Nanoparticles: First European laboratory accredited
Considered as potentially hazardous to human health, nanomaterials are used in several sectors such as construction, food, and cosmetics. International regulations apply pertaining to the use of nanomaterials, including European regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals, and Californian regulations.
To ensure your cosmetic products comply with regulatory obligations, Eurofins companies offer dedicated tests to characterise and analyse nanoparticles, including titanium dioxide TiO2 and zinc oxide ZnO.
Our specialised laboratory in France is the first European laboratory accredited in accordance with the NF EN ISO/IEC 17025 standard on the characterisation of the morphology and distribution size for nanoparticles in raw materials used in cosmetics and finished cosmetics products using Transmission Electron Microscopy (TEM) technology.

An ex vivo human skin model to design microbiome-friendly products
Our skin is home to a very large number of microorganisms, which can be classified as commensal, symbiotic, or pathogenic, depending on their "link" with the host.
The term "skin microbiota" covers all the microorganisms present on the skin. Numerous studies have highlighted the role of skin microbiota in the quality of skin tissue. Therefore, it is important to maintain a healthy skin microbiome.
Certain cosmetic products may contain ingredients that can impact the composition of the skin's microbiota and induce lasting changes.
That’s why our experts designed an ex vivo human skin model with three different bacterial strains, such as S. epidermidis, S. aureus, C. acnes and Corynebacterium spp.
Using microbiology techniques, the human skin model makes it possible to determine the impact of various cosmetic products on the growth or formation of bacterial biofilms on the skin!
This allows for the validation of cosmetic product claims such as:
- microbiote-friendly, pre-pro-biotic
- anti-microbial activity: demonstrate that a product inhibits the growth of pathogenic bacteria while preserving commensal bacteria.
- demonstrate the ability of a product to stimulate antimicrobial peptides
- anti-dandruff activity thanks to the model where explants from the scalp are inoculated with three different strains of Malassezia.
This ex vivo approach complements Eurofins’ complete microbiota offering (including clinical evaluation, instrumental analysis, and metagenomic analysis).
Substantiate your cosmetic product claims with our innovative image analysis software
Image analysis is becoming increasingly popular in the cosmetics sector to analyse skin health (with the ability to highlight hyperpigmentation, uneven skin tone and similar issues) and to illustrate the effectiveness of skincare products, thanks to detailed imaging.
With years of experience in image analysis, the Eurofins Cosmetics & Personal Care network supports cosmetic companies with image processing and analysis to validate cosmetic product claims.
