Description of key information

Additional information


TPSA has a measured Log Kow of 2.8 and based on this value the Exposure Modelling Program EUSES 2.1 calculates a low Koc of 65 L/kg (Chemical class for Koc QSAR Alcohols, organic acids). This estimated Koc is an indication of limited sorption of TPSA to solids and an OECD 106 Adsorption / Desoprtion Test is not warranted.


Based on the vapour pressure and CMC of TPSA EUSES 2.1 calculates a Henry's Law Constant (HLC) of 5.1 Pa*m3/mol at 12 deg C or dimensionless 2.1*E-03 m3/m3.
