XPO-5 (triphenylethylphenol polyoxyethylene ether ammonium sulfate) is a light yellow to brownish yellow transparent viscous liquid anionic surfactant. With its outstanding emulsifying capacity, acid-alkali resistance, and hard water tolerance, it plays a key role in various industrial fields. This product has low toxicity, no skin irritation, and is readily biodegradable (OECD 301B test, 28-day degradation rate > 70%), combining high performance with environmental friendliness.
Its core functions are reflected in four aspects: as an efficient emulsifier, it stably disperses oily active ingredients in water-based systems; as a wetting agent, it significantly reduces liquid surface tension and enhances permeability; as a dispersant, it prevents agglomeration and settling of solid particles; as a detergency component, it provides excellent emulsifying and cleaning capabilities. These properties make it a preferred auxiliary agent for formulators in demanding systems.

1. Pesticide Emulsifier (Core Application)
In pesticide formulations, it serves as a highly efficient emulsifier to promote stable dispersion of oily active ingredients (such as emulsifiable concentrates, microemulsions, and oil-in-water emulsions) in water-based systems, ensuring uniformity of the spray solution and significantly enhancing field application efficacy. Its hard water and acid-alkali resistance make it suitable for various water quality conditions and complex formulation systems.
2. Emulsion Polymerization Emulsifier
Used in emulsion polymerization systems (e.g., acrylates, styrene-acrylate copolymers), it effectively emulsifies monomers and stabilizes the resulting latex particles, helping to precisely control the particle size distribution of the polymer and improving the stability, film-forming ability, and overall performance of the final emulsion product.
3. Textile Auxiliary
Acts as a multifunctional auxiliary in textile processing. In pretreatment processes, it serves as an efficient wetting agent to rapidly and uniformly wet fibers; in dyeing processes, it acts as a penetrant and leveling agent, improving dye penetration and color uniformity, and reducing color differences.
4. Industrial Detergent
As a key surfactant component in industrial cleaning formulations, it provides excellent emulsifying and detergency capabilities, suitable for heavy-duty cleaning scenarios such as metal degreasing and hard surface cleaning, especially outstanding in removing oily soiling.
