Additional information

This study “Estimation of the Adsorption Coefficient (Koc) of bis(2,3-epoxypropyl)cyclohexane-1,2-dicarboxylate using High Performance Liquid Chromatography (HPLC), (GLP compliant study based on OECD Guideline for Testing of Chemicals, Guideline No. 121: ”Estimation of the Adsorption Coefficient on Soil and on Sewage sludge using High Performance Liquid Chromatography (HPLC)”, 2001 and Commission Regulation (EC) No 440/2008, Annex, C.19: “Estimation of the Adsorption Coefficient on Soil and on Sewage sludge using High Performance Liquid Chromatography (HPLC)”, 2008), Author: E. Baltussen, Study Completion Date: March 22, 2012, is classified acceptable and satisfies the guideline OECD 121 requirements for adsorption desorption studies.

The Koc and log Koc values of the main component of the test substance at neutral pH were 61 and 1.79 respectively. Several minor components with log Koc values ranging from < 0.45 to 3.10 were observed.
