Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 271-816-4 | CAS number: 68609-04-1 The complex combination of hydrocarbons produced by the distillation of products from the air oxidation of cyclohexane after removal of acidic materials. It consists of hydrocarbons having carbon numbers predominantly in the range of C6 through C12 and boiling in the range of approximately 172°C to 324°C (342°F to 615°F).

Description of key information
The mixture is partly biodegradable.
Key value for chemical safety assessment
Additional information
The complex mixture cyclohexane, oxidized, non-acidic by-products, distn. residues was shown to be partly biodegradable in the Manometric Respirometry Test (OECD 301 F) using non-acclimated domestic sludge. Biodegradation was between 30 and 40% after 26 days based on BOD [BASF 1997].
This result is supported by biodegradation results of the analytically determined components of the mixture. Based on studies and QSAR calculations the biodegradation potential for the known mixture components range from readily biodegradable (according to OECD criteria) to moderately biodegradable and not biodegradable.
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.
