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.
