Description of key information

Biodegradation in water, screening tests:  46% in 28 days (EU Method C4-C Carbon Dioxide Evolution Test)

Key value for chemical safety assessment

Additional information

The result from this study is likely to represent biodegradation of ethanol, which is expected to biodegrade rapidly, and consists of 6 of the 9 carbons in the chemical structure. Therefore, 3 -chloropropylsilanetriol is not expected to undergo any significant biodegradation.

This is supported by evidence that within a category of small molecule silicon-dominated organosilicon compounds, without reactive functional groups in the side chain, there is no evidence of any significant biodegradation in ready biodegradation tests (Data gap filling report for ready biodegradability of silicon-dominated substances PFA.151.004.022A).
