Description of key information
With high probability acutely not harmful to fish
Key value for chemical safety assessment
Additional information
Data on the toxicity of the mixture N3/N4-amine to fish are not available.
Considering the constutients N-(2 -aminoethyl)-1,3 -propanediamine (CAS 13531-52-7), N,N'-bis(3 -aminopropyl)ethylenediamine (CAS 10563-26-5) and ethylenediamine (CAS 107-15 -3), N3/N4 -amine may be considered as acutely not harmful to fish. Tests with these compounds on fish resulted in LC50 (96h) values in the range from 115.7 to 318.1 mg/L. Test data on 1,3-propanediamine, N,N''-(iminodi-2,1-ethanediyl)bis- (CAS 58214-71-4) are not available. Therefore, data from the structurally analogous compound tetraethylenepentamine (TEPA; CAS 112 -57 -2) was used: 96-h LC50: 420 mg/L.
In conclusion, the mixture N3/N4-amine is concluded by weight-of-evidence to be with high probability acutely not harmful to fish.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
