METHOD FOR PREPARING SURFACE-MODIFIED, NANOPARTICULATE METALOXIDES, METAL HYDROXIDES AND/OR METAL OXYHYDROXIDES

摘要

Powdery preparations of surface-modified, nanoparticulate particles of at least one metal oxide, metal hydroxide and/or metal oxyhydroxide are disclosed, as well as a method for preparing the same and their use for cosmetic sunscreen preparations, as stabilisers in plastics and as active antimicrobial substances. Also disclosed is a method for producing aqueous suspensions of surface-modified, nanoparticulate particles of at least one metal oxide, metal hydroxide and/or metal oxyhydroxide.
