Additional information
Conclusion on classification
The three aquatic short-term toxicity tests on fish, invertebrates and algae were carried out between 1997 and 2014. The results were:
Fish 96h-LC50 = 32.3 mg/L
Daphnia 48h-EC50 = 28 mg/L
Algae 72h-ErC50 = 0.24 mg/L
Three chronic results were obtained on fish, invertebrates and algae:
Fish 35d-NOEC = 0.88 mg/L
Daphnia 21d-EC10 = 3.7 mg/L
Algae 72h-ErC10 = 0.21 mg/L.
Classification and labelling according to UN-GHS and CLP is driven by the algae study, combined with ready biodegradability:
H400: Very toxic to aquatic life
H412: Harmful to aquatic life with long lasting effects
