Benzethonium Chloride vs. Benzalkonium Chloride: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 8, 2024
Benzethonium chloride is a synthetic quaternary ammonium salt used as an antimicrobial agent, while benzalkonium chloride is a mixture of alkylbenzyldimethylammonium chlorides with similar uses.
Key Differences
Benzethonium chloride is a synthetic quaternary ammonium compound with a specific chemical structure (C27H42ClNO2). Benzalkonium chloride, on the other hand, is a mixture of alkylbenzyldimethylammonium chlorides, where the alkyl group varies in length (C8-C18).
Both compounds are known for their antimicrobial properties. Benzethonium chloride is effective against a broad range of microorganisms, including bacteria and fungi. Benzalkonium chloride also exhibits broad-spectrum antimicrobial activity and is commonly used as a disinfectant and antiseptic.
Benzethonium chloride is used in personal care products, such as hand sanitizers and antiseptic wipes, and in pharmaceutical products. Benzalkonium chloride is widely used in disinfectants, sanitizers, and in preservatives in ophthalmic and nasal preparations.
Both compounds are generally safe when used as directed, there are concerns about skin irritation and sensitivity, especially with frequent use. Benzalkonium chloride is known to be more irritating to the skin and mucous membranes compared to benzethonium chloride.
The use of benzethonium chloride and benzalkonium chloride in various products is regulated differently in different regions. Both are approved for use in certain concentrations in consumer and medical products, but regulations may vary.
