What is Polysorbate 80?
Polysorbate 80 is a nonionic surfactant used for solubilization, dispersion, and emulsion support with comparatively lipophilic oils.
Formulation behavior
How it works inside a formula
Run a solubilizer-to-oil ratio screen and monitor color, odor, oxidation, foam, preservation, and clouding across temperature cycles.
