Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

There is no data in Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2 for the substance available yet.

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is not to be classified as dangerous for the environment.

Rationale:

- The acute toxicity to aquatic organisms (LC/EC50) is > 100 mg/L in freshwater.

- The substance is not readily biodegradable (freshwater), the log Pow is > 3 but the substance is poorly soluble in water (< 0.002 mg/L).

- Chronic toxicity is not to be expected based on the experimental results for Daphnia (21 -d NOEC >= 10 mg/L, BASF SE, 2014, report no. 51E0387/05E012) and algae (72 -h NOErC > 100 mg/L; BASF SE, 2010, report no. 60E0387/053371).

 

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 to be classified as chronically hazardous to the aquatic environment (chronic 3).

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 algae and daphnids, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available for algae (72-h NOErC >= 100 mg/L) and daphnids (21 -d NOEC >= 10 mg/L) indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for non-rapidly degradable substances.

- Acute toxicity data:

Acute toxicity to aquatic organisms (LC/EC50) is > 100 mg/L in freshwater (96-h LC50 fish > 100 mg/L).

The substance is not rapidly biodegradable and the log Kow is > 4 but the substance is only poorly soluble in water (< 0.002 mg/L).

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