IsoEugenol: A Spicy, Warm, and Floral Aroma Ingredient
IsoEugenol is a naturally occurring and synthetically produced aromatic compound widely used in perfumery, cosmetics, and flavor industries. It has a warm, spicy, clove-like scent with soft floral and woody undertones, making it a key ingredient in many oriental, floral, and spicy fragrance compositions. IsoEugenol is derived from clove oil, nutmeg, and cinnamon and is often used as a precursor for synthesizing vanillin (a major component of vanilla fragrance).
