Description of key information

Not applicable.

Key value for chemical safety assessment

Additional information

The performance of tests for biodegradation in soil is scientifically unjustified.

REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.2.1.3, Col. 2, states as follows:

“9.2.1.3: The study need not to be conducted:

- if the substance is readily biodegradable, or

- if direct and indirect exposure of soil is unlikely. ”

Direct and indirect exposure of the test item to soil is unlikely. It can be assumed that upon contact with soil and organic matter, the test item undergoes rapid degradation (hydrolysis) resulting in the formation of respective degradation products. Furthermore, the test item is not soluble in water and was considered to be inherently biodegradable. Therefore, simulation testing for biodegradation in soil was considered not scientifically justified.
