Additional information

Farnesene is essentially insoluble in water. At the limit of solubility it is not expected to cause effects on aquatic organisms, following acute or chronic exposure. It does not meet the criteria to be considered readily biodegradable but experimental data shows a clear potential to degrade in the aquatic environment.

Conclusion on classification

Farnesene is insoluble in water, has a log Kow > 4 and is not readily biodegradable. It does however show a clear potential to degrade in the environment. Chronic exposure of aquatic species to saturated concentrations of a structural analogue farnesane did not result in toxicity at the limit of solubility.

Farnesene is not classified for aquatic toxicity based on no toxicity following acute exposure and no evidence of chronic effects in aquatic species at the limit of water solubility.
