Description of key information

No surface tension data is available for 2,2,3-trimethylbutane. However, data is available for hydrocarbons, C7-C9, isoalkanes and is being read across to using the category approach explained in the category justification document attached to Section 13 of the dossier.

The surface tension of hydrocarbons, C7-C9, isoalkanes is between 18 and 22 mN/m at 25°C.

Key value for chemical safety assessment

Additional information

Wilhelmy plate method is used to measure the surface tension using a standardized plate with a plate tensiometer. Using this method the surface tension of

hydrocarbons, C7-C9, isoalkanes is between 18 and 22 mN/m at 25 °C. This data is used as read across for 2,2,3-trimethylbutane.
