Description of key information

Water solubility (hexamethyldisiloxane): 0.93 mg/l at 23°C

Key value for chemical safety assessment

Water solubility:
0.93 mg/L
at the temperature of:
23 °C

Additional information

A water solubility value of 930.66 ± 633.7 ppb (0.93 mg/l) at 23°C was determined for the substance in a reliable study conducted according to generally accepted scientific principles. The result is considered to be reliable and selected as key study.

In secondary sources to which reliability could not be assigned, water solubilities values of 0.6 mg/l, 0.9 mg/l and approximately 2 mg/l at 25°C were reported for the substance.

The supporting studies are all in agreement with the key study that the substance is slightly soluble in water.
