Alcohol-Based Hand Sanitizer Combination of Eucalyptus Oil Extract against Aspergillus Niger Fungus

Abstract

The use of hand sanitizers as a protector for the general public has become a lifestyle today. Several types of hand sanitizer preparations can be found in various places. Alcohol is generally used as a microorganism-free material to clean the surface of the hands and clean the skin from various kinds of contamination including fungi. Alcohol in hand sanitizer preparations has various functions including killing fungi, neutralizing various types of microorganisms including fungi. Eucalyptus oil has antifungal properties and is an important component to inhibit the contamination of microorganisms that are harmful to the body such as fungi. This study aims to make an alcohol-based hand sanitizer preparation with a combination of eucalyptus oil extract that can clean the Aspergillus niger fungus. The results of this study, the measurement of pH is indicated by a value of 7 and for the specific gravity test the result is 0.8679 g/ml. The viscosity of the hand sanitizer of eucalyptus oil extract in this study had a value of 4.1 cP. Testing the cleaning power of hand sanitizer preparations with a contact time test of 60 seconds against Aspergillus niger. The results of testing the cleaning power of the Aspergillus niger fungus in hand sanitizer preparations with a contact time test of 60 seconds obtained the cleaning power of the Aspergillus niger fungus of 99.9%. hand sanitizer preparations with a combination of eucalyptus oil extract have very good effectiveness against the fungus Aspergillus niger and have good preparation quality in meeting the pH, specific gravity, and viscosity tests of hand sanitizer preparations.
