DRF alcohol is used in perfumes to dilute and merge essential oils and aromas, and also to help the fragrance last longer on the skin and diffuse.
Alcohol (also called ethanol) is a colourless liquid derived from sugar. It is very volatile and disappears almost instantly when applied, leaving a fresh sensation on the skin. It has been used since the 14th century in perfumes. Before that, fragrance materials were diluted in carrier oils.
As it is very dangerous for health to drink alcohol in pure, high concentration and also because its trade is highly taxed, alcohol must be denatured and therefore made unfit for consumption when used in cosmetics. The ethanol molecule is not changed but substances are added to make it undrinkable.
This alcohol is made out of beets in Europe. A super-bitter flavouring ingredient is added - it is safe for the skin but you will regret it if you try to drink it!
