Conclusion on classification

Acute aquatic toxicity studies with fish, daphnia and algae all show no toxicity at the limit of water solubility. Long-term studies with daphnia and algae have NOELRs that are > water solubility and > 1 mg/L. Ultimate biodegradation (CO2 evolution) > 60% in 28 days has been demonstrated in an enhanced ready biodegradation study, and bioaccumulation potential is very low. Therefore classification for environmental effects is not warranted.
