Benzalkonium Chloride
Kopalkonium
Benzalkonium chloride (BAC) is a versatile quaternary ammonium compound used for its
antiseptic and disinfectant properties. It is widely employed in various products across
industries such as pharmaceuticals, personal care, and household cleaning. Due to its
ability to inhibit the growth of bacteria and fungi, benzalkonium chloride is also utilized as
a preservative in various pharmaceutical formulations, eye drops, nasal sprays, and
cosmetic products and Biocides

Application & Dosage
The application and dosage of benzalkonium chloride (BAC) depend on its intended use,
whether as an antiseptic, disinfectant, preservative, or biocide
Antiseptic Use of solutions for skin application typically benzalkonium chloride
concentration ranges from 0.1% to 0.2%. The concentration of used as a preservative in
these products is typically lower, often ranging from 0.01% to 0.02%
Stability & Storage Store benzalkonium chloride in a cool, dry place away from direct sunlight and heat sources. Stability can be influenced by factors such as concentration, pH, temperature, and exposure to light. Benzalkonium chloride is stable over a wide range of pH levels, typically between pH 2 and pH 9. It may degrade upon exposure to sunlight or ultraviolet (UV) radiation.
