Description of key information

substance: 9200 mg/l
silanol hydrolysis product: 1000000 mg/l
methanol: miscible at 20°C (measured)

Key value for chemical safety assessment

Additional information

The substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours). The hydrolysis half-life of the substance is predicted to be 4.6 h.

Predicted water solubilities of the substance and hydrolysis product are 9200 mg/l and 1000000 mg/l respectively. These were predicted using an appropriate QSAR and so are considered reliable. Methanol is miscible in water at 20°C based on experimental data (OECD, 2004).
