• Solvent types[edit] ประเภทตัวทำละลาย
Perfume oils are often diluted with a solvent, though this is not always the case, and its necessity is disputed. By far the most common solvent for perfume oil dilution is an alcohol solution typically a mixture of ethanol and water or a rectified spirit. Perfume oil can also be diluted by means of neutral-smelling oils such as fractionated coconut oil, or liquid waxes such as jojoba oil.
