Additional information

The toxicity of 1,2 -propanediamine (CAS 78-90 -0) towards microorganisms was determined in an OECD 209 study (BASF SE, 2021). The EC10 (3h) was 1.4 mg/L whereas the EC50 value was determined to be 120 mg/L. Furthermore, in a study with Pseudomonas putida according to DIN 38412-8, the 16-h EC50 was determined to be > 1000 mg/L for 1,2-propanediamine (CAS 78-90-0; Bayer Ag, 1979; report no. 790106 -1014).
