Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapour pressure of Hydrocarbons, C10-C13, aromatics, <1% naphthalene at 20 deg C is typically between 0.002 and 0.003 kPa.

This data is read across to Hydrocarbons, C11-C15, aromatics, <1% naphthalene.
