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.

Organoleptic Evaluation of Deodorizing Efficacy (Acidic Model)
The method evaluates the efficacy of the test sample in suppressing the vaporization of Short-Chain Fatty Acids (SCFAs), specifically Isovaleric Acid, which acts as a chemical marker for human axillary (armpit) and foot malodor. f the sample contains alcohols (ethanol) or enzymes from fermentation, the isovaleric acid may chemically react during the 37°C incubation to form an ester (e.g., Ethyl Isovalerate), which typically has a pleasant, fruity aroma rather than a malodor.
