Isoeugenol, with the CAS number 97-54-1, is a synthetic compound that is commonly used in perfumery for its sweet, spicy, and clove-like aroma. It is often found in floral and oriental fragrance compositions, where it can enhance the depth and complexity of the scent profile. Isoeugenol is typically used in lower concentrations due to its potency and potential allergenic properties. In terms of safety and regulatory considerations, it is important to note that isoeugenol is classified as a potential skin sensitizer, and its use is subject to restrictions in certain applications. The International Fragrance Association (IFRA) has established guidelines for its usage in cosmetic products, which perfumers must adhere to in order to ensure consumer safety. As a versatile ingredient, isoeugenol can be utilized in various fragrance types, but careful formulation is necessary to balance its strong character with other components in a blend. — AI-generated summary, 2026-09-02.

Perfume and Flavor Chemicals, page 560.
Pale yellowish or almost colorless, slightly viscous liquid.
Practically insoluble in water, soluble in alcohol, oils and propylene glycol, soluble with turbidity in mineral oil, insoluble in glycerin.
Mild and sweet, deep-floral, very tenacious odor with great warmth and resemblance to Carnation, Sweet Williams or Wallflower. Poorer grades often show variable degree of dry-woody Eugenol-spiciness.
Warm, sweet, slightly burning taste with a floral note and spiciness varying with the quality of the material.
Extensively used in perfume compositions, mainly as a base for Carnation, but also in general as a sweet floralizing agent of excellent tenacity. It is a classical ingredient in 'l’Origan' type fragrances and may give the highly desirable warm background and powdery note in a Lilac base.
Used sparingly in many types of flavor, e.g. imitation Raspberry, Peach, Nutmeg (Mace), Cinnamon, Apricot, as well as in fruit complexes, Nut, Mint, Spice bases and in Clove flavors.
Produced from Eugenol by isomerization with alkali under heat. Potassium hydroxide is usually applied.
