Description of key information

Disodium persulfate was not tested for water solubility. Based on published data, the water solubility of disodium persulfate was determined at ca. 730 g/L at 25 °C . Thus, the test substance was considered as very soluble.

Key value for chemical safety assessment

Water solubility:
730 000 mg/L
at the temperature of:
25 °C

Additional information

Based on published data, the following results were obtained for water solubility of disodium persulfate: 730 g/L (25 °C) (OECD-SIDS Report, 2005) and 556 g/L (20 °C) (NICNAS Report, 2001). As the first value was considered more reliable and it was chosen as the key value.
