- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material:test item supplied by sponsor/91112Y
- Expiration date of the lot/batch:12 March 2021
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material:Ambient temperature (10~30oC)
- Stability under storage conditions:Stability (water, light, etc.)

- Key result
- Type:
- log Pow
- Partition coefficient:
- >= 5.7 - <= 8.6
- Temp.:
- 35 °C
- Remarks on result:
- other: pH is not available
- Type:
- log Pow
- Partition coefficient:
- 8.1
- Temp.:
- 35 °C
- Remarks on result:
- other: the weighted average logPow of main constitut
- Details on results:
- The test iem in HPLC spectrogram shows four peaks. The first two peaks are impurities, the last two are main constituents. The substance is a multi-constituent substance with two components, anf these two components are homologues, according to OECD117 guideline, the weight average logPow of main constituent is 8.1.
- Conclusions:
- LogPow values were calculated in the range of 5.7~8.6.
- Executive summary:
The partition coefficient of the test item has been determined as log P = 5.7~8.6 at 35°C according to OECD Guideline 117 (HPLC Method).
