Benzalkonium chloride, known as (BAC, BKC, BZK), is a cationic surfactant. This compound is used as a disinfectant in hospitals, livestock, and personal hygiene, and also as a mold, antistatic agent, emulsifier, and an additive in weaving and dyeing. BAC is sold with quality assurance in accordance with the analysis provided by Shanghai Chemex group Ltd in China.
Physical and Chemical Properties:
Benzalkonium chloride, depending on its purity, changes color from colorless to yellow, which is less pure. This substance dissolves slowly in water and has good solubility in ethanol and acetone. In saturated solutions, this substance has a bitter taste with an odor similar to almonds; In the table below some of the chemical and physical properties of this product are mentioned:
|Molecular Weight (g/Mol)||variable|
|Appearance||colorless to pale yellow solution|
|odor||faint almond odor|
|Density (g/cm3 at 25 °C)||0.98|
|Solubility in water||very soluble|
|Flash Point (° C)||250|
|Synonyms||N-Alkyl-N-benzyl-N, N-dimethylammonium chloride; Alkyldimethylbenzylammonium chloride; ADBAC; BC50 BC80; Quaternary ammonium compounds; quats|
|Chemical Structure Depiction|
Benzalkonium Chloride Grades:
If we want to categorize Benzalkonium chloride, we see that it has both food grade and industrial grade. Its food-grade must be rinsed from the surface of the devices after consumption. In industrial grade, it also varies according to the type of rinsing application. But based on functionality, it can be used in two degrees:
- Preservative and antimicrobial
Synthesis of Benzalkonium Chloride:
Initially, alkyl dimethyl amide, thiocarbamide, and benzyl chloride are placed in glass reactors in certain proportions and a mechanical stirrer and steam heater are activated. The temperature must be controlled until the reaction takes place, and after the reaction is complete, the solution is cooled until crystals form. The crystallization process is then performed using an organic solvent and finally dried under a vacuum until a constant weight is reached.
Benzalkonium Chloride Uses:
As a cationic surfactant, it dissolves the lipid phase of the drug film and increases its absorption, which makes it a widely used substance. In addition, due to its surfactant properties, this material is also used in the production of detergents and fabric softeners.
Benzalkonium chloride is the mainstay of phase transfer analysis, an important technology in the synthesis of organic compounds, including drugs.
Biologically Activating Agents:
- Personal care products such as hand sanitizers, wipes, shampoos, soaps, deodorants, and cosmetics
- Skin disinfectants and wound cleansing sprays
- Production of therapeutic products used to treat herpes, blisters
- Treatment of burns and wounds
- Disinfectant spray for disinfecting hard surfaces
- Floor and surface cleaners
- To clear algae, moss, and lichens from paths, roof tiles, swimming pools, masonry, etc.
Benzalkonium Chloride Price:
Benzalkonium chloride is a fourth type of ammonium that is mostly used as a disinfectant and antimicrobial. You can contact our experts at Shanghai Chemex for more information on how to place an order and purchase this product.
