Applicant's summary and conclusion
- Conclusions:
- Depending on the calculation method used, the log Koc was found to be -1.3040 (based on log Kow) or 1.00 (based on MCI method).
- Executive summary:
The log Koc was calculated by EpiSuite's KOCWIN model.
The suitability of the model was assessed and it was concluded that L-histidine is considered to be inside the applicability domain of the EpiSuite KOCWIN model.
Depending on the calculation method used, the log Koc was found to be -1.3040 (based on log Kow) or 1.00 (based on MCI method).
