Description of key information

The pKa values calculated with ADC/pKa v 12.00 for the sufonate groups are -1.61>pKa>-0.79 and -1.56>pka>-0.79 for the two components of the substance.

Key value for chemical safety assessment

pKa at 20°C:
-1.61

Additional information

The pKa values calculated with ADC/pKa, version 12.00, for the sulfonate groups are -1.61<pKa<-0.79 and -1.56<pka<-0.79 respectively for the two main components of the test substance.

Under environmental conditions, the substance dissociates completely in water.
