In the ASTM E2755-15 standard developed by the American Society for Testing and Materials (ASTM), healthcare professionals can determine the activity of hand lotions (hand lotions, hygienic hand lotions, hand disinfectants or hand antiseptics) against temporary microbial skin flora on hands after a single application and after repeated applications. provide a test method foris up. This test method must be applied by experts with microbiology training in facilities designed and equipped to work with potential infectious agents at the biosafety level.
Hand hygiene is considered as one of the most important measures to prevent the spread of infectious microorganisms. Hand lotions reduce the microbial load on hands without the use of soap and water and are an important tool in hand hygiene practice. Alcohol-based hand lotions are formulated to be applied to dry hands, rubbed dry and not rinsed.
The test method described in the ASTM E2755-15 standard is designed to evaluate hand lotions for effectiveness in eliminating bacteria from contaminated hands. This standard is designed as an alternative to the ASTM E1174 standard, which is designed to evaluate antimicrobial hand washing agents that are foamed and rinsed with the help of water.
Insufficient drying of the hands after contamination dilutes the test material and loses some of its effectiveness.
In this test method, applying a small volume of high titer test bacteria suspension to the hands ensures that the skin is completely dry before the test material is applied.
This test method is used to test all types of hand rubs, including gels, rinses, sprays, foams, and wipes, when used according to label instructions at the in-use doses. Sensitivity to biocides varies between different bacterial species and varies significantly between gram-negative and gram-positive organisms. This test method offers the option of using a gram negative bacteria (serratia marcescens) or a gram positive bacteria (staphylococcus aureus) as the test organism. Serratia marcescens is used as a test organism in both ASTM E1174 and ASTM E2276 standards.
