Problems solved by technology

However, chlorine-containing disinfectants have obvious irritating effects on human respiratory mucous membranes and skin, and severe cases cause chlorine gas poisoning; they have a corrosive effect on metal objects and natural fiber textiles, and have a bleaching effect on pigments. Extensive use will also pollute the environment; Oxyacetic acid is flammable, explosive, strong oxidizing, strong corrosive, strong irritant, and can cause burns to the human body
Therefore, in order to make up for the shortcomings of existing disinfectants that are harmful to the environment and human health, it is urgent to develop a special disinfectant for funerals that is efficient, low-toxic, environmentally friendly, and in line with the hygienic characteristics of funeral places, so as to protect the health of funeral workers and create Hygienic and comfortable working environment

Embodiment 1

[0020] Embodiment 1: neutralizer identification test

[0021] The test strains were Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 25922) and Candida albicans (ATCC 10231), and 6 parallel groups were set up, and the neutralizer identification test was carried out according to the suspension quantitative test procedure. Judgment of the results: Group 1 has aseptic growth or the number of bacteria is far less than that of Group 2; the number of bacteria in group 2 is significantly less than that of groups 3, 4, and 5; the number of bacteria in groups 3, 4, and 5 is similar, and the error rate is ≤ 10% ; Group 6 grew aseptically. It shows that the selected neutralizer and its concentration are appropriate, and the test is repeated 3 times.

[0022] Tests have shown that with phosphate buffer containing 4g / L lecithin, 45g / L Tween-80, and 10g / L glycine, the residual effect of the disinfectant on the test bacteria can be effectively neutralized. It has no adverse effect...

Embodiment 2

[0026] Embodiment 2: Bacteria (fungus) quantitative killing test

[0027] In order to evaluate the killing effect of the disinfectant of the present invention on microorganisms, according to the disinfection technical specification (2002 edition), the quantitative killing test of bacteria and the killing test of fungi were carried out respectively. The strains were Staphylococcus aureus ATCC6538, Escherichia coli ATCC 25922 and Candida albicans ATCC 10231. According to the specified use concentration and action time, repeat the test 3 times.

[0028] The result shows (table 2), when using disinfectant of the present invention to dilute 300 times, the time of action is 3min, suspension quantitative killing test, to the killing logarithmic value of each test of Staphylococcus aureus, Escherichia coli, Candida albicans. ≥5.00, it is judged as qualified for disinfection.

[0029] Table 2 disinfectant of the present invention is to the killing effect of bacterium (fungus)

Embodiment 3

[0032] Embodiment 3: stability test

[0033] Accelerated test: Place the original sample in a constant temperature box at 54°C to 56°C for 14 days, keep the relative humidity ≥ 75%, and test the antibacterial or bactericidal performance of samples.

[0034]Experimental result shows (table 3), use disinfectant of the present invention to dilute 200 times, the time of action is 3min, the suspension quantitative killing rate to Staphylococcus aureus can reach 100%; Use disinfectant of the present invention to dilute 400 times, time of action 3 minutes, the average killing rate of Escherichia coli and Candida albicans can reach 100%. Accelerated test at 54°C shows that its bactericidal rate or bacteriostatic rate can reach the specified standard value, and the bactericidal or bacteriostatic effect of the product is valid for at least 1 year when stored at room temperature. Illustrate that the disinfectant of the present invention has strong stability.

Abstract

The invention relates to a high-efficient, low-toxicity and environmental-friendly disinfector for remains and a preparation method thereof. The disinfector comprises the following components in percentage by mass: 0.4-0.6 percent of o-phthaldialdehyde, 0.05-0.1 percent of benzalkonium bromide, 0.2-0.5 percent of polyethylene glycol monooleyl ether, 2-10 percent of ethanol, 1-3 percent of isopropanol, 0.25-1.5 percent of organic acid, 0-0.3 percent of essence and 84-96 percent of distilled water. As demonstrated by a stability test, a disinfection microorganism test (including a neutralizer appraisal test) and a funeral parlour field disinfection trial, the disinfector provided by the invention has the advantages of good stability, high sterilization efficiency, no stimulation or corrosivity, etc., and can be used for disinfecting the remains, relevant environments, air and general object surfaces.

Description

technical field [0001] The invention relates to a chemical disinfectant, in particular to a high-efficiency and low-toxicity corpse disinfectant applicable to corpses and related environments and a preparation method thereof. Background technique [0002] Funeral places are special public places, and remains are the main source of pollution. Various pathogenic microorganisms carried by the remains, such as saprophytic bacteria and (conditional) pathogenic bacteria, will spread in various processes of funeral services, causing microbial contamination in the air, surfaces of objects, surfaces of remains, and employee hands. Corps workers, embalmers and cosmetic workers, and cremation workers have direct contact with corpses every day, and face the danger of being infected by blood and body fluids from corpses with infectious bacteria. The standard GB 19053-2003 stipulates the safety limit of pathogenic bacteria in various funeral places, and requires that the remains should b...
