Anaerobic bacteria are a type of bacteria that grows in anaerobic environments or in environments with very little oxygen. Anaerobic bacteria cause pus, bad odors, abscess formation and skin irritation. Bad effects are mostly seen on the skin. They can develop rapidly on the skin and cause infection.

Anaerobic bacteria derive their energy by breaking down organic nutrients and generally do not use oxygen. That's why they live and grow in places that don't take air.

Cosmetic products are non-sterile products and are always open to contamination of microorganisms. Cosmetic products, when analyzed microbiologically, are non-pathogenic microorganisms because they are not produced under aseptic conditions. It is important that these microorganisms are not higher than the limit values ​​described and show no pathogenic properties. Otherwise, cosmetic products containing pathogenic microorganisms threaten the health of the users. Consumers may have to deal with various diseases rather than flourishing. Such microorganisms also cause the product to deteriorate in a short time.

The harm of cosmetic products to the health of consumers varies depending on the number and variety of microorganisms that grow in them. Cosmetic products are very suitable for the growth of microorganisms because of the chemical substances they contain. In this respect, anaerobic bacteria counts performed by laboratories are important studies. Authorized laboratories carry out these analyzes among microbiological analysis studies.

These laboratories perform such analyzes accredited by national or international accreditation bodies. Accreditation procedures are carried out in accordance with TS EN ISO / IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories. Accredited laboratories also consider TS EN ISO 22716 Cosmetics - Good Manufacturing Practices (GMP) - Guidance Standard on Good Manufacturing Practices.

In addition, laboratories comply with TS EN ISO 21149 Cosmetics - Microbiology - Aerobic mesophilic bacteria detection and enumeration standard and other standards.
