Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Only supporting data is available for Hydrocarbons, C11-C12, n-alkanes, <2% aromatics. However, key and supporting data is also available for structural analogue Hydrocarbons, C10-C13, n-alkanes, <2% aromatics and presented in the dossier. This data is read across to Hydrocarbons, C11-C12, n-alkanes, <2% aromatics based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.

The calculated vapour pressure of the substance Hydrocarbons, C10-C13, n-alkanes, <2% aromatics, is maximum 0.11 kPa at 25°C.

This data is used for read across to Hydrocarbons, C11-C12, n-alkanes, <2% aromatics.

The calculated vapour pressure of Hydrocarbons, C11-C12, n-alkanes, <2% aromatics is 0.034 kPa at 20°C.

Key value for chemical safety assessment

Vapour pressure:
0.034 kPa
at the temperature of:
20 °C
