Description of key information
Additional information
Adsorption / desorption
The QSAR determination of the carbon partition coefficient for tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.1 revealed values of 0.001756 L/kg (log Kow method) and 25.38 L/kg (MCI method). Both predicted values indicate no adsorption/desorption potential for the substance.
Henry's Law constant
The Henry's Law Constant (HLC) for tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate was predicted using the QSAR calculation of the Estimation Program Interface (EPI) Suite v4.1. Based on the Bond contribution methodology the HLC was estimated to be 1.21E-21 Pa*m³/mol indicating that the substance is essentially non-volatile from water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
