Key result
Remarks on result:
other: The test substance is hygroscopic
Details on results:
Very soluble in water.

The test substance is hygroscopic.The critical humidity is 38-40 % at 25 °C. This means that the product normally absorbs moisture and becomes wet and dissolves if exposed to air at normal weather conditions.
The substance is very soluble in water (> 10000 mg/L).

Description of key information

The substance is very soluble in water.

Key value for chemical safety assessment

Water solubility:
100 g/L
