- Details on results:
- As the test item is a UVCB, the HPLC method was used.
As the test item consisted of ammonium salts of dicarboxylic acids, testing was performed at approximately neutral pH with the test item being tested in its ionised form.
As a wavelength of 210 nm was used for the sample injections, the test item’s counter-ion, ammonium, would not have been detected. Therefore, the sample peaks were considered to be due to the ionized, dicarboxylic acid components of the test item.
Using EpiSuite v4.11, © United States Environmental Protection Agency (US EPA), an experimental log10 Pow value -1.38 was given for ammonia. Furthermore, ammonia is an inorganic substance. Therefore, the requirement for assessment of the partition coefficient for the ammonium counter-ion was considered to be unnecessary. - Conclusions:
- The partition coefficient of the test item at pH 6.7 has been determined to be in the range less than 2.0 to 3.29 x 10(+4), log10 Pow in the range less than 0.3 to 4.52. Using area normalization, 22.0% of the test item gave a log10 Pow value greater than 3.0.
