Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
