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

The results of a semi-static exposure test on Pimephales promelas as presented by Brooke and co-workers in 1984 indicate that propylenediamine (CAS 78 -90 -0) is not acutely harmful to fish if the stock solution is adjusted to the pH of the dilution water. The 96 -h LC50 based on measured test item concentrations was determined to be 1010 mg/L. Broderius et al. (1995), also determined a 96 -hour LC50 value of 1267 mg/L for Pimephales exposed in a continuous flow-through system. No information is given whether the test solutions were neutralised.

It can be concluded that with high probability propylenediamine is acutely not harmful to fish.
