Hydrogen peroxide and nano-silver compound hand disinfectant and preparation method thereof

Abstract

The invention provides a hydrogen peroxide and nano-silver compound hand disinfectant and a preparation method thereof, and belongs to the technical field of disinfection. The hydrogen peroxide and nano-silver compound hand disinfectant comprises, by mass, 0-1.5% of hydrogen peroxide, nano-silver with an effective mass concentration of 50-100 mg / L, 0.1-2% of a stabilizer, 0.1-5% of a synergistic auxiliary agent, 0.05-5% of a moisturizing component and 1-10% of a plant skin care and sterilization component. ,According to the disinfectant, an alcohol-free formula is adopted, hydrogen peroxide and nano-silver are selected and compounded, the hydrogen peroxide and the nano-silver synergistically sterilize, the system is stable, the hydrogen peroxide is free of toxicity and residues after being decomposed, the nano-silver can form an antibacterial protective film to sterilize continuously and is free of irritation and damage to skin, the problems that the hand disinfectant in the market is non-irritant to the skin, small in damage and difficult to meet the requirements of refreshing, moisturizing and continuously and effectively resisting bacteria at the same time are solved, and the hand disinfectant has a wide application prospect in the technical field of disinfection.

Description

technical field [0001] The invention relates to a hydrogen peroxide and nano-silver compound hand disinfectant and a preparation method thereof, belonging to the technical field of disinfection. Background technique [0002] The inventor finds that there are at least the following problems in the prior art: [0003] The commonly used bactericidal ingredients in existing hand disinfection products mainly include volatile alcohols such as ethanol, isopropanol, and n-propanol, hydrogen peroxide complex alcohols, chlorhexidine, and plant-extracted bactericidal ingredients. Each has its disadvantages or limitations; the most common quick-drying alcohol-based disinfectants will take away moisture from the skin as they evaporate, and high concentrations of ethanol, n-propanol, or isopropanol will also break down sebum on the hands, and frequent use It will cause the user's hand skin to be degreased, dry, rough, or even peeled and chapped, causing pain and injury to the user; qua...

AI Technical Summary

Problems solved by technology

[0003] The bactericidal ingredients commonly used in existing hand disinfection products mainly include volatile alcohols such as ethanol, isopropanol, n-propanol, hydrogen peroxide complex alcohols, chlorine Hexidine and plant-extracted bactericidal ingredients, all kinds of hand disinfectants have their shortcomings or limitations; the most common quick-drying alcohol disinfectants will take away the moisture on the skin when they volatilize, high concentrations of ethanol, n-propyl Alcohol or isopropanol will also decompose the sebum of the hands, and frequent use will cause the skin of the user's hands to be degreased, dry, rough, or even peeled and chapped, causing pain and injury to the user; quaternary ammonium salt disinfectants are Its components are cationic surfactants, which are easy to foam and have many restrictions on compounding with other components; hydrogen peroxide hand sanitizers usually use hydrogen peroxide with a content of about 1% as the bactericidal concentration, but this concentration of hydrogen peroxide is single The composition is difficult to meet the requirements of hand disinfection, and it needs to be compounded with high-concentration alcohols or other disinfection ingredients to achieve the disinfection effect; currently there are hand disinfection products on the market that use silver ions as the main disinfection ingredient, but the silver ion itself loses one or multiple electrons, which have strong oxidative properties and cause certain damage to skin cells, and lose the antibacterial effect after sterilization, and cannot continue to effectively antibacterial

The hand sanitizers on the market have no irritation to the skin, little damage, refreshing, moisturizing and continuous effective antibacterial.

[0004] Comparative Document 1-A hydrogen peroxide silver ion compound disinfectant is described as a compound disinfectant of hydrogen peroxide and silver ion, by adding gelatin, Form gelatin-silver ion complexes to improve the stability of silver ions, but fail to solve the problem of long-term effective antibacterial effect of disinfectants
