Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 viscosity of the members of this category ranges from 7.5 to 11.2 µPa at 27°C.

Key value for chemical safety assessment

Additional information

Viscosity data were available for methane, propane, ethane, isobutane and butane. This information was taken from the CRC Handbook (2008) handbook which is considered reliable for assessment. The data from these substances will be read across the category. However, at normal ambient temperature and pressure these substances exist in the form of a gas and hence, liquid viscosity values are not considered relevant.
