Additional information
Conclusion on classification
Official classification regarding environmental hazards:
Aquatic compartment
In accordance with Regulation (EC) No 1272/2008 Annex VI Table 3.1 or Table 3.2: officially not classified.
Self-classification
Aquatic compartment
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 hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
- Chronic data are available for all three trophic levels (NOEC/EC10 > 1 mg/L); therefore, classification is based on the available chronic toxicity data.
- Chronic toxicity data:
The EC10 values are greater than 1 mg/L. The substance is rapidly degradable and its calculated BCF (weight-of-evidence approach) is < 500.The chronic data indicate that diethylamine 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.
