Ethanol (often denatured) is the primary alcohol used in perfume.
Perfume formulations typically rely on alcohol as a solvent and carrier for fragrance oils. Here's a breakdown:
- Ethanol (Denatured): This is the most common type of alcohol used. "Denatured" means it has additives to make it unsuitable for drinking, which avoids alcohol taxes and regulations associated with consumable alcohol.
- Function: Ethanol serves as a solvent, dissolving the fragrance oils and allowing them to blend properly. Crucially, it evaporates quickly when applied to the skin, releasing the fragrance into the air. The alcohol's volatility is key to a perfume's projection and longevity.
- Why Ethanol?: Ethanol is favored because it's relatively odorless, colorless, and evaporates at a suitable rate. This allows the fragrance to be the prominent scent, without being overshadowed by the solvent itself.
In summary, ethanol, usually in a denatured form, is the primary alcohol used in perfumes to dissolve and carry fragrance oils, facilitating their release upon application.
