in combination with a lipophilic 2-hydroxybenzophenone UVA filter in the presence of a dibenzoylmethane derivative, it was possible to solve the technical problems mentioned above.

Indeed, such a combination of filters makes it possible, on the one hand, to obtain a good level of protection (broad coverage of the UV spectrum and sufficiently high solar protection indices) and, on the other hand, to substantially reduce the phenomena of photodegradation of the dibenzoylmethane derivatives with which they are associated in sunscreen products.

The sunscreen compositions containing such a combination of organic UV filters also have good persistence to water, perspiration and washes as well as good persistence over time.

This discovery is the basis of the present invention. Thus, according to one of the objects of the present invention, there is now provided a composition comprising in a cosmetically acceptable support at least one UV filtering system, characterized in that it comprises: (i) at least one derivative of dibenzoylmethane; (ii) at least one lipophilic 2-hydroxybenzophenone type UV filter; and (iii) at least one siliconized s-triazine substituted with at least two alkylaminobenzoate groups of formula (III).

It also relates to a process for photostabilizing the radiation of at least one dibenzoylmethane type filter by an effective amount of at least at least one lipophilic 2-hydroxybenzophenone type filter and at least one sodium s-triazine substituted with at least two aminobenzoate or aminobenzamide groups of formula (III) defined below.

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

By "cosmetically acceptable" is meant compatible with the skin and / or its integuments, which has a pleasant color, smell and feel and which does not generate unacceptable discomfort (tingling, tightness, redness), which can divert the consumer to use this composition.

By "lipophilic compound" is meant any cosmetic or dermatological compound capable of being completely dissolved in the molecular state in a liquid fatty phase or to be solubilized in colloidal form (for example in micellar form) in a liquid fatty phase.

An effective amount is understood to mean an amount sufficient to obtain a significant and significant improvement in the photostability of the dibenzoylmethane derivative (s) in the cosmetic composition. This minimum amount of 2-hydroxybenzophenone lipophilic and s-triazine silicon of formula (III), which may vary depending on the nature of the support selected for the composition, can be determined without any difficulty by means of a conventional measurement test photostability, such as that given in the examples below.
