EC number: 265-047-3 | CAS number: 64741-47-5 A complex combination of hydrocarbons separated as a liquid from natural gas in a surface separator by retrograde condensation. It consists mainly of hydrocarbons having carbon numbers predominantly in the range of C2 to C20. It is a liquid at atmospheric temperature and pressure.

Description of key information
A measured Koc is not available for any of the streams in this category.
It is not feasible to perform simulation tests on complex, volatile UVCBs.
As the log Kow of some streams is >3 the adsorption/desorption endpoint cannot be waived. However, ECHA's Guidance on Information Requirements and Chemical Safety Assessment R7a Endpoint Specific Guidance (2008) indicates that, before commissioning a new study, alternative sources of data (e.g. QSAR) on the adsorption/desorption potential of a chemical should be used. Soil sorption of non-ionic substances can be estimated from their log Kow. Several QSAR have been developed that calculate the Koc of non-polar hydrocarbons on the basis of their log Kow (e. g. Sabljic and Gusten, 1995). The log Kows for representative components on these streams were identified from the compositional data. The representative components are presented in Section 2.3.
The predicted log Kocs for the representative components in this category range from 1.3275 - 6.67 across both QSARs.

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.
