Polysorbate 20

Index Polysorbate 20

Polysorbate 20 (common commercial brand names include Scattics, Alkest TW 20 and Tween 20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan before the addition of lauric acid. [1]

Cell membrane

The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space).

Denatured alcohol

Denatured alcohol, also called methylated spirit (methylated spirits in Australia and New Zealand) or denatured rectified spirit, is ethanol that has additives to make it poisonous, bad tasting, foul smelling or nauseating, to discourage recreational consumption.

Detergent

A detergent is a surfactant or a mixture of surfactants with cleaning properties in dilute solutions.

Elastomer

An elastomer is a polymer with viscoelasticity (i. e., both viscosity and elasticity) and very weak intermolecular forces, and generally low Young's modulus and high failure strain compared with other materials.

ELISA

The enzyme-linked immunosorbent assay (ELISA) is a test that uses antibodies and color change to identify a substance.

Emulsion

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable).

Ethoxylation

Ethoxylation is a chemical reaction in which ethylene oxide adds to a substrate.

Excipient

An excipient is a substance formulated alongside the active ingredient of a medication, included for the purpose of long-term stabilization, bulking up solid formulations that contain potent active ingredients in small amounts (thus often referred to as "bulking agents", "fillers", or "diluents"), or to confer a therapeutic enhancement on the active ingredient in the final dosage form, such as facilitating drug absorption, reducing viscosity, or enhancing solubility.

Immunoassay

An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes).

Lauric acid

Lauric acid or systematically, dodecanoic acid, is a saturated fatty acid with a 12-carbon atom chain, thus having many properties of medium chain fatty acids, is a white, powdery solid with a faint odor of bay oil or soap.

Lysis

Lysis (Greek λύσις lýsis, "a loosing" from λύειν lýein, "to unbind") refers to the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, "lytic") mechanisms that compromise its integrity.

Repeat unit

A repeat unit or repeating unit is a part of a polymer whose repetition would produce the complete polymer chain (except for the end-groups) by linking the repeat units together successively along the chain, like the beads of a necklace.
