  • Polymerised cerium oxide nanoparticles in an active or bioactive network, protective topical treatments, methods for preparation thereof and uses thereof
    Patent number: 10155869
    Abstract: The invention concerns a compound formed by functionalized micro- or nanoparticles associated covalently with rheology-modifying polymers. The invention is characterized in that the functionalized micro- or nanoparticles are functionalized micro- or nanoparticles of cerium oxide (CeO2) having a nominal diameter of between 1 and 1500 nm. The rheology-adapting or -modifying polymers are selected from among non-associative or associative polymers. The invention is used in skin protection or decontamination.
