بنزوالکونیوم کلرید 50%

Benzalkonium Chloride 50% is a cationic surfactant and antiseptic appearing as a clear to slightly yellow viscous liquid. It is widely used in pharmaceutical and laboratory formulations for its antimicrobial, preservative, and stabilizing properties.

🏭⚗️ Production
Benzalkonium chloride is produced by the alkylation of tertiary amines with long-chain alkyl bromides or chlorides under controlled conditions. The 50% aqueous solution is prepared by diluting the concentrated compound, resulting in a stable, highly effective antiseptic solution suitable for pharmaceutical and laboratory applications.

🔬 Properties
Benzalkonium Chloride 50% is soluble in water and alcohol, chemically stable, and exhibits strong cationic surfactant activity. It functions as an effective antimicrobial agent against bacteria, fungi, and some viruses. Its cationic nature allows it to bind to negatively charged surfaces, providing preservative and disinfectant effects without causing significant irritation at recommended concentrations.

🧪 Applications
In pharmaceutical formulations, Benzalkonium Chloride 50% is used in topical antiseptic solutions, eye drops, nasal sprays, and disinfectants to prevent microbial contamination and enhance product stability. It also acts as a preservative in multi-dose formulations to extend shelf-life.
In laboratory settings, it is utilized as a disinfectant, preservative, and antimicrobial agent in experimental formulations, surface sterilization, and microbiological studies.

⚠️ Safety
Benzalkonium Chloride 50% is generally safe when diluted to recommended concentrations for topical and ophthalmic use. It is non-toxic and non-irritating at appropriate dilutions, but concentrated solutions can be corrosive and should be handled with care. Standard handling procedures, including use of protective equipment, proper storage, and hygiene, should be followed to ensure safety during pharmaceutical or laboratory use.
