Composite quaternary ammonium salt disinfectant and preparation method thereof

Abstract

The invention provides a composite quaternary ammonium salt disinfectant and a preparation method thereof. The composite quaternary ammonium salt disinfectant is prepared from dioctyl dimethyl ammonium chloride, dodecyl dimethyl benzyl ammonium chloride, lauryl glucoside, glacial acetic acid, a guanidine disinfectant, a surfactant, composite potassium iodate, chitosan hydrochloride, dibromohydantoin, hydrogenated hyperbranched polyolefin, moxifloxacin, allicin and beta-dextran palmitate as raw materials. Staphylococcus aureus, escherichia coli and candida albicans can be effectively inhibitedand killed, the killing efficiency of the composite quaternary ammonium salt disinfectant can be improved, so that the composite quaternary ammonium salt disinfectant has high killing durability. In addition, the composite quaternary ammonium salt disinfectant is used for disinfection of equipment and instruments, especially medical instruments, and the disinfection effect of the composite quaternary ammonium salt disinfectant on the medical instruments can reach the disinfection effect of glutaraldehyde disinfection products which are main products for disinfection of the medical instrumentsat present, and the composite quaternary ammonium salt disinfectant cannot damage objects to be disinfected, has no pollution to the environment and does not corrode metal utensils and the like.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to a compound quaternary ammonium salt disinfectant and a preparation method thereof. Background technique [0002] Medical devices are related to the health of patients, and the requirements for disinfection of devices are higher, and the requirements for sterilization are stricter. The existing disinfectants for medical instruments are generally required to have the following characteristics: 1. The disinfectant does not corrode the equipment and can be used for a long time; 2. It has a good disinfection effect and can quickly kill germs on the instruments; 3. It is non-toxic and pollution-free. It will not cause physical harm to patients; 4. The disinfectant will not cause harm to operators. [0003] At present, the representative products of strong bactericidal products in the domestic disinfection product market mainly include the following categories: 1. Chlorine-based disinfecta...

AI Technical Summary

Problems solved by technology

[0003] At present, the representative products of strong bactericidal products in the domestic disinfection product market mainly include the following categories: 1. Chlorine-based disinfectants: such as 84, bleaching powder, etc., the main active ingredient is organic chlorine, which has broad-spectrum and high-efficiency sterilization, strong irritation, and corrosiveness Strong, easily affected by organic matter, pollutes the environment, and can produce toxic and side effects on the human body

2. Phenolic disinfectants: such as phenol, Lysol, etc., have good bactericidal effect, strong irritation, heavy odor, are easily affected by organic matter, pollute water and the environment, and can produce toxic and side effects on the human body

3. Aldehyde disinfectants: such as glutaraldehyde, which have a better disinfection effect on medical equipment, but also have a corrosive effect on the disinfected products

At present, most of the quaternary ammonium salt disinfection products in the domestic disinfection product market are single preparations or simple so-called compound products of "quaternary ammonium salt + quaternary ammonium salt", and their bactericidal effect is not good.
