NANOPARTICULES POLYMERISEES EN RESEAU ACTIF OU BIOACTIF, TOPIQUES PROTECTEURS, LEURS PROCEDES DE PREPARATION ET LEUR UTILISATIONS

摘要

The invention concerns a compound formed by functionalised micro- or nanoparticles covalently associated with rheology-modifying polymers. The invention is characterised in that the functionalised micro- or nanoparticles are functionalised inorganic or metal oxide micro- or nanoparticles, in particular aluminium oxide (Al2O3), copper oxide (CuO), iron oxide (Fe3O4 or γ-Fe2O3), magnesium oxide (MgO), silica (SiO2), titanium dioxide (TiO2) or zinc oxide (ZnO), having a nominal diameter of between 1 and 1500 nm; and in that the rheology-modifying or -adapting polymers are chosen from non-associative polymers or associative polymers. The invention applies to protection or decontamination of the skin.
