Description of key information

“Hydrocarbons, C14-C20, aliphatics (≤2% aromatics)” were found to be readily biodegradable (biodegradation > 60% ThOD) in an OECD 306 ready biodegradability test. Taking into account that all those substances have been found biodegradable in seawater 306 test, this is taking over all screening tests results and lead to the conclusion that all the substances belonging to this category with the same properties and are therefore considered readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable
