Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Official classification:
Aquatic compartment
According to Regulation (EC) No 1272/2008 Annex VI Table 3.1 and 3.2 the substance holds no relevant classification.
Self-classification:
Aquatic compartment
Following CLP (GHS-EU) the substance is not considered to be acutely hazardous to aquatic organisms.
Following CLP (GHS-EU) the substance is considered to be chronically hazardous to aquatic organisms (Category Chronic 3).
Rationale:
According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance (CAS 13531-52-7) is not to be classified as acutely hazardous to the aquatic environment since the lowest available acute effect value (LC/EC50) is > 1 mg/L (Daphnia magna, 48-h EC50 = 25.9 mg/L, BASF AG, 1989, study no. 1/0502/2/89-0503/89).
Long-term toxicity data are available for algae. Therefore, classification is based on the available chronic data and on acute toxicity data for the trophic levels not covered by chronic data (aquatic invertebrates and fish).
Chronic toxicity data:
The lowest EC10 is > 1 mg/L (72-h EC10 = 9.2 mg/L, BASF AG, 1990, study no. 2/0503/w503/89) 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:
The lowest L(E)C50 is > 10 and <= 100 mg/L (Daphnia magna, 48-h EC50 = 25.9 mg/L, BASF AG, 1989, study no. 1/0502/2/89-0503/89). The substance is not rapidly degradable, the log Kow is < 4, and the BCF value is < 500. Therefore, 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 to be classified as chronically hazardous to the aquatic environment (Category Chronic 3).
Conclusion:
Based on the available information, the substance is not
considered to be acutely hazardous to aquatic organisms. The substance
is chronically hazardous to aquatic organisms (Category Chronic 3).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
