In vitro toxicity tests are an important tool in evaluating the safety and tolerability of cosmetics and personal care products. Mérieux NutriSciences offers proven practical experience in the application of GLP-compliant, validated* biochemical and in vitro toxicology testing methods.

We combine different in vitro methods as part of an integrated testing strategy (ITS) for safety evaluation. This enables us to get closer to the overall goal of predictive in vitro risk evaluation processes to eliminate or reduce the use of animal testing.


Mérieux NutriSciences offers a wide range of ITS in vitro validated assays using cell models and 3D human reconstructed tissues for the evaluation of:

  • Skin irritation and corrosion
  • Eye irritation
  • Skin sensitization
  • Phototoxicity
  • Cytotoxicity
  • Mutagenicity
