PURE Bioscience Begins Filling Axen30 Orders for the Home Depot Supply; Axen30 Disinfectant Branded as Germ Control24 for National Distribution

PURE's silver dihydrogen citrate based Axen30 hard surface disinfectant is packaged by Clean Control Corporation and distributed to The Home Depot Supply under the private label Germ Control24(TM). Germ Control24 will be marketed by The Home Depot Supply to its more than half a million customers through monthly direct mail advertising, trade shows, field representatives, The Home Depot Supply website and the January 2005 product catalogue.

The Home Depot Supply, formerly Maintenance Warehouse, is a leading supplier of maintenance, repair and operations (MRO) products to owners and managers of multifamily, hospitality, educational and commercial properties; healthcare providers; and government installations. The Home Depot Supply operates a network of more than 20 warehouse locations across the United States and Canada and employs more than 200 field account managers.

Michael L. Krall, president and CEO of PURE Bioscience stated, "Distribution into The Home Depot Supply is an example of immediate revenue opportunity for our silver dihydrogen citrate based Axen30 now that we have obtained California regulatory approval. We continue our work to establish Axen30 as a leading disinfectant."

Germ Control24(TM): Powerful Disinfectant Spray

Axen30, marketed as Germ Control24 through The Home Depot Supply, is derived from PURE Bioscience's flagship technology: a patented, aqueous antimicrobial called silver dihydrogen citrate (SDC). SDC is an electrolytically generated source of stabilized ionic silver that can serve as the basis for a broad range of products in diverse markets. Colorless, odorless, tasteless and non-caustic, SDC formulates well with other compounds. PURE produces and markets pre-formulated, ready-to-use product, as well as varying strengths of SDC concentrate as an additive or raw material for inclusion in other companies' products.

Axen30, PURE's first commercialized SDC product, is a powerful hard surface disinfectant. The efficacy of Axen30 exceeds that of most leading commercial and consumer products while maintaining a lower toxicity rating. EPA registered claims for Axen30 include a 30 second kill time and a 24 hour residual kill on standard indicator bacteria, a 2 minute kill time on some resistant strains of bacteria including MRSA and VRE, 10 minute kill time on fungi, 30 second kill time on HIV Type I, and 10 minute kill time on other viruses. Recently, PURE received EPA registration of expanded claims for its Axen30 hard surface disinfectant to include use on hard surfaces in childcare facilities. The EPA previously registered Axen30 for disinfection of hard surfaces including those in restaurants, homes and medical facilities. The EPA's registration of Axen30 for use on sensitive children's use sites emphasizes the "least-toxic" characteristics of Axen30 while expanding its versatility in the professional and consumer disinfection markets.
