Description of key information

Method A.6 Water solubility, Directive 92/69/EEC, published in OJ No L 383A, December 1992.
GLP study

Key value for chemical safety assessment

Water solubility:
279 000 mg/L
at the temperature of:
20 °C

Additional information

Water solubility test was performed for the test substance. Flask method was used.

The concentration of the substance in the aqueous solution was determined by spectrophotometric method (SFM).

The water solubility of the test substance - Humic acids, potassium salts - is 279 g/L.

Standard uncertainty of determination was estimated to 1.0 g/L.

Testing was performed at the temperature of 20°C.
