Sorbitan monooleate (commercially: Span® 80; Croda International PLC) is a nonionic surfactant and emulsifier widely used in various industries, including food, pharmaceuticals, and cosmetics. It is a sorbitan ester produced by the esterification of sorbitan with oleic acid, resulting in a light yellow, viscous liquid that is insoluble in ...
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products.. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone.

Polysorbate 20 is used by philatelists to remove stamps from envelopes and to remove residues from stamps, without harming the stamp itself. Polysorbate 20 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. [5]
Fertilizers are usually labeled with three numbers, as in 18-20-10, indicating the relative content of the primary macronutrients nitrogen (N), phosphorus (P), and potassium (K), respectively. More precisely, the first number ("N value") is the percentage of elemental nitrogen by weight in the fertilizer; that is, the mass fraction of nitrogen ...
DOTAP is a cationic surfactant and is able to form stable cationic liposomes in solution, these readily absorb DNA and other negatively charged organic compounds. The DNA laden liposomes can then be added directly to cell culture medium, where they will combine with the cell membrane and release their payload into the cell.
