While we’re discussing sweet smelling things, maybe I should mention that ethyl alcohol is also used in the production of essential oils for aromatherapy. Ethanol extraction is a type of solvent extraction used to harvest fragrant compounds directly from dry plant materials, as well as impure vegetable oils. Vanilla extract is often produced using a polar solvent such as ethanol. The polarity of ethanol allows extraction of the volatile aromatics while leaving behind the non-polar plant waxes. The ethanol is then evaporated to leave behind ‘absolute vanilla’ (but in most cases as much as 5% ethanol remains).
One of the most interesting uses for ethanol is marine taxidermy – here the stuff is used as an transparent embalming fluid.
Marine biologists who adventure deep inside the ichthyarchy (the domain of fishes) often try to capture rare photosensitive critters that don’t keep well in fresh water, or brine, and don’t display well in glycerin. The solution is pure ethanol. This clear and colorless alcohol preserves deep water marine specimens and keeps them looking just as fresh as they did when they were first caught.
