Conclusion on classification
Aquatic compartment:
Harmonized classification regarding environmental hazards
In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1 or Table 3.2, propylenediamine is officially not classified.
Self-classification regarding environmental hazards
Following CLP (GHS-EU), the substance is not to be classified as acutely or chronically hazardous to the aquatic environment.
Rationale:
1) The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
2) Chronic data are only available for algae and aquatic invertebrates; therefore, classification is based on the available chronic (aquatic invertebrates and algae) and acute toxicity data (fish).
2a) Chronic toxicity data: The long-term effect values are greater than 1 mg/L for aquatic invertebrates and algae. The substance is rapidly degradable. Propylenediamine (CAS 78-90-0) 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.
2b) Acute toxicity data: The substance is rapidly degradable The log Kow is < 4 and the (estimated) BCF is < 500. The lowest LC50 for fish is 1010 mg/L and thus 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 1272/2008).
It can be concluded that the substance is not to be classified as chronically hazardous to the aquatic environment.
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).
