Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The EC50 is > 100 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L

Additional information

The growth of the algae was promoted by the test substance isopentyl acetate. Due to fertilization effects, the resulting metabolites of the test item obviously increased the growth of the algal population up to more than 65% at a nominal test concentration of 100 mg/L, compared to the control. Cell numbers increased by more than a factor of 16 within 48 hours. The EC50 is therefore > 100 mg/l.
