Benzalkonium Chloride is a clear, colorless to pale yellow viscous liquid with cationic nature. It is a preservative and disinfecting agent for medical, veterinary, cosmetic, and household products. It is also used for water treatment (algae prevention in cooling water and swimming pools) and for the elimination of fungi, algae, and lichens (substrate pre-treatment agent); for the fungicidal treatment of insulating material based on recycled textiles.

Benzalkonium chloride has a broad spectrum of activity covering mold fungi, algae, and lichens along with slime-forming organisms, bacteria, and yeasts. It is an ideal active ingredient for disinfectants for use in households, sanitizers, and the food processing industry.

Benzalkonium chloride is odorless and is miscible in any ratio with water and lower alcohols. It is approved as a preservative for cosmetics and personal care applications (EC Directive 76/768/EEC and adaptations).
