biodegradation in water: sediment simulation testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

Based on the readily biodegradability status of the substance, the CSA demonstrates safe use. Therefore half-life data from simulation tests is not required to further refine the exposure assessment. 

Key value for chemical safety assessment

Additional information

In accordance with REACH Annex IX column 2, the study need not be conducted as the test substance is readily biodegradable. In these circumstances, simulation tests will provide little additional information as rapid mineralisation in the environment is already assumed.
