Key value for chemical safety assessment

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

Additional information

The water solubilities of the two main components of the submission substance were determined by the flask method according to EU A.6 / OECD TG 105. The water solubility of the sample HMD pure is 637 g/L at 20 °C. The water solubility of the sample BHMT pure is 437 g/L at 20 °C. The mean water solubility of 537 g/L is assumed for safety assessment purposes.
