Description of key information
A log Koc of -3,3852 and a Henry’s Law constant of 2.87E-07 Pa x m³ x mol-1 were calculated.
Additional information
Adsorption/desorption
An OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) study was performed to determine the soil adsorption coefficient (Koc) of KMPS tripe salt. The Koc was determined to be < 18 at 20 °C and the log Koc was < 1.25.
To get a more precise result the log Koc was further calculated by a QSAR approach. Therefore, the log Koc was calculated by KOCWIN v2.00 based on the calculated log Kow (-3.9) of the substance. The following formula is used: Log Koc = 0.8679 * logKow - 0.0004, resulting in a log Koc of -3.3852.
Henry`s Law constant
Calculated using the vapour pressure (1.7E-04 Pa, see section 4.6), the molecular mass (614.76 g/mol) and the solubility in water (364 g/L, see section 4.8) by using the formula:
HLC = vapour pressure * molecular mass / water solubility = 2.87E-07 Pa x m³ x mol-1
Therefore KMPS triple salt is not volatile.
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.
