Sodium lauryl sulfate is a surfactant, which means a molecule that has ampiphilic properties. This means the sulfate head group (shown by the pink shading in the diagram below) is hydrophilic and water soluble, while the 12-carbon-long chain is hydrophobic and water insoluble. It is an anionic surfactant as defined by the sulfate head group ...

Sodium lauryl xyethylene sulfate's production and use as a surfactant may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 1.8X10-16 mm Hg at 25 °C indicates sodium lauryl xyethylene sulfate will exist solely in the particulate phase in the ambient atmosphere.
