Sodium lauryl sulfate has good emulsifying and foaming properties, is water-soluble, biodegradable, alkali-resistant, hard-water-resistant, stable in aqueous solutions over a wide pH range, easy to synthesize, and inexpensive. It has been widely used in cosmetics, detergents, textiles, papermaking, lubrication, as well as pharmaceuticals, building materials, chemicals, and oil production. It can also be applied to basic research on the properties of cationic and anionic surfactant complex systems, micelle catalysis, and ordered molecular assemblies.
