Description of key information
Key value for chemical safety assessment
Additional information
No information is available for phototransformation in water.
This is not expected to be a significant removal process for trimethoxy(vinyl)silane (CAS 2768-02-7; EC No. 220-449-8) or vinylsilanetriol (CAS 143-48-6).
Experiments carried out for dimethylsilanediol (CAS 1066-42-8, EC No. 213-915-7) indicate that water soluble small molecule silanols will undergo aqueous photolytic oxidative demethylation with tropospheric ultraviolet radiation in the presence of suitable chromophores, such as nitrogen oxides, to give silicic acid and carbon dioxide (Buch et al 1984).
Whilst such degradation is possible for vinylsilanetriol, it is not taken into account in the exposure assessment.
