1.High-Foaming Anionic Surfactant: A C12 alkyl tail paired with a sulfate head group lowers surface tension and drives foam, wetting and emulsifying performance, which is why it is a standard base for shampoos, toothpaste, liquid detergents and hard-surface cleaners.
2.Emulsifier For Emulsion Polymerization: It serves as the emulsifier in emulsion polymerization of acrylic, styrene-acrylic, vinyl acetate and EVA monomer systems, where it stabilises the droplets and latex particles that form the final polymer dispersion.
3.Electroplating Bath Additive: In nickel and zinc plating it lowers surface tension at the liquid-solid interface and forms microemulsions, a property that plating shops rely on to keep their electrolyte baths working uniformly.
4.Textile, Firefighting And Oral Care: It is also used as a textile auxiliary, as a foaming agent in toothpaste and as the foam base in mine fire-extinguishing agents, so one product family covers several downstream formulation lines.
5.Laboratory And Research Reagent: Its ability to solubilise lipid membranes makes it the standard reagent for protein separation by SDS-PAGE and for preparing subcellular fractions, keeping it in steady demand from biotech and analytical laboratories.
