Quaternary ammonium salts are used as disinfectants, surfactants, fabric softeners, and as antistatic agents (e.g. in shampoos). In liquid fabric softeners, the chloride salts are often used. In dryer anticling strips, the sulfate salts are often used. Older aluminium electrolytic capacitors and spermicidal jellies also contain quaternary ...
Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me 4 N] + and consists of four methyl groups (−CH 3, denoted Me) attached to a central nitrogen atom. The cation is isoelectronic with neopentane (Me 4 C). It is positively-charged and can only be isolated in association with a counter-ion.
Quaternium-15 (systematic name: hexamethylenetetramine chloroallyl chloride) is a quaternary ammonium salt that has been used as a surfactant and preservative.It acts as an antimicrobial agent because it slowly releases formaldehyde, which is a preservative with biocidal properties.
The main application of fatty amines is for the production of the corresponding quaternary ammonium salts, which are used as fabric softeners and hair conditioners (e.g. Behentrimonium chloride). Fatty amines are also used in froth flotation, for the beneficiation of various ores. The amines bind to the surfaces of certain minerals allowing ...
Quaternary ammonium compounds are positively charged polyatomic ions of the structure NR 4 + with R being alkyl or aryl groups. The R groups may also be connected. The R groups may also be connected. Wikimedia Commons has media related to Quaternary ammonium compounds .
It is a quaternary ammonium salt, consisting of choline cations ([(CH 3) 3 NCH 2 CH 2 OH] +) and chloride anions (Cl −). It is a bifunctional compound, meaning, it contains both a quaternary ammonium functional group and a hydroxyl functional group. The anion of this salt, choline, occurs in nature in living beings.

Tetramethylammonium chloride is a major industrial chemical, being used widely as a chemical reagent [1] and also as a low-residue bactericide in such processes as hydrofracking. [2] In the laboratory, it has fewer synthetic chemical applications than quaternary ammonium salts containing longer N-alkyl substituents, which are used extensively ...
Tetraethylammonium (TEA) is a quaternary ammonium cation with the chemical formula [Et 4 N] +, consisting of four ethyl groups (−C 2 H 5, denoted Et) attached to a central nitrogen atom. It is a counterion used in the research laboratory to prepare lipophilic salts of inorganic anions.
