Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Three acute endpoints for three different trophic levels are available. The lowest ErC50 is found for algae and is 0.47 mg/L. Two chronic endpoints - for algae and Daphnia are available. The most sensitive species is the algae. The ErC10 was determined to be 0.052 mg/L. A long-term study with Daphnia magna showed that invertebrates are less sensitive than algae (no toxic effects up to and including the highest tested concentration of 10 mg/L WAf (5.4 mg/L mean measured)).


The substance is not readily biodegradability and has a log Kow of 3.3.


 


Acute classification:


The lowest acute endpoint for algae is between 0.1 and 1 mg/L and leads to classification as short-term hazard in Acute Category 1 with an M-factor of 1.


 


Chronic classification:


The substance is not readily biodegradable and the chronic ErC10 for algae is between 0.01 and 0.1 mg/L. This would lead to a long-term hazard classification as Chronic Category 1 with an M-factor of 1.


Because not all chronic endpoints are available, chronic classification is also based on acute data: with an ErC50 of 0.47 mg/L and the substance being not readily biodegradable, but having a log Kow < 4 the substance would also be classified as Chronic Category 1.
