Povidone-iodine solution and preparation method thereof

Abstract

The invention relates to a povidone-iodine solution and a preparation method thereof. Each 100g of the povidone-iodine solution is mainly prepared from, by weight, 0.02-0.5g of potassium iodate, 0.1-3.5g of potassium iodide, 0.5-5g of PVP, 1-5g of polyethylene glycol, 2-10g of polyurethane, 0.1-5g of sodium alginate, 0.2-0.5g of organic acid, 0.5-3.5g of surfactant, 1-5g of plasticizer and the balance of water and pH regulator. The povidone-iodine solution is safe, reliable, high in stability and good in film forming effect, a film formed by the solution is not high in toughness and less proneto shedding, efficacy is lasting, antibacterial effect is ensured, a lot of labor and medication cost can be saved, and the solution is suitable for extensive dairy cow farms.

Description

technical field [0001] The invention relates to the technical field of veterinary disinfectants, in particular to a povidone-iodine solution and a preparation method thereof. Background technique [0002] In the dairy farming industry, dairy cow mastitis has always been a problem for dairy farmers, and it is also one of the main causes of economic losses for dairy farmers. Every time before and after milking, the nipples of cows should be disinfected to prevent and control the occurrence of mastitis in cows, especially after dipping plays an important role in preventing mastitis in cows. Most of the dairy cow medicated baths currently available in the market have a high water content, which makes the medicated bath drip after infiltrating the cow's teats, does not adhere to the cow's teats, or is easily rubbed off by the cow's bed, which greatly affects the effect of the post-medication bath and causes waste of medication . [0003] It can be seen from the article "Develop...

AI Technical Summary

Problems solved by technology

Most of the dairy cow medicated baths currently on the market have a high water content, which makes the medicated bath drip after infiltrating the cow’s teats, does not adhere to the cow’s teats, or is easily rubbed off by the cow’s bed, which greatly affects the effect of the post-medication bath and causes waste of medication.

[0003] It can be seen from the article "Development and Application Effect Observation of Cow Nipple Liquid Protective Film" published by Zhou Qingmin, Heilongjiang Veterinary Science Research Institute, etc., that although its prescription can be made into a film-forming povidone-iodine solution, it uses Azone, ethanol and other organic solvents are used as volatile agents. Ethanol is volatile and easily takes away part of the heat and moisture from the skin, resulting in dry skin and affecting the protective effect; at the same time, ethanol has super penetrating power, which can penetrate into the cell body and cause dehydration , long-term use will make the skin of the cow’s nipple gradually lose its elasticity, and the medicated bath liquid containing ethanol is not suitable for use in the lactation period of the cow, and it is easy to remain in the milk, affecting the quality of the milk, and even alcohol-positive milk
