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).

Description of key information
The substance Octene, hydroformylation products, high boiling is considered to be ultimately biodegradable.
Key value for chemical safety assessment
Additional information
Octene, hydroformylation products, high boiling is a UVCB consisting of a multitude of constituents that cannot be characterized properly. Therefore, a result from a screening test according to OECD TG 301 can technically speaking not be used to determine the readily biodegradability of a complex UVCB. However, a GLP guideline study according to OECD TG 301 B on the biodegradability of the test substance is available (BASF, 2008). The degradation rate of 80 -90 % after 28 days reveals a high degradation rate and that further degradation of the test substance can be expected. A GLP guideline study according OECD TG 301 B enhanced with prolonged test duration shows a degradation rate of 100% after 42 days (BASF, 2015). The result shows that 100% of the TOC of the UVCB – measured according to ISO 9439 - is mineralized within 42 days. In addition, the degradation rates of the OECD TG 301 B study in 2008 are well supported by the rates of the enhanced OECD TG 301 B test in 2015.
Therefore, it can be concluded that the substance Octene, hydroformylation products, high boiling is ultimately biodegradable.
