ASTM E2276 Test Method
This test method is carried out on a group of adult subjects who have given informed consent and whose hand skin is free of any visible damage. The subjects are required to avoid the use of any products containing antimicrobial agents for one week before the test.
A specific amount of test suspension is applied on a demarcated area on each finger pad and then allowed to dry.
The contaminated fingertips are then exposed to the control ( hard water) and test ( product sample) for the specified contact time.
In the next step, surviving microorganisms from the fingerpads are eluted and the viable counts are determined.
Reductions in the numbers of viable bacteria from the control and product samples are calculated and analyzed for antibacterial efficacy.
