Sodium Lauryl Sulphate (E487): What It Is and Is It Safe?
Sodium lauryl sulphate, also called sodium dodecyl sulfate, is an anionic detergent used in food as a whipping agent for egg products and marshmallows and as an emulsifier or wetting agent, at low permitted levels. As a surfactant it can irritate the gastrointestinal mucosa at higher concentrations, so its food uses are tightly restricted. The US FDA authorises specific uses under 21 CFR 172.822.
