Description of key information

A study was performed to estimate the adsorption coefficient (Koc)  of 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoate by HPLC. The method followed is amongst those described in Commission Regulation (EC) No. 440/2008 (Method C19) and the OECD Guidelines for the Testing of Chemicals (Method 121). 3-hydroxy-1,1-dimethylbutyl 2-ethyl-2-methylheptaneperoxoate  was determined to have a log Koc value of 3.3 (equivalent Koc= 2100).
