Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not classified as hazardous to the environment.

According to Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not classified as hazardous to the environment.

 

Self-classification

Aquatic compartment

Following GHS, the substance is not to be classified as acutely or chronically hazardous to the aquatic environment.

Rationale:

The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect values are greater than 1 mg/L.

Chronic data are available only for algae. Therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is rapidly degradable and the ErC10 is greater than 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data: Fish and Daphnia are the trophic levels not covered by chronic data. Therefore classification is based on the respective acute effect data. The lowest LC/EC50 is 45 mg/L, the substance is rapidly degradable and the log Pow is < 4. Therefore the substance is not to be classified as chronically hazardous.

 

The result of the marine biodegradation studies according to OECD 306 may be considered in case of uses in the marine environment.
