Shanghai Qifuqing Material Technology Povidone Iodine PVP-I

It can be used for skin disinfection and instrument disinfection in hospital operations, injections, anti-infection in oral, gynecology, surgery, dermatology, etc., sterilization and disinfection of household utensils and utensils, sterilization and disinfection in food industry, breeding industry, and animal disease prevention and treatment. Povidone-iodine is mainly used as a disinfectant and antiseptic, used for purulent dermatitis, skin fungal infection, small-area mild burns and scalds, and also used for the disinfection of small-area skin and mucous membrane wounds. The mechanism of action is that the product can depolymerize and release the iodine contained in it to play a bactericidal effect after it contacts the wound or affected area. It is characterized by low irritation to tissues and is suitable for skin and mucous membrane infections.

Medical hygiene

• Mechanism of action: PVP is a hydrophilic polymer and has no antibacterial effect. However, due to its affinity for cell membranes, it can directly introduce iodine to the cell surface of bacteria, which is of great significance for improving the antibacterial activity of iodine.

• The target of iodine's attack is the bacterial cytoplasm and cytoplasmic membrane, killing the bacteria immediately within a few seconds.

• When molecules necessary for survival such as mercapto compounds, peptides, proteins, lipids, and cytosine come into contact with PVP-I, they are immediately oxidized or iodinated by iodine, causing them to lose their activity and achieve a longer-term bactericidal effect.

Food hygiene

PVPI's excellent sterilization and disinfection ability and its physiological compatibility show that it has no irritation and allergic reaction to the human body, making it widely used in food, preservation, catering industry disinfection, etc., and in some aspects it shows unique advantage. If the refrigerator is sprayed with 0.1% PVP-I solution once a week, it can ensure that there is no peculiar smell in the refrigerator for a long time.

Aquaculture

The application of PVP-I in the aquaculture industry has only been developed in recent years, and is currently being further expanded. With the further development of the aquaculture industry in my country, PVP-I as a sterilization and disinfectant in the aquaculture industry has broad prospects. PVP-I is a broad-spectrum disinfectant that has varying degrees of killing effect on most bacteria, fungi and viruses. It is used for the prevention and treatment of fish, shellfish, shrimp, and crab diseases; in livestock and poultry The disinfection and disease treatment of breeding also have obvious effects.
