Description

Hydrogen-rich water-containing hand-washing-free disinfection gel and preparation method thereof

Technical Field

The invention relates to the technical field of disinfectant preparations, in particular to a hand-washing-free disinfectant gel containing hydrogen-rich water and a preparation method thereof.

Background

In various organs of a human body, hands are the most frequent parts of the human body contacting the outside, and during daily activities of people, the hands can inevitably contact microorganisms and even pathogenic microorganisms. The warm and moist environment of the hand provides proper conditions for the growth and the propagation of microorganisms, and the microorganisms not only can possibly infect the hands, but also can be spread to other people by means of shaking hands, contacting articles and the like.

The hand disinfection can kill most microorganisms on the hand, so that the number of common pathogenic microorganisms is reduced to a safe level, and a proper hand washing disinfection product can effectively kill a plurality of pathogenic microorganisms on the hand skin.

The common hand sanitizer has limited sterilization effect, only 20-30% of bacteria can be taken away under the action of water flow in the hand washing process, and highly pathogenic germs such as staphylococcus aureus, candida albicans and the like adhered to hands cannot be killed, and meanwhile, the water-based hand sanitizer is easy to spray and drip when used, is poor in use experience, and is difficult to meet outdoor use requirements; the broad-spectrum bactericidal property of the hand washing and disinfecting product still needs to be improved.

With the progress of medical research on hydrogen, people have gradually come to recognize the important role of hydrogen in removing free radicals and resisting oxidation, and hydrogen-rich water has attracted more and more attention as a hydrogen-rich product which can be taken as drinking water for a long time, but no report is found on a hand washing and disinfecting product containing hydrogen-rich water.

Therefore, the development of the non-washing hand disinfection gel containing hydrogen-rich water, which has strong bacteriostatic ability, is safe to skin and has no stimulation, is of great significance.
