Description of key information
Additional information
In a study conducted in accordance with OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and Sewage Sludge), multiple peaks were observed in test chromatograam produced in the study, many of which are considered insignificant to the test item (i.e. <1 % of overall peak area). Thus the given range of Koc reported in Drake (2001) is perhaps misleading with respect to the potential adsorption of the sub stance to soil and sewage sludge. The major peaks in this study occured at 3.3, 3.5 and 3.9 minutes, indicating a log Koc range of -0.5 to 1.34 which is more representative of the substance tested. Therefore a Koc of 21.88 and a log Koc of 1.34 have been presented as values for use in the chemical safety assessment.
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.
