[...] Therefore, our analysis highlights a strong implication of the use of nanoparticles in the manufacture of L'Oréal group cosmetics, on numerous planetary limits. In fact, despite the commitments made by the company in favor of greater transparency and environmental and health protection, our evaluation highlights many impacts of these uses, highlighting problems, both at the social, political, and environmental levels. While the OECD shows that these particles are not treated by incineration plants or purification zones, the study of the evolution of these materials in the environment is still in its infancy and the work on improving their biodegradation must still be carried out to its conclusion according to the European Biochemicals Agency.

[...] The damage to neurogenic cells would thus be all the more important as « neurons regenerate very little, increasing their vulnerability in case of injury » Bencsik, 2015). In addition, the impact of nanoparticle exploitation on the environment, particularly on the «cycle of coral development and its symbiotic algae » with particular effects on « the mortality of corals», « the reproductive cycles of certain species of fish » linked to the release of nanoparticles from sunscreens in aquatic environments, translates a strongly deleterious effect on the environment Quédraogo, 2022). [...]
[...] Therefore, understanding and analyzing, precisely, the scope of these new materials on health and the environment seems today to be crucial, in order to better grasp the group's involvement in its promise of social and environmental progress. Also, the use of the 'donut' economic model defined, according to Kate Raworth, former researcher within a British NGO, around seven key principles, intended to ensure social justice, through internal social and environmental benefits, that is to say intended for humans, should allow us to obtain a systemic approach to the question, but also to examine and characterize, in an organized way, the entire set of these challenges.
