Abstract

The invention relates to a compound polyninylpyrrolidone sterilizing agent and a preparation method thereof. The sterilizing agent comprises the following components (by wt%): 2.0-10.0% of povidone-iodine PVP-I, 0.05-0.5% of vitamin A, 0.5-1.0% of potassium iodate KIO3, 0.5-1.0% of potassium iodide KI, 0.2-2.0% of chelating agent, 1.0-10.0% of organic solvent, a proper amount of pH modifier, and the balance of water. The preparation method comprises the steps of a. dissolving the povidone-iodine PVP-I and potassium iodate KIO3 into a proper amount of purified water; b. adding the chelating agent and mixing uniformly; c. adding the potassium iodide KI and mixing uniformly; d. adding the vitamin A into the organic solvent and dissolving; e. adding a vitamin A solution d into a povidone-iodine solution c, and mixing uniformly; and f. adjusting the pH to be 7.0-8.0 with the pH modifier, so as to obtain the compound polyninylpyrrolidone sterilizing agent. The compound polyninylpyrrolidone sterilizing agent has stable property and strong sterilizing effect, and can promote wound healing.

Description

technical field [0001] The invention relates to a compound active iodine disinfectant. Background technique [0002] Povidone-iodine (Polyvinyl pyrrolidone-Iodine, PVP-I) is a new type of iodine-containing sterilizing preparation. PVP-I is a complex formed by polyvinylpyrrolidone (PVP) and iodine, containing 9~12% of available iodine. PVP is stable in nature and generally does not cause incompatibility with other drugs. After forming a complex with iodine, the iodine element is combined with the inner side of the PVP helical structure, which greatly improves the solubility of iodine. for continuous disinfection. Povidone-iodine is in a complex state under stable conditions, which overcomes the shortcomings of iodine in iodine tincture, such as easy sublimation, irritation, and yellow dye that needs to be deiodized with ethanol. Povidone-iodine, although effective in inhibiting bacteria on undamaged skin surfaces, did not promote wound healing. There is evidence that iodi...
