Taiwan's Guidelines for Microbiological Testing of Cosmetic Products (RA03M001.004)

Taiwan's Food and Drug Administration (FDA), dated February 19, 2025, outlines the microbiological testing methods for cosmetics, specifically focusing on testing the aerobic plate count (bacterial count) in cosmetic products. The method involves diluting the sample and culturing it on an appropriate growth medium to measure the bacteria present. The document specifies the necessary conditions, including the equipment, materials, and environmental standards required for testing. It details specific safety and testing protocols, including the use of sterilized tools, biological safety cabinets, and temperature-controlled incubation. Furthermore, it provides formulations for various growth media, including Modified Letheen broth and MacConkey agar. These tests ensure the microbiological safety of cosmetics.
