Description of key information
Additional information
The acute toxicity of the substance was determined in short-term toxicity tests on fish, Daphnia and algae. The most sensitive test organism was Pseudokirchnerialla subcapitata (algae). In a guideline study according to OECD 201 an EC50(72 h) of 1.7 mg/L (NOEC(72 h): 0.25 mg/L) was determined based on reproduction. For Daphnia magna an EC50(48 h) of 17.5 mg/L was determined in a guideline study according to EU method C.2. The LC50 96 h) determined for Poecilia reticulata was 180 mg/L. The test was performed under EC guideline and under GLP.
Experimental data on the chronic toxicity of the substance are not available. The assessment is therefore based on read across data available for the structural analogue Amines, polyethylenepoly-, triethylenetetramine fraction (CAS 90640-67-8). Based on the reproduction of Daphnia magna an EC10 (21 d) of 1.9 mg/L was determined.
An EC50(2h) of 164 mg/L was determined in a study on the inhibition of the respiration of nitrifying bacteria. The determined EC10 (2 h) was 46 mg/L.
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).
