Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 271-239-8 | CAS number: 68526-91-0 A complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isotridecanal from the hydroformylation of dodecene. It consists predominantly of C13-14 primary aliphatic alcohols, C22-28 dimer alcohols, C26 acetals and esters, and C>10 acid sodium salts and boils in the range of approximately 250°C to 450°C (482°F to 842°F).

Key value for chemical safety assessment
Additional information
In Annex IX of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on aquatic organisms.
Since the results of the short-term test indicate that Daphnia magna is the most sensitive species, it is supposed that aquatic invertebrates will be also more sensitive to long-term exposure of the test mixture than organisms of the other trophic levels (e.g. fish or algae). Therefore, and for reasons of animal welfare, long-term studies on fish does not need to be conducted and possible chronic effects of the mixture “dodecene, hydroformylation products, high-boiling” will be evaluate in a long-term test with Daphnia magna (s. chap. 6.1.4).
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.
