Compound double-chain quaternary ammonium salt disinfection solution as well as utilization method and application thereof

Abstract

The invention provides a compound double-chain quaternary ammonium salt disinfection solution. The compound double-chain quaternary ammonium salt disinfection solution comprises a double-chain quaternary ammonium salt and a single-chain quaternary ammonium salt, wherein the double-chain quaternary ammonium salt is bisoctyl dimethyl ammonium chloride or didecyl dimethyl ammonium chloride; and the single-chain quaternary ammonium salt is dodecyl dimethyl benzyl ammonium chloride. Preferably, the compound double-chain quaternary ammonium salt disinfection solution comprises 0.04wt%-0.06wt% of the double-chain quaternary ammonium salt and 0.20wt%-0.30wt% of the single-chain quaternary ammonium salt. The compound double-chain quaternary ammonium salt disinfection solution further comprises one or more of a non-ionic surfactant, an inorganic anti-interference agent and a synergist. The invention further provides a utilization method and application of the compound double-chain quaternary ammonium salt disinfection solution. The compound double-chain quaternary ammonium salt disinfection solution provided by the invention has a high sterilization speed and a good disinfection effect; the compound double-chain quaternary ammonium salt disinfection solution is sanitary and safe, has no toxic or side effect and has good stability; and the solution basically has no deformation effect on a dental impression die, guarantees the size stability of the dental impression die and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of disinfectant, in particular to the technical field of quaternary ammonium salt disinfectant, in particular to a composite double-chain quaternary ammonium salt disinfectant and its use and application. Background technique [0002] The oral cavity is a multi-bacterial ecosystem. Because the impression is in direct contact with the patient's saliva and blood, the viruses and microorganisms carried by it can cause cross-infection during the model making process. However, due to the characteristics of impression materials, such as alginate, which absorb water and swell in water, and shrink when water overflows in the air, the impression is easily deformed after being soaked in water vapor, disinfectant solution, and ultraviolet disinfection. Therefore, the disinfection of impressions has become an important problem faced by oral medical workers in recent years. [0003] Quaternary ammonium salt disinfectant...

AI Technical Summary

Problems solved by technology

[0006] But for a single double-chain quaternary ammonium salt, the types of microorganisms it can kill are still not comprehensive enough, and the disinfection effect is still not ideal enough. Therefore, it is desired to provide a compound double-chain quaternary ammonium salt disinfectant, which is fast in sterilization and good in disinfection effect , hygienic, safe, non-toxic and side effects, good stability, and basically no deformation effect on dental impressions, ensuring the dimensional stability of dental impressions
