Description of key information
The water solubility of undecan-1-ol is 5.7 mg/L at 20°C.
Key value for chemical safety assessment
- Water solubility:
- 5.7 mg/L
- at the temperature of:
- 20 °C
Additional information
The solubility of 5.7 mg/L was determined in a reliable study.
It is supported by a value of 8.0 mg/L at 20 ºC, taken from a reliable reference source for solubility data which is closely corroborated by QSAR.
The value taken from literature for pure alcohol is used in exposure modelling.
Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:
As chain length increases, water solubility decreases, because the free energy required for a molecule to dissolve becomes less favourable for larger molecules.
