volatile oil
Noun: A concentrated, hydrophobic liquid containing aromatic compounds extracted from plants. It is characterized by evaporating readily at normal temperatures, carrying the distinctive scent (odor) or taste (flavor) of its source plant. These oils are primarily used in perfumes, aromatherapy, and as flavoring agents in food and drink.
The term "volatile oil" is used to describe the essential, aromatic extract of a plant. It emphasizes the oil's physical property of volatility (easily evaporating) and its origin. * Lavender volatile oil is commonly used in perfumery and for its calming effects. * The volatile oil from peppermint leaves gives the candy its strong, cooling flavor. * Many volatile oils are extracted through a process called steam distillation.
- In a scientific or botanical context, "volatile oil" is often synonymous with "essential oil," though "essential oil" is the more common commercial and holistic wellness term.
- The phrase can be used attributively (as a noun modifier) in technical descriptions.
- The plant's volatile oil content determines its potency as a flavoring.
- Essential Oil: A nearly identical term more frequently used in commerce, aromatherapy, and everyday language. The distinction is minor; "volatile oil" may be preferred in some chemical or pharmacological texts to highlight the substance's physical property.
- Ethereal Oil: An older, less common synonym for volatile oil.
- Essential Oil
- Ethereal Oil (archaic/technical)
- The term is specific to plant-derived aromatic extracts. It is not used for fixed oils (like olive or coconut oil, which do not evaporate readily) or for petroleum-based oils.
- "Volatile" in this context refers to high vapor pressure and evaporation, not to instability or explosiveness, though some volatile oils are flammable.
- an oil having the odor or flavor of the plant from which it comes; used in perfume and flavorings
