Additional information

For azelaic acid (CAS 123 -99 -9) one study on algae is available. In this GLP-study which was conducted according to OECD 201 with Pseudokirchnerella subcapitata under static conditions an EC50 of > 67 mg/L (meas. TWA) for growth rate was determined after 72 h of exposure (Tobor-Kaplon, 2010a). The NOEC for growth rate was reported to be 7.0 mg/L. This study was used as key study.
