Description of key information

Water solubility (HHPAc): 4.2 g/L at 20°C and pH 2.9

Key value for chemical safety assessment

Water solubility:
4.2 g/L
at the temperature of:
20 °C

Additional information

The substance rapidly hydrolyses in water to yield the corresponding acid. Water solubility of hexahydrophthalic acid has been investigated in accordance with OECD/EU test methods and determined to be 4.2 g/L at 20 ± 0.5 °C and pH 2.9.

The above solubility, as function of pH, was estimated taking account of the dissociation of this acid.
