Purogene® - Chlorine Dioxide Solution

For Airline Potable Water Tank Sanitation

Purogene® is a stabilized chlorine dioxide solution developed by Kemin Bio Solutions to deliver effective, broad-spectrum microbial control in airline potable water storage tanks and distribution systems. When activated with a food-grade GRAS acid, Purogene generates free chlorine dioxide, a selective oxidizer that eliminates bacteria, viruses, fungi, and slime that threaten onboard water safety.

Purogene Logo

Used by leading commercial airlines, Purogene supports routine tank disinfection and ongoing maintenance. Its effective, low-odor formulation makes it ideal for aircraft water systems—helping improve water quality and ensure compliance with aviation sanitation protocols.

Mode of Action 

Upon activation, Purogene produces chlorous acid and free chlorine dioxide. Chlorous acid initiates microbial oxidation, while chlorine dioxide penetrates cell walls and oxidizes intracellular components like proteins, enzymes, and nucleic acids. This two-tier oxidative mechanism rapidly kills microbes and breaks down slime.1,2

Unlike many traditional biocides, chlorine dioxide has a neutral charge and small molecular size, allowing it to effectively penetrate and degrade slime.3 It also leaves behind a residual oxychloro presence, helping maintain bacteriostatic conditions and reducing the likelihood of microbial rebound.4
