Polysorbate 40 is a nonionic surfactant and emulsifier made by the ethoxylation of sorbitan monopalmitate. It is widely used in food, pharmaceutical, and cosmetic applications to stabilize emulsions, improve solubility of oils, and enhance product consistency. This ingredient is valued for its mildness, water solubility, and ability to act as both an emulsifier and dispersant. It helps in solubilizing flavors, essential oils, and active ingredients in aqueous systems.
