Compound quaternary ammonium salt disinfectant liquid and preparation method thereof

Abstract

The invention relates to a compound quaternary ammonium salt disinfectant liquid, which is prepared by compounding single-double chain quaternary ammonium salt benzalkonium bromide and didodecyl dimethyl ammonium chloride used as raw components and povidone-iodine, dissolving the three components by using ethanol with the concentration of 95 percent as a solvent and mixing evenly. The compound quaternary ammonium salt disinfectant liquid comprises the following components by weight percent: 0.2-0.6 percent of benzalkonium bromide, 5-15 percent of didodecyl dimethyl ammonium chloride, 5-13 percent of povidone-iodine, 25-35 percent of ethanol with the concentration of 95 percent, and the balance of purified water. The implementation steps are as follows: (1), weighing benzalkonium bromide, didodecyl dimethyl ammonium chloride and povidone-iodine according to the proportion and placing into a container; (2), weighing the ethanol with the proportional concentration of 95 percent into the container; and (3) sufficiently and evenly mixing the components in the steps (1) and (2) to be dissolved, fixing volume by using purified water, separately packaging and checking according to the routine, and warehousing the qualified products. The invention has the advantages of simple preparation, safe use, no toxicity, no pollution for environment, stable medicine property and obvious effect.

Description

technical field [0001] The invention relates to a compound disinfectant and a preparation method thereof, in particular to a compound quaternary ammonium salt disinfectant and a preparation method thereof. Background technique [0002] At present, the most widely used veterinary disinfection drugs produced, operated and used in my country are mainly four categories: compound phenols, iodine, quaternary ammonium salts and chlorine preparations. There are still many problems in the practical application of veterinary disinfectants, such as ignoring the removal of organic matter such as feces, feed residues, body surface shedding in livestock and poultry houses; thinking that drinking water disinfectants are harmless to livestock and poultry and increasing the concentration at will, causing loss; think that using warm boiled water as a solvent can increase the disinfection effect of all disinfectants; it is impossible to cross-apply multiple types of disinfectants, resulting in...

AI Technical Summary

Problems solved by technology

Tests have proved that simply using a single chemical disinfectant cannot meet the requirements of a good biosafety plan; a single disinfectant has some inherent defects: weak ability to penetrate organic matter, greatly affected by ambient temperature, high concentration, and increasingly Serious security issues, loss of price advantage, etc.
