Persistence, the continuance of bactericidal or bacteriostatic activity for some period of time after product use, may be a very desirable attribute for topical antimicrobial products such as antibacterial towelettes, barrier creams and liquid/gel products. The testing methodology, per ASTM E1882, uses the forearms of human subjects as the product application site. This test method determines the persistence of test formulations, as measured by the inhibition of a test organism on an agar surface exposed to test sites on human skin.
