Povidone iodine solution and preparation method thereof

Abstract

The invention relates to a povidone iodine solution and a preparation method thereof. 100 g of povidone iodine solution is mainly prepared from, by weight, 0.1-3 g of elementary substance iodine, 1-5g of PVP, 1-10 g of polyvinyl alcohol, 2-10 g of polyurethane, 0.1-5 g of sodium alginate, 0.2-5 g of organic acid, 5-35 g of surfactant, 1-3 g of plasticizer and the balance water and pH adjuster. The povidone iodine solution is safe, reliable, high in stability and good in film-forming effect, formed film is high in toughness and does not easily fall off, the drug efficacy is durable, the antibacterial effect is ensured, a lot of labor and drug application cost can also be saved at the same time, and the povidone iodine solution is suitable for large-scale dairy cattle breeding 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 of Nipple Liquid Protective Film and Observation of Its Application Effect" 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 takes away the heat and moisture of the skin, resulting in dry skin and affecting the protective effect. Use will make the skin of the cow’s teat 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 may appear.
