Description of key information
The adsorption coefficient (Koc) of bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine is determined to be > 4.27E+05, with a Log Koc > 5.63 (Harlan Laboratories, 2012).
Key value for chemical safety assessment
- Koc at 20 °C:
- 427 000
Additional information
Key study:
In a study conducted to OECD 121 (conducted to GLP), the adsorption coefficient (Koc) of bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine is > 4.27E+05, with a Log Koc > 5.63.
This value indicates that bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine will be environmentally immobile (Harlan Laboratories, 2012).
Supporting study:
Using The Estimation Programs Interface (EPI) SuiteTMdeveloped by the US Environmental Protection Agency's Office of Pollution Prevention and Toxics and Syracuse Research Corporation (SRC), the log Koc of bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine is determined as 6.867 (KOCWIN, 2010).
[LogKoc: 5.63]
