Question

Essential oils are those which are mainly

• A. Used in soap manufacture
• B. Used in perfumes
• C. Essential for plants
• D. Essential for human kind

Answer 1

The correct option is B Used in perfumes

An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils, ethereal oils or simply as the oil of the plant from which they were extracted, such as oil of clove. An oil is "essential" in the sense that it contains the "essence of" the plant's fragrance, the characteristic fragrance of the plant from which it is derived.

Essential oils do not form a distinctive category for any medical, pharmacological, or culinary purpose. They are not essential for health. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression or solvent extraction. They are used in perfumes, cosmetics and other products, for flavouring food and drink, and for adding scents to incense and household cleaning products.

Thus, the correct answer is option B.
