Key value for chemical safety assessment

Additional information

This study is waived for Distilled tall oil, magnesium salt. However, supporting data are read across from the two components of the substance. A study is available for rosin which determined a 3-hour EC50 of >10000 mg/L (Harlan 2010) and a 3-hour EC50 of >1000 mg/L is available for Fatty acids C18-(unsaturated) lithium salts (Harlan 2010).
