Adsorption / desorption :

Soil Adsorption Coefficient i.e Koc value of sodium 2-(2-dodecyloxyethoxy) ethyl sulphate was estimated as 2111 L/kg by means of MCI method. This indicates that sodium 2-(2-dodecyloxyethoxy) ethyl sulphate will have a moderate tendency of sorption to soil and have slow migration potential to groundwater.This koc value is equivalent to 1688.8 (log koc as 3.23) at 20 deg C.

Henry's Law constant :

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. Henrys Law Constant of sodium 2-(2-dodecyloxyethoxy) ethyl sulphate at 25 deg C is 0.00000451 Pa m³/mol.
