Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions on Classification:

In the absence of adequate chronic aquatic toxicity information from all three trophic levels, the classification was based on the lowest of the short-term aquatic toxicity values from the three trophic levels (48-h EC50 = 0.81 mg/L in daphnids). Although the substance was not shown to be readily biodegradable (70% degradation in 28 days, exceeding the threshold of 60% degradation but failing the 10-day window), the substance exhibited substantial mineralisation and rapid degradation, and therefore is not considered to be persistent in the environment. The experimentally-determined bioconcentration factor (BCF = 92 L/kg ww) is below the threshold for classification as a chronic aquatic hazard (BCF ≥ 500). Therefore, the substance was assigned a classification of Category Acute 1 for hazards to the aquatic environment, with an M-factor of 1. The substance was not assigned a chronic classification for hazards to the aquatic environment.
