Hydrogen peroxide is produced by our own immune system's white blood cells to eliminate invading micro-organisms. Excess peroxide is neutralized by enzymes such as catalase or super oxide dismutase (SOD) our own natural internal antioxidizers. It is used as a chemical disinfectant for its microbiocidal activity against bacteria, yeasts, fungi, viruses, and spores. Of the commonly used disinfectants, hydrogen peroxide may be more effective against Staphyloccocus aureus and Pseudomonas aeruginosa biofilms than quat chemical disinfectants.
H2O2 has a major advantage over chlorine in the treatment of water in that it does not produce THM (trihalomethane) disinfection byproducts like trichloromethane (chloroform) & bromodichloromethane. Hydrogen peroxide has a low freezing point and is highly water soluble. Oxygen is released by dissociation and helps prevent future production of sulfides by anaerobic bacteria as in the reaction: SO3 + H2O2 = SO4 + H2O.
Further, it is tasteless & odorless and quickly decomposes into just water & oxygen. This environmental friendliness makes it popular for use in industries as diverse as water treatment, mushroom growing, organic farming, float tanks & cooling towers. It is ideal for eliminating odors caused by naturally occurring bacteria and contaminants.
Hydrogen peroxide is an effective dechlorinating agent and removes dissolved chlorine in concentrations from parts per billion to 1% (10,000 ppm) and more. The dissolved chlorine hydrolyzes to hypochlorous acid (HOCl) which in turn ionizes to hypochlorite (OCl).
Note (1): All test strips Made in the USA & are Q/A'd against NIST standards.
Note (2): Hydrogen peroxide decomposes especially when exposed to sunlight. Frequent testing ensures recommended concentrations are in effect.
Hydrogen peroxide is useful for isolator sterilization in hospital pharmacies and parenteral nutrition preparation units. When hydrogen peroxide dissociates, it produces hydroxyl free radicals that attack essential cell components such as bacterial membranes as well as damaging DNA. In high enough concentration, it overwhelms the catalases that aerobic & facultative anaerobes produce to protect them from oxidative damage.
Warning: Failure to properly remove/rinse 3-6% hydrogen peroxide disinfectant from contact lenses & tonometers (optometric devices that measure intraocular pressure) can cause corneal damage.
Use our hydrogen peroxide dilution calculator to take the guesswork out of diluting pharmaceutical or food grade hydrogen peroxide for use in sprays, spas, pools or hot tubs.
It will tell you how much undiluted peroxide to mix with water.
