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 and chronic 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 (fish: 96-h LC50 >500 mg/L; daphnids: 48-h EC50 >500 mg/L; algae: 72-h EC50 > 500 mg/L).

 

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

- Chronic toxicity data:

Chronic data are available for freshwater algae (72-h NOErC ≥ 500 mg/L), indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.

- Acute toxicity data:

Fish and invertebrates are the trophic levels not covered by chronic data. Therefore, the assessment is based on the respective available acute toxicity data (fish: 96-h LC50 >500 mg/L; daphnids: 48-h EC50 >500 mg/L). The substance is rapidly biodegradable (freshwater); the Log Kow is < 4 (-0,77 at 25°C). 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: The substance is not to be classified as chronically hazardous to the aquatic environment.

 

Atmospheric compartment

The substance is not in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.

The substance does not belong to the greenhouse gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and in Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.
