Abstract:
The present invention relates to methods for the production of surface-modified, nanoparticulate particles of at least one metal oxide, metal hydroxide and/or metal oxyhydroxide and of aqueous suspensions of said particles. The invention also relates to the surface-modified, nanoparticulate particles of at least one metal oxide, metal hydroxide and/or metal oxyhydroxide and to the aqueous suspensions of said particles which can be obtained by these methods and their use for cosmetic sunscreen preparations, as stabilisers in plastics and as active antimicrobial active substance.
Abstract:
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.
