Ammonium Lauryl Sulfate (AMS)

Ammonium lauryl sulfate (AMS) is a surfactant, or a chemical which is used to interrupt the surface tension of water to allow wetting (increased penetration into materials it contacts) and foaming. Surfactants are the key ingredients in soaps, shampoos and non-personal cleaning agents. Since AMS is generally considered to be nonhazardous, it is also a permitted residue in foodstuffs. (As a wetting agent used to promote optimal coverage of herbicides, it will remain in small amounts on marketable fruits and vegetables.)

Ammonium lauryl sulfate is an excellent surfactant for use in acidic shampoos and other personal care formulations such as hand soaps and bath products. It can also be used in many detergent applications. It has an excellent viscosity response when formulated correctly with alkanolamides and amphoterics, and it generates large quantities of foam. Since it is a high foaming product, it can be used in rug and upholstery shampoos. Ammonium lauryl sulfate will give off an ammonia odor when the pH is alkaline.
