SURFACE-MODIFIED ZINC OXIDES

摘要

Surface-modified zinc oxides with a BET surface area of 18 ± 5 m^2/g and a C content of 0.1 to 5.0 wt.% are prepared by spraying the zinc oxides with the surface-modifying agent or adding this in vapour form and then heat-treating the mixture. They can be employed for the preparation of cosmetics.
