polysorbitans

Polysorbitans are a group of non-ionic surfactants, which are compounds that lower the surface tension between two liquids, such as water and oil. They are derived from sorbitol, a sugar alcohol, and are commonly used in the food industry as emulsifiers. Emulsifiers help to stabilize mixtures of oil and water, preventing them from separating. Polysorbitans are often used in baked goods, dressings, and sauces to improve texture and prevent ingredients from separating.

Polysorbitans are generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and are widely used in various food products due to their versatility and effectiveness. They are typically identified by a number, such as polysorbate 20 or polysorbate 80, which indicates the average molecular weight of the compound. The number is derived from the average number of sorbitol units in the molecule.

Polysorbitans are also used in pharmaceuticals and cosmetics. In pharmaceuticals, they can be used to improve the solubility of drugs and to stabilize emulsions. In cosmetics, they are used as emulsifiers and stabilizers in creams, lotions, and other products. However, like all surfactants, polysorbitans can have potential environmental and health impacts, and their use should be carefully considered and regulated.
