Applicant's summary and conclusion

Conclusions:
The partition coefficients (1-octanol / water) of the test item were: log Pow = -1.5 destilled water
Executive summary:

The partition coefficients 1-octanol / water of the test item at pH 2 and in distilled water at room temperature were determined according to the "shake flask method" described in EEC Test Guideline 92/69 A.8, OECD Test Guideline 107 and EPA Product Properties Test Guideline OPPTS 830.7550.
