The log BCF values of known peppermint oil constituents were estimated using the QSAR BCFBAF v 3.00. Log Kow estimates were calculated using the corresponding log Kow value estimated by KOWWIN (see chapter 4.7).

The range of log BCF values for the known constituents of peppermint oil was found to be 1.47 - 4.282 (BCF 30 – 19143). 66.5% of the NCS has a log BCF of 1.679 - 1.772 (BCF 48 – 59, menthone + L-menthol).
