Perfume Grade Ethanol is referred to as 95PGF4 Ethanol that is designed to be suitable to use as a perfume base. The reason for this is that this ethanol, unlike regular ethanols, has very low to a neutral odour. Perfume grade alcohol has a flashpoint of 11ºC with a boiling range of 78-83ºC and a specific gravity of 0.8.
The perfume alcohol is 95% and contains 5% water and denaturant so that it cannot be consumed. The F4 solution means that it has an additive that is quite bitter and unpalatable for drinking, but it is designed to work with other fragrances.
