Composite double-chain quaternary ammonium salt antiseptic solution and usage method and application thereof

Abstract

The invention provides a composite double-chain quaternary ammonium salt antiseptic solution, which comprises double-chain quaternary ammonium salt, single-chain quaternary ammonium salt and o-phthalaldehyde, the double-chain quaternary ammonium salt is dimethyldioctylammonium chloride or bis-decyl-dimethyl ammonium chloride, and the single-chain quaternary ammonium salt is dodecyl dimethyl benzyl ammonium chloride; preferably, the weight of double-chain quaternary ammonium salt is 0.04-0.06%, the weight of single-chain quaternary ammonium salt is 0.20-0.30%, and the weight of o-phthalaldehyde is 0.4-0.7%. The composite double-chain quaternary ammonium salt antiseptic solution also comprises one or more of a nonionic surfactant, an inorganic anti-interference agent and a synergist. The invention also provides an application method of the composite double-chain quaternary ammonium salt antiseptic solution and its application. The composite double-chain quaternary ammonium salt antiseptic solution has the advantages of fast sterilization and good disinfection effect , health, safety, no toxic and side effect, and good stability, has no deformation effect on a dental impression, guarantees size stability of dental impression, and is adapted to 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
