Reference
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.
Description of key information
log Pow: -2 to -1.3
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.3
- at the temperature of:
- 23 °C
