Benzalkonium Chloride 50% (BKC) is a premium quaternary ammonium cationic surfactant and broad-spectrum biocide. It is highly effective at low concentrations against Gram-positive/negative bacteria, algae, and enveloped viruses. BKC is an essential active ingredient in hospital-grade disinfectants, sanitizers, wood preservatives, water treatment systems, and is the primary antimicrobial preservative in ophthalmic, nasal, and otic pharmaceutical formulations.

Benzalkonium Chloride 50% (BKC) is a premier cationic surfactant. In the pharmaceutical and personal care sectors, it acts as an active antimicrobial agent in sanitizers, antiseptic wipes, and surgical disinfectants. It is also the most common preservative used in ophthalmic (eye drop) formulations. Industrially, it is used for algae control in cooling water systems.
Our Benzalkonium Chloride is supplied as a clear, highly stable 50% aqueous solution. We utilize advanced manufacturing techniques to strictly limit the presence of unreacted free amines to less than 1.0%. Every batch undergoes rigorous quality control for exact assay, pH balance, and color clarity to ensure it meets pharmaceutical preservative standards.
While highly effective at low concentrations, bulk BKC 50% is a concentrated surfactant that requires proper protective equipment during handling to avoid skin and eye irritation. It should be stored in tightly sealed HDPE drums in a well-ventilated, ambient environment away from strong oxidizing agents. We provide full MSDS documentation with every shipment.
Comprehensive chemical specs, catalytic pathways, and quality compliance guidelines for raw materials sourcing.
Benzalkonium Chloride (ADBAC) is synthesized by the reaction of alkyldimethylamine (with alkyl groups ranging from C8 to C18, predominantly C12 and C14) with benzyl chloride under controlled temperature and pressure. The reaction yields a quaternary ammonium salt, which is then dissolved in high-purity water to obtain a stable 50% aqueous solution. The cationic nature of the nitrogen head group gives the compound its active surfactant and cell membrane disrupting capabilities.
In pharmaceutical formulations, BKC 50% is primarily used as an antimicrobial preservative in ophthalmic drops, nasal sprays, and topical creams to prevent microbial growth. In industrial water treatment, it is applied as a highly effective algaecide and biocide in cooling towers, heat exchangers, and swimming pools. It is also an essential disinfectant active ingredient in sanitation products, agricultural disinfection, and food processing hygiene.
Manufactured in our GMP-compliant facility, our BKC 50% aqueous solution is strictly tested for free amines (less than 1%) to prevent skin irritation.
It is stored in robust 50 kg or 200 kg HDPE drums in a well-ventilated, cool environment away from strong oxidizing agents.
Personal protective equipment (PPE) including chemical-resistant gloves and goggles is mandatory during bulk handling due to its concentrated surfactant nature.
