Applicant's summary and conclusion

Conclusions:
Partition co-efficient: Log Kow: 0.14 at 32 Deg C

Executive summary:

The principle of the method being ratio of concentrations of a compound in the two phases of a mixture of Octanol-Water at equilibrium, 4-sulphoanthranilic acid was estimated using the US EPA shake flask method. The log octanol/water partition coefficient (log Kow) of the substance was observed to be 0.14 at 32°C.
