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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The pour point of hydrocarbons, C13-C20, n-alkanes, iso-alkanes, cyclics, 40-60% aromatics is in the range of -6 to -35 °C.
Key value for chemical safety assessment
Additional information
There are no data available on the melting point/freezing point for hydrocarbons, C13-C20, n-alkanes, iso-alkanes, cyclics, 40-60% aromatics. For hydrocarbon UVCBs it is not possible to determine a single melting point, instead the pour point is determined. Based on an analogue approach data are read-across to both, hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) and hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%), in order to cover lower and upper ends of carbon range.
Data provided by ExxonMobil Chemical (2010a) and Petrochem Carless (2009a) show the pour point to be in the range of -18 to -35 °C at 1 atm, measured according to ASTM D5950 and ASTM D97, for hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, aromatics (2-30%). For hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%), data provided by ExxonMobil Chemical (2010b) and Petrochem Carless (2009b) show the pour point to be in the range of -6 to -30 °C at 1 atm, measured according to ASTM D5950 and ASTM D97.
A justification for the use of mentioned analogue substances for read-across is attached to IUCLID section 13.
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.
