HISTORY

THE EARLY ROOTS OF HAND SANITIZER

ANCIENT HAND SANITIZER - B.C

This was also known beforehand as hand sanitizer; people knew that alcohol could sterilize. Alcohol arose from Al Kohl, and an antimony term used 5,000 years ago by ancient Egyptians to cure eye infections. Earlier, more than a thousand years later, you will find parallels to the use of alcohol to heal wounds by medical doctors like Claudius Galen (131-201 AD) and Guy de Chauliac (1363).

ALCOHOL AS A MODERN ANTISEPTIC - 1800 -1900S

While used throughout history, scientific evidence of the antimicrobial properties of alcohol only came in 1875. This was a highly debated subject at this point since bacteria can be destroyed, but not by spores. This continued after alcohol was introduced into surgery in 1888 by some well-known doctors recommending alcohol for pre-operative hand disinfection and surface disinfection. During the 1930s, ethanol was the preferred antiseptic skin during hospitals.
