XPO-5 (tristyrylphenol polyoxyethylene ether ammonium sulfate salt) is an anionic surfactant. The product itself is non-flammable and non-explosive, and it has excellent chemical stability under recommended storage conditions. To ensure product performance does not deteriorate, special attention should be paid to three key aspects during storage: moisture protection, sealing, and temperature control. The product appears as a light yellow to brownish yellow transparent viscous liquid. Improper storage may cause color darkening or stratification, affecting subsequent usage.
As an ammonium sulfate salt surfactant, XPO-5 is sensitive to moisture. Absorption of moisture may reduce the concentration of active ingredients. It should also be stored separately from incompatible substances such as strong oxidizers, strong acids, and strong alkalis, as contact with these may cause side reactions, damage its anionic structure, and reduce core properties such as emulsification and dispersion. It is recommended to follow the "first-in, first-out" inventory management principle to ensure the product is used within the optimal period.
Regarding shelf life: The database does not currently list specific shelf life data for this product. According to industry practice for similar anionic polyoxyethylene ether sulfate surfactants, under strict adherence to recommended storage conditions (sealed, cool, dry), the typical shelf life of XPO-5 is generally 12 to 24 months. Users are advised to refer to the expiration date indicated on the product packaging label or Certificate of Analysis (COA) and regularly inspect the appearance and performance of stored products.

Before using XPO-5, check whether the product appearance is normal (light yellow to brownish yellow transparent viscous liquid, without obvious stratification or precipitation). Seal the container immediately after each withdrawal to minimize product exposure to air. If the product is used in fields with stringent performance requirements such as pesticide emulsifiers or emulsion polymerization, it is recommended to use within 6 months after opening, or conduct small-scale tests to verify that emulsification and dispersion effects meet standards before use.
