Due to its excellent surface activity, sodium dodecyl sulfate plays a key role as an auxiliary agent in numerous industrial processes.
Textile Printing and Dyeing Industry: In the pretreatment and dyeing processes of textiles, it is used as a highly efficient penetrant and leveling agent. It can rapidly reduce the surface tension of the treatment solution, helping dyes and chemicals to penetrate quickly and evenly into the fiber, improving dyeing quality and efficiency. It is also used in post-washing processes.
Pharmaceutical and Cosmetic Industry: In addition to its role as a cleaning ingredient, it is used as an emulsifier in some ointments in pharmaceuticals; in cosmetics, it is used to prepare creams and lotions, helping the oil and aqueous phases to mix uniformly and maintain stability.
Emulsifier for Emulsion Polymerization: In the polymer chemistry industry, sodium dodecyl sulfate is a commonly used anionic emulsifier in the emulsion polymerization of monomers such as acrylates and styrene-butadiene, and is crucial for forming stable polymer emulsions with uniform particle size.
Metalworking and Cleaning: It is used as an auxiliary agent in some metalworking fluid formulations and also in the formulation of industrial equipment cleaning agents.
Other Special Uses
Fire Extinguisher Foaming Agents: It can be used as a foaming agent component in some foam fire extinguishers.
Pet Shampoos and Agricultural Adjuvants: Also utilizing its cleaning and foaming properties.
