- Value:
- 4.82 dimensionless
- Details on results (HPLC method):
- The adsorption coefficient Koc was determined based on a calibration curve using 8 reference items. The capacity factors k’ were calculated from the dead time and retention times of the reference substances. The log k’ data of the reference substances were plotted against their log Koc values.
- Validity criteria fulfilled:
- yes
- Conclusions:
- In the course of this study the adsorption coefficient (Koc) of Reaction products of IPDA with bisphenol A diglycidylether (BADGE) was estimated, using high performance liquid chromatography.
The log Koc of Reaction products of IPDA with bisphenol A diglycidylether (BADGE) was found to be 4.82.
The quality criteria were met, as values of log Koc derived from individual measurements fell within a range of ± 0.25 log units and the correlation coefficient R was >0.95.
The estimated log Koc: 4.82
The estimated Koc: 65860 - Executive summary:
Estimation of the Adsorption Coefficient (Koc) of Reaction products of IPDA with bisphenol A diglycidylether (BADGE)according to OECD 121 and EU method C.19 was performed. In the course of this study the adsorption coefficient (Koc) of Reaction products of IPDA with bisphenol A diglycidylether (BADGE) was estimated, using high performance liquid chromatography. The estimated log Koc is 4.82 and the estimated Koc is 65869, respectively.
