Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Calculated on representative main component:

0.582 Pa at 25°C

Key value for chemical safety assessment

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

Additional information

The test substance contains ca.16% water which has an exetremly very high vapour pressure (3170 Pa at 25°C) than that of the major component (estimated < 1 Pa) and this is a difficulty for getting an accurate measured value. Due to this the vapour pressure of the representative main component has been calculated.

The calculation was based on Modified Grain Method using recommended MPBPVP (v1.43) module of software EPI Suite v.4.11.

Additionally, an other calculated value using ACD/Labs (Software V11.02 (© 1994-2017 ACD/Labs) cited in SciFinder was stated to be 0.3 Pa at 25°C.
