Ammonium lauryl sulfate (ALS) is the INCI name and common name for ammonium dodecyl sulfate (CH₃(CH₂)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. This salt is classified as a sulfate ester. It is made from coconut or palm kernel oil for use primarily in shampoos and body-wash as a foaming agent.^[1][2] Lauryl sulfates are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.
