Tween T-80 (Polyoxyethylene (20) sorbitan monooleate) is a classic nonionic surfactant with an HLB value of approximately 15.0. It is a hydrophilic emulsifier, particularly suitable for O/W (oil-in-water) emulsion systems. With excellent hydrophilic-lipophilic balance and broad-spectrum chemical compatibility, Tween T-80 maintains outstanding stability in acidic, alkaline, and hard water environments. It can be well compounded with both ionic and nonionic auxiliaries, making it one of the most widely used surfactants across industries.
In the pharmaceutical field, Tween T-80 is used as an efficient solubilizer for poorly soluble drugs and as an emulsifier for injections, oral solutions, and topical ointments, significantly improving the bioavailability and formulation stability of active pharmaceutical ingredients. In the food industry, it serves as an emulsifier and stabilizer for products such as ice cream, baking oils, and beverages, enhancing texture, consistency, and shelf life. In cosmetics and personal care, Tween T-80 performs emulsification and solubilization functions in creams, lotions, makeup removers, and perfumes, helping to uniformly disperse oily ingredients and fragrances while providing a refreshing skin feel.
In industrial fields, Tween T-80 also excels: in textile processing, it acts as an antistatic agent and softener component to reduce static electricity accumulation in synthetic fibers; in water-based coatings and inks, it serves as a pigment dispersant and emulsion polymerization emulsifier; in pesticide formulations, it functions as an emulsifier for emulsifiable concentrates and a tank-mix spreader to enhance spreading and penetration; in petroleum drilling fluids, it acts as an emulsifier to ensure system stability under extreme conditions; in daily chemical cleaners, it is used to solubilize fragrances and oils, improving detergency and product transparency.

As an O/W emulsifier, Tween T-80 is often compounded with Span series (e.g., Span S-80) to achieve better emulsification effects. In practical formulations, it is recommended to adjust the ratio with Span emulsifiers based on the HLB value requirement of the target system. For water-based coatings and inks, it is recommended to add it during the pigment grinding stage for optimal wetting and dispersion. In pesticide emulsifiable concentrate formulations, the recommended addition amount is 8%-15% of the active ingredient content (specific adjustment based on the characteristics of the active ingredient). For pharmaceutical and food grade applications, product specifications meeting relevant pharmacopoeia standards (e.g., ChP, USP, EP) should be selected.
