Definitions
- the present invention relates to a composition containing, in a physiologically acceptable medium, at least one steroid chosen from: DHEA and a metabolic or chemical derivative thereof, characterized in that it also comprises dipropylene glycol.
- DHEA dehydroepiandrosterone
- JP-0.7 196 467 keratinization of the epidermis
- barrier effect of the skin US Pat. No. 4,496,556
- DHEA to remedy atrophy of the dermis by inhibiting the loss of collagen and connective tissue has also been described in US Pat. No. 5,843,932. It has finally 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-0723 775).
- these steroids only dissolve with difficulty in aqueous and hydroalcoholic media, which limits their formulation in cosmetic or dermatological compositions. They therefore tend to recrystallize.
- the formation of poorly controlled size results in poor bioavailability of DHEA or its derivatives in the skin. This results in a more or less significant loss of effectiveness of the compositions containing them, depending on the degree of recrystallization, which goes against the objective sought.
- this recrystallization can modify the overall stability of these compositions as well as their appearance, which can divert the user from them.
- solubilization in Guerbet alcohols of the most polar derivatives of DHEA does not always lead to satisfactory results in emulsion.
- these derivatives have a high capacity for so-called Ostwald ripening which leads to their rapid recrystallization in emulsion, by transfer of these derivatives from the fatty phase containing them to the aqueous phase of the emulsion.
- a subject of the present invention is therefore a composition containing, in a physiologically acceptable medium, at least one steroid chosen from: DHEA and a metabolic or chemical derivative thereof, characterized in that it further comprises dipropylene glycol.
- It also relates to a process for the solubilization of at least one steroid chosen from: DHEA and / or a metabolic or chemical derivative thereof, comprising the step consisting in mixing said steroid with dipropylene glycol.
