Conclusion on classification

 

Official classification regarding environmental hazards

Aquatic compartment

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not officially classified.

In accordance with Regulation (EC) 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 data, the substance is not to be classified as 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 value is > 1 mg/L.

Chronic data are available for Daphnia (21 -d EC10 = 16 mg/L) and algae (72-h ErC10 = 26 mg/L); therefore, classification is based on the available chronic

(Daphnia, algae) and acute toxicity (fish; 96 -h LC50 > 10000 mg/L) data.

- Chronic toxicity data: The substance is rapidly degradable, and the available chronic effect values (EC10) are 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 is the trophic level not covered by chronic data. Therefore, classification is also assessed based on the respective acute effect data. The LC50 is greater than 100 mg/L, the substance is rapidly degradable and the log Pow is < 4. Therefore, the substance is not to be classified as chronically hazardous.
