IFRA conformity of natural essential oils/fragrance mixtures
An essential oil is defined as a volatile part of a natural product, which can be obtained by distillation, steam distillation or expression in the case of citrus fruits. Essential oils are derived from various sections of plants. The oil is “essential” in the sense that it carries a distinctive scent, or essence of the plant.
