	~~==Chemical Structure==~~		[[File:Polysorbate_20.png\|thumb\|right\|200px\|Chemical structure of Polysorbate 20]]
	~~Polysorbate 20 is a~~ [[~~polyoxyethylene]] derivative~~ of ~~sorbitan monolaurate. The number~~ 20 ~~in its name refers to the total number of [[oxyethylene~~]] ~~groups found in the molecule. The chemical formula of Polysorbate 20 is C58H114O26.~~

	~~==Production==~~		'''Polysorbate 20''', also known as '''Tween 20''', is a nonionic surfactant and emulsifier derived from polyethoxylated sorbitan and lauric acid. It is commonly used in the formulation of pharmaceuticals, cosmetics, and food products due to its ability to stabilize emulsions and enhance solubility.
	Polysorbate 20 ~~is produced by the ethoxylation of sorbitan~~, ~~which~~ is derived from ~~the [[dehydration]] of [[sorbitol]]~~. ~~This~~ is ~~followed by~~ the ~~esterification with lauric acid~~, ~~a [[fatty acid]] commonly found in coconut~~ and ~~palm kernel oils~~.

	==~~Uses~~==		== Chemical Properties ==
	Polysorbate 20 is widely used in the food and cosmetics industries due to its emulsifying properties. It helps to mix oil and water, preventing them from separating. In the food industry, it is used as an emulsifier in ice creams, baked goods, and salad dressings. In cosmetics, it is used in lotions, creams, and makeup products.

	~~==Safety==~~		Polysorbate 20 is a [[polyoxyethylene]] derivative of [[sorbitan monolaurate]]. It is characterized by its hydrophilic and lipophilic balance, which allows it to act as an effective emulsifier. The chemical formula of Polysorbate 20 is C<sub>58</sub>H<sub>114</sub>O<sub>26</sub>.
	Polysorbate 20 is ~~generally considered safe for use in foods~~ and ~~cosmetics. However~~, it ~~can cause skin irritation in some individuals, especially when used in high concentrations~~. ~~It is recommended to perform a patch test before using products containing~~ Polysorbate 20.

	==~~Regulation~~==		== Applications ==
	In the ~~United States~~, Polysorbate 20 is ~~regulated by~~ the [[~~Food~~ and ~~Drug Administration~~]] ~~(FDA)~~. It is ~~listed~~ as a food ~~additive that~~ is generally recognized as safe (GRAS). ~~In the European Union~~, it is ~~approved for use~~ in ~~food under the E number E432~~.
			=== Pharmaceuticals ===

			In the pharmaceutical industry, Polysorbate 20 is used as an excipient in the formulation of [[injectable drugs]], [[vaccines]], and [[biopharmaceuticals]]. It helps to improve the solubility of active pharmaceutical ingredients and stabilize protein formulations.

			=== Cosmetics ===

			Polysorbate 20 is widely used in [[cosmetic]] products such as [[creams]], [[lotions]], and [[shampoos]]. It acts as an emulsifier, helping to blend oil and water-based ingredients, and as a solubilizer for essential oils and fragrances.

			=== Food Industry ===

			In the food industry, Polysorbate 20 is used as an [[emulsifier]] in products like [[ice cream]], [[salad dressings]], and [[sauces]]. It helps to maintain the texture and consistency of these products by preventing the separation of oil and water phases.

			== Safety and Regulation ==

			Polysorbate 20 is generally recognized as safe (GRAS) by the [[Food and Drug Administration]] (FDA) for use in food products. However, it is important to adhere to regulatory guidelines regarding its concentration and usage in various applications.
