Description of key information

The objective of this study was to determine the Adsorption Coefficient of the test item 10- UNDENECENOIC AClD applying the procedure described in the OECD Guideline 121 Adsorption Coefficient on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC). At the test conditions (HPLC), the adsorption coefficient of 10-UNDENECENOIC AClD was found to be log Koc = 2.84 (Koc = 691.83).

Additional information

The adsorption coefficient of 10-UNDENECENOIC AClD was found to be log Koc = 2.84 (Koc = 691.83) ( OECD Guideline 121 Adsorption - HPLC) . This result is close to the log Koc 2.77 of reference substance acetanilid, which represents the lower end of adsorbability capacity of the reference substances used. Therefore test item undecylenic acid can be considered as a less adsorptive substance.

[LogKoc: 2.84]
