Polysorbate 80
Polysorbate 80 (CAS: 9005-65-6), also known as Tween 80, is a non-ionic surfactant produced by ethoxylating sorbitan monooleate with approximately 20 ethylene oxide units. This amber-colored, water-dispersible liquid combines a hydrophilic polyoxyethylene head with lipophilic oleate tails, giving it an excellent balance for emulsifying, solubilizing, and dispersing a wide range of hydrophobic substances in aqueous systems. It is one of the most widely used excipients in the pharmaceutical industry, stabilizing emulsions in injectable formulations and solubilizing lipophilic active ingredients in oral and topical products. In cosmetics and personal care it emulsifies creams, lotions, and serums while providing mild conditioning. The food industry relies on it as emulsifier E433 in dressings, ice cream, and baked goods to improve texture and prevent oil separation. With low irritation potential and strong regulatory acceptance, Polysorbate 80 remains a benchmark emulsifier across life-science and consumer industries.
– Pharmaceutical Formulations: Used as an emulsifier and solubilizer in injectables, oral liquids, and topical products to stabilize oil-in-water systems and dissolve lipophilic actives.
– Cosmetics and Personal Care: Incorporated into creams, lotions, shampoos, and serums to create stable emulsions, improve texture, and enhance ingredient dispersion.
– Food Industry Applications: Approved as emulsifier E433 in ice cream, salad dressings, sauces, and baked goods to prevent phase separation and improve mouthfeel.
– Industrial Emulsions and Dispersions: Employed in agrochemical emulsifiable concentrates, textile processing, and pigment dispersions to stabilize multi-phase systems.
