Common Name | Thymol |

Description | Thymol is a phenol obtained from thyme oil or other volatile oils. It is used as a stabilizer in pharmaceutic preparations. It has been used for its antiseptic, antibacterial, and antifungal actions, and was formerly used as a vermifuge. Thymol is a monoterpene phenol derivative of cymene, C10H13OH, isomeric with carvacrol, found in oil of thyme, and extracted as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. It is also called "hydroxy cymene". In a 1994 report released by five top cigarette companies, thymol is one of the 599 additives to cigarettes. Its use or purpose, however, is unknown, like most cigarette additives. |
