Ammonium lauryl sulfate is the common name for ammonium dodecyl sulfate 10CH2OSO3NH4]. The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates dissolution of both polar and non-polar materials. ALS is classified as a sulfate ester. It is found primarily in shampoos and body-wash as a foaming agent./ Lauryl sulfates are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.
