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. The complexity of the substance to characterize required specific expertise in ecotoxicology and a customized study protocol.
Key words
Linked expertise
Ecotoxicity and biodegradation specialists from Capacités were selected for their Expertise on non-ready biodegradable chemicals. The client asked them to study the ecotoxic properties of a new polymer.
The experts physiochemically characterized the polymer to determine the operating conditions to conduct optimized ecotoxicological trials. For this, they studied its composition as well as solubilization and volatilization properties.
Following this pre-study, they measured the polymer’s toxicity and biodegradability in the two environments where the polymer is released at its end of life: seawater and activated sludge. They gained understanding both on its ready and inherent biodegradation properties during this study. The byproducts released by its partial biodegradation erase were also analyzed for safety.
To successfully complete this project, the Capacités’ experts benefited from support and technical equipment from the GEPEA, joint research unit of Université de Nantes, Oniris, IMT Atlantique and CNRS (The French National Centre for Scientific Research).

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.
GLS is an engineering company specialised in water treatment and, as such, frequently designs wastewater treatment plants. In that context, it must comply with the legal limits of nitrogen and phosphorous content in the treated wastewater discharged from the plant.
