What is better in perfume making vodka or isopropyl alcohol?

Neither vodka nor isopropyl alcohol are suitable for use in perfume making.

Perfume is typically made with perfumer's alcohol (also known as ethyl alcohol or ethanol), which is a high-quality, purified form of alcohol that is specifically intended for use in perfumery.

Perfumer's alcohol is often denatured, which means that it has been treated to make it unpalatable for drinking, but it is still safe to use for cosmetic purposes. Perfumer's alcohol evaporates quickly, allowing the fragrance oils to remain on the skin.

Vodka and isopropyl alcohol are not suitable for use in perfume making because they can leave behind an unpleasant odor and may not evaporate evenly, which can affect the scent of the perfume.
