Abstract
The present invention relates to a surface-modified nanoscale zinc oxide, where the surface modification involves coating with an oligo- or polyethylene glycol acid. This surface-modified zinc oxide is characterized in that it forms stable dispersions in a liquid medium. In addition, the present invention relates to a process for the production of surface-modified zinc oxide, and also to a process for the production of nanoscale zinc oxide dispersions.
