Microbiological examination
Any cosmetic applied to the skin should not only be effective, but above all safe. Microbiological testing of cosmetics make it possible to assess whether a product is free of dangerous micro-organisms and whether the preservatives used effectively protect it from contamination. The MPR LABS laboratory carries out a wide range of analyses to ensure that quality and safety standards are met.
What does microbiological testing of cosmetics cover?
Microbiological tests is an important step in the quality control of cosmetics. This process involves several important tests:
- Microbiological purity test - assesses the presence of bacteria, moulds and yeasts in the product to exclude the risk of skin contamination.
- Maintenance test (Challenge Test) - checks the effectiveness of the preservative system and its ability to protect the product from contamination.
- Microbiological effectiveness studies - make it possible to determine how the cosmetic ingredients affect micro-organisms and whether they favour their growth.
- Research on the impact of cosmetics on the human microbiome - assess whether the product interferes with the skin's natural microflora, which is crucial for skin health and immunity.
Through these analyses, manufacturers can be sure that their cosmetics meet stringent hygiene standards and remain safe for users throughout their use.
Microbiology in cosmetology - how does it affect product safety?
Microbiology in cosmetology plays a fundamental role in assessing the quality of cosmetic products. Products containing water or natural ingredients are particularly vulnerable to microbial growth. Without adequate protection, they can become an environment conducive to the proliferation of bacteria and moulds, leading to the risk of skin irritation, infection and faster spoilage of cosmetics.
Regular microbiological examination allows the detection of possible hazards and ensures the appropriate shelf life of products. Microbiological testing is also essential at the formulation stage and also as part of the batch control of finished cosmetics.
For a cosmetic to be fully safe, it is not only necessary to microbiological examinationbut also physico-chemical tests. Physicochemical tests include analysis of pH, density, viscosity or water activity - all of which can affect a product's susceptibility to microbial growth. Therefore, a comprehensive analysis includes both types of tests, allowing a precise assessment of the stability and safety of cosmetics.
When should microbiological tests be carried out?
Microbiological testing of cosmetics should be carried out at various stages of the product life cycle:
- During the development of the new formula - to assess the microbiological stability and effectiveness of the preservatives,
- Pre-market - to meet regulatory requirements,
- During mass production - to ensure that each batch meets hygiene standards,
- During shelf life testing - to determine the shelf life of a cosmetic.
Our laboratory provides precision testing to help manufacturers meet regulatory requirements and ensure the highest quality of their products.

Microbiological tests of cosmetics are among the basic and most important analyses that must be performed before a cosmetic product is released on the market. They increase the safety of use of the product by consumers, enabling the detection of microorganisms considered dangerous in cosmetic samples. These can cause serious infections of the skin and mucous membranes.
The most popular microbiological tests of cosmetics include:
What is the importance of microbiological purity in cosmetics?
The microbiological purity of cosmetics is crucial to prevent contamination of products with micro-organisms that can cause skin infections or irritation. Therefore, cosmetics must be properly tested for the presence of bacteria, fungi and other pathogens.
What does water activity mean in a cosmetic?
Water activity in a cosmetic product refers to the amount of water available to support the growth of micro-organisms. Cosmetic products with higher water activity require a more effective preservative system to prevent the growth of bacteria or fungi.
What does EN ISO 21149 refer to?
EN ISO 21149 is a standard that specifies methods for the microbiological testing of cosmetics. Among other things, it defines methods for assessing the preservative efficacy and microbiological stability of cosmetic products.
What is the relevance of EN ISO 22718 for the cosmetics industry?
EN ISO 22718 is concerned with microbiological testing methods for cosmetics, including requirements for the quality of water used in the manufacture of cosmetics to ensure their safety and efficacy.
What does EN ISO 22717 describe?
EN ISO 22717 regulates methodologies and requirements for testing the microbiological properties of water used in the manufacture of cosmetics, as well as methods for analysing them for safety.
What does EN ISO 18416 cover?
EN ISO 18416 deals with the performance evaluation of cosmetics, particularly in the context of testing their effects on the skin and other body surfaces, as well as checking for potential allergic reactions.
What is the role of EN ISO 21150 in cosmetics production?
EN ISO 21150 focuses on procedures for quality control of cosmetics and methods of storage and transport to maintain their safety and efficacy throughout their shelf life.
What does EN ISO 16212 refer to?
EN ISO 16212 deals with methods for assessing and controlling the quality of cosmetics during their production, with an emphasis on the quality of ingredients and their compliance with safety standards.
What is the role of EN ISO 17516:2014 in cosmetics?
EN ISO 17516:2014 deals with methods for testing the efficacy and safety of cosmetics, especially in the context of their microbiological stability and quality control.
What does EN ISO 21148 specify?
EN ISO 21148 refers to procedures for testing cosmetics in the context of their microbiological quality and for controlling the presence of pathogens in products that may affect consumer health.
What does the study of the skin microbiome include in the context of cosmetics?
Skin microbiome testing involves analysing the microorganisms present on the surface of the skin to assess how cosmetics affect the natural bacterial flora. This research helps to develop products that support a healthy microbiome and protect the skin.
What is a biofilm and how does it affect cosmetics?
A biofilm is a structure formed by micro-organisms that adhere to a surface to form a protective layer. In the context of cosmetics, biofilm can affect their stability and microbiological purity, so cosmetic products must be tested to prevent its development.
