Description of key information
Potassium methanolate has a half-life of approx. 19 days via indirect photolysis.
Key value for chemical safety assessment
- Half-life in air:
- 19 d
Additional information
No experimental studies are available investigating the phototransformation of potassium methanolate in air. This endpoint is no data requirement according to Regulation (EC) No 1907/2006.Nevertheless, the hydroxyl-radical mediated phototransformation in air was calculated for potassium methanolate using the AOPWIN program (version 1.91). The half-life calculated for indirect photolysis is approx. 19 days (Study director, 2005).
