Abstract

Description
Composition, notamment cosmétique, renfermant un steroïde et un filtre UV liposolubleComposition, in particular cosmetic, containing a steroid and a liposoluble UV filter
La présente invention se rapporte à une composition renfermant, dans un milieu physiologiquement acceptable, au moins un steroïde choisi parmi : la DHEA et/ou un précurseur biologique et/ou un dérivé métabolique de celle-ci, caractérisée en ce qu'elle comprend en outre au moins un filtre UV liposoluble. Elle se rapporte également à ses utilisations, et à un procédé de solubilisation du steroïde précité au moyen d'au moins un filtre UV liposoluble.The present invention relates to a composition containing, in a physiologically acceptable medium, at least one steroid chosen from: DHEA and / or a biological precursor and / or a metabolic derivative thereof, characterized in that it comprises in addition to at least one liposoluble UV filter. It also relates to its uses, and to a process for dissolving the aforementioned steroid by means of at least one liposoluble UV filter.
La DHEA, ou déhydroépiandrosterone, est un steroïde naturel produit essentiellement par les glandes corticosurrénales. Elle est connue pour sa capacité à promouvoir la kératinisation de l'épiderme (JP-07 196 467), ou encore dans le traitement des peaux sèches, en raison de son aptitude à augmenter la production endogène et la sécrétion de sébum et à renforcer l'effet barrière de la peau (US-4,496,556). Il a également été décrit dans le brevet US-5,843,932 l'utilisation de la DHEA pour remédier à l'atrophie du derme par inhibition de la perte de collagène et de tissu conjonctif. Il a enfin été proposé d'utiliser le sulfate de DHEA pour traiter différents signes du vieillissement tels que les rides, la perte d'éclat de la peau et le relâchement cutané (EP-0 723 775).DHEA, or dehydroepiandrosterone, is a natural steroid produced mainly by the adrenal cortex. It is known for its ability to promote keratinization of the epidermis (JP-07 196 467), or even in the treatment of dry skin, due to its ability to increase endogenous production and sebum secretion and to strengthen l barrier effect of the skin (US Pat. No. 4,496,556). It has also been described in US Pat. No. 5,843,932 the use of DHEA for remedying atrophy of the dermis by inhibiting the loss of collagen and connective tissue. Finally, it has been proposed to use DHEA sulfate to treat various signs of aging such as wrinkles, loss of radiance of the skin and sagging skin (EP-0 723 775).
On comprend donc l'intérêt qu'il peut y avoir à utiliser la DHEA dans des compositions cosmétiques ou dermatologiques.We therefore understand the advantage that there may be in using DHEA in cosmetic or dermatological compositions.
Or, la DHEA ne se solubilise que difficilement dans les milieux aqueux et hydroalcooliques, ce qui limite sa formulation dans des compositions cosmétiques ou dermatologiques appliquées par voie topique ou orale. Elle a ainsi tendance à recristalliser ou à se dégrader. Il s'ensuit une perte d'efficacité plus ou moins importante de ces compositions, selon le degré de recristallisation et/ou de dégradation, ce qui va à rencontre de l'objectif recherché. En outre, cette recristallisation ou dégradation peut modifier la stabilité globale de ces compositions ainsi que leur aspect, ce qui peut détourner l'utilisateur de celles-ci.However, DHEA dissolves only with difficulty in aqueous and hydroalcoholic media, which limits its formulation in cosmetic or dermatological compositions applied topically or orally. It therefore tends to recrystallize or degrade. This results in a more or less significant loss of effectiveness of these compositions, depending on the degree of recrystallization and / or degradation, which goes against the objective sought. In addition, this recrystallization or degradation can modify the overall stability of these compositions as well as their appearance, which can divert the user from them.
Il subsiste donc le besoin de solubiliser la DHEA, ainsi que ses précurseurs et/ou dérivés posant les mêmes problèmes de recristallisation, dans un solubilisant physiologiquement acceptable.
La Demanderesse a maintenant constaté, de façon étonnante, que ces composés pouvaient être facilement solubilisés dans les filtres UV liposolublesThere therefore remains the need to dissolve DHEA, as well as its precursors and / or derivatives posing the same recrystallization problems, in a physiologically acceptable solubilizer. The Applicant has now surprisingly found that these compounds can be easily dissolved in liposoluble UV filters
La présente invention a donc pour objet une composition renfermant, dans un milieu physiologiquement acceptable, au moins un steroïde choisi parmi la DHEA et/ou un précurseur biologique et/ou un dérivé métabolique de celle-ci, caractérisée en ce qu'elle comprend en outre au moins un filtre UV liposolubleA subject of the present invention is therefore a composition containing, in a physiologically acceptable medium, at least one steroid chosen from DHEA and / or a biological precursor and / or a metabolic derivative thereof, characterized in that it comprises in addition to at least one liposoluble UV filter
Elle a également pour objet un procédé de solubilisation d'au moins un steroïde choisi parmi la DHEA et/ou un précurseur biologique et/ou un dérivé métabolique de celle- ci, comprenant l'étape consistant à mélanger ledit steroïde a au moins un filtre UV liposolubleIt also relates to a process for the solubilization of at least one steroid chosen from DHEA and / or a biological precursor and / or a metabolic derivative thereof, comprising the step consisting in mixing said steroid with at least one filter. Fat-soluble UV
Le mélange peut être effectué à froid, à température ambiante ou à chaud, par exemple à 75°C, généralement sous agitationThe mixing can be carried out cold, at room temperature or hot, for example at 75 ° C., generally with stirring
