Povidone iodine solution for livestock and preparation method of povidone iodine solution

Abstract

The invention discloses a povidone iodine solution for livestock and a preparation method of the povidone iodine solution, and belongs to the technical field of disinfectants. The povidone iodine solution for livestock is prepared from the following components in percentage by mass: 8%-12% of povidone iodine, 0.8%-1.2% of povidone, 1.5%-4% of cationic polymerized polypeptide, 0.1%-0.15% of malic acid, 0.03%-0.08% of disodium hydrogen phosphate, 0.16%-0.22% of sodium dihydrogen phosphate, 0.2%-0.3% of potassium iodate, 0.3%-0.5% of potassium iodide and the balance of water. The preparation method comprises the following steps: adding povidone iodine, povidone, cationic polymerized polypeptide and malic acid into water to be dissolved, and obtaining a mixture 1; adding disodium hydrogen phosphate, sodium dihydrogen phosphate, potassium iodate and potassium iodide into water to be dissolved, and obtaining a mixture 2; and mixing the mixture 1 and the mixture 2, and adding water for quantification. The product is good in sterilization effect, stability is obviously improved, effective iodine content is increased, drug resistance is not easily generated, and safety is high.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, and in particular relates to a veterinary povidone-iodine solution and a preparation method thereof. Background technique [0002] Povidone iodine (PVP-I), also known as polyvinylpyrrolidone iodine, is a complex of iodine element and 1-vinyl-2-pyrrolidone (PVP) homopolymer. The molecular structure of povidone-iodine is a relatively unique and stable structure, which is mainly a stable complex formed by polyvinylpyrrolidone and iodine with the help of hydrogen bonds and other attractive forces. Polyvinylpyrrolidone (PV P) is a nonionic surfactant, easily soluble in water, and iodine element is complexed with it, which improves the solubility of iodine element. In addition, the iodine element is combined on the inner side of the polyvinylpyrrolidone helical structure, which greatly enhances the stability of the iodine element. At the same time, this coating structure enables povidone-iodine...

Problems solved by technology

[0006] At present, the povidone iodine solution still has the problem of rapid decomposition under low concentration and the stability needs to be improved. At the same time, it is easy to make the bacterial flora develop drug resistance when used in the breeding field. Therefore, it is necessary to further improve the safety and reduce the bacterial flora. Antimicrobial resistance, further improving the disinfection and sterilization effect
