XPO-5 (Tristyrylphenol Ethoxylate Sulfate Ammonium Salt) is an anionic surfactant prepared by sulfation reaction of Tristyrylphenol Ethoxylate as an intermediate, followed by neutralization with ammonium salt. Its molecular structure consists of three core groups: the hydrophobic end is Tristyrylphenol, providing excellent lipophilicity and interfacial adsorption capacity; the middle chain is Polyoxyethylene ether (EO chain), imparting certain hydrophilicity and flexibility to the product; the hydrophilic end is Ammonium sulfate group (-OSO₃⁻NH₄⁺), making it exhibit anionic properties after dissociation in water.
From the product specifications, XPO-5 appears as a light yellow to brownish yellow transparent viscous liquid at room temperature, and its ionic type is clearly anionic. As an industrial-grade surfactant product, its main component content is usually measured by the active matter content (solid content). For the specific percentage of the active ingredient, it is recommended to refer to the product quality inspection report or COA (Certificate of Analysis) provided by Guoli Chemical. The database does not currently include the precise percentage data of the main component of this product.

Due to its unique molecular structure, XPO-5 exhibits excellent emulsifying, wetting, and dispersing properties, especially suitable for complex formulation systems requiring high resistance to acids, alkalis, and hard water. In the field of pesticide emulsifiers, it effectively promotes the stable dispersion of oily active ingredients in water-based systems, enhancing the uniformity of the spray solution; as a main emulsifier in emulsion polymerization, it helps control the particle size and distribution of latex particles; it also performs well in textile auxiliaries and industrial detergents.
