Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapor pressure of isophorone is 0.4 hPa at 20 °C (Hüls AG, 1981) in good agreement with data from other sources. In particular, vapor pressure data at a series of higher temperatures show a reasonable relationship between vapor pressure and temperature (vapor pressure curve). Experimental details have not been reported.

Key value for chemical safety assessment

Vapour pressure:
40 Pa
at the temperature of:
293.15 K
