Description of key information

Water solubility [Fatty alcohols C16 – C18 (even numbered), branched and linear]: <0.15 mg/l at 20°C (EU Method A.6)

Key value for chemical safety assessment

Additional information

Fatty alcohols C16 – C18 (even numbered), branched and linear is a substance of unknown or variable composition (UVCB)containing linear and branched alcohols with carbon number in the range C14-C20. A measured water solubility of <0.15 mg/l at 20°C and pH 6.7 was determined for the whole substance in accordance with EU Method A.6. The result is considered reliable and selected as key study. This value is supported by predicted water solubility in the range 1.9E-03 - 1.4E-01 mg/l which was determined for the constituents of the substance using a validated QSAR estimation method. In a secondary source to which reliability could not be assigned, the substance was reported as insoluble.
