Applicant's summary and conclusion

Executive summary:

The partition coefficient study was performed according to the OECD 117.

The chromatogram of the test substance solution showed 4 peaks.

The first three peaks lie within the dead time of the method and not within the range of log POWs of the reference substances. Therefore, the corresponding logP are stated as < 0.3 for peaks 1, 2, and 3. Using the correlation log k / logP, the logP of peak 4 of the test substance EXTRACT OF ALLIUM CEPA (AMARYLLIDACEAE) BULB AND CITRUS LIMON (RUTACEAE) PULP AND SODIUM CHLORIDE was calculated as 0.715 ± 0.000(mean ± standard deviation),determined at 25 ± 0.5°C and at pH 7, measured with pH paper.
