Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

* the highest attainable test substance concentration in the test conditions

According to the tonnage band of the registered substance, only acute studies on aquatic invertebrates and algae are required.

For the aquatic invertebrates, a waiving is proposed for the acute study because a chronic study is available on the registered substance. This chronic study was performed according to OECD Guideline 211 with GLP certificate.The lowest 21d-EC10 value, based on intrinsic rate of population increase, was determined at 0.121 mg/L, based on time weighted mean measured concentrations.

For the algae, a study was performed on the registered substance according to the OECD guideline 201 with GLP certificate. The 72h-ErC50 value was above 0.715 mg/L, the highest attainable test substance concentration in the test conditions, and the 72h-ErC10 was 0.596 mg/L, based on geometric mean measured concentrations.
