Certified Reference Materials for cosmetic analyses

Biosisto offers reference materials that match the strains mentioned in these ISO standards for cosmetics. These reference materials are essential for quality control to ensure that microbiological testing methods function correctly and provide accurate results.

ISO 21149 Cosmetics — Microbiology — Enumeration and detection of aerobic mesophilic bacteria
This standard specifies a method for detecting and enumerating aerobic mesophilic bacteria in cosmetics, ensuring the bacterial load is within acceptable limits.

ISO 16212 Cosmetics — Microbiology — Enumeration of yeast and mould
This standard provides a method for enumerating yeasts and molds in cosmetic products, which is important for preventing spoilage and ensuring product stability.

ISO 18415 Cosmetics — Microbiology — Detection fo specified and non-specified miroorganisms
This standard outlines the procedures for detecting specific pathogenic microorganisms, including Pseudomonas aeruginosa, Staphylococcus aureus, and Candida albicans, potential contaminants in cosmetics.

ISO 22717 Cosmetics — Microbiology — Detection of Pseudomonas aeruginosa
This standard focuses on detecting Pseudomonas aeruginosa, a bacterium that can cause infections, particularly in immunocompromised individuals.

ISO 22718 Cosmetics — Microbiology — Detection of Staphylococcus aureus
This standard specifies a method for detecting Staphylococcus aureus, a common skin pathogen that can cause various skin infections.

ISO 18416 Cosmetics — Microbiology — Detection of Candida albicans
This standard provides a method for detecting Candida albicans, a yeast that can cause infections, especially in individuals with compromised immune systems.

ISO 11930 Cosmetics — Microbiology – Evaluation of the antimicrobial protection of a cosmetic product
This standard is for evaluating the antimicrobial protection of a cosmetic product.
This standard is crucial for ensuring the safety and stability of cosmetic products by determining their ability to resist microbial contamination.

The purpose of this standard is:
– To assess the effectiveness of preservatives in cosmetic products.
– To ensure the microbial stability of products during their shelf life and usage.

This involves intentionally contaminating the cosmetic product with a known quantity of specific microorganisms and monitoring the product over time to see if the microbial population decreases to acceptable levels. Typically, bacteria and fungi, such as Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus brasiliensis, are used. The product must show a significant reduction in microbial count within a specified timeframe, indicating effective preservation.

Below is a list of suitable CRMs for cosmetic analysis.
