Thanks Bob. I’ve used %volatile substance on inorganic materials to determined hydration/water of constitution. I guess my concern here is that many of these organics have vapor pressures much higher than inorganics. This is obviously quite dependent on the particular formula, but can you comment on how accurate this is in your experience with cosmetics?

@Belassi. Thanks for your reply. Good point, that does seem like a better ticket for at home. However, I am actually going to be moving into a lab space and I am looking to do professional-caliber research (I am a chemical engineer). With that in mind, what do you do as professional cosmetic chemist? I was imagining needing two hotplates, two mixers, and possibly a homogenizer. After your comment, it sounds like I’d only need one mixer. Is that right?

Extra credit question: how much of the time are cosmetic chemists working in a fume hood?
