Definitions
- the present invention relates to new cosmetic compositions for topical use, more particularly intended for the photoprotection of the skin and / or the hair against ultraviolet radiation (compositions hereinafter referred to more simply as sunscreen compositions), as well as their use in cosmetic application. above. More precisely still, it relates to sunscreen compositions comprising, in a cosmetically acceptable support, a combination of at least two particular filters, namely on the one hand weight of an organic, insoluble UV filter with particle size ranging from 10 nm at 5 ⁇ m and, on the other hand, a 4,4-diaryibutadiene compound.
- UV- B rays with wavelengths between 280 and 320 nm, known by the name UV- B, cause erythema and skin burns which can affect the development of natural tanning; this UV-B radiation must therefore be filtered.
- UV-A rays with wavelengths between 320 and 400 nm, which cause browning of the skin, are capable of inducing an alteration of the latter, in particular in the case of skin. sensitive or skin continuously exposed to solar radiation.
- UV-A rays cause in particular a loss of elasticity in the skin and the appearance of wrinkles, leading to premature aging. They promote the triggering of the erythematous reaction or amplify this reaction in certain subjects and can even be the cause of photo-toxic or photo-allergic reactions. It is therefore desirable to also filter UV-A radiation.
- sunscreen compositions intended for photoprotection (UV-A and / or UV-B) of the skin have been proposed to date.
- These sunscreen compositions are quite often in the form of an emulsion of the oil-in-water type (that is to say a cosmetically acceptable support consisting of an aqueous dispersing continuous phase and an oily dispersed discontinuous phase) which contains , at various concentrations, one or more conventional organic filters, lipophilic and / or hydrophilic, capable of selectively absorbing harmful UV radiation, these filters (and their quantities) being selected according to the sun protection factor sought, the factor of sun protection (SPF) expressed mathematically by the ratio of the dose of UV radiation necessary to reach the erythematogenic threshold with the UV filter with the dose of UV radiation necessary to reach the erythematogenic threshold without UV filter.
- SPF factor of sun protection
- the Applicant has discovered, unexpectedly and surprisingly, that the combination, in proportions comprised within well-defined limits, of two sun filters particular and already known per se in the state of the art, made it possible, due to a remarkable synergistic effect, to obtain sunscreen compositions having clearly improved protection indices, and in any case largely superior, to those which can be obtained either with one or the other of the filters used alone.
- new cosmetic compositions for topical use are now proposed, in particular for the photoprotection of the skin and / or the hair, characterized in that they comprise, in a cosmetically acceptable support, at least:
- the present invention also relates to the use of such compositions for the manufacture of cosmetic compositions intended for the protection of the skin and / or the hair against ultraviolet radiation, in particular solar radiation.
- the present invention also relates to the use of a 4,4-dyarylbutadiene compound for the manufacture of cosmetic or dermatological compositions intended for the protection of the skin and / or the hair against ultraviolet radiation, in particular solar radiation comprising at least one organic, insoluble UV filter with a particle size ranging from 10 nm to 5 ⁇ m, with the aim of producing a synergistic effect at the level of the sun protection indices conferred.
- insoluble UV filter within the meaning of the present invention, is meant by any organic or inorganic UV filter having a solubility in water of less than 0.1% by weight and a solubility of less than 1% by weight in most solvents organic such as paraffin oil, benzoates of fatty alcohols and triglycerides of fatty acids, for example Miglyol® 812 sold by the company DYNAMIT NOBEL.
- This solubility defined at 70 ° C as the amount of product in solution in the solvent at equilibrium with an excess of solid in suspension, can easily be evaluated in the laboratory.
- compound 4,4-diar lbutadiene means any molecule comprising at least one chromophore group 4,4-diaryIbutadiene. This can be in the form of a simple compound, an oligomer or a polymer having on the chain grafts containing the chromophore group.
- the insoluble UV filter and the 4,4-diarylbutadiene compound are present in said compositions in a proportion producing a synergistic activity at the level of the sun protection factors conferred.
- the insoluble organic UV filters according to the invention have an average particle size which varies from 10 to 5 ⁇ m and more preferably from 10 nm to 2 ⁇ m and more particularly from 20 nm to 2 ⁇ m.
- the insoluble organic filters according to the invention can be brought into the desired particulate form by any ad-hoc means such as in particular dry grinding or in solvent medium, sieving, atomization, micronization, spraying.
- the insoluble organic filters according to the invention in micronized form can in particular be obtained by a grinding process of an insoluble organic UV filter in the form of particles of coarse size in the presence of an appropriate surfactant making it possible to improve the dispersion. particles thus obtained in cosmetic formulations.
- the grinding apparatus used according to these documents can be a jet, ball, vibration or hammer mill and preferably a high agitation mill or an impact mill and more particularly a rotary ball mill, a vibrating mill, tube mill or rod mill.
