Description of key information

Bioaccumulation: aquatic/sediment: Low potential for bioaccumulation

Key value for chemical safety assessment

Additional information

The substance hydrolyses rapidly to HCl and ethylsilanetriol. Ethylsilanetriol has a low log Kow value and thus has low potential for bioaccumulation, therefore in accordance with Column 2 of REACH Annex IX, there is no need to conduct the bioaccumulation in aquatic species study.
