EC number: 271-237-7 | CAS number: 68526-89-6 A complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isononanal from the hydroformylation of octene. It consists predominantly of C9-10 primary aliphatic alcohols, C10-20 dimer alcohols, C>18 acetals and esters and C>18 acid sodium salts and boils in the range of approximately 200°C to 400°C (392°F to 752°F).

Key value for chemical safety assessment
Additional information
Due to its composition, the partition coefficient n-octanol / water (Pow) of the test item can only be estimated from the single solubilities in n-octanol and in water.
The solubility in water is not a constant but increases with the mass of test item applied in the experiment. This is because the test item is a mixture. Every constituent contributes to a different degree to overall solubility, depending on its own individual solu-bility and its mass fraction in the test item. Therefore, results depend on the proportions of test item and water used in the respective experiment
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).
