- other: pH not available
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The adsorption coefficient (Koc) of the test item has been determined to be less than 17.8, log10 Koc less than 1.25. These values indicate that the test item has very high mobility.
- Executive summary:
The determination was carried out using the HPLC screening method, designed to be compatible with Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001. The test system utilized a high performance liquid chromatograph. A commercially available cyanopropyl reverse phase HPLC column containing lipophilic and polar moieties was used. Based on the findings, the adsorption coefficient was determined as less than 17.8, log10 Koc less than 1.25. These values indicate that the test item has very high mobility.

Description of key information
The adsorption coefficient of FAT 21036/G was determined according to EU Method C.19 (Estimation of the Adsorption Coefficient (KOC) on Soil and Sewage Sludge Using High Performance Liquid Chromatography (HPLC)) and OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)). Based on the findings, the adsorption coefficient was determined as follows-
Less than 17.8, log10 Koc less than 1.25. These values indicate that the test item has very high mobility.
Key value for chemical safety assessment
- Koc at 20 °C:
- 17.8
