Coco fatty acids 2 -sulfoethyl ester, sodium salt was demonstrated to have a low to moderate tendency to adsorb to waste water treatment sludge. In an OECD 106 test the partitioning to sludges was measured and resulted in a Koc value of 1451 L/kg .

Coco fatty acids 2-sulfoethyl ester, sodium salt is readily biodegradable has a very low vapour pressure and the calculated Henry’s Law constant value indicates a low volatility. Level I calculations using a water solubility of 102 mg/L, a vapour pressure of 0.0015 and a log Kow of 4.116

to predict the partitioning to soil and sediment resulted in a distribution of 90% to soil, 7.8% to water and 2% to sediment. Therefore, it can be anticipated that if Coco fatty acids 2 -sulfoethyl ester, sodium salt is released to the environment, the fraction in the aqueous phase is immediately degraded and the minimal fraction which is not degraded will most likely partition to the soil and sediment.
