Conclusion on classification

Official classification:

Aquatic compartment

In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1 or Table 3.2: no data found.

Self-classification:

Aquatic compartment

Following DSD/DPD, the substance is not to be classified as dangerous to aquatic organisms.

Rationale:

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

-      The substance is readily biodegradable in freshwater and the log Pow is <3.

-      The lowest chronic value is greater than 1 mg/L.

Following CLP (GHS-EU), the substance is not to be classified as acutely or chronically hazardous to the aquatic environment.

Rationale:

- The substance is not to be classified as acutely hazardousto the aquatic environment, since the lowest acute effect value is > 1 mg/L.

-      Chronic data are available only for Daphnia and algae (NOEC > 1 mg/L), therefore classification is based on the available chronic and acute toxicity data.

-      Chronic toxicity data: The NOEC values are greater than 1 mg/L. The substance is rapidly degradable and its experimentally determined BCF is < 500. The chronic data indicate that triethanolamine 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: The substance is rapidly degradable, the experimentally determined BCF is < 500. The lowest acute effect value is greater than 100 mg/L. Therefore no long-term hazard exists based on the categories outlined in Table 4.10(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/008.

 

Atmospheric compartment

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

 

The test substance does not belong to the greenhouse 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.
