Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The kinematic viscosity of Dibutyldiglycol at 20°C was determined in a study analogous to OECD guideline 114 using a capillary viscosimeter of the Ubbelohde type. The kinematic viscosity of Dibutyldiglycol at 20°C is: 2.692 ± 0.004 mm2/s.

The GESTIS database reports a dynamic viscosity at 20 °C of 2.4 mPa s without giving experimental details.
