Detection of Pseudomonas aeruginosa in Cosmetics

The ISO 22717 standard covers test and analysis methods for the detection and identification of Pseudomonas aeruginosa in cosmetic products. Pseudomonas aeruginosa is commonly found in soil and water. Pseudomonas aeruginosa is the most common infectious species among many different Pseudomonas species.

The first step of the ISO 22717 standard procedure is to perform an enrichment using a non-selective medium to increase the number of microorganisms without the risk of inhibition by selective components present in the selective/differential growth medium. The second step of testing (isolation) is performed on a selective medium, followed by identification tests.

Producing cosmetic products in unhygienic environments or microorganism growth and proliferation may occur after the package is opened. Pseudomonas aeruginosa Detection should be performed to determine cosmetic product quality and shelf life.
