Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Biodegradation in water: screening tests: 0% in 28 days (OECD TG 310, Ready biodegradability - CO2 in Sealed Vessels (headspace test)). The silanol hydrolysis products, 3-(trihydroxysilyl)propyl methacrylate and trimethylsilanol, are not expected to biodegrade to any significant extent.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A reliable ready biodegradation study, conducted according to OECD Test Guideline 310, is available, and gives a biodegradation result of 0% in 28 days based on CO2 evolution.
3-[3,3,3-Trimethyl-1,1-bis[(trimethylsilyl)oxy]disiloxanyl]propyl methacrylate hydrolyses slowly (half-life approximately 26 days at pH 7 and 25°C) to 3-(trihydroxysilyl)propyl methacrylate and trimethylsilanol. The silanol hydrolysis products are not expected to biodegrade to any significant extent and the experimental result confirms this expectation.
