Polysorbate 80 — Tween 80 / CAS 9005-65-6

Description

1. Product Overview

Polysorbate 80 (Tween 80) is a non-ionic surfactant and emulsifying agent derived from sorbitol, oleic acid, and ethoxylation processes, widely used to stabilize and improve the performance of industrial and consumer formulations. It provides excellent emulsification, solubilization, dispersion, and wetting properties across pharmaceutical, food, cosmetic, and specialty chemical applications. Its high compatibility with aqueous systems and active ingredients makes it a critical multifunctional ingredient for advanced formulation technologies. As global demand grows for stable, high-performance formulations, Polysorbate 80 remains a strategically important ingredient in regulated and high-value industries.
