Description of key information

Additional information

Due to the chemical structure of Fatty acids, C18-unsaturated, dimers, hydrogenated (CAS No. 68937-90-6) and the low water solubility (< 0.52 mg/L, limit of detection) hydrolysis does not contribute to abiotic degradation in the aquatic environment.

Photodegradation of Fatty acids, C18-unsaturated, dimers, hydrogenated (CAS No. 68937-90-6) in air is not a relevant degradation pathway as the vapour pressure under ambient conditions is negligible.
