Microcyn can produce a bland oxidized chlorine compound which is pH-neutral and stable for storage and this compound can mimic the function of neutrophil granuulocytes in human. Neutrophil granuulocytes are the most abundant type of white blood cell in human and form an essential part of the human immune system. Because it can react with the lipids and proteins in cell membrane, oxidized chlorine compound can lead to the burst and rapid death of the microorganism as the result of its mechanism of fighting against single-cell microorganism mechanism. Meanwhile, Microcyn product can have a good biocompatibility with mammalian cells because these cells have formed a bio-mechanism to tolerate and regulate the active composition in Microcyn during the process of evolution. The pathogenic microorganisms are lack of this capability. Research has demonstrated that Mycrocyn can induce vasodilatation and there is undisputed biocompatibility between fibroblasts and granulation tissue. The headquarters of this company is located in Petaluma, California, USA and the business operates in Europe, Latin America and Japan.  Microcyn Liquid Dressing (Microcyn) is a broad-spectrum bactericide manufactured by U.S. Oculus Innovative Sciences, Inc. The company obtained the 510K clearance from U.S. Food and Drug Administration to market this product. In the same year, it received the medical instrument market permission specified by EU 93/42/EEC Medical Instrument Instruction and is authorized to use “CE” marker. In 2008, it was registered at state Food and Drug Administration and received medical instrument registration certificate: GuoShiYaoJianXie (Jin) 2008 No. 2640099. It is a third-tier medical instrument and is the only broad-spectrum bactericide that can be used over human body surface and lacunar membrane in our country. Microcyn is a super-oxidized solution which is used for debridement, douching, moistening the acute and chronic wounds, ulcer, incision, abrasion and burns. Not only can it kill bacteria, germs, fungi and virus safely and rapidly to control infection, but it can indirectly increase the blood circulation around wound surface and accelerate the wound concrescence. There is no residues in human internal environment and no pollution to living conditions. It is a green, broad-spetrum anti-pathogenic microorganism germicidal solution which can replace antibiotics and there are no residues in human internal environment and no pollution to living conditions. It has destroying effect for antibiotics resistant strains, such as meticillin resistant ataphylococcus aureus(MRSA) and Vancomycin resistant enterococcus faecalis (ARE), specific bacteria, such as tubercle bacillus and aeruginosus bacillus and viruses, such as HIV-I.
