Novel disinfectant prepared from quaternary ammonium salt and alcohol

Abstract

The invention discloses novel disinfectant prepared from quaternary ammonium salt and alcohol. The disinfectant is prepared from alcohol, quaternary ammonium salt, a corrosion inhibitor, a chelating agent and water. The novel disinfectant can be used for killing pathogenic entero becteria and staphylococcus aureus within one minute, wherein the killing log value is larger than 5; the novel disinfectant can be used for killing candida albicans and pseudomonas aeruginosa within three minutes, wherein the killing log value is larger than 5; the novel disinfectant further has an effect of killing aspergillus niger. The novel disinfectant disclosed by the invention is washing-free, has no corrosion to metal products, can be widely applied to sterilizing in the fields such as appliances and food, is free of toxic action on human bodies and animals and suitable for sterilizing the skin of the human bodies and animals, and has a long-lasting bacteriostatic action. When used for sterilizing common articles, the novel disinfectant can replace quaternary ammonium salt disinfectant to shorten the sterilization time to one minute, can take the place of alcohol and iodine disinfects when used for sterilizing the skin, can keep the antibacterial effect for a long time and can effectively protect the skin part from secondary pollution.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a novel disinfectant prepared by using quaternary ammonium salt and alcohol. Background technique [0002] According to "GB26373-2010 Hygienic Standards for Alcohol Disinfectants", the ethanol content in ethanol disinfectants is 70%-80%. Usually, ethanol disinfectant has high ethanol content and strong volatility, and the volatile gas is prone to combustion accidents when it encounters an open flame. It has been reported that when the patient was operated with ethanol disinfection, the ethanol disinfectant encountered an electric spark from an electric scalpel and a burn accident occurred. High-concentration alcohol disinfectants may also be extremely sensitive to human skin. 70%-80% ethanol or 65%-80% isopropanol disinfectant has good sterilization effect, but its use and storage have non-negligible risks. Ethanol or isopropanol disinfectant is easily affected by the environment during trans...

[0004] The development of quaternary ammonium salt disinfectants has gone through multiple stages, and the bactericidal activity is constantly improving, but it still takes a long time to achieve the ideal disinfection effect; in addition, quaternary ammonium salt disinfectants usually contain chloride ions or bromide ions, and long-term use is harmful to equipment. It is corrosive to a certain extent; quaternary ammonium salt disinfectant is sensitive to metal ions such as calcium
