Polysorbates
Polysorbates are a class of nonionic surfactants derived from sorbitol and fatty acids, commonly used as emulsifiers, solubilizers, and dispersing agents in a wide range of industries. They improve the mixing of oil and water phases, stabilize emulsions, and enhance the texture and consistency of formulations. Polysorbates are widely used in pharmaceuticals, cosmetics, food products, and industrial applications due to their biocompatibility, low toxicity, and effectiveness at low concentrations.
