Guest guest Posted October 3, 2003 Report Share Posted October 3, 2003 Okay, here is some info on Hydrogen peroxide and no, Carbamide peroxide is NOT a precursor for hydrogen peroxide. Carbamide peroxide is made by compounding urea with hydrogen peroxide. Hydrogen peroxide is produced by the action of sunlight on water. Raggedy Man Food grade and Technical grade hydrogen peroxide are essentially the same. However, the FDA regulates among other things the processing of Food grade hydrogen peroxide. For Example:The manufacturer produces 10 drums of technical grade H2O2. He would test the first and the last drum for quality and purity. The FDA inspects or test all 10 drums. All 10 drums are now considered to be food grade H2O2 after the additives added by the manufacturer for compliance. If the packager pours food grade H2O2 out of one of those drums into a smaller container, it is no longer a "food grade" unless that smaller container is also tested for the FDA compliance. Hydrogen Peroxide Grades 3% Hydrogen Peroxide (Drug/Grocery Store Variety) Used as antimicrobial agent for treating wounds and sanitizing agent[Made from 50% Super D Peroxide, Diluted. Contains stabilizers - phenol, acetanilide, sodium stanate, tetrasodium phosphate among them.] [This peroxide contains known chemicals do not ingest!]6% Hydrogen PeroxideUsed by Beauticians for Coloring Hair. Used as sanitizing agent.Comes in strengths labeled 10,20,40 volume. Must have activator added to be used as a bleach. [Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. Do not ingest.]30% Re-Agent Hydrogen Peroxide Used in medical research.[Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. Do not ingest.]30-32% Electronic Grade Hydrogen Peroxide Used for washing transistors and integrated chip parts before assembly. [Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. Do not ingest.]35% Food Grade Hydrogen Peroxide (Also 50% Food Grade H2O2) Used in food products like cheese, eggs, whey products. Also used to spray inside of foil lined containers for food storage - known as the aseptic packaging system. Used for the disinfection of potable water. Also used (diluted) to disinfect, kill bacteria, sanitize wounds and introduce oxygen into the body. Eg. bathing, gargle, toothpaste, treat drinking water, etc.[Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. --e.g. This Food Grade Hyrogen Peroxide is Stabilized using tin based formulations ] 35% Technical Grade Hydrogen Peroxide (Click to Order Now)Used for waste water treatment and the disinfection of potable water, cosmetics, and laundry applications. Also used (diluted) to disinfect, kill bacteria, sanitize wounds and introduce oxygen into the body. Eg. bathing, gargle, toothpaste, treat drinking water, etc.[May contain a small amount of phosphorus to neutralize any chlorine in the water it is combined with.]MATERIAL SAFETY DATA SHEET & Technical Details: Hydrogen Peroxide (20 to 40%) 35% Standard Grade Hydrogen Peroxide (Also 50%, 60%, 70% Standard Grades)Used mainly for bleaching in the pulp and paper industry and in the textile industry; oxidation reactions in the chemical industry; environmental processes (detoxification and deodorization). Used for Waste water treatment.[Contains stabilizers, additives, and impurities Do not ingest.]90% Hydrogen Peroxide Used by the military as a source of Oxygen at Cape Canaveral. Used as a propulsion source in rocket fuel. 99.6% Hydrogen Peroxide This was first made in 1954 as an experiment to see how pure a hydrogen peroxide could be manufactured. H2O2 is produced to very pure quality standards, however, impurities are actually added to the product by the manufacturer during the manufacture of all grades of hydrogen peroxide to inhibit the catalytic decomposition effect of metals and other impurities that may accidentally contaminate the chemical during shipment, storage, and handling. Additives Purpose Tin (Stannate) Stabilizes product against decomposition caused by heavy metals Phosphate Stabilizes product against decomposition caused by chlorine or heavy metals Nitrate Acts as an inhibitor against the corrosion of aluminum Impurities Source Carbon Organic contamination from the "working solution" or anthraquinone Aluminum From contact with metallic process equipment and piping Chloride From plant water supply Sulfate From plant water supply Ammonium From plant water supply or degradation of organic amines Above are compounds purposely added by manufacturers to stabilize hydrogen peroxide. Many compounds are also added in dilution process. This information is for educational purpose only.
