Description of key information

Water solubility (dodecamethylpentasiloxane): 7.0E-05 mg/l at 23°C

Key value for chemical safety assessment

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

Additional information

A measured water solubility value of 70.41 ± 8.3 ppt (7.0E-05 mg/l) at 23°C was determined for the test substance using a generally accepted scientific method. The result is considered to be reliable and was selected as key study. This is supported by a water solubility of 7E-05 mg/l at 25°C obtained in a secondary source to which no reliability could be assigned. The supporting study is in good agreement with the key study. The test substance is insoluble in water.
