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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 270-726-2 | CAS number: 68477-35-0 A complex combination of hydrocarbons from the distillation of saturated and unsaturated aliphatic hydrocarbons usually ranging in the carbon numbers C3 through C6. It consists of saturated and unsaturated hydrocarbons having carbon numbers in the range of C3 through C6, predominantly piperylenes.

Description of key information
Data are available for 68476-55-1 from two biodegradation screening studies indicating only a very low level of biodegradation over 28 days. However, it is difficult to assess the persistence of UVCB streams using standard test methods as the tests measure the properties of the whole substance but do not provide information on the individual constituents. Representative components of these streams, alkanes and alkenes with a carbon number of C5 to C6, were predicted by two QSAR models, Biowin and BioHCwin, not to be persistent. Members of this category are therefore not considered to be readily biodegradable but their components are expected to be biodegradable on the basis of the QSAR estimates for representative components.
Additional information
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.
