Farnesene is a liquid at standard temperature and pressure. It is of low viscosity (KV 2.15 mm2/s at 20 °C), insoluble in water (< 100 μg/L with a QSAR predicted value of 11μg/L) and has a partition coefficient (log10Pow) of >6.5. The freezing point is <-20°C, it boils at > 145°C, has a flash point of 116°C and the auto-ignition temperature is 237°C. The density of farnesene is 0.83 g/L at 15°C. It has a vapour pressure of 34 Pa at 25°C and a QSAR predicted Henry's Law Constant of 2.27E+005 Pa-M3/mole,
