Functions of Cationic Surfactant - Sterilization

Sterilization

The quaternary ammonium salt bactericide has the property of an ionic compound, which is highly soluble in water and is insoluble in a non-polar solvent, with stable Chemical properties. The mechanism of action of this kind of fungicide is mainly the action of cations through electrostatic force, hydrogen bonding force and hydrophobic interaction between surfactant molecules and protein molecules, adsorbing negatively charged bacteria, causing them to accumulate on the cell wall, causing bacteriolysis and A ventricular resistance effect occurs, causing bacterial growth to be inhibited and die. At the same time, its hydrophobic alkyl group can also interact with the hydrophilic group of bacteria to change the permeability of the membrane, which in turn causes lysis, destroys the cell structure, and causes cell lysis and death. These fungicides are highly effective, low-toxic, non-accumulative, moderately toxic to fish, and are not susceptible to pH changes. They are easy to use and have strong peeling effect on the mucus layer. It has the characteristics of stable chemical properties, good dispersion and corrosion inhibition.

Since the bactericidal action of cationic surfactants was discovered in 1935, 4 to 6 generations of quaternary ammonium bactericides have been developed to date. The first generation is alkyl dimethyl benzyl ammonium chloride, cetyl trimethyl ammonium chloride and the like. The second generation is a derivative of the first generation obtained by subjecting a substitution reaction to a benzene ring or a quaternary nitrogen of a quaternary ammonium salt. The third generation product is dialkyl dimethyl ammonium chloride, such as dikut dimethyl ammonium chloride. The fourth generation is the compound product of the first and third generations. The fifth generation is a double quaternary ammonium salt such as ethylene bis(dodecyldimethylammonium bromide), which is a dimeric or dimeric surfactant.

The quaternary ammonium salt bactericide not only has a bactericidal effect, but also has a strong peeling effect on the slime, which can kill the sulfate reducing bacteria grown under the slime, and has a corrosion inhibition synergistic effect when used together with other agents. Common are 1227 (dodecyldimethylbenzylammonium chloride), 1231 (dodecyltrimethylammonium chloride), neostigmine (dodecyldimethylbenzylammonium bromide), 1427 (tetradecyldimethylbenzylammonium chloride), ethylene bis(dodecyldimethylammonium bromide), ethylene bis(tetradecyldimethylammonium chloride), and so on.
