Description of key information

Tartaric acid and its salts have negligible vapour pressures.

Key value for chemical safety assessment

Additional information

A collection of the vapour pressure values was performed for tartaric acid and its salts. As result, only a value was found for tartaric acid. Since this number is extremely low, the vapor pressure was deemed to be a negligible properties also for the tartaric acid salts (i.e. monosodium, monopotassium, sodium potassium, sodium, potassium and calcium tartrate).
