Conclusion on classification

Official classification regarding environmental hazards:

Aquatic compartment

In accordance with Regulation (EC) No 1272/2008 Annex VI Table 3.1 or Table 3.2: no data found.

 

Self-classification

Aquatic compartment

Following CLP (GHS-EU), 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 only for algae (EC10 > 1 mg/L; lowest available EC10: 72 -h ErC10 = 19.5 mg/L, read-across to CAS 122 -20 -3); therefore, classification is based on the available chronic (algae) and acute toxicity data (fish: 96 -h LC50 > 1000 mg/L; Daphnia: 48-h EC50 > 100 mg/L).The data available for chronic classification are not adequate conclusive but not sufficient for classification.The chronic data indicate that the substance is not to be classified as hazardous to the aquatic environment.The lowest acute effect value is greater than 100 mg/L, the substance is not readily biodegradable, but its log Kow is < 4. In conclusion, the substance is not be classified as chronically hazardous to the environment.

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 value is > 1 mg/L (lowest acute effect value: EC50 > 100 mg/L).

Chronic data are available only for algae (EC10 > 1 mg/L; lowest available EC10: 72 -h ErC10 = 19.5 mg/L, read-across to CAS 122 -20 -3); therefore, classification is based on the available chronic (algae) and acute toxicity data (fish: 96 -h LC50 > 1000 mg/L; Daphnia: 48-h EC50 > 100 mg/L).

- Chronic toxicity data:

Chronic data are available for algae (ErC10 = 19.5 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. Based on the chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data:

The lowest effect value for acute toxicity to aquatic organisms is an EC50 > 100 mg/L.

The substance is not rapidly biodegradable, but the log Kow is <4. Based on the acute toxicity data, the substance is not to be classified as chronically hazardous to the aquatic environment.

It can be concluded that the substance is not chronically hazardous to the aquatic environment.
