Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 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 CLP (GHS-EU), 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.

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

 

Chronic toxicity data:

Chronic data are available for algae (ErC10 = 8.25 mg/L) and daphnids (NOEC = 3.8 mg/L). A  study on long-term toxicity on fish was waived (see IUCLID Ch. 6.1.2). The available data indicate 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:

Acute toxicity to aquatic organisms (LC/EC50) is between 10 and 100 mg/L (fish >100 mg/L in pH-adjusted test solution) in freshwater. The substance is rapidly degradable and the log Kow is <4. Based on the categories outlined in Table 4.10(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/008 the substance is not to be classified as chronically hazardous to the aquatic environment.

 

Conclusion

Piperidine is not to be classified as acutely or chronically hazardous to the aquatic environment.
