Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

N-C16-18-alkyl-(even numbered, C18 unsaturated) trimethylpropane-1,3-diamine is considered to be chemically stable.

Additional information

N-C16-18-alkyl-(even numbered, C18 unsaturated) trimethylpropane-1,3-diamine have a short predicted half-life in air but because there are no important releases into the atmosphere and volatilisation is expected to be negligible, this removal mechanism is thought to be of low relevance.

N-C16-18-alkyl-(even numbered, C18 unsaturated) trimethylpropane-1,3-diamine do not contain hydrolysable covalent bonds. Cleavage of a carbon-nitrogen bond under environmental conditions is only possible with a carbonyl group adjacent to the nitrogen atom. Degradation of N-C16-18-alkyl-(even numbered, C18 unsaturated) trimethylpropane-1,3-diamine through hydrolysis is therefore not considered.

Direct photolysis of N-C16-18-alkyl-(even numbered, C18 unsaturated) trimethylpropane-1,3-diamine in air/water/soil will not occur, because it does not absorb UV radiation above 290 nm.Photo transformation in air/water/soil is therefore assumed to be negligible.
