1-Decanol is a straight chain fatty alcohol with ten carbon atoms and the molecular formula C10H21OH. It is a colorless viscous liquid that is insoluble in water and has a strong odor.[2] The interfacial tension against water at 20 °C is 8.97 mN/m.


Decanol is used in the manufacture of plasticizers, lubricants, surfactants and solvents.


Decanol causes a high irritability to skin and eyes, when splashed into the eyes it can cause permanent damage. Inhalation and ingestion can be harmful; it can also function as a narcotic. It is harmful in the environment.[3]
