Description of key information

The viscosity of toluene at 25°C is 0.56 mPa s

Key value for chemical safety assessment

0.56 mPa · s (dynamic)
at the temperature of:
20 °C

Additional information

The CRC handbook of chemistry and physics is a peer reviewed handbook and is considered reliable and suitable for use as the key study for this endpoint. In addition, this reference was used as the key study in the EU RAR (2003) for toluene.

The supporting study (EHC, 1985) is also a peer reviewed handbook and supports the value reported in the key study, giving a viscosity of 0.6 cp at 20°C.
