The safety of disinfectant use includes toxicity to human body, corrosiveness of articles, compatibility of materials and flammability, etc. Disinfection products should be non-toxic, and their toxicity involves carcinogenic, teratogenic, mutagenic, and reproductive toxicity.
The toxicological experiments of the surface sanitizer are usually done with animals, insects, fish or cell lines. The result is often high-dose and long-term exposure. More importantly, when inferring the experimental results of animals, insects and cell lines to humans, there are still certain problems. It cannot be simply said that mammals have toxic reactions, and we humans will certainly have reactions; of course, it is possible that humans have toxic reactions to certain types of disinfectants, while mammals have no response. There are various types of disinfectants, The United States divides the toxicity levels of disinfectants into: dangerous, warning, cautious, and non-toxic.
Flammability is also a concern. For example, the US CDC guidelines clearly point out that considering the flammability, alcohols (without compound formulations, such surface disinfectants have very low alcohol content) should not be used in large areas.
The label of the disinfectant should contain information about the user's choice of PPE, instructing the user about the adverse effects when exposed to the disinfectant for a long time, including toxic reactions, bleaching of the user's fabric, and allergic reactions to the human body. Therefore, medical institutions should provide users with the minimum PPE based on the product IFU.
Another convenient problem is that the use of a water-soluble disinfectant is convenient to prepare and can ensure the effective ingredients of the disinfectant. Disinfectant application is wild. Disinfectant products come in a variety of styles, such as powders, liquids and tablets; different quantities of wet wipes are packaged to ensure that they can be used up in the shortest time after opening; and wet wipes with different carrier sizes are suitable for the surface disinfection of different sizes of items.
In addition, the material characteristics of the carrier non-woven fabric used for disinfection of wet wipes should also be suitable for surface disinfection. If the effective components of surface disinfectant cannot be adsorbed, in order to avoid affecting the concentration of disinfection solution in the process of application, at the same time, the fiber material of non-woven fabric does not antagonize the activity of disinfectant.
It has good water absorption performance, so it can be used in a larger area, thereby reducing the cost of wet wipes. The non-woven fabric is not easy to tear or fall off, which can avoid the production of additional "dust" during the wiping process. After the surface moisture dries up, these floccules falling from the non-woven fabric will rise with the airflow and become airborne carrier of microorganisms.
