VISCOUS TOPICAL ANTIMICROBIAL COMPOSITIONS

摘要

Provided are antimicrobial compositions especially suited for application to the epidermis, e.g., hands, arms, legs, face, scalp as well as other body areas which preferably exhibits an acidic pH. The compositions exhibit at least 3 log kill efficacy, preferably at least 4 log kill efficacy at 60 seconds contact time of at least two, preferably at least three and most preferably at least four of microorganisms selected from the group consisting of: S. aureus, E. coli, P. aeruginosa and E.hirae, according to the protocols of prEN 12054. The compositions are largely aqueous and desirably exhibit a viscosity of at least 500 cPs at 25°C, and desirably exhibit a pH of 4.5-5.5. Methods for the manufacture of the topical antimicrobial compositions and methods for their use are also disclosed. The antimicrobial compositions also find utility in the treatment of inanimate hard surfaces and inanimate soft surfaces.
