Polysorbate-65

What is Polysorbate-65?

Polysorbate 65 is a synthetic surfactant produced by ethoxylating sorbitan tristearate, a derivative of sorbitol and stearic acid from vegetable or animal fats. This creates a molecule with hydrophilic polyoxyethylene chains and lipophilic fatty acid portions, enabling it to act at oil-water interfaces. In cosmetics, it appears in lotions, creams, shampoos, and makeup removers, typically at low levels. As an emulsifier, it forms protective films around oil droplets to prevent separation, ensuring product stability and even texture. Its surfactant properties reduce surface tension, aiding in dirt removal and foam formation during cleansing. This dual functionality makes it valuable in water-based formulations needing to incorporate oils without instability.
