Key result
Type:
log Pow
Partition coefficient:
>= -2 - <= -1.3
Temp.:
23 °C
Remarks on result:
other: pH not reported

The octanol solubility of Disodium 4-[1-methyl-2-[(1-oxooctadec-9-enyl)amino]ethyl] 2 -sulphonatosuccinate is < 0.5 g/L at room temperature (23 °C).

Taking the water solubility of the registered substance 10 – 50 g/L into account, this would corresponds to a log POW range of -1.3 to -2.

Conclusions:
log Pow: -2 to -1.3

Description of key information
