Product Overview

Polysorbates are non-ionic surfactants widely used as pharmaceutical excipients due to their excellent emulsifying, solubilizing, wetting, and stabilizing properties. Polysorbate 20, 40, 60, and 80 differ in fatty acid composition, enabling formulators to select the appropriate grade based on HLB value, solubilization strength, and formulation requirements. Polysorbates are extensively used in pharmaceutical, biopharmaceutical, nutraceutical, cosmetic, and food applications.
