Tween Series Surfactants | Polysorbate 20, 60, 80 Factory Supply
High-performance Nonionic Emulsifiers (600# & BY Series) for Pesticide EC & WP Formulations.
High-Hydrophilic Polysorbate Solutions (T-20 to T-80)
Kemaix Tween Series surfactants are essential hydrophilic non-ionic emulsifiers with HLB values ranging from 9.6 to 16.7. Often used in tandem with the Span series, these polysorbates provide superior O/W emulsification, solubilization, and dispersion. We focus on precise EO addition control to ensure each batch delivers consistent foaming and wetting properties, making them reliable for large-scale production in food, cosmetics, and agrochemicals.
Tween Series - Polysorbates
Performance & Characteristics
Performance:
Hydrophilic nonionic emulsifiers that are safe, non-toxic, and non-irritating. Depending on the type of fatty acid, a series of products is obtained with HLB values ranging from 9.6 to 16.7. These products are soluble or dispersible in water, alcohols, and other polar organic solvents, and exhibit excellent emulsifying, solubilizing, and stabilizing properties.
