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. Do you need full spectrum protection against mold and yeast in your formulations?
