They are used in cosmetics to solubilize essential oils into water-based products, pharmaceuticals, detergents, paints, and plastic applications. These Polysorbate surfactants consist primarily of oleic, stearic, or lauric fatty acid esters. Polysorbates improve the texture and stability of formulations by enhancing the mixing of oil and water phases. They are also known for their low toxicity and biocompatibility, making them ideal for use in personal care and pharmaceutical products. Additionally, these surfactants help increase the shelf life of products by preventing ingredient separation.
