Description of key information
The soil adsorption/desorption coefficient (log Koc) of 2-MBA was calculated to be 2.45± 0.03 based on the experimental log Kow of 2.90 ± 0.07 using the equation from European Chemicals Bureau: Technical Guidance Document on Risk Assessment, Chapter 4, 'Acetanilides, carbamates, esters, phenylureas, phosphates, triazines, triazoles, uracils'.
Key value for chemical safety assessment
Additional information
The soil adsorption/desorption coefficient (log Koc) of 2-MBA was calculated to be 2.45± 0.03 based on the experimental log Kow of 2.90 ± 0.07 using the equation from European Chemicals Bureau: Technical Guidance Document on Risk Assessment, Chapter 4, 'Acetanilides, carbamates, esters, phenylureas, phosphates, triazines, triazoles, uracils'. For comparison purposes, butyl acrylate has an experimental log Kow of 2.38 and an experimental Koc of 40 -148. Using the same Koc calculation above, butyl acrylate has an estimated Koc of 162. Based on this read-across information the calculated log Koc of 2-MBA is considered reliable.
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.
