Additional information

Data is not available for partition coefficient of sodium benzoate itself. Given the dissociation constant of benzoic acid (pKa is 4.03) it is anticipated that in solution sodium benzoate will be largely dissociated into benzoic acid. Hence read-across of the partition coefficient study from benzoic acid (Berthod, 1988) is justified. Log Pow is therefore 1.88.
