(E)-Isoeugenol is crystalline while compound with spice clove type odor. The melting point of E-isoeugenol is 33°C. E-Isoeugenol has been shown to cause contact and allergic dermatitis in humans. Positive skin patch tests in numerous individuals have confirmed the sensitizing ability of isoeugenol.
