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 REACH Annex I indicates that it is not necessary to conduct the soil simulation test.

Simulation test (soil) is not considered necessary because:

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

           The substance hydrolyses rapidly and the silanol hydrolysis product has a low log Kowvalue and, therefore, exposure of the soil compartment is expected to be low. 

  • The risk characterisation ratios (RCR) for the terrestrial compartment, based on the assumption that the silanol hydrolysis product is not biodegradable, are <1.
