Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to handbook data (Kirk-Othmer, 1991) as well as to a QSAR estimation

(EPIWIN, 2009), trimethylolpropane is reported to be very soluble in water since roughly 100 - 1000 g/L TMP are dissolved at 25 °C. At elevated temperatures the solubility even increases as indicated in the Kirk-Othmer handbook where it is reported that 200g of TMP dissolve in 100 g water at 90 °C.

Key value for chemical safety assessment

Water solubility:
100 g/L
at the temperature of:
25 °C
