Yes, if it is the fluid mass it would be much easier to get a stronger throw... AKA work with fragrance of more concentrate..
I can't seem to find any clear information. Only from the candle stores who want to sell their own FO's and FO's differs a LOT.
Yes, different dilutions.. Used to be Diethyl Phthalate and in some cases still is. Now probably IPM, DOA or something else.. I'm also curious to hear if anyone have done any testing with different solvents in fragrances? If they enhance throw or not?
