Description of key information
The water solubility of Alcohols, C12-15, branched and linear is <1.3 mg/L at 20°C and pH 7.
Key value for chemical safety assessment
Additional information
The solubility of <1.3 mg/L at 20°C and pH 7 was determined for Alcohols, C12 -15, branched and linear in accordance with OECD 105. The result is considered to be reliable.
The key study is supported bt water solubility values of 0.8 mg/l at 20°C and 0.64 mg/l at 25°C.
Whilst water solubility for a multi-constituent or UVCB substance is not meaningful scientifically for the purpose of assessment of exposure or risk, a limit value has been determined for a commercial sample. This is useful for reference. Exposure and risk are assessed on the basis of water solubility of the individual constituents. Dodecan-1-ol, tetradecan-1-ol and pentadecan-1-ol have water solubility values of 1 mg/L at 23°C, 0.35 mg/l at 25°C and 0.1 mg/l at 20°C respectively.
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.
