Fig. 2From: A comparison of log Kow (n-octanol–water partition coefficient) values for non-ionic, anionic, cationic and amphoteric surfactants determined using predictions and experimental methodsSlow-stirring vs solubility ratio log Kow values for all surfactant classes: non-ionic (blue cross), anionic (green triangle), cationic (blue diamond) and amphoteric (red square) [R2 for the amphoterics is omitted since there are only 2 points] [CMC determined using the surface tension method (OECD 115)]Back to article page
