Applicant's summary and conclusion
- Conclusions:
- It is concluded that the test item charcoal (Probe 3: C-Fix = 88.7%) has a log POW of < 0.3 -1.474. The result is related to the used charcoal extract (charcoal (Probe 3: C-Fix = 88.7%) with a nominal concentration of 224360 mg/L in methanol/water (75/25 % v/v) under the testing conditions (temperature = 25+1°C, pH = 5.5) used.
