Description of key information

No toxic effects to aquatic invertebrates up to the limit of water solubility (< 0.006 mg/L).

Key value for chemical safety assessment

Additional information

The short-term toxicity offatty acids, C5-9 tetraesters with pentaerythritol (CAS 67762-53-2)to aquatic invertebrates was investigated in a GLP study according to OECD 202 usingDaphnia magnaas test organism under static conditions (Migchielsen, 2012). . The WAFs were prepared by adding the appropriate amount of test substance with subsequent stirring and sampling of the aqueous portions A nominal test concentration of 100 mg/L, corresponding to a measured concentration of 1.3 mg/L, was tested. No immobilisation was observed in the treatment throughout the test period of 48 h. Hence, the 48 h-EL50 is determined to be > 100 mg/L based on the nominal test concentration and > 1.3 mg/L based on the measured concentration. It can therefore be concluded thatthe test substancewill not exhibit short-term effects to aquatic invertebrates up to the limit of water solubility. As it can be seen in the data matrix of the category justification in section 13 and the overall summary, all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results,i.e. no toxic effects to aquatic invertebrates or other aquatic organisms were observed up to the limit of water solubility.
