Applications:
Tween, also known as polysorbate, is a versatile nonionic surfactant and emulsifier.
In household and personal care products: it plays a key role in enhancing viscosity, boosting foam, and improving lubricity. As a result, it delivers superior emulsification, leaves products feeling gentler on the skin, ensures easier rinsing, and provides a smoother application experience.
In industrial field: polysorbate serves as an effective emulsifier, dispersant, and wetting agent. It is widely used in inks, coatings, adhesives, and similar products, where it significantly improves stability, flow, and adhesion.
