Description

COMPOSITION CONTAINING DIBENZOYLMETHANE FILTER AND HYDROPHILIC OR WATER SOLUBLE MEROCYANINE UV FILTER; METHOD FOR PHOTOSTABILIZING THE DIBENZOYLMETHANE FILTER

The present invention relates to a cosmetic composition containing the combination of i) at least one filter of the dibenzoylmethane derivative type and ii) at least one hydrophilic or hydrosoluble merocyanine UV filter of formula (I) or (II) which will be defined below.

It also relates to a photostabilization process with respect to the radiation of at least one dibenzoylmethane derived type filter by an effective amount of at least one hydrophilic or hydrosoluble merocyanine UV filter of formula (I) or (II) which will be 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 more particularly between 280 and 320 nm, known under the name UV-B, cause erythema and skin burns that can affect the development of natural tanning. For these reasons as well as for aesthetic reasons, there is a constant demand for means of control of this natural tan to thereby control the color of the skin; it is therefore necessary to filter this UV-B radiation.

It is also known that UV-A rays of wavelengths between 320 and 400 nm, which cause browning of the skin, are liable to induce an alteration thereof, particularly in the case of sensitive skin or skin continuously exposed to solar radiation. UV-A rays cause in particular a loss of elasticity of the skin and the appearance of wrinkles leading to premature cutaneous aging. They promote the initiation of the erythematous reaction or amplify this reaction in certain subjects and may even be the cause of phototoxic or photoallergic reactions. Thus, for aesthetic and cosmetic reasons such as the preservation of the natural elasticity of the skin for example, more and more people wish to control the effect of UV-A on their skin. It is therefore desirable to filter the UV-A radiation as well.

In order to ensure protection of the skin and keratin materials against UV radiation, antisolar compositions comprising organic screening agents active in the UV-A and active in the UV-B are generally used. Most of these filters are fat soluble.

In this respect, a particularly interesting family of UV-A filters currently consists of the dibenzoylmethane derivatives, and in particular 4-tert-butyl-4'-methoxydibenzoylmethane, which in fact have a high intrinsic absorption power. These dibenzoylmethane derivatives, which are now products that are well known per se as active filters in UV-A, are described in particular in French patent applications FR-A-2326405 and FR-A-2440933, as well as in European Patent Application EP-A-0114607; 4-tert-butyl-4'-methoxydibenzoyl methane is also currently offered for sale under the trade name "PARSOL 1789®" by DSM NUTRITIONAL PRODUCTS.

Unfortunately, it turns out that the dibenzoylmethane derivatives are relatively sensitive to ultraviolet radiation (especially UV-A), that is to say, more precisely, that they have an unfortunate tendency to degrade more or less quickly under the action of the latter. Thus, this substantial lack of photochemical stability of the dibenzoylmethane derivatives against ultraviolet radiation to which they are inherently intended to be subjected, does not provide a constant protection during prolonged sun exposure, so that repeated Regular and close times must be performed by the user to achieve effective protection of the skin against UV rays.

In the patent application WO0128732, there is known a process for photostabilizing a dibenzoylmethane derivative with a phenyl sulphone merocyanine derivative. On the one hand, this photostabilization of the dibenzoylmethane derivative by the phenyl sulphone merocyanine derivative is not completely satisfactory. On the other hand, these merocyanine phenyl sulfone derivatives have the disadvantage of degrading in the presence of dibenzoylmethane under the influence of UV radiation.

In the patent application WO2008090066, it has already been proposed to photostabilize the dibenzoylmethane derivatives with cyclic derivatives of merocyanine cyanoacetate. Here again the light stabilization of the dibenzoylmethane derivative remains insufficient and these merocyanine cyanoacetate derivatives also have the disadvantage of being degraded in the presence of dibenzoylmethane.

The photostabilization of the dibenzoylmethane derivatives with respect to UV radiation thus constitutes, to date, a problem which has not yet been solved in a completely satisfactory manner.

However, the Applicant has now discovered, surprisingly, that by associating with the dibenzoylmethane derivatives mentioned above a hydrophilic or hydrosoluble merocyanine UV filter of formula (I) or (II), active in the UV-AI , on the one hand could substantially improve the photochemical stability (or photostability) of the dibenzoylmethane derivatives and, on the other hand, extend the filtration of the composition in the UV-A plus Long 40 while being cosmetically colored. acceptable.

This discovery is the basis of the present invention.

Thus, in accordance with one of the objects of the present invention, there is now proposed a composition comprising in a cosmetically acceptable support at least one UV filtering system, characterized in that it comprises: (i) at least one derivative dibenzoylmethane and (ii) at least one hydrophilic or hydrosoluble merocyanine UV filter of formula (I) or (II), the definitions of which will be given hereinafter.

Another subject of the invention also relates to a method for improving the chemical stability with respect to the UV radiation of at least one dibenzoylmethane derivative comprising associating with said dibenzoylmethane derivative an effective amount of at least one UV filter. hydrophilic or water-soluble merocyanine of formula (I) or (II), the definitions of which will be given 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, odor and feel and which does not generate unacceptable discomfort (tingling, tightness, redness), which can divert the consumer to use this composition.

In the following description, the term "hydrophilic UV filter" by any filtering agent UV radiation capable of being soluble in a water phase at 1-5% by weight (transparent) or water-dispersible in the form of a suspension particles smaller than 100 microns. By "water-soluble filter" by any filtering agent is meant UV radiation capable of being soluble in its cosmetically acceptable salt form in an aqueous phase greater than 5% by weight.

By "effective amount" is meant an amount sufficient to achieve a significant and significant improvement in the photostability of the dibenzoylmethane derivative (s) in the cosmetic composition. This minimum amount of a merocyanine derivative of formula (I) or (II), 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 photostability measurement test, as given in the examples below. Among the derivatives of dibenzoylmethane, mention may be made, in a nonlimiting manner: 2-methyldibenzoylmethane, 4-methyldibenzoylmethane, 4-isopropyldibenzoylmethane, 4-tert.-butyldibenzoylmethane, dimethyldibenzoylmethane, 40-2,5-dimethyldibenzoylmethane, 4,4'-diisopropyldibenzoylmethane, 4,4'-dimethoxydibenzoylmethane, 4-tert-butyl-4'-methoxydibenzoylmethane, 2-methyl-5 isopropyl-4'-methoxydibenzoylmethane, 4s - 2-methyl-5-tert-butyl-4'-methoxydibenzoylmethane, 2,4-dimethyl-4'-methoxydibenzoylmethane, 2,6-dimethyl-4-tert butyl-4'-methoxydibenzoylmethane.
