Description of key information
The study need not to be conducted as the substance has a low potential for bioaccumulation (log Kow < 3) and is readily biodegradable.
The calculated Koc for isovaleric acid is 4.022 (GUBDH, 2012).
Key value for chemical safety assessment
- Koc at 20 °C:
- 4.022
Additional information
In accordance with column 2 of REACH Annex IX Nr 9.3.3, the study does not need to be conducted as the substance has a low potential for adsorption (log Kow < 3, see Sect. 4.7) and is readily biodegradable (see Sect. 5.2.1).
As additional information, the Koc of isovaleric acid was estimated to be 4.022 (log Koc = 0.6045) using the Program US EPA EPI Suite v4.10 (GUBDH, 2012). The low Koc indicates high mobility in soil.
[LogKoc: 0.6045]
