Transformation products:
yes
Remarks:
Degradation is principally expected via abiotic transformation (aqueous). The transformation products expected in the environment are those identified in the abiotic degradation study (IUCLID 5.1.2), on which environmental hazard assessment is based.

Description of key information

Key value for chemical safety assessment

Additional information

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