Antimicrobial Activity of Biocompatible Microemulsions Against and Herpes Simplex Virus Type 2.

Background: Microemulsions (MEs), which consist of oil, water, surfactants, and cosurfactants, have recently generated considerable interest as antimicrobial agents.

Objectives: To determine the antifungal and antiviral activities of three ME formulations (MEa, MEb, and MEc) that differ in their hydrophilicity.

Methods: The ME formulas were produced by mixing different fractions of Tween 80, Span 20, ethanol, oil, isopropyl myristate, and distilled water.
