Additional information

Sodium 2 –butoxyethyl sulfate (CAS No. 67656 -24 -0) is characterized by a water solubility of > 2054 g/L, a low vapour pressure of < 0.001 Pa and a partition coefficient of < -2.7. Since the partition coefficient was below the trigger value of 3 the substance can be expected to have a low potential for adsorption. Based on these physicochemical properties the substance is not expected to evaporate into atmosphere or retain in the soil and sediment compartment. Therefore under environmental conditions the substance would mainly distribute into the water compartment.
