Description of key information

The water solubilities of the 5 aromatic sulphonic acids were all relatively high; ranging from 1117 to 1318 g/L for all except cumene sulphonic acid which had a solubility of 821 g/L.

Key value for chemical safety assessment

Water solubility:
50 000 mg/L
at the temperature of:
20 °C

Additional information

A representative value for water solubility of 50000 mg/l has been indicated as key value for chemical safety assessment, because 500 is the maximum acceptable value from EUSES 2.0 model for environmental risk assessment
