XPO-5 (tristyrylphenol polyoxyethylene ether ammonium sulfate) belongs to the Guoli Chemical anionic surfactant product series, appearing as a light yellow to brownish yellow transparent viscous liquid. Its molecular structure features a tristyrylphenol hydrophobic backbone, with a polyoxyethylene ether chain introduced through sulfation and existing in ammonium salt form. This unique structure endows the product with excellent acid-alkali stability and hard water resistance, enabling it to maintain efficient and stable interfacial activity in complex industrial systems.
As a functional surfactant with balanced performance, XPO-5 combines the high emulsification efficiency of anionic surfactants with the hard water resistance advantage provided by the nonionic polyoxyethylene ether segment. It is widely used in various fields such as pesticide formulations, emulsion polymerization, textile processing, and industrial cleaning, especially suitable for water-based formulation systems with demanding emulsification stability requirements.

Pesticide Emulsifier: Used as an efficient emulsifier in pesticide formulations (e.g., emulsifiable concentrates, suspoemulsions, microemulsions), it promotes the stable dispersion of oily active ingredients in water-based systems, ensuring uniformity of the spray solution and field application effectiveness. Gradient tests are recommended based on the type of active ingredient and formulation to determine the optimal dosage.
Emulsion Polymerization Emulsifier: Used in emulsion polymerization systems such as acrylate and styrene-acrylate, it effectively emulsifies monomers and stabilizes the generated latex particles, helping to control polymer particle size distribution and improving the mechanical stability and electrolyte resistance of the final product.
Textile Auxiliary: Acts as a multifunctional auxiliary in pretreatment and dyeing processes, providing wetting, emulsifying, and dispersing functions, improving fiber treatment uniformity and dye penetration, suitable for processing cotton, polyester, and other synthetic fibers.
Industrial Detergents: Serves as a key surface-active component in industrial cleaning formulations such as metal degreasers and hard surface cleaners, offering excellent emulsifying and detergency capabilities, especially suitable for heavy-duty cleaning scenarios.
