Polysorbates are a group of synthetic compounds commonly used as emulsifiers in food, cosmetics, and pharmaceuticals. They help mix oil and water, improving the texture and stability of products. The most well-known example is Polysorbate 80, which is often found in ice cream and salad dressings. These compounds are derived from sorbitol and fatty acids, making them effective in enhancing the delivery of active ingredients in various formulations. While generally recognized as safe by regulatory agencies, some individuals may experience sensitivities or allergic reactions to certain polysorbates.
