Strong-stability film-forming nipple protecting liquid for cows and preparation process thereof

Abstract

The invention belongs to the technical field of drug preparation and in particular relates to strong-stability film-forming nipple protecting liquid for cows and a preparation process thereof. The liquid is characterized by comprising the following components by weight percent: 1-10% of povidone-iodine, 1-15% of film-forming agent, 0.5-5% of stabilizing agent, 0.1-4% of protective agent, 1-5% of antifreezing agent, 5-10% of surfactant, 5-20% of phosphate buffer and purified water. The preparation process comprises raw material treating, mixing, activating, filtering, PH value regulating, volume metering, subpackaging and sealing. After the cows are milked and before the nipple catheter is not closed, pathogenic bacteria intrude into the nipples very easily; therefore the film-forming nipple protecting liquid should be used instantly after milking the cows to quickly form a layer of film on the nipples to isolate the outside pathogenic microorganisms, thus reducing the incidence rate of mastitis, simultaneously protecting the nipples from frostbites and suncrack and ensuring stability of the povidone-iodine solution.

Description

technical field [0001] The invention belongs to the field of medicine preparation, in particular to a highly stable film-forming protective emulsion for dairy cows and a preparation process thereof. Background technique The treatment of cow mastitis is more and more difficult to cure, and people pay more and more attention to the prevention of mastitis. Add some effective traditional Chinese medicine preparations for prevention during the feeding process of dairy cows. Recently, people have begun to disinfect the teats of dairy cows to prevent mastitis, and teat dipping liquid products have also begun to appear. Povidone-iodine film-forming nipple dips have appeared on the market. Povidone-iodine is recognized as a new type of high-efficiency, broad-spectrum, less irritating, non-toxic and side effects, no residue, and no drug resistance fungicide. It has a strong killing effect on Staphylococcus aureus, Pseudomonas aeruginosa, hepatitis B virus, HIV, Trichomonas vagina...
