Antimicrobials & Disinfectants

3. Business Model
• Developer and manufacturer of dmClO2 ™ and other dry-
media antimicrobial products
• Position as provider of most cost/effective point-of-use ClO2
• Strong IP protection plus trade secrets
• Management team with significant operational experience
(sales, marketing, production), financial, and advanced
antimicrobial technology
• Build strategic alliances with partners providing channels of
distribution and/or synergies in application technology

4. The Problem & Its Prevention
• Foodborne diseases - cost $37.1 billion in medical costs and
productivity losses (USDA). Industry currently spending $500
million addressing this problem
• Air Quality - U.S. consumers spend $1.7 billion in fresheners
and deodorizers (mostly masking odors).
• Waterborne diseases - are the # 1 cause of infant mortality in
developing countries and disaster areas
• Hospital-acquired infections- rose by 20% from 2000 to 2003
leading to about 10,000 deaths resulting in excess costs of
$8.73 billion.
• Conventional disinfectants - are not 100% effective against a
comprehensive group of pathogens

Step 1: Water diffusion into M2R™ device
through hydrophilic membrane.
Step 2: Chemicals’ dissolution.
Step 3: Dissolved chemicals exchange across
hydrophilic membrane and chemical reaction
takes place:
5 NaClO2
+ 4 H+
→ 4 ClO2
+ 4 Na+
+ NaCl + 2H2
O
Step 4: Chlorine dioxide (ClO2
) diffuses out of
M2R™ device through hydrophobic membrane
and gaps in the bag.

Step 1: Moisture introduced into M2R™ device
through hydrophobic membrane with the
assistance of deliquescent material.
Step 2: Acid powder becomes hydrated upon
exposure to moisture.
Step 3: Partially dissolved acid (H+
) absorbed
into the inner membrane.
Step 4: H+
acidify the chamber containing sodium
chlorite, and chemical reaction takes place.
Step 5: Generated Chlorine dioxide diffuses out of
M2R™ device through hydrophobic membrane .
