Description of key information

The endpoint is waived because the substance does not melt before the decomposition, which starts around 176°C, so the vapour pressure will be low.

Based on its multiple hydroxylgroups and carboxylic acid salt functionality the pure substance will exhibit negligible vapor pressure. Because of its high polarity the substance always contains a few % of water so the vapour pressure exhibited by this substance is expected to be that of the adherent water.

Key value for chemical safety assessment
