What is Cinnamomum Cassia (Cinnamon) Leaf Oil?

Cinnamomum Cassia Leaf Oil is a volatile essential oil derived through steam distillation of leaves from the Cinnamomum cassia tree, an evergreen species native to southern China and Southeast Asia, distinct from true cinnamon (C. verum). Chemically, it features a complex profile dominated by trans-cinnamaldehyde (up to 80%), alongside eugenol, linalool, and benzyl benzoate, yielding a potent, warm-spicy profile. In cosmetic formulations, it primarily functions within fragrance categories, enhancing sensory appeal in perfumes, colognes, soaps, shampoos, and alcohol-based toners. As a fragrance ingredient, it defines scent character; as a masking agent, it neutralizes off-notes; it also denatures ethanol to render it unfit for consumption while subtly influencing evaporation and feel in sprays.
