Water Solubility (trimethoxy(2-methylpropyl)silane): 4900 mg/l at 20°C (QSAR)Water Solubility ((2-methylpropyl)silanetriol): very soluble at 20°C (QSAR)
The requirement to test the substance for water solubility is
waived on the basis that it hydrolyses rapidly to
(2-methylpropyl)silanetriol and methanol. The water solubility of both
the registered substance (4900 mg/l) and the silanol hydrolysis product
(1 000 000 mg/l) have been calculated using a validated QSAR.
The silanol is predicted to be very soluble in water; however,
silanetriols may undergo condensation reactions to give siloxane dimers,
oligomers and polymers; this will limit its solubility in practice.
