Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

An activated sludge inhibition test was conducted with tripropylene glycol n-butyl ether highers (DOWANOL TPnB-Highers) following OECD 209. The resulting EC50 vlaue was determined to be greater than 1,000 mg/L, the highest concentration tested.
