The bacteria in the life are everywhere, so the disinfectant plays a big role. Usually, people use disinfectant to wash their hands or wash things. It is very troublesome to wash them repeatedly. But now, the market has introduced a hand-free disinfectant, which is very practical. Do you know the principle of hands-free disinfectant ? The principle of hand sanitizer is: Common ingredients for disposable disinfectant are alcohol, peracetic acid and chlorhexidine. Alcohol is not only the main ingredient of many hand sanitizers, but also the main ingredient of many wet wipes. The main role of alcohol is to kill bacteria, and its concentration is usually controlled at around 70%. Alcohol with a concentration of more than 80% is not suitable as a disinfectant, because high concentration of alcohol will cause the bacterial protein to coagulate, forming a protective film, hindering the further penetration of alcohol into the depth of the bacterial cells, and reducing the bactericidal effect. Since alcohol is easily volatilized, there is no residue on the hands after use, so it is not necessary to rinse with water. Instructions: 1. Surgical hand washing and disinfection: Wash hands with soap solution according to the standard, rinse with water, dry with a sterile towel, then apply the original solution evenly to the hands and forearms, each arm is about 5~10ml, forcefully approx. Apply for 1 minute until the surface is dry. 2, hand sanitation: first use the right amount of this product (about 3ml) to wet the hands, rub for about one minute, until the liquid covers the entire surface to dry. 3, general skin disinfection: take the appropriate amount of this product applied or sprayed on the skin surface to moist, for a minute, naturally dry. I would like to introduce you to the principle of hands-free disinfectant . I hope everyone can understand the importance of disinfection and strengthen their health and hygiene awareness.
