What PURE Bioscience does
PURE Bioscience, Inc. (OTCQB: PURE) is a small publicly traded bioscience company headquartered in El Cajon, California that develops and commercializes antimicrobial products built on its patented Silver Dihydrogen Citrate (SDC) molecule — an electrolytically generated, stabilized ionic silver complexed with citric acid. SDC's dual-mode mechanism (silver ion disruption of membrane proteins combined with a Trojan horse entry via citric acid recognition that denatures microbial DNA) enables broad-spectrum kill in 30-120 seconds against bacteria, fungi, and viruses including SARS-CoV-2, Norovirus, MRSA, VRE, CRE, Listeria, Salmonella, and E. coli, while remaining EPA Category IV (lowest toxicity), non-corrosive, odorless, and multi-year shelf stable. The product portfolio spans PURE Hard Surface (EPA-registered disinfectant and food-contact surface sanitizer), PURE Control (FDA-approved food processing aid under FCN 1768 for poultry and FCN 1600 for produce), PURE Multi-Purpose Cleaner, PURE Multi-Purpose Hi-Foam Cleaner, and PURE Clean, plus the SILVÉRION 2400 sub-brand for personal care preservation.
The company operates a distributor-led go-to-market, selling through more than a dozen U.S. regional chemical and sanitation distributors (AFCO/ZEP, ChemStation, Hydrite, Madison Chemical, ZEE Company, Quip Labs, Bonsai, SaniMarc, Unisan, Wesmar, Agrovet, Guard Products, Marathon Group) across food processing, food service, healthcare, transportation, facility care, and membrane treatment verticals, with named enterprise adopters including Chipotle Mexican Grill (2,100+ locations since 2016) and Taylor Farms. For the personal care and preservative market, PURE supplies SDC Bulk Concentrate (2400 ppm) exclusively through Brenntag Specialties under a licensing model in which customers purchase the raw material and IP rights for defined fields on a worldwide basis. Revenue is generated from product sales and concentrate/licensing, with quarterly net product sales of $707K (Q1 FY2026) and $506K (Q3 FY2026), against persistent operating losses and a stockholders' deficiency of $5.546M with cash of $434K as of October 31, 2025. The company employs 11-50 people and is undergoing a planned CEO transition from Robert Bartlett to President Jeff Kitchell effective July 31, 2026.

PURE Bioscience competitors and assessment
Company assessmentBroad incumbents
- Zep Inc. Zep manufactures and distributes cleaning and sanitation chemicals across industrial, food service, and facility care markets. AFCO/ZEP is already a PURE distributor, making Zep both a peer (competing product lines) and an adjacent channel participant.
- Ecolab: Global leader in water, hygiene, and infection-prevention solutions serving food processing, food service, and healthcare — overlapping with PURE's core verticals. Ecolab's broad sanitizer and disinfectant portfolio competes directly with PURE Hard Surface and PURE Control at large enterprise accounts.
- Halma plc: Halma is a diversified group of safety and environmental health companies, including infection-prevention businesses serving healthcare and life sciences. Through subsidiaries such as Bio-Tek and Andalay, Halma participates in the same low-toxicity disinfection category PURE targets.
- Clorox Company: Clorox operates flagship disinfectant brands (Clorox, Pine-Sol) and a professional products division serving food service, healthcare, and facility care. Clorox Professional competes directly with PURE Hard Surface in commercial surface disinfection.
- Diversey: Diversey (a Solenis company) provides cleaning, sanitizing, and hygiene products across food & beverage, hospitality, and healthcare. Its perimeter and food-contact sanitizer lines are direct competitive alternatives to PURE's SDC-based disinfectants.
Direct peers
- Birko Corporation: Birko is a specialty chemical company focused on food safety sanitation, antimicrobial interventions, and processing aids for meat, poultry, and produce processors. Birko competes head-to-head with PURE Control in the protein and produce processing aid market.
- Decon Labs: Decon Labs manufactures CiDecon and other disinfectant, sanitizer, and cleaning products for pharmaceutical, healthcare, and laboratory markets. Its products overlap with PURE Hard Surface in healthcare and cleanroom disinfection.
- Sterilex: Sterilex makes biofilm-removal and antimicrobial products for food and beverage processing, including PerQuat and Ultra Disinfectant lines. Sterilex is a direct competitor in the no-rinse, food-contact sanitizer and processing aid segments where PURE Hard Surface and PURE Control compete.
Emerging players
- Byotrol: Byotrol develops proprietary multi-active antimicrobial technologies targeting consumer, institutional, and industrial disinfection markets. Like PURE, Byotrol differentiates on novel chemistry and efficacy profile rather than commodity chemistries.
- Virox Technologies: Virox commercializes Accelerated Hydrogen Peroxide (AHP) disinfectant technology — a patented, low-toxicity, broad-spectrum chemistry analogous in positioning to SDC. Virox competes for the same clean-label, food-safe disinfectant positioning in healthcare, food processing, and animal health.
