     <dcterms:abstract xml:lang="fr">Avec des propriétés physico-chimiques tout à fait remarquables, les nanomatériaux (NM) ont conquis différents secteurs d’activités, notamment celui des cosmétiques. Cependant, ces NM suscitent aujourd’hui de nombreuses interrogations vis-à-vis de leurs potentiels risques pour la santé humaine, ces incertitudes étant en partie liées à un manque de recul sur les effets à long terme. Par conséquent, cette thèse s’est appuyée sur le système de Cosmétovigilance, véritable outil de suivi de la tolérance d’un produit cosmétique mis sur le marché, et a étudié la corrélation entre la présence de NM dans les produits et les effets indésirables rapportés. Les résultats, bien que non représentatifs de la population générale, ont montré des différences de tolérance pour certains produits avec NM. Toutefois, l’ensemble des données recueillies n’a pas fait ressortir de profil de risque majeur des NM et les bénéfices pour le consommateur sont certains. Dans ce cadre, une étude à plus grande échelle serait intéressante afin de confronter l’ensemble des hypothèses obtenues ici à celles d’autres entreprises cosmétiques ou encore d’agences de santé, ajoutant ainsi de nouvelles pistes de recherches à ce travail préliminaire.</dcterms:abstract>
     <dcterms:abstract xml:lang="en">With remarkable physicochemical properties, nanomaterials (NM) have gained various sectors of activity for several years, including that of cosmetics. However, these substances raise many questions about their potential risks to human health today, these uncertainties being partly linked to a lack of objectivity on the long-term effects. Therefore, this thesis focused on the Cosmetovigilance system, a real tool for monitoring the tolerance of a cosmetic product put on the market, and studied the correlation between the presence of NM in products and reported adverse effects. The results, although not representative of the general population, showed tolerance differences for some products with NM. However, all of the Cosmetovigilance data collected did not reveal a major risk profile of NM and the benefits for the consumer are evident. In this context, a study on a larger scale would be interesting to compare all the hypotheses obtained here with those of other cosmetic companies or health agencies, thus adding new lines of research to this preliminary work.</dcterms:abstract>
