Polysorbate 20 USP/NF is a polysorbate-type nonionic surfactant used in many commercial and household products. It is composed of 20 repeated units of polyethylene glycol via ethoxylation. Polysorbate 20 USP/NF is a wetting agent, as well as washing agent, stabilizer and solubilizer in food products, laboratory assays and industrial applications. It is also an excipient that stabilizes emulsions and suspensions and lubricant in ophthalmic solutions. Polysorbate 20 USP/NF is used by philatelists to remove stamps from envelopes and to remove residues from stamps, without harming the stamp itself. Polysorbate 20 USP/NF is also used as wetting agent in rubber balers in the elastomer industry. Polysorbate 20 has been used as a shape directing agent to synthesize spheroidal magnetite nanoassemblies.

USPâ??NF is a combination of two compendia, the United States Pharmacopeia (USP) and the National Formulary (NF).
