Description of key information

OECD Guideline 105, EU Method A6, GLP, key study, validity 1:
Water solubility = 663.5 mg/L at 20°C (moderately soluble in water).

Key value for chemical safety assessment

663.5 mg/L
at the temperature of:
20 °C

Additional information

Experimental data, litterature data and QSAR result are available to determine the water solubility of TBEP.

According to the key study, performed according to OECD Guideline 105 and EU Method A6 with GLP statement, the water solubility of TBEP was determined to be 663.5 mg/L (flask method) at 20°C with a pH value of 6.5. Therefore, TBEP is considered moderately soluble in water.

This value is supported by a QSAR calculation at 604 mg/L.
