Description of key information
The water solubility is < 0.05 mg/L at 20 °C.
Key value for chemical safety assessment
Additional information
The key value of water solubility of the substance is estimated by using category approach, i.e. read-across from its main constituent C16 palmitic acid (CAS 57-10-3). Because water solubility of fatty acid decreases with the chain length, the C16 palmitic acid has the highest water solubility within this composition. It is supported by data for the substance itself, but with less precision (< 50 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
