Executive summary:

The viscosity of Hydrocarbons, C6, isoalkanes, <5% n-hexane has been taken from ExxonMobil Chemical 2010. Under the conditions of this study a viscosity of 0.46 mm2/s at 20°C was determined for the test substance, Hydrocarbons, C6, isoalkanes,

Description of key information

There is no data available for 2,2 -Dimethylbutane. Data is available for Hydrocarbons, C6, isoalkanes, <5% n-hexane and Isohexane and this data is used for read across to 2,2 -Dimethylbutane.

The viscosity of Hydrocarbons, C6, isoalkanes, <5% n-hexane ranges from 0.3 to 0.6 mm2/s at 20°C.

Key value for chemical safety assessment

Additional information

There is no data available for 2,2 -Dimethylbutane. Data is available for Hydrocarbons, C6, isoalkanes, <5% n-hexane and Isohexane and this data is used for read across to 2,2 -Dimethylbutane.

The viscosity of Hydrocarbons, C6, isoalkanes, <5% n-hexane ranges from 0.3 to 0.6 mm2/s at 20°C, measured using ASTM D 7042. This range was agreed by the consortium to represent the substance.
