CHALLENGE TESTING REVEALS THAT 2% LEUCIDAL LIQUID IN A CREAM BASE IS ABLE TO SUCCESSFULLY INHIBIT MICROBIAL GROWTH. SAMPLES WERE INOCULATED WITH S. AUREUS, E. COLI, P. AERUGINOSA, C. ALBICANS, A. NIGER, K. PNEUMONIAE, B. CEPACIA. FOLLOWING 28 DAYS OF INCUBATION SAMPLES WERE THEN RE-INOCULATED FOR AN ADDITIONAL 28 DAYS. MINIMUM INHIBITORY CONCENTRATIONS (MIC) WERE DETERMINED USING A STANDARD AGAR DILUTION METHOD. A VARIETY OF BACTERIA AND FUNGUS WERE TESTED TO EVALUATE THE ABILITY OF LEUCIDAL® LIQUID TO PROTECT AGAINST MICROBIAL CONTAMINATION. THE RESULTS INDICATE THAT LEUCIDAL® LIQUID CAN PROVIDE EFFECTIVE PROTECTION FOR CERTAIN COSMETIC SYSTEMS.
