Hydrogen peroxide 3% Pharm., without sodium benzoate (without preservative E211), 100ml
Manufacturer - Merck, Germany
Used in folk and alternative medicine, in particular according to the method of I. Neumyvakina for the treatment and prevention of various diseases.
Hydrogen peroxide (hydrogen peroxide), H2O2 is the simplest representative of peroxides. Colorless liquid with a metallic taste, miscible in all proportions in water, alcohol and ether. Concentrated aqueous solutions of explosive. Hydrogen peroxide is a good solvent. Water is excreted in the form of an unstable crystalline H2O2∙2H2O.
Biological properties
Hydrogen peroxide refers to reactive forms of oxygen and at an elevated formation in the cell causes oxidative stress. Some enzymes, such as glucoseoxidase form during the redox reaction of hydrogen peroxide, which may play a protective role as bactericidal agent. In mammalian cells, no enzymes that would have restored oxygen to hydrogen peroxide. However, several enzyme systems (xanthine oxidase, NADP•H-oxidase, cyclooxygenase, etc.) produce superoxide, which spontaneously or under the action of superoxide dismutase is converted into hydrogen peroxide.
Application
Due to its strong oxidizing properties, hydrogen peroxide has found wide application in everyday life and in industry where it is used, for example, as bleach in the textile industry and in the manufacture of paper. Used as a rocket fuel, as an oxidizer or as a single component (with decomposition catalyst), including to drive the turbopumps.[6] Used in analytical chemistry, as blowing agents in the production of porous materials, in the manufacture of disinfecting and bleaching agents. In industry hydrogen peroxide also finds application as a catalyst, the hydrogenation agent, as epoxygenase agent in the epoxidation of olefins.
Although dilute solutions of hydrogen peroxide are applied to a small surface wounds, studies have shown that this method, providing antiseptic and cleansing also prolongs the time of healing[7][8]. Having good cleaning properties, hydrogen peroxide't really speeds healing. Sufficiently high concentration, providing an antiseptic effect, can also prolong the healing time because of damage adjacent to the wound cells[9]. Moreover, hydrogen peroxide can hinder healing and promote scarring due to the destruction of the newly-forming skin cells.
However, as a means to clean the deep wounds of the complex profile, purulent streaks, abscesses and other purulent wounds, rehabilitation of which is difficult, hydrogen peroxide remains the preferred drug, as it not only has antiseptic effect, but also creates a large amount of foam in the interaction with the enzyme catalase. This in turn allows you to soften and separate from nekrotizirovannye tissue sections, blood clots, pus, which is easily washed away by the subsequent introduction into the cavity of the wound with antiseptic solution. Without pre-treatment with hydrogen peroxide is an antiseptic solution will not be able to remove these pathological education, which will lead to a significant increase in healing time of the wound and worsen the patient's condition.
Hydrogen peroxide is used to dissolve the plugs in the ear canals. The solution reacts with and dissolves earwax plug.
Hydrogen peroxide is also used for bleaching hair and whitening teeth, but the effect in both cases is based on the oxidation and hence destruction of the tissues. During teeth whitening, however, there is no destruction of tissue. Pigmented dentin proteins begin to unwind to the primary structure (as if the white of an egg boiled became more raw), but the relation is not dissolved, that is, this process is reversible. The enamel itself is transparent, and the whitening effect is achieved due to the difference in light reflection of the dentin.
In food industry, hydrogen peroxide solutions are used for disinfection of technological equipment surfaces that come into direct contact with the product. In addition, enterprises for the production of dairy products and juices, solutions of hydrogen peroxide are used for disinfection of the packaging (technology "Tetra Pak"). For technical purposes, the hydrogen peroxide used in the manufacture of electronic equipment.
In the home is used also for removing stains MnO2 formed by the interaction of potassium permanganate ("manganese") with objects (due to its regenerative properties).
3% solution of hydrogen peroxide is used in the aquarium for reviving asphyxiated fish and for cleaning aquariums and suppression of unwanted flora and fauna in the aquarium.
Since the 90-ies of XX century 3% solution of hydrogen peroxide advanced healer I. P. by Neumyvakin for ingestion as a universal means of curing and healing people. Scientific evidence of the validity and effectiveness of this method has.
The danger of the use
Despite the fact that hydrogen peroxide is non-toxic, its concentrated solutions in contact with the skin, mucous membranes and respiratory tract causes burns. In high concentrations it is not clean enough hydrogen peroxide can be explosive. Dangerous ingestion of concentrated solutions. Causes marked destructive changes similar to the action of alkalis. Lethal dose of a 30% solution of peroxide of hydrogen (perhydrol) — 50-100 ml.
