Description of key information

Parent substance EC 401 -280 -0

The key study (Ciba, 1985, OECD 301B revealed no significant degradation of the test item. The substance EC 401-280-0 hydrolyses in contact with water immediately. Therefore the hydrolysis products need to be considered.

Hydrolysis products:

bis(2 -ethylhexyl)amine

Di-(2-ethylhexyl)amine is considered to be moderately biodegradable(not readily biodegradable according to OECD criteria) in a weight of evidence approach.

1H-1,2,4 -Triazole

Data on1H-1,2,4t-triazole show that the substance is not readily biodegradable but significant degradation was observed in a field study in different soils (ECHA disseminated REACH dossier, 2014).


Formaldehyde is expected to be readily biodegradable at low concentrations (Gerike, 1990).
