Pure Bioscience

Pure Bioscience, Inc. (NASDAQ: PURE) is an antimicrobial technology company that has developed and commercialized PURE Hard Surface — a proprietary silver dihydrogen citrate (SDC) antimicrobial solution — for use as a disinfectant and sanitizer in food manufacturing, commercial foodservice, healthcare, and other environments requiring effective, safe, and residue-free pathogen control. According to its website at purebio.com, the company's silver-based antimicrobial chemistry provides broad-spectrum kill efficacy against a wide range of bacterial, viral, and fungal pathogens — including MRSA, C. difficile, E. coli, Salmonella, and SARS-CoV-2 — while meeting EPA and FDA regulatory requirements for use in food contact environments where conventional quaternary ammonium and bleach disinfectants may leave unacceptable chemical residues. PURE Hard Surface's safety profile, food-contact approval, and broad-spectrum efficacy distinguish it in the commercial disinfection market.

Pure Bioscience's antimicrobial product platform, described at purebio.com, is based on the company's proprietary SDC technology — a formulation of silver dihydrogen citrate that harnesses silver's well-established antimicrobial properties in a water-soluble, pH-stable, and food-safe chemical form that can be used without protective equipment or special handling precautions that are required for more caustic conventional disinfectants. The company's products are EPA-registered disinfectants meeting the rigorous efficacy testing requirements for pathogen kill claims, and are approved for use on food contact surfaces — a critical differentiation for food manufacturing and foodservice customers whose disinfection needs require products that won't contaminate food products with harmful chemical residues. PURE Hard Surface is used in food processing plants, commercial kitchens, school cafeterias, grocery stores, and other food-handling environments.

Pure Bioscience markets its PURE Hard Surface products directly to food manufacturing, food processing, and foodservice customers and through distributors serving the food safety and institutional cleaning markets. According to purebio.com, the company's commercial strategy focuses on building awareness and adoption among food safety managers, food plant sanitation teams, and commercial kitchen operators who are seeking more effective and food-safe disinfection solutions than conventional quaternary ammonium products — particularly as awareness of foodborne illness risks, regulatory pressure on food safety practices, and post-pandemic heightened hygiene standards have increased demand for demonstrably effective, food-safe antimicrobial solutions. Pure Bioscience's combination of proprietary silver-based antimicrobial technology, EPA-registered disinfectant efficacy, food contact surface approval, food manufacturing market focus, and Nasdaq-listed structure positions it as a specialized antimicrobial technology company serving the food safety and commercial hygiene markets.
