Microbial testing of cosmetics and pharmaceuticals.

We have obtained permits for cosmetics manufacturing and cosmetics manufacturing and sales, and we will conduct tests in testing facilities (BSL2) in accordance with the Pharmaceutical and Medical Device Act.

In standard testing, total viable count, coliforms, E. coli, and Staphylococcus aureus are tested as a set. Upon request, it is also possible to add Pseudomonas aeruginosa, Salmonella, Vibrio parahaemolyticus, Campylobacter, Bacillus cereus, O157, MRSA, periodontal pathogens, Legionella, Serratia, etc. Measurement of antibacterial activity using the above microorganisms (inhibition zone, mixed culture) is also possible. The method for calculating the coal tar coefficient involves varying the concentration of the antibacterial substance in several ways and varying the reaction time with the microorganisms at several points, performing a mixed culture that combines concentration and reaction time. This allows us to determine the relationship between the concentration of the antibacterial substance and the reaction time, enabling the assessment of the immediate and sustained efficacy of the antibacterial agent. Preservative efficacy testing (compliant with JP, USP, EP) involves dropping five types of microorganisms into pharmaceuticals, etc., and measuring the microbial count after a certain storage period. This method investigates the effectiveness of microbial control when microbial contamination occurs in the relevant pharmaceuticals, etc. Aseptic testing determines whether there is no microbial contamination in cosmetics, pharmaceuticals, etc.
