Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 273-110-1 | CAS number: 68938-03-4 The complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isononanal. It consists predominantly of C6 olefins and paraffins and C9 alcohols and aldehydes and boiling in the range of approximately 110°C to 202°C (230°F to 396°F).

Description of key information
Oxooil LS9 is not expected to be toxic to sediment dwelling organisms. No study is therefore proposed.
Key value for chemical safety assessment
Additional information
The measured adsorption coefficient of Oxooil LS9 (Log Koc 3.2) indicates that there would be potential for distribution to the sediment. However, Oxooil LS9 is a poorly soluble, complex mixture (UVBC), and a toxicity test using sediment dwelling organisms would require exposure via a method based on the principles of ‘water accommodated fractions’. Since it would not be possible to attribute any potential effect of Oxooil LS9 to any individual component(s), analytical determination of the concentration of Oxooil LS9 in the sediment and pour water would be extremely challenging. Hence, the equilibrium partitioning method has been used to assess hazard to sediment organisms, and based on the results of the CSA and in accordance with REACH Annex X section 9.5.1, long-term testing to sediment organisms is not proposed.
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.
