Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

With high probability not harmful to aquatic algae. 
EC50 (72h) > 100 mg/L and EC10 (72h) = 3.74 mg/L based on nominal rates for growth rate of Desmodesmus subspicatus (OECD 201)

Key value for chemical safety assessment

Additional information

In a GLP guideline study following OECD 201 green algae (Desmodesmus subspicatus) were exposed for 72 hours to

Fatty acids, C16 -18 and C18 -unsatd., Me esters, epoxidized, reaction products with ethylene glycol [BASF SE, 2013]. Based on the multicomponent composition that is only partially soluble the aquatic toxicity on algae was investigated by using water accommodated fractions (WAF) with a maximum loading of 100 mg/L (measured) test item. The 72-h EC50 for growth rate inhibition is determined to be >100 mg/L based on nominal loading rates (EC10 (72h) = 3.74 mg/L).
