What composition can I use for a vaginal cream with prasterone (DHEA) 2.5% in Carbomeergel?

I suspect that a vaginal cream is also usable. A good vaginal cream is   This contains propylene glycol, in which prasterone could be soluble like so many other corticosteroids.

Glycerol monostearate 4g LIGHT Liquid Paraffin Wax 14g White Vaseline 15.5 g Cetomacrogol 7.5 g Propylene glycol 10g Water up to 100 g If the cream Is too liquid, you have to increase the Vaseline content. Possibly up to 24.5 g.
