Problems solved by technology

However, the acidity of this iodic acid mixed solution is relatively strong, so it cannot be directly used for direct disinfection of human body and other animal bodies.
[0009] For iodine-containing disinfectants, generally when the product is stored for a long time, the composition changes, mainly manifested as a decrease in the content of elemental iodine, which affects the overall stability of the formula and also causes fluctuations in the disinfection and sterilization effects to a certain extent

preparation example Construction

[0068] The preparation method of the iodine-containing disinfectant of the present invention is based on the relationship of solubility so that the material is prepared on the principle of being easy to dissolve.

[0069] Or for the above-mentioned materials, if there is a material with a balanced component, it can be dissolved and prepared according to the above-mentioned solubility principle; for a material that does not reach the equilibrium composition under the preparation temperature, it can also be prepared according to the above-mentioned solubility principle. Afterwards, it is enough to achieve the above-mentioned disinfectant components with balanced composition under certain conditions, and the certain conditions are generally conditions of a temperature higher than room temperature and / or a pressure higher than normal pressure.

[0070] Each component in the iodine-containing disinfectant formula of the present invention interacts, couples with each other and is ind...

Abstract

The invention discloses an alcohol-free iodine-containing disinfectant with high component stability and a preparation method of the alcohol-free iodine-containing disinfectant. The iodine-containing disinfectant comprises the following components by weight: 0.1-10% of elemental iodine, 0.1-10% of iodide, 0.01-2% of iodic acid and / or iodate, 0.1-20% of carboxylic acid, 60-90% of water, 0.01-1% of iron (Fe <3+>) salt, and 0.01-1% of ferrous (Fe<2+>) salt. The iodide is composed of iodine negative ions and hydrogen ions or metal cations or ammonium ions or quaternary ammonium ions. The iodine-containing disinfectant has the advantages of simple preparation method and stable component content after long-term storage.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to an alcohol-free iodine-containing disinfectant with high component stability. Background technique [0002] Iodine has been used for body sterilization for more than 100 years, and many iodine-containing disinfectant formulations have been developed to meet different use occasions. Iodine disinfectant has low tissue toxicity and is widely used in clinical, sanitation, daily life, livestock and poultry breeding, aquaculture, public places and drinking water. Before iodophor was invented, tincture of iodine (ethanol-containing iodine disinfectant, or iodine) was widely used in disinfection occasions, but because of the irritation of alcohol and the need for further deiodination after use, it is now being gradually irritated Smaller iodophor disinfectants are replaced; iodine glycerol is less irritating than iodine tincture (iodine), but there is also the problem of irritating and caus...
