What is Benzalkonium Chloride？
Benzalkonium Chloride is a type of quaternary ammonium compound that functions as a cationic surfactant, disinfectant, and preservative. It is widely used in industrial, healthcare, pharmaceutical, and cosmetic applications due to its strong antimicrobial properties. As a broad-spectrum biocide, it is effective against bacteria, fungi, and viruses. Benzalkonium Chloride is commonly used in hand sanitizers, surface disinfectants, antiseptic solutions, and ophthalmic products. It appears as a colorless to pale yellow liquid with a characteristic odor. It is miscible with water and soluble in ethanol.

How it works
BKC's effectiveness is due to its ability to interact with microbial membranes, causing them to disrupt and leading to cell death.
It has a fast, long-lasting, broad-spectrum effect against many types of bacteria, fungi, and viruses.
Its efficacy is increased at a high pH level.
Safety profile:
Benzalkonium Chloride is considered safe when used as directed in low concentrations. However, it can be irritating to the skin, eyes, and mucous membranes at higher concentrations. Prolonged or repeated exposure may lead to sensitization. Personal protective equipment is recommended during handling. It is toxic to aquatic life and should be used responsibly to avoid environmental contamination.
Storage requirements:
Store in a cool, dry, and well-ventilated place
Keep container tightly closed
Protect from direct sunlight, heat, and moisture
Avoid contamination with incompatible materials (such as anionic surfactants)
Transport & Packaging:
Benzalkonium Chloride for industrial and technical applications is supplied in various packaging sizes including 25 kg drums 200kg/drum and 1000 kg IBC containers. It should be transported according to regulations for non-hazardous liquid chemicals.
