Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1, the substance is not officially classified.

In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.2, the substance is not officially classified.

 

Self-classification

Aquatic compartment

Following GHS, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available acute and chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.

 

Rationale:

The substance is not classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is >> 1 mg/L (Daphnia magna, EU Method C.2, nominal, not pH-adjusted, BASF AG, 1988, rep.no.: 1/0002/2/88-0002/88).

Chronic data are available only for algae (read-across to CAS 109-01-3); therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is not rapidly degradable and the ErC10 is greater than 1 mg/L (Read-Across to CAS 109-01-3, OECD 201, nominal, analytically verified, pH-adjusted, BASF SE, 2013, rep. no.: 110907AG). According to the criteria outlined in Table 4.1.0(b) (i) (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. Daphnia represent the most sensitive trophic level. The EC50 is greater than 100 mg/L. The substance is not rapidly degradable (see IUCLID Ch. 5.2.1), the log Kow < 4 (log Kow = -0.10, estimated, BASF SE, 2018) and the estimated BCF < 500 (max. BCF = 10 L/kg, see IUCLID Ch. 5.3.1). According to the criteria outlined in Table 4.1.0 (b) (iii) (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.

- Conclusion:

Based on the available acute and chronic toxicity data, the substance is not chronically hazardous to the aquatic environment.
