Which alcohol best to mixing in fragrance for perfume spray?

The best alcohol for mixing in fragrance for perfume spray is typically ethanol, specifically perfumer's alcohol or grain alcohol. These types of alcohol are preferred due to their purity, neutrality, and ability to dissolve essential oils and fragrance compounds effectively. They also evaporate quickly, leaving behind the scent without a heavy residue. Isopropyl alcohol can be used, but it may have a stronger scent that could interfere with the fragrance.
