Additional information

The partition coefficient (n-octanol/water) of 1,1-bis(tert-butylperoxy)cyclohexane was assessed in accordance with OECD guideline no. 117, EU method A.8 and OPPTS 830.7570 guideline. In the course of this study the partition coefficient (Pow) of 1,1-bis(tert-butylperoxy)cyclohexane was determined using high performance liquid chromatography. The retention times of 1,1-bis(tert-butylperoxy)cyclohexane is higher than the last eluting standard (DDT), therefore an accurate value of logPow could not be given. The extrapolated log Pow value calculated for 1,1-bis(tert-butylperoxy)cyclohexane was 7.2.
