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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
