Azelaic Acid and Solvent Dilemma
Hello!
So so I am trying to make an Azelaic Acid serum and I’m wondering if Dimethyl Isosorbide would be an appropriate solvent to use? I know ethoxydiglycol is often used but I’m leaning more towards DMI because it’s a bit more cosmetically elegant! I’m also wondering if anyone has any tips and ball park usage range for the DMI in this type of formulation.
Thank you very much!!
