  • TOPICAL ANTIMICROBIAL MICROEMULSIONS WITH FLUORESCENT MATERIALS
    Publication number: 20220117859
    Abstract: A topical antimicrobial composition includes a lipophilic component including a surfactant system with an HLB value of less than 10; an amphiphilic component including an antimicrobial compound; an aqueous hydrophilic component; and a fluorescent material. The composition includes less than 10 wt % of lower monohydric alcohols based on the total weight of the composition. The composition is in the form of a microemulsion at room temperature with a disperse phase having droplets with a particle size of 5 nm to 400 nm.
    Type: Application
