Broth Microdilution Minimum Inhibitory Concentration (MIC) Test against Candida albicans
Standardized broth microdilution method to determine the MIC of a test substance against Candida albicans following CLSI M27.
Sample Requirement:
Test antimicrobial agent (e.g., extract or compound) 0.01 g
Sample Count:
Accepts exactly 1 sample.
Broth Microdilution Minimum Inhibitory Concentration (MIC) Test for Propionibacterium acnes
Broth microdilution method to determine MIC of test antimicrobial agents against P. acnes (now Cutibacterium acnes) under anaerobic conditions.
Sample Requirement:
Test antimicrobial agent (pure compound or stock solution), 50 mg
Sample Count:

Disk Diffusion Assay for Antimicrobial Activity against Escherichia coli
Agar-based method measuring inhibition zone diameters around disks impregnated with test substance on E. coli lawn to assess antimicrobial activity.
Sample Requirement:
Test substance solution 10 mL
Sample Count:
Accepts exactly 1 sample.
Detection of Escherichia coli
This method is applicable to all non-sterile cosmetic products. It is designed to detect viable Escherichia coli by ensuring that any antimicrobial properties of the cosmetic matrix (such as preservatives or whitening actives) are effectively neutralized.
Sample Requirement:
10 grams
Sample Count:
Accepts exactly 1 sample.
