Description of key information
The adsorption coefficient of the research material was determined to be < 17.8 with Log10 Koc < 1.25 (OECD 121 and EU Method C.19).
Additional information
Adsorption/desorption
The key determination was carried out using the HPLC screening method, designed to be compatible with Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001.
The test utilised a High Performance Liquid Chromatograph. A commercially available cyanopropyl reverse phase HPLC column containing lipophilic and polar moieties was used. The dead time was determined by measuring the retention time of formamide (purity quoted by supplier: 99.94%) at 615 mg/L in methanol. Solutions of reference standards were prepared in methanol and the test item (0.0536 g) was diluted to 100 mL with methanol:water (55:45 v/v) to give a concentration of 0.536 g/L.
The adsorption coefficient of the research material was determined to be < 17.8 with Log10 Koc < 1.25
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.
