Description of key information
The determination of adsorption/desorption of charcoal was performed according to OECD Guidelines for testing chemicals, testing gyidance No. 121.
The log Koc of the test item charcoal is stated as <1.5.
Key value for chemical safety assessment
- Koc at 20 °C:
- 31.6
Additional information
Two studies were performed to estimate the adsorption/desorption of charcoal according to OECD Guidelines for testing chemicals, testing gyidance No. 121.
The first one on a sample of charcoal with C-Fix = 80.5 % shows that the The log Koc of the test item charcoal is stated as <1.5.
The second on a sample of charcoal with C-Fix = 78.55 % shows that due to the limited solubility of the test item no chromatographic peak was detectable in the test item injection.
As a result the log Koc of the test item charcoal is stated as <1.5.
[LogKoc: 1.5]
