Microbiological Parameters And Standards Considered In Microbiological Test Analysis In Cosmetic Products
PARAMETERS AND STANDARDS CONSIDERED IN THE MICROBIOLOGICAL ANALYSIS OF COSMETIC PRODUCTS

The tests to be performed to check the microbiological suitability of cosmetic products are total aerobic mesophytic bacteria count and mold yeast count. Microorganisms that should definitely not be present in cosmetic products are Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Escherichia coli.

Microbiological risk analysis includes user type, application area, and possible changes in cosmetic products. Regarding microbiological quality analyses, according to the "GUIDE ON MICROBIOLOGICAL CONTROL OF COSMETIC PRODUCTS", two separate categories have been defined for cosmetic products since different skin areas may have different sensitivities.

Categories
Category 1: Products for children under 3 years of age, products applied to the eye area, products applied to mucous membranes, leave-in products
Category 2: Other products, rinsed products

Quantitative Limits:
Category 1: The total number of live aerobic mesophilic microorganisms (bacteria, yeast and mold) should not be more than 100 cfu/g or 100 cfu/ml.
Category 2: The total number of live aerobic mesophilic microorganisms should not be more than 1000 cfu/g or 1000 cfu/ml.

Qualitative/qualitative limits:
Category 1: Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans or Escherichia coli should not be present.
Category 2: Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans or Escherichia coli should not be present.

Total live aerobic mesophilic microorganism ISO 21149
Staphylococcus aureus ISO 22718
Pseudomonas aeruginosa ISO 22717
Escherichia coli ISO 21150
Candida albicans ISO 18416
Yeast and Mold ISO 16212
