Additional information

There was no partition coefficient data available for hydroxylammonium nitrate. However, read across data for hydroxylammonium sulphate and hydroxylamine were available. The partition coefficient for hydroxylammonium sulphate was reported as -3.6 at 20°C and a pH of 3.2 (although it did state that the coefficient was dependant on pH). The partition coefficient for hydroxylamine was reported as -1.5. It is likely that the partition coefficient for hydroxylammonium nitrate will be similar to this value.
