Volatile Oil vs. Fixed Oil: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 13, 2024
Volatile oils evaporate at room temperature and are aromatic (e.g., essential oils), whereas fixed oils don't evaporate, are non-volatile, and leave a stain (e.g., vegetable oils).

Key Differences

Volatile oils are known for their ability to evaporate at room temperature. These oils, often used for their fragrance, contrast with fixed oils, which are heavier and do not evaporate under normal conditions.
