Tween T-81 is a nonionic surfactant (Polyoxyethylene (5) sorbitan monooleate, CAS: 9005-65-6), with a moderate HLB value and prominent lipophilicity. In pesticide formulations, it can be combined with the Span series to flexibly adjust HLB for precise emulsification; in cosmetics, it serves as a water-in-oil (W/O) emulsifier, providing a fine texture; in metalworking fluids, it has dual functions of emulsification and boundary lubrication.
This product is an amber oily liquid, classified as GHS Eye Irritation Category 2 (H319). Protective goggles and gloves must be worn during handling. Storage temperature should be controlled at 5°C–30°C, avoiding freezing.
