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 (48h-EC50 = 37.4 mg/L, BASF AG, 1989, Report no. 1/0499/2/89). Chronic data are available for algae and invertebrates, therefore classification is based on the available chronic and acute toxicity data:

- Chronic toxicity data:

Chronic data are available for algae (72 -h ErC10 = 294.3 mg/L; BASF AG 1989, report no. 01/0499/2/89) and aquatic invertebrates (21 -d NOEC = 5.6 mg/L, read-across data from DETA, CAS 111-40-0; Akzo, 1992, report no. CRL F91183). According to the criteria outlined in Table 4.1.0(b) (ii) of the Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances, the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data:

Fish is the trophic level which is not covered by chronic data. Therefore, classification is based on the respective acute effect data. For fish, the 96h-LC50 is determined to be > 100 mg/L (96 -h LC50 = 215 - 316 mg/L; BASF AG, 1979, report no. 79/42). In addition, the substance is rapidly biodegradable and its log Kow is < 4. 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 to be classified as chronically hazardous to the aquatic environment.
