Description of key information

A GLP OECD 201 study is available.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L

Additional information

The growth rate EC50 for propylene glycol phenyl ether is greater than 100 mg/L in Scenedesmus subspicatus, while the NOEC is12.5 mg/L. Since 42.7% inhibition of the growth rate was observed at the highest tested concentration of 100 mg/L, this concentration will be considered as a conservative estimation of the algal EC50, which indicates that alga was the most sensitive species tested.
