Key value for chemical safety assessment

Additional information

A reasonable estimate of BCF can be obtained by estimation from log Kow using the method in the Technical Guidance Document on Risk Assessment (EC 2003, Part III. Chapter 4, Section, Page 31 - 33). The estimated value is 86 l/kg-wwt.

3 -(Triethoxysilyl)propanethiol hydrolyses (half-life approximately 18 h, predicted) in contact with water to 3 -(trihydroxysilyl)propanethiol and ethanol, both of which have low log Kow values (<3), and thus have low potential for bioaccumulation.
