Polysorbate 60 (commonly known as Tween 60) is a nonionic surfactant and emulsifier derived from sorbitan and fatty acids. It is widely used in pharmaceuticals, food products, and cosmetics to stabilize emulsions and improve texture.
🏭⚗️ Production
Polysorbate 60 is produced by the ethoxylation of sorbitan, which is derived from sorbitol, followed by esterification with stearic acid. The manufacturing process involves controlling the degree of ethoxylation to achieve the desired hydrophilic-lipophilic balance.
🔬 Properties
Polysorbate 60 is a viscous, pale yellow to amber liquid or semi-solid. It is soluble in water and alcohols and functions effectively as an emulsifier by reducing surface tension between oil and water phases. It is stable under normal storage conditions and non-toxic.
🧪 Applications
• Used in food products as an emulsifier and stabilizer (often in baked goods and ice creams).
• Employed in pharmaceuticals to enhance solubility of active ingredients.
• Commonly used in cosmetics and personal care products such as lotions and creams for texture improvement.
• Utilized in industrial applications including detergents and emulsions.
