The OECD document contains following statement: (page 16):
"Long chain aliphatic alcohols are extremely weak acids and only dissociate under strongly basic conditions (pH >16 approximately). In the range of pH usually considered relevant to the environment, i.e. pH 4-9, these substances will be non-ionised."

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.
