Question

Which of the following is not an essential oil?

• A. Clove oil
• B. Eucalyptus oil
• C. Sandalwood oil
• D. Groundnut oil

Answer 1

The correct option is D Groundnut oil

An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils.

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, soaps and other products, for flavouring food and drink and for adding scents to incense and household cleaning products. Eucalyptus oil, rose oil, lavender oil, clove oil and sandalwood oils are examples of essential oils. Groundnut is an example of non-essential oils which does not have aroma and cannot be used in perfumes and cosmetics.

Thus, the correct answer is option D.
