Description of key information

Key value for chemical safety assessment

Additional information

Testing is waived on the basis that the chemical safety assessment according to Annex I indicates that it is not necessary to conduct the soil simulation test.

The soil simulation test is not considered necessary because:

·       The substance is used under highly controlled conditions and, therefore, exposure of the terrestrial environment is low.

·       The substance has a low Kow(< 3) and, therefore, a low potential for adsorption to soil.

·       The RCRs for the terrestrial compartment, based on the assumption that the silanol hydrolysis product is not biodegradable, are <1.
