Description of key information

Water Solubility (triacetoxyethylsilane): not relevant
Water Solubility (ethylsilanetriol): miscible at 20°C (QSAR)

Key value for chemical safety assessment

Additional information

The requirement to test the substance for water solubility is waived on the basis that it hydrolyses very rapidly to ethylsilanetriol and acetic acid. The water solubility of the silanol hydrolysis product has been calculated using a validated QSAR. The hydrolysis product was predicted to be miscible at 20°C. In a secondary source to which no reliability can be assigned, the substance was reported as miscible.

Acetic acid reported to be miscible with water in a secondary source which has been subject to peer review (Stecher et al 1968)
