Microbiology Testing for Cosmetics
Expert microbiology cosmetics testing services which help you to reduce microbiological risks, meet regulatory requirements and ensure the quality and safety of your toiletries, beauty and personal care products
Microbiological testing is a key aspect of cosmetic product safety and quality. In order to meet the regulatory requirements, such as those specified by the Cosmetics Regulation (EC) 1223/2009, the microbiological quality of raw materials must be well understood and furthermore, batches of formulated cosmetic products must be tested for microbiological quality before released.
Our centres of excellence for cosmetics microbiology testing in the US and Europe provide expertise that can support you from product include preservative efficacy testing (also known as challenge testing), quality control testing and research and development support, helping our clients to ensure product quality and safety.
Preservative Efficacy Testing
We conduct challenge testing of cosmetics preservative systems to help you to evaluate the antimicrobial protection of a cosmetic product during the product shelf-life according to relevant international standards including the International Standard ISO 11930, European Pharmacopoeia (EP) Chapters 5.1.3, French Standard NF T 75-611 and the United States Pharmacopeia (USP) Chapter <51> Antimicrobial Effectiveness Testing. Microorganisms typically used for challenge testing include Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Aspergillus brasiliensis however other microorganisms can be added if required.
Total Viable Count Tests
To determine the microbiological specification of the finished cosmetic product, measurement of the total count of aerobic mesophilic microorganisms as well as yeasts and fungi is required with comparison against industry established allowable limits. Our microbiology teams deliver robust testing services to help you understand the microbiological cleanliness of your products and support the release of your batches in accordance with the standards ISO 16212 (Enumeration of yeast and mould), ISO 21149 (Enumeration and detection of aerobic mesophilic bacteria).
