Description of key information

Stability: The test item hydrolyses very fast at pH 1.2 (37 ºC), 4 (25 ºC), 7 (25 ºC) and 9 (25 ºC) being the half-lives 3.46, 4.62, 19.8 and 9.5 min respectively. The main hydrolysis product is ethyl lactate, but at pH 1.2 and 9.0 ethanol and lactic acid also appear. No other products were identified above 10% of the VL3 amount at the end of the hydrolysis. The presence of silane-dimer, trimer oligomer chains were seen in the beginning of the reactions. Since the NMR technique used is sensitive only for dissolved substances no quantitative information could be provided about these longer chain products, because they left the solution in form of colloids or gel-like white precipitate.

Biodegradation: Under aerobic and aquatic conditions, the test substance is ready biodegradable.

Bioaccumulation: The substance has a low potential for bioaccumulation.

Transport and distribution: The substance can be expected to have a low potential for adsorption.
