Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Remarks on result:
other: Standard concentration assumed.
Conclusions:
The surface tension of Hydrocarbons, C6, n-alkanes, isoalkanes, cyclics, n-hexane rich is 19.0 mN/m.
Executive summary:

The surface tension of Hydrocarbons, C6, n-alkanes, isoalkanes, cyclics, n-hexane rich has been taken from Exxon Mobil Chemicals 2010. The full study is not available, but the summary states that the Wilhelmy plate method was followed.

Description of key information

There is vapour pressure data available for Hydrocarbons, C5 -C7, n-alkanes, isoalkanes, n-hexane rich. Additionally, data is available for Hydrocarbons, C6, n-alkanes, isoalkanes, cyclics, n-hexane rich and is presented based on analogue read across.

The surface tension of Hydrocarbons, C5-C7, n-alkanes, isoalkanes, n-hexane rich is ca 19 mN/m at 25°C as tested by method ASTM D971M. This was based on neat material rather than in solution.

Key value for chemical safety assessment

Additional information

The surface tension was reported based on the neat material rather than in solution. However, surface tension may be waived:

In accordance with column 2 of REACH Annex, the surface tension study does not need to be conducted as, based on the structure of this substance, surface activity is not expected or predicted and surface tension is not a desired property of the material.
