Reactivity
Product exhibits antimicrobial activity against bacteria, viruses, mold, mildew, spores, allergens, and microorganisms. This is the product's intended function and does not represent a safety hazard. No other reactivity concerns.

Chemical stability
Stable under normal storage conditions. Product maintains efficacy for 12 months once activated when stored under recommended conditions (sealed containers, away from direct sunlight, at temperatures between 45°F and 100°F). Hypochlorous acid naturally degrades to harmless salt water with prolonged exposure to sunlight or air, which is environmentally beneficial. Product can be reactivated using appropriate electrolysis equipment after the 12-month period.

Possibility of Hazardous Reactions
None under normal storage and usage conditions.

Conditions to avoid
Prolonged exposure to direct sunlight (reduces product efficacy), prolonged exposure of unsealed containers to atmosphere (reduces product efficacy), freezing temperatures, or temperatures above 100°F (38°C).
