Microbiological inspections of cosmetic products are carried out strictly in every country. Each country tries to comply with national and international methods, criteria and standards developed during audits. For example, in the United States, a number of guidelines have been developed by the Cosmetic Manufacturers Association (CTFA) and microbiological quality requirements for cosmetic products have been established. All manufacturers operating in this country must comply with these requirements.

In our country, the Ministry of Health has issued a Guide on Cosmetic Law, Cosmetic Regulation and Microbiological Control of Cosmetic Products. These regulations are based mainly on the American cosmetic practices mentioned above and are dangerous to human health in cosmetic products, and are dangerous for Escherichia Coli, Pseudomonas Aeruginosa, Salmonella Typhimurium, Candida Albicans, Aspergillus Niger and Staphylococcus Aureus bacteria in the cosmetic products in any way is required.

Today, Pseudomonas Aeruginosa is one of the most important bacteria in nosocomial infections. This bacterium is naturally resistant to many antibiotics and has mutated and become resistant to all treatments.

Pseudomonas Aeruginosa bacteria are usually found in water. Pseudomonas Aeruginosa, a type of bacterium that breaks down glucose by oxidation, can also spread very quickly in water-based cosmetic products and cause various discomforts in users.

In these studies conducted by accredited laboratories, the following standards are taken into consideration:

• TS EN ISO / IEC 17025 General Conditions for the Qualification of Test and Calibration Laboratories
• TS EN ISO 22716 Cosmetics - Good Manufacturing Practices (GMP) - Guidance on Good Manufacturing Practices
• TS EN ISO 22717 Cosmetics - Microbiology - Pseudomonas aeruginosa

In addition, competent laboratories have a strong technological infrastructure and an experienced and well-trained staff in order to achieve quality, fast and reliable results.
