ALS is classified as an alkyl sulfate and is an anionic surfactant 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 around the highly polar water molecules at the surface-air interface.
Physically, it’s a light yellow liquid. May float or sink and mix with water. (USCG, 1999)
