Key value for chemical safety assessment

Additional information

Testing is waived on the basis that the substance is readily biodegradable. The substance hydrolyses rapidly (t1/2 3 min at 20 - 25°C) to methanol and (poly)silicic acid. Methanol is readily biodegradable. (Poly)silicic acid is inorganic and so is not biodegradable; it is the water soluble form of inorganic silicon and will enter the natural biogeochemical cycle for silicon.
