Koc at 20 °C:
91

Additional information

The adsorption test (Geffke_2005) performed according to OECD 121 and GLP was rated with RL=1 (reliable without restrictions) and used as key study. The estimated log Koc of SymWhite® 377 is 1.96. According to the McCall classification scheme of soil mobility potential, a Koc of 91 indicates that SymWhite® 377 has a high mobility in soil.

The temperature during measurement (column temperature) was 23°C.
