Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A trend of decreasing water solubility with increasing carbon number is seen for category members.

Key value for chemical safety assessment

Additional information

Water solubility decreases with increasing carbon number across the category, with a very similar trend for both the alpha olefins and olefins. Data is available for category members with carbon numbers of C6 to C24. Two QSAR have been used to support the experimental data and to fill data gaps.

At C6 water solubility is around 47 mg/l. At around C10 -12 water solubility is <0.1mg/l, indicating that the compounds at this carbon number and higher are considered insoluble.
