Additional information

The substance is used as Transported Isolated Intermediate under Strictly Controlled Conditions. Release of substance to the environment is controlled by appropriate technical and managerial means. Procedural controls are in place for transfer, cleaning, maintenance, waste treatment and accidental release. Environmental exposure to the substance is thus minimised. A derivation of PNECs is deemed not necessary.

Conclusion on classification

Adequate chronic toxicity data are not available for all three trophic levels. Of the available toxicity data algae are the most sensitive species, and fish the least. Because the substance is readily biodegradable and the log Pow=1.29, the acute toxicity data for aquatic invertebrates do not trigger classification. The effect concentrations for algae are ErC50(96h)=8.7 mg/L and NOEC(growth rate)=0.071 mg/L. The chronic toxicity data triggers classification as Category Chronic 2. The substance thus meets the criteria for classification as Hazardous to the aquatic environment, Category Chronic 2, according to Regulation (EC) No. 1272/2008, as amended by Regulation (EC) No. 286/2011.
