Description of key information

Dissociation constant 9.82 (calculation)

Key value for chemical safety assessment

pKa at 20°C:
9.82

Additional information

pKa (Benzyl Salicylate, 25 °C) = 9.82.

This suggests that the pKa of Benzyl salicylate is outside the environmentally relevant pH range (4 to 9 for surface waters, about 8 for marine environments and between 5.5 and 7.5 for agricultural soil and STP tanks - ECHA Guidance Ch R.7a ), and that the molecule therefore is undissociated under normal conditions.
