Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, no data were found for the reaction mass of 2 -piperazine-1 -ylethanol and piperazine-1,4 -diethanol and piperazine and water or for two of its major components (CAS 103 -76 -4, CAS 122 -96 -3).

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, the major component piperazine (CAS 110 -85 -0) is not officially classified.

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is not to be classified as dangerous for the environment.

Rationale:

- The acute toxicity to aquatic organisms (LC/EC50) is greater than 100 mg/L in freshwater.

- The reaction mass is not readily biodegradable (freshwater and marine water), but the log Pow is <3.

 

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

- Chronic toxicity data:

Chronic data are available only for algae (ErC10 > 120 mg/L) indicating that the reaction mass 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:

Acute toxicity to aquatic organisms (LC/EC50) is greater than 100 mg/L in freshwater.

The substance is not rapidly biodegradable, but the log Kow is <4.

 

Atmospheric compartment

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

The constituents do not belong to the green house 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.
