Bath Oils and Their Various Uses
Bath oil is any concentrated, hydrophobic liquid containing volatile aroma compounds from plants. They are also known as volatile or ethereal oils, or simply as the "oil of" the plant material from which they were extracted, such as oil of clove. The term essential indicates that the oil carries distinctive scent (essence) of the plant, not that it is an especially important or fundamental substance.
Essential oils do not need to have any specific chemical properties in common, beyond conveying characteristic fragrances. They are not to be confused with essential fatty acids. Bath oils are generally extracted by distillation. Other processes include expression, or solvent extraction. They are used in perfumes and cosmetics, for flavoring food and drink, and for scenting incense and household cleaning products.
