Povidone iodine is elemental iodine and a polymer carrier bonded with loose composite, povidone acts as a vehicle and a co-solubilization. At room temperature, yellow-brown to red-brown amorphous powder. Slight odor, soluble in water or alcohol, acidic aqueous solution and insoluble in ether, chloroform, acetone, carbon tetrachloride, and ethane.
Povidone-iodine solution without the disadvantages of iodine, light color, readily soluble, small mucous membrane irritation, without deiodination ethanol, non-corrosive, and low toxicity.
A by surfactant and iodine complex and unstable complex, iodine v type of topical disinfectant, room temperature is yellow brown to reddish brown amorphous powder, soluble in water or ethanol, not soluble in ether and chloroform. 1 - vinyl - 2 - arsenic of alkane ketone homopolymer of surfactant and help solution of wetting and penetration of the object, thus strengthening the bactericidal effect of iodine. The combination of 80 ~ 90% iodine can be depolymerized to free iodine, concentration, strong sterilization, tasteless, no stimulation, no sensitization effect, low toxicity.

Usage: Polymers; pharmaceutical intermediates; intermediates; food and feed additives; food bactericides; catalysts and auxiliaries; chemical auxiliaries; pharmaceutical excipients and pharmaceuticals; pharmaceuticals and biochemicals; organic materials; Polymer science; API; fungicide; hydrophobic polymer; synthetic anti-infective drug; disinfectant antiseptic; raw material drug; pharmaceutical raw material; disinfectant; Iodine bactericidal action; raw material; anti-viral anti-infective; veterinary drug raw material; Veterinary drug
Mainly used in hospital operating; injections and other skin disinfection and sterilization equipment, as well as dental, gynecology, surgery, dermatology and other infection prevention; household utensils, appliances and other disinfection; food industry, aquaculture industry for disinfection and animal disease control , iodine is the preferred international and domestic health and epidemic prevention and medical fungicides disinfectants.
Sterilization with iodine as the disinfectant medicament, bacteriostatic agents for eye drops, creams and the like antiseptic, disinfectant can also be made.
Iodine carrier. Tamed iodine "tamed iodine.", This product due to the gradual release of iodine can play antibacterial effect, its mechanism of action is the bacterial protein denaturation, death. Bacteria, fungi, viruses are effective, which is characterized by the organization with little irritation.
External disinfectant: Povidone iodine is an unstable complex formed by complexing surfactant with iodine. It is an external disinfectant for iodophor. It is a yellow-brown to reddish brown amorphous powder at room temperature, and is easily soluble in water or ethanol. Medium, insoluble in ether or chloroform.
The 1-vinyl-2-pyrrolidone homopolymer is a surfactant which helps the solution to wet and penetrate the object, thereby enhancing the bactericidal action of iodine. Among them, 80-90% of the combined iodine can be depolymerized into free iodine, the concentration is large, the bactericidal power is strong, tasteless, non-irritating, non-sensitizing and low in toxicity. It is a broad-spectrum fungicide that kills viruses, bacteria, spores, fungi, and protozoa.
It can kill the propagules of various bacteria (Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) within 1 minute at a concentration of 15 ppm. It takes a long time to kill Mycobacterium tuberculosis, and it takes 1.5 hours to kill the fungus (Bacillus subtilis). It is necessary to kill the black variant spores and the Bacillus cereus spores at a higher concentration and for a longer period of time; the hepatitis B surface antigen (HBsAg) can be destroyed at a concentration of 150 ppm for 10 minutes.
In addition to skin disinfection, this product can also be used for disinfection of metal medical devices and utensils. It is usually red or amber at the concentration used for disinfection. It can be directly used for the skin and meninges of the incision site of surgical patients. It can also be used for external gynecology and urology. When the concentration is lowered to 10 ppm or less, it becomes white or pale yellow, and the bactericidal activity is lost.
Povidone iodine is an iodophor disinfectant, which can directly denature and precipitate proteins in the bacteria, causing the death of pathogenic microorganisms, thereby effectively disinfecting and sterilizing, killing viruses, bacteria, spores, fungi, protozoa, etc., and having low toxicity. The povidone-iodine aqueous solution has strong pharmacological activities against Staphylococcus aureus, Neisseria gonorrhoeae, Pseudomonas aeruginosa, Treponema pallidum, Hepatitis B virus, HIV, Trichomonas vaginalis, and the like.
The povidone-iodine gel is a gynecological external semi-flow colloid made of povidone iodine and a hydrophilic matrix, which is a system for maintaining its sustained release. Due to the continuous release of free iodine, the skin and mucous membranes maintain a certain concentration of iodine, which inhibits bacteria. It is mainly used for gynecological vaginal infection, miscible with vaginal secretions, killing pathogenic microorganisms in secretions, blocking the spread and invasion of sexually transmitted diseases, and treating other bacterial infections of vaginal diseases.
