Glutaral and deciquam solution and preparation method thereof

Abstract

The invention belongs to the field of disinfectants and in particular relates to a glutaral and deciquam solution and a preparation method thereof. The glutaral and deciquam solution is prepared fromthe following components in percentage by weight: 3 to 8 percent of glutaral, 3 to 8 percent of deciquam, 0.5 to 3 percent of ethylhexylglycerin and the balance of de-ionized water. The glutaral and deciquan solution has no irritating odor, and high stability, and can keep a remarkable sterilization and disinfection effect after being stored for a long period; the glutaral and deciquam solution can be used for 100 percent killing escherichia coli, staphylococcus aureus, candida albicans, bacillus subtilis, pathogenic porcine reproductive and respiratory syndrome, porcine type 2 circovirus, foot-and-mouth disease virus and H5N1 subtype avian influenza virus under a suitable diluting degree.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to a glutaraldehyde decyl ammonium bromide solution and a preparation method thereof. Background technique [0002] Glutaraldehyde is a high-efficiency disinfectant. It acts on the sulfhydryl, hydroxyl, carboxyl, and amino groups of microbial proteins through its aldehyde groups to alkylate them, causing protein coagulation and causing microbial death. It has broad-spectrum, high efficiency, and low toxicity. , Low corrosion to metal and so on. However, using glutaraldehyde alone for sterilization and disinfection requires a long time, generally reaching 10 hours, and glutaraldehyde has poor stability and is irritating to mucous membranes, which brings a certain degree of inconvenience to producers and users. Decyl ammonium bromide is a double-chain quaternary ammonium salt double long-chain cationic surfactant, which has a broad anti-pathogenic spectrum, is effective against spores, m...

AI Technical Summary

Problems solved by technology

Among them, the mass concentration ratio of glutaraldehyde to decyl ammonium bromide is 5:1, the disinfectant with this ratio has a good bactericidal effect, the synergistic bactericidal effect of the two components can reach the best, the action time is short, the safety is good, and the metal Low corrosivity, but the disinfectant has a pungent odor, which brings unpleasant experience to users

[0004] Chinese patent application CN107568222A discloses a kind of compound glutaraldehyde decyl ammonium bromide long-acting disinfectant, described disinfectant is made up of glutaraldehyde, decyl ammonium bromide, deodorant, adhesive and water, and this disinfectant has Low irritating odor and long effective disinfection time, but the disinfectant has poor stability, and long-term storage will produce stratification, suspended solids, and turbidity, and the sterilization and disinfection effect will be reduced
