Can Hand Sanitizers Kill Viruses?

During the epidemic, sanitary disinfection products became popular. Especially with "disinfection, sterilization" and other words of the product, become a lot of people's first choice.

Many people commute with hand sanitizers, but do these products really have a "sanitizing" effect?

Many people regard hand sanitizer as a "lazy necessity" and take it out and wipe it down to avoid the hassle of washing hands. There are a wide variety of hand sanitizers on the market, with a wide variety of options to choose from.

However, not all of these hand sanitizers are effective against novel coronavirus.

Novel coronavirus can be inactivated by alcohol, and people are snapping up alcoholic products. But many people overlook the fact that alcohol must reach a certain concentration to be effective.

Before the outbreak, many hand lotions on the market contained less than 75 percent alcohol, and some products were only "alcoholic", ranging from 10 to 30 percent. Such hand sanitizer is not enough to have a good disinfection effect at ordinary times. It is far from enough to kill novel coronavirus.

Of course, the higher the alcohol, the better. According to the recommendations of the world health organization, 60% to 80% alcohol concentration is acceptable, but too much (90% to 95%) is not effective.

When buying, you can focus on the packaging, basically will mark the alcohol content, the best choice is "alcohol 75%±5%".

Chlorine-containing products are often found in hand lotion, and benzalkonium chloride and chlorine acetate have been identified as active ingredients.

Chlorhexidine, also known as chlorhexidine, is a low-efficiency disinfectant with good bactericidal effect and occupies a place in the field of sterilization, which can kill pathogenic bacteria in the intestinal tract, pyogenic coccus, pathogenic yeast and common bacteria of hospital infection. But in this case, chlorhexidine is an invalid ingredient that has been officially stamped, Ms. Li said.

Benzaldine chloride can kill viruses, but there is no evidence of efficacy against novel coronavirus. Thus, these two ingredients are effective against bacteria but not against novel coronavirus.

A lot of people eye, chemical disinfectant irritant is stronger, Chinese traditional medicine hand sanitizer does not irritate, safe, stable.

This lotion is usually made up of artemisia annua, honeysuckle, radix isatidis, atractylodes atractylodes, rhubarb, cortex magnolia, clove, mint and other traditional Chinese medicines and additives. In addition to sterilization, there are anti-inflammatory, antipruritic, deodorant effect.

These effects are based on the effects of the ingredients themselves, all of which have certain antibacterial effects. It has been clinically confirmed that the disinfectant prepared by this kind of traditional Chinese medicine has obvious bacteriostatic effect on staphylococcus aureus, staphylococcus albicans, escherichia coli, streptococcus and so on.
