Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

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.
