Need help Prevent Fragrance from Smoking in Heat-Activated Hair product
I’m formulating a cosmetic hair product that requires heat activation keratin treatment However, when I add fragrance extract (even at just 1%), the product produces smoke when heat is applied.
I suspect this might be due to the fragrance’s volatility or flash point. Are there specific types of fragrances or solubilizers that can withstand high temperatures without causing smoke ? In the video there is a test of heating a small amount of the perfume extract.

You could try adding a fixative (like triethyl citrate), but I don’t know how well that will work- what temperature will your product be used at? I’m also not sure how much you could reduce the fragrance volatility without impacting perception/scent intensity- that volatility is what helps the fragrance molecules reach our noses’ receptors. Your test looks like a much larger quantity than would be used in real life- if you try your product on some hair extensions can you even see the vapor/smoke?

What are you “heat activating” and what temperature do you need to reach?
