Polysorbate 60, identified by CAS number 9005-67-8, is a versatile non-ionic surfactant and emulsifier widely utilized across various industrial sectors. Chemically, it is a polyoxyethylene derivative of sorbitan monostearate, characterized by its ability to stabilize oil-in-water emulsions. It typically appears as a lemon-colored to orange-colored waxy solid or paste, offering excellent solubility in water and compatibility with a broad range of other surfactants. Its stable chemical nature ensures consistent performance even when exposed to varying pH levels or electrolyte concentrations.
In industrial and research contexts, Polysorbate 60 is valued for its high Hydrophile-Lipophile Balance (HLB) value, which facilitates the creation of smooth, stable mixtures of otherwise immiscible liquids. Proper handling involves storing the material in a cool, dry environment to maintain its physical integrity. Its multi-functional properties as a wetting agent, dispersant, and solubilizer make it an indispensable component in complex formulations where texture and homogeneity are critical requirements.
