I'm currently developing a serum formula. So I would like to ask you about the solution.
Retinyl Acetate .
Retinyl Acetate soluble in
ethanol or organic solvent, try
ethanol as a solvent by Use
Retinyl Acetate 0.1 g in
ethanol 10 g so it doesn't melt at all. So try changing Solvent to
mineral oil 10 g instead, still not melting. So I asked for advice on what to do. Can give solution. The properties of the important substances are not spoiled as well. Thank you.
