Using heat on powder cosmetics
so I was thinking about this the other day, if you were to grind carnauba wax to a really fine powder, mix it with pigment and then somehow apply a low source of heat would it bond everything together while staying powder or would it just turn I to a brick? Obviously percentage of wax can’t be too high but a 15-20% inclusion. Would that effect the way pigments stick when pressed? Could it be used an efficient binder?
Just curious.

It would certainly be an interesting experiment, but my educated guess is that you’d get a brick.
But - even if by some miracle you didn’t get a brick, your product would still fail as a cosmetic - because you wouldn’t have the other half of the binder’s function. Liquid binders actually serve a dual purpose - their first function is to hold the product together, but their second function is to adhere the powder to the skin. Without that adherence, your customers could have all of the cosmetic powder falling off of their skin in as little as 15 minutes, in my experience.
Powder cosmetics are a delicate balance among a number of attributes, and a number of very talented chemists worldwide have been working on formulations for years and even decades. New/innovative ideas are hard to come by.

Yeah I’ve noticed that! I’ve been experimenting with different levels is oil binding agents verses different particle sizes. From what I can tell the ultra fine particle sizes have to have a higher oil content. Thanks for letting me know your thoughts!
