Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Log Kow: 2.0 to >6.0. Approximately 92% m/m of Hamaca synthetic crude is predicted to have log octanol-water partition coefficient >6.0.

Key value for chemical safety assessment

Additional information

The calculation was done by the SPARC v.4.2 model (calculation of Log partition coefficient octanol/water) in conjunction with the known compositional data for Hamaca synthetic crude. The figures represent the spread of calculated values for typical hydrocarbon components taken from the CONCAWE 1500 library. Predicted values for higher molecular weight hydrocarbons is >6.0, but such values are notional, since no correlation has been established between calculated and experimental values.
