Description of key information

Melam is only slightly soluble at 24.5 mg/L water at 20 °C.

Key value for chemical safety assessment

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

Additional information

Three sources are available. Two water solubility studies by R. Kierkels, 2008 and 2011, and the water solubilities estimated from the 3 aquatic toxicity studies, reported in section 6.1.

The maximum concentrations in the 3 aquatic toxicity studies, obtained after preparing a suspension of 100 mg melam/L water or aqueous medium at ca. 20 °C, ranged from 8.4 to 14 mg/L and are in reasonable agreement with the results obtained by Kierkels 2011 of 24.5 mg/L pure water at 20.0 °C.
