Our experts in biodegradability and ecotoxicity study the biodegradability of chemical substances for which easy biodegradability, OECD 301b, is not proven.
Assessing the environmental profile of UVCBs, RBT, and other complex chemicals is critical to meeting societal concerns and REACH requirements.
On a daily basis, we provide R&D services to evaluate the biodegradability of chemical substances. We also lead collaborative research projects to meet the ecotoxicity characterization needs.

To assess the biodegradability of polymers and other chemical substances using a rapid, miniaturized and easily reproducible screening tests on an industrial scale.
You want to measure the biodegradability of your substance? Our experts have developed an early screening test to measure the biodegradation of UVCB chemicals and respond appropriately to the REACH regulation (Regulation (EC) No 1907, 2006).

Our biodegradability experts carry out their engineering work directly in the research laboratories of the University of Nantes, in particular at the GEPEA. On a daily basis, they combine technical means and scientific discoveries to meet your R&D challenges.
The client concerned is a leading player in the specialty ingredients sector for health and beauty. In 2019, it reaffirmed its confidence in Capacités and the GEPEA laboratory by requesting that their teams assess a new polymer’s ecotoxicity.
L’Oréal called upon the experts at the GEPEA Laboratory and Capacités in order to assist in bridging this methodological gap. The resulting new process has served to assist L’Oréal in developing methods for evaluating the biodegradability of their products, thus allowing them to better adhere to the strict regulatory requirements.
