The use of alcohol gel in hand antisepsis and surface disinfection procedures is a common practice in health institutions. With the Covid-19 pandemic, it became an habit for people to use it. The objective of the present study was to analyze the physical-chemical characteristics as well as the microbiological efficacy of different brands of gel alcohol sold in pharmacies during the Covid-19 pandemic period. The physical-chemical analyzes comprised the alcohol concentration, color, appearance, pH value and resistance to centrifugation, and for an analysis of the microbiological effectiveness, a surface disinfection test was performed against a standard Gram-negative bacteria Salmonella typhimurium (ATT 14028). The studied samples are within the expected standards for the physical-chemical aspects as well as showing efficiency in the elimination of bacteria on contaminated surfaces.
