Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

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:

- Acute toxicity data

The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L (marine data: 72-h ErC50 = 3.1 mg/L;S. costatum, Eide-Haugmo et al., 2012/2009).

Rationale:

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

- Chronic toxicity data:

Chronic data are only available for aquatic algae (72 -h ErC10 = 10 mg/L; DSM, 2012). The substance is rapidly degradable and the EC10 is > 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 and daphnids are the trophic levels not covered by chronic data. Therefore, classification is based on the respective acute effect data. The 96-h LC50 for fish is 115 mg/L (measured, BASF AG, 1993); for daphnids, the 48-h EC50 is 63 mg/L; DSM, 2012. Both values are > 1 mg/L. Moreover, the substance is rapidly degradable. Therefore the substance is not to be classified as chronically hazardous based on acute toxicity data. 

Conclusion: the substance is not to be classified as chronically hazardous to the aquatic environment.
