Pharmaceutical Information
Drug Name Benzalkonium
Drug ID BADD_D00234
Description Benzalkonium is a quaternary ammonium compound used as a biocide, a cationic surfactant, and as a phase transfer agent [FDA Label]. Benzalkonium is more commonly contained in consumer products in its salt form, benzalkonium chloride [FDA Label]. This salt is used in a great variety of international pharmaceutical products such as eye, ear, and nasal drops or sprays as an excipient ingredient serving as an antimicrobial preservative [FDA Label]. When used as an ingredient in antiseptic and disinfectant products however, it is an active antimicrobial agent [L1806].
Indications and Usage When used as an active ingredient in products like antibacterial, antiseptic, or disinfectant soaps, topical sanitizers, or cleaning agents, benzalkonium is primarily implemented in its salt form, benzalkonium chloride, where it may often be the only active ingredient present and indicated for the primary purpose of topical washing to decrease bacteria on skin [L1806]. Conversely, when implemented as an excipient ingredient in a variety of multidose aqueous nose, eye, or ear products, benzalkonium chloride is being used as the antimicrobial preservative of choice to facilitate effective bactericidal and fungicidal actions to help minimize the growth of unwanted organisms in the multidose containers [FDA Label].
