ISO 21149: Enumeration of Aerobic Mesophilic Bacteria in Cosmetics

Cosmetics - Microbiology - Counting and detection of aerobic mesophilic bacteria

ISO 21149

ISO 21149 is a test standard for determining the count of aerobic mesophilic bacteriain cosmetic and personal care products. This test plays an important role in ensuring the microbiological safety of cosmetic products. Aerobic mesophilic bacteria are bacteria that can generally multiply in the temperature range of 20-45°C and survive in the presence of oxygen. These microorganisms can increase the risk of contamination of products and jeopardize user health.

The main purpose of microbiological analyzes in cosmetic products is to detect changes that may occur during the shelf life and open packaging process. Within the scope of microbiological analyzes in cosmetic products, the microorganisms that should be sought in cosmetic products in the “Guidelines for the Analysis of Cosmetic Products” are as follows:

• Aerobic Mesophilic Bacteria
• Staphylococcus aureus
• Yeast and mold
• Escherichia coli
• Candida albicans
• Pseudomonas aeruginosa

What are Aerobic Mesophilic Bacteria?

Aerobic mesophilic bacteria are species of bacteria that survive in oxygenated environments and usually multiply at moderate temperatures. Mesophilic means that these species grow best between 20°C and 45°C. These bacteria can be found in natural environments such as the skin, nose and mouth, but also in cosmetic products. Such bacteria in cosmetic products can lead to product contamination and health risks. Therefore, the safety of products must be ensured and such microorganisms must be counted.

Importance of ISO 21149 Testing

1. Health Safety: Aerobic mesophilic bacteria can cause infections in cosmetic products. These bacteria pose potential hazards that can lead to irritation of the skin, eyes and mucous membranes. ISO 21149 is used to detect these risks.
2. Product Quality: Microbiological testing is necessary to improve the quality of cosmetic products and ensure user safety. These tests ensure that products are checked regularly and prevent poor quality products from being placed on the market.
3. Legal Compliance: Most countries have specific regulations to ensure the microbiological safety of cosmetic products. ISO 21149 is required to comply with these regulations and may be legally mandatory.
4. Production Control: This test helps you detect any microbial contamination in the early stages of the production process. In this way, necessary improvements can be made to the production process.
