Eugenol is an floral volatile scent compound, an allyl chain-substituted Guaiacol.

    Eugenol is a colorless to pale yellow oily liquid, with a pleasant, spicy, clove-like scent. It is slightly soluble in water, soluble in ethanol, acetone, ethyl acetate, ether, chloroform and other organic solvents.

    Eugenol is used as a flavor or aroma ingredient in teas, meats, cakes, perfumes, cosmetics, flavorings, and essential oils. It is the main ingredient for the preparation of essences like clove, carnation, etc.

    Eugenol is also used as a local antiseptic and anaesthetic. It is an ingredient in some insecticides and in some fungicides and weed control products used in agricultural practices in the EU. It is used in hundreds of household products, such as pesticides, pet care, laundry, cleaning, and paper or vehicle products.

    Clove oil is common as an anesthetic for use on aquarium fish as well as on wild fish.

    Eugenol is subject to restrictions on its use in perfumery, as some people may become sensitized to it.
