Validity criteria fulfilled:
not applicable
Conclusions:
log Koc: 4.06 ± 0.45 (calculation method given in TGD)
Executive summary:

The organic carbon normalized partition coefficient (log Koc) of C4 sulfonamido methacrylate was calculated from the log Kow value of 4.89 using an equation from European Chemicals Bureau: Technical Guidance Document on Risk Assessment, Chapter 4.3: Soil and Sediment Sorption. Per this section, the equation used is applicable to all chemicals with C, H, F, Cl, Br, and I atoms. The calculated value of log Koc was 4.06 ± 0.45.

The log Koc was calculated using an accepted method. It is considered reliable with restrictions and is suitable for Risk Assessment, Classification & Labelling, and PBT Analysis.
