What it is
This is the essential oil distilled from the leaves of the clove tree, Eugenia caryophyllus (also called Syzygium aromaticum), and is rich in eugenol. In cosmetics it is used mainly as a natural fragrance and to give a warm, spicy clove aroma. Its high eugenol content also gives it antioxidant character, but in sunscreens it is present as an aromatic ingredient rather than a functional active.
