Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

biodegradation in water: simulation testing on ultimate degradation in surface water
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water
Justification for type of information:
According to column 2 of REACH Annex IX simulation testing on ultimate degradation in surface water does not need to be conducted, if the substance is highly insoluble in water. 1,3,5-Triazine-2,4,6-triamine, deammoniated is insoluble in water. Therefore testing is scientifically not justified. Sediment simulation studies should be performed if the substance has a high potential for adsorption to sediment. Based on the physico-chemical properties of 1,3,5-Triazine-2,4,6-triamine, deammoniated the substance can be expected to to have a low potential for adsorption (e.g. highly insoluble in water and organic solvents) .In addition, direct and indirect exposure of sediment is unlikely to occur. 1,3,5-Triazine-2,4,6-triamine, deammoniated is used as regenerator in salt bath nitrocarburizing processes. The nitrocarburizing process is is operated effluent-free and is equipped with an efficient extractor system and exhaust air cleaning plant.
