Applicant's summary and conclusion

Conclusions:
As a result of partition coefficient test, the logPow value of trimethyloctylammonium methyl
sulphate was determined as –1.86 and was within an acceptable range (-2 to 5) of logPow
specified by the OECD guideline. Also, the standard deviation was determined as ± 0.14 in
this study (Table 3).
