Description of key information
The water solubility of a commercial sample of nonan-1-ol is 69.54 mg/L at 20°C. It is supported by a value of 128 mg/L at 20 ºC for the pure substance, taken from a reliable reference source for solubility data.
Key value for chemical safety assessment
- Water solubility:
- 69.54 mg/L
- at the temperature of:
- 20 °C
Additional information
The solubility of 69.54 mg/L was determined in accordance with OECD 105. The result is considered reliable.
It is supported by a value of 128 mg/L at 20 ºC, measured using a slow-stirring method and reported in a reliable reference source for solubility data (Letinski) which is corroborated by a value of 140 mg/l from an IUPAC reference source (Barton).
The value of 128 mg/L at 20 ºC, taken from literature for pure alcohol is used in exposure modelling. All the available reliable results consistently indicate that nonan-1-ol is moderately soluble in water.
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.
