Applications of 57-09-0
| Industry | Application | Process |
|---|---|---|
| Personal Care | Used as a cationic surfactant to impart conditioning and antistatic properties in shampoos and conditioners | Dissolved in water at ambient temperature; incorporated into the formulation system after compounding with other surfactants |
| Textile Dyeing & Finishing | Used as a softener, antistatic agent, and dyeing auxiliary to improve fiber hand feel and enhance uniform dye adsorption | Applied to fabrics during dyeing or finishing at 40–60 °C, using a bath concentration of 0.1–0.5% (on weight of fabric) |
| Water Treatment | Used as a biocide and algaecide to control bacteria, algae, and biological slime in recirculating cooling water systems | Dosed into the water system at 5–50 mg/L; maintains stable biocidal activity within pH 6–9 |
| Biopharmaceuticals | Used as a phase separation promoter and membrane permeability modulator in nucleic acid extraction reagents | Serves as a key component in lysis reagents such as TRIzol, facilitating RNA separation from proteins and DNA |
| Nanomaterial Synthesis | Used as a micellar template and morphology-directing agent for synthesizing mesoporous silica (e.g., MCM-41) and gold/silver nanoparticles | During sol-gel processing, micelle structure and final nanostructure are jointly controlled by CTAB concentration (typically 2–10 mM) and temperature |
| Agricultural Chemicals | Used as an emulsifier and synergist for hydrophobic pesticides to improve their dispersion stability in aqueous media | Formulated with organophosphorus or pyrethroid insecticides to produce thermodynamically stable microemulsions or emulsifiable concentrates (EW) |
| Analytical Chemistry | Used as a mobile phase modifier in high-performance liquid chromatography (HPLC) to improve retention and peak shape for basic compounds | Added to acetonitrile/phosphate buffer mobile phases at 0.5–5 mM concentration for reversed-phase C18 columns |
