Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on the estimated vapour pressures of the pure alkyl dimethylamine oxides, the vapour pressure is expected to be in the range of 4.6E-07 and 2.2E-05 Pa at 25 °C

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

It is not possible to measure the vapour pressure of the substance as it decomposes before boiling. The vapour pressures of the individual alkyl dimethylamine oxides were estimated using MPBPWIN v 1.43 (modified grain method). Based on these calculations, the vapour pressure of the substance is estimated to be between 4.6E-07 and 2.2E-05 Pa at 25 °C.
