Personal hygiene comes first! People always washed and bathed even the most ancient of our ancestors. However, the disinfecting potential of various substances was only discovered in the 19th century when Joseph Lister began researching the antiseptic properties of various materials, including carbolic acid, which was used to disinfect sewage pipes in London.
Hand sanitizers in their usual for us form appeared only in 1966, thanks to Lupe Hernandez, a student nurse from California, who invented and patented the alcohol-based gel. However, this product became available in regular stores only in 1988.
What other curious things about hand sanitizers will we learn today?
1. What even is a sanitizer?
Sanitizer is an antiseptic in the form of a gel on an alcohol or non-alcohol basis. The composition of the sanitizer also includes additional antibacterial agents that not only protect but also moisturize the skin of the hands. Thus, it kills most bacteria, without causing any significant harm to the skin.
2. How does it work?
The alcohol in the sanitizer is super-effective and destroys various bacteria and viruses quite easily, but it’s never 99.9%, as advertised. In real life, getting rid of all the germs will not work. Aside from that, sanitizer works best when there is no visible dirt on the hands. For example, if you washed your hands and then treated them with an antibacterial gel.
