Bleaching About 60% of the world's production of<unk>  is used for pulp- and paper-bleaching. The second major industrial application is the manufacture of sodium percarbonate and sodium perborate, which are used as mild bleaches in laundry detergents. Sodium percarbonate, which is an adduct of sodium carbonate and<unk> , is the active ingredient in such laundry products as OxiClean and Tide laundry detergent. When dissolved in water, it releases<unk>  and sodium carbonate, By themselves these bleaching agents are only effective at wash temperatures of or above and so, often are used in conjunction with bleach activators, which facilitate cleaning at lower temperatures. It has also been used as a flour bleaching agent and a tooth whitening agent. Production of organic compounds It is used in the production of various organic<unk> s with dibenzoyl<unk>  being a high volume example. Peroxy acids, such as peracetic acid and meta-chloroperoxybenzoic acid also are produced using<unk> .<unk>  has been used for creating organic<unk> -based explosives, such as acetone<unk> . It is used as an initiator in polymerizations. Sewage treatment<unk>  is used in certain waste-water treatment processes to remove organic impurities. In advanced oxidation processing, the Fenton reaction gives the highly reactive hydroxyl radical (·OH). This degrades organic compounds, including those that are ordinarily robust, such as aromatic or halogenated compounds. It can also oxidize sulfur-based compounds present in the waste; which is beneficial as it generally reduces their odour. Disinfectant<unk>  may be used for the sterilization of various surfaces, including surgical tools, and may be deployed as a vapour <unk>  for room sterilization.<unk>  demonstrates broad-spectrum efficacy against viruses, bacteria, yeasts, and bacterial spores. In general, greater activity is seen against Gram-positive than Gram-negative bacteria; however, the presence of catalase or other<unk> ses in these organisms may increase tolerance in the presence of lower concentrations. Lower levels of concentration (3%) will work against most spores; higher concentrations (7 to 30%) and longer contact times will improve sporicidal activity.<unk>  is seen as an environmentally safe alternative to chlorine-based bleaches, as it degrades to form oxygen and water and it is generally recognized as safe as an antimicrobial agent by the U.S. Food and Drug Administration (FDA). Propellant Rocket-belt<unk>  propulsion system used in a jet pack High-concentration is referred to as "high-test<unk> " (HTP). It can be used either as a monopropellant (not mixed with fuel) or as the oxidizer component of a bipropellant rocket. Use as a monopropellant takes advantage of the decomposition of 70–98% concentration<unk>  into steam and oxygen. The propellant is pumped into a reaction chamber, where a catalyst, usually a silver or platinum screen, triggers decomposition, producing steam at over , which is expelled through a nozzle, generating thrust. monopropellant produces a maximal specific impulse (Isp) of 161 s (1.6 kN·s/kg).<unk>  was the first major monopropellant adopted for use in rocket applications. Hydrazine eventually replaced<unk>  monopropellant thruster applications primarily because of a 25% increase in the vacuum specific impulse. Hydrazine (toxic) and<unk>  (less-toxic ACGIH TLV 0.01 and 1 ppm respectively) are the only two monopropellants (other than cold gases) to have been widely adopted and utilized for propulsion and power applications. The Bell Rocket Belt, reaction control systems for X-1, X-15, Centaur, Mercury, Little Joe, as well as the turbo-pump gas generators for X-1, X-15, Jupiter, Redstone and Viking used<unk>  as a monopropellant. As a bipropellant, is decomposed to burn a fuel as an oxidizer. Specific impulses as high as 350 s (3.5 kN·s/kg) can be achieved, depending on the fuel.<unk>  used as an oxidizer gives a somewhat lower Isp than liquid oxygen, but is dense, storable, non-cryogenic and can be more easily used to drive gas turbines to give high pressures using an efficient closed cycle. It may also be used for regenerative cooling of rocket engines.<unk>  was used very successfully as an oxidizer in World War II German rocket motors (e.g. T-Stoff, containing oxyquinoline stabilizer, for both the Walter HWK 109-500 Starthilfe RATO externally podded monopropellant booster system, and for the Walter HWK 109-509 rocket motor series used for the Me 163B), most often used with C-Stoff in a self-igniting hypergolic combination, and for the low-cost British Black Knight and Black Arrow launchers. Presently, HTP is used on ILR-33 AMBER and Nucleus suborbital rockets. In the 1940s and 1950s, the Hellmuth Walter KG–conceived turbine used<unk>  for use in submarines while submerged; it was found to be too noisy and require too much maintenance compared to diesel-electric power systems. Some torpedoes used<unk>  as oxidizer or propellant. Operator error in the use of<unk>  torpedoes was named as possible causes for the sinking of HMS Sidon and the Russian submarine Kursk. SAAB Underwater Systems is manufacturing the Torpedo 2000. This torpedo, used by the Swedish Navy, is powered by a piston engine propelled by HTP as an oxidizer and kerosene as a fuel in a bipropellant system. Household use Contact lenses soaking in a 3%<unk> -based solution. The case includes a catalytic disc which neutralises the<unk>  over time.<unk>  has various domestic uses, primarily as a cleaning and disinfecting agent. ;Hair bleaching Diluted (between 1.9% and 12%) mixed with aqueous ammonia has been used to bleach human hair. The chemical's bleaching property lends its name to the phrase<unk>  blonde".<unk>  is also used for tooth whitening. It may be found in most whitening toothpastes.<unk>  has shown positive results involving teeth lightness and chroma shade parameters. It works by oxidizing colored pigments onto the enamel where the shade of the tooth may become lighter.<unk>  may be mixed with baking soda and salt to make a homemade toothpaste. ;Removal of blood stains<unk>  reacts with blood as a bleaching agent, and so if a blood stain is fresh, or not too old, liberal application of<unk> , if necessary in more than single application, will bleach the stain fully out. After about two minutes of the application, the blood should be firmly blotted out. ;Acne treatment<unk>  may be used to treat acne, although benzoyl<unk>  is a more common treatment. Niche uses Chemiluminescence of cyalume, as found in a glow stick ;Glow sticks<unk>  reacts with certain di-esters, such as phenyl oxalate ester (cyalume), to produce chemiluminescence; this application is most commonly encountered in the form of glow sticks. ;Horticulture Some horticulturalists and users of hydroponics advocate the use of weak<unk>  solution in watering solutions. Its spontaneous decomposition releases oxygen that enhances a plant's root development and helps to treat root rot (cellular root death due to lack of oxygen) and a variety of other pests. For general watering concentrations around 0.1% is in use and this can be increased up to one percent for anti-fungal actions. Tests show that plant foliage can safely tolerate concentrations up to 3%. ;Fishkeeping<unk>  is used in aquaculture for controlling mortality caused by various microbes. In 2019, the U.S. FDA approved it for control of Saprolegniasis in all coldwater finfish and all fingerling and adult coolwater and warmwater finfish, for control of external columnaris disease in warm-water finfish, and for control of Gyrodactylus spp. in freshwater-reared salmonids. Laboratory tests conducted by fish culturists have demonstrated that common household<unk>  may be used safely to provide oxygen for small fish. The<unk>  releases oxygen by decomposition when it is exposed to catalysts such as manganese dioxide.
