Genotoxicity testing of a poorly soluble polymer: overcoming matrix complexity (UVCB)

Context:

A client approached GenEvolutioN for a genotoxicity assessment of a polymer ingredient classified as a UVCB (Unknown or Variable composition, Complex reaction products or Biological materials). Due to its extremely low solubility, standard genotoxicity test protocols presented significant technical challenges.

Action of GenEvolutioN

Leveraging our expertise in in vitro toxicology and advanced protocol customization, GenEvolutioN adapted its testing strategies to address the unique properties of this complex matrix. Our laboratory optimized the sample preparation and analytical conditions, ensuring reliable exposure and accurate results even with limited solubility.

Results:

The genotoxicity analyses conclusively demonstrated that the polymer component was not mutagenic. This not only met the client’s regulatory and safety requirements, but also highlighted GenEvolutioN’s ability to deliver robust genotoxicity data for complex UVCB substances. Our adaptive approach reinforces our reputation as a partner of choice for challenging genotoxicity testing scenarios in cosmetics, pharma, and chemical industries.
