Description of key information

Henry's Law constant of threonine as the main constituent of Biofert plusz was calculated using EPIWIN (v4.0), HENRYWIN (v3.20). The calculation yielded a value of  7.34E-009 Pa x m3/mole.

Key value for chemical safety assessment

Additional information

Henry's Law constant of threonine as the main constituent of Biofert plusz was calculated using EPIWIN (v4.0), HENRYWIN (v3.20). The calculation of Henry's Law constant according to the equation H=vp/ws yielded a value of 7.34E-009 Pax m3/mole using an estimated water solubility of 2.79e+005 mg/l and a vapour pressure of 7.88E-009 mm Hg. Based on the result, threonine can be considered as practically non-volatile from aqueous solution.
