Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Hydrocarbons, C13-C16, isoalkanes, cyclics, <2% aromatics is a hydrocarbon UVCB consisting of a number of hydrocarbon components each with their own log Kow value. As such, the generation of a single experimental log Kow value for a UVCB is of limited utility because the environmental risk assessment is performed at the component level. Reliable and valid QSARs are available to model log Kow for hydrocarbons, and predicted log Kow values for relevant components of Hydrocarbons, C13-C16, isoalkanes, cyclics, <2% aromatics using the EPIWEB KOWWIN QSAR are available in Section 13 of IUCLID (see “PETRORISK” file). This QSAR meets all conditions as set in section 1.3 of Annex XI.
