I am wondering if there was any significant cosmetic, health or product functionality difference between isopropyl and SD alcohol. I am currently formulating an anhydrous airbrush makeup using a silicone acrylate film former dispersed in a volatile silicone. Aproximately 75% of the fluidic portion is alcohol. I have been using 99% Isopropyl because I have always considered it healthier for the skin, though I am not sure what evidence I am basing this off of. I suppose I was always skeptical of what the denaturing agents were used and if they would be compatible or leave a residue.
I need a carrier that is very fast drying, but I am considering switching to SD alcohol because it is much cheaper.
Any input would be helpful, thanks!
