Problems solved by technology

[0002] Iodine is the most commonly used skin disinfectant. It has excellent bactericidal effect due to strong penetration and other reasons, but it cannot be widely used because of its high irritation.
Polyvinylpyrrolidone-iodine aqueous solution is a new type of iodine disinfectant, referred to as PVPI solution, and its trade name is povidone-iodine solution. In addition to having the same effect as iodine, it has expanded uses because of its milder performance, but it is the same as iodine , still exist on the surface of the skin for not long enough, easy to be rubbed off
Disadvantages of not being able to use on bleeding wounds etc.

Abstract

The invention discloses a long-acting disinfection paste, which belongs to the field of skin and vaginal disinfectors, and is characterized by being formed by mixing polyvivyl pyrrolidone iodine, water soluble high polymers without side effects, an auxiliary agent and water in a certain ratio. In the product, the content of effective iodine is one time higher than that required by relative national standards, so that the disinfecting and sterilizing capability of the product is greatly improved, and the adverse reactions are avoided. The product can form a film on the skin surface to be adhered to the skin to avoid being rubbed out, thereby prolonging the disinfecting and sterilizing time by several times and offering a long-acting effect. The product can be used for treating small bleeding wounds without causing adverse reactions. The product has certain effects of treating skin abscesses, sores and furuncles and preventing the transmission of venereal diseases and AIDS. The product has the advantages of simple production equipment and process and high production efficiency. The result of many years of actual use shows that the product has a remarkable effect and is expected to replace various iodine disinfectors sold in the market presently.
