Alkyl-1,3-diaminopropanes are for more than 99% protonated under
environmental conditions. This means that they will behave as salts in
water and will have a very low vapour pressure. The solubility of these
waxy cationic surface active substances will be influenced by the pH and
is difficult to determine because of the surface active properties. As
an alternative as suggested by the REACH guidance R.7 the CMC at pH 7
was determined. Evaporation from water is based on the low vapour
pressure and the observed CMC values very unlikely. The actual dissolved
concentration in water will be extremely low as the alkyl-1,3
-diaminopropanes will sorb strongly to sorbents both based on
hydrophobicity and ionic interaction where the ionic interaction will
govern the partitioning process.
