How would you perform the following magistal preparation? Oestradiolbenzoaat 1 gr minoxidil 2 gr Propylene glycol 10 gr Water 20 GR Spiritus 94 ° AD 100 g

Without the Oestradiolbenzoaat I see no problem considering we have to do with the classic formula for Minoxidil Lotio. The question is, of course, how Oestradiolenzoaat responds. Therefore, I would start with Oestradiolbenzoaat and minoxidil to dissolve in the mixture spiritus-propylene glycol. I would add Water very slowly under constant control to the formation of a cloudy. If a cloudy one would add 2 ml of propylene glycol, since this is a good solvent for both minoxidil and Oestradiolbenzoaat. And then continue further with the addition of water AD 100 g.
