ABSTRACT:
The present invention describes a process for preparing a surfactant-free suspension including hydrophobic particles and at least 50.01% by weight of water, where hydrophobic, nanostructured particles are suspended in at least one organic solvent miscible with water and having a boiling point below 150° C., and then this concentrated organic suspension is intensively and thoroughly mixed with surfactant-free water.
