Additional information

Conclusion on classification

In the CLP regulation the identification of acute (short-term) and long-term hazards is based on the aquatic toxicity of the substance, although this shall be modified by taking account of further information on the degradation and bioaccumulation behaviour, if appropriate.

The substance does not meet the criteria for classification under the CLP regulations for hazardous to the environment based on acute fish, daphnia and algal studies, which gave EC/LC50 values of 14.66 mg/L in fish, 17.48 mg/L in Daphnia and 2.4 mg/L in algae. The substance does not meet the classification criteria for Chronic toxicity because it is readily biodegradable and has a log Kow of ≤ 4 (log Kow = 3.7).
