Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reaction mass:
0.788 g/cm3 at 20 degrees C
Values cited at 20C: 789.33, 790kg/m3
Values cited at 25C: 785.05, 784.4kg/m3
Two separate TGD-approved handbooks agree that the substance has a density of 0.7855 g/cm3 at 20°C and a relative density of 0.8.

Key value for chemical safety assessment

Additional information

Company owned data from a study performed according to standard methods revealed a value of 0.788 g/cm3 at 20 degrees C for the reaction mass.


Multiple and consistent values are available from a number of sources. The key value is the value at 25C of 784.4C.


Information regarding density and relative density of IPA was sourced from CRC Handbook of Chemistry and Physics (81st Ed) and Fire Protection Guide to Hazardous Materials (13th Ed.), respectively. These handbooks which are known to contain peer-reviewed data of Klimisch-2 reliability state that the substance has a density of 0.7855 g/cm3or 785.5 g/L at 20°C and a relative density of 0.8.
