Comprehensive analyses for successful toxicological examination

 Analytics on nanomaterials in cosmetics

Additionally, we provide a wide range of physico-chemical and microbiological analysis services for cosmetics.

Our physico-chemical analyses are conducted to determine the composition and properties of cosmetic products:

  • Physical indicators: pH, viscosity, density
  • Allergen content determination
  • Heavy metals quantification
  • Preservative content determination
  • Formaldehyde analysis
  • Oxidation stability

Our microbiological analyses, on the other hand, are performed to assess the presence of pathogenic or undesirable microorganisms in cosmetic products. We utilize advanced techniques for these analyses:

  • Analysis of mesophilic aerobic bacteria
  • Yeast and mold detection
  • Identification of pathogenic germs such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, and other microorganisms
  • Microorganism identification
  • Evaluation of the preservative system through challenge tests in accordance with ISO 11930
  • Salmonella detection
  • Measurement of water activity (aw test)
  • Microbiological control of process or production water
  • Microbiological controls of raw materials

Our microbiological laboratory is accredited by COFRAC*, providing you with a legally recognized authority throughout Europe.

Our analyses are conducted in our state-of-the-art laboratory, using standardized analysis methods and rigorous quality protocols to ensure reliable and precise results.
