Executive summary:

According to MPBPVP v1.43 (EPISUITE v4.11), gallic acid has a vapor pressure of 1.54E-06 Pa at 25°C.

Description of key information

As specified in column 2 of Annex VII of Regulation 1907/2006 (REACH), if a melting point is between 200 and 300°C, a limit value based on measurement or a recognized calculation method is sufficient.

Litterature reports that gallic acid can sublime and/or decompse from 210°C.

Endpoint based on recognized calculation method is therefore sufficient: according to MPBPVP v1.43 (EPISUITE v4.11), gallic acid has a vapor pressure of 1.54E-06 Pa at 25°C

Key value for chemical safety assessment

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