Abstract
Silicas modified with groups of the general formula (I)RSiRO—  (I)where at least one of R or Ris a >Chydrocarbon radical are useful in preparing stable dispersions of basic substances, the silica permitting a decrease in the shear viscosity h for a storage time of 1 week at room temperature (25° C.) to not more than 50% of the initial viscosity value, the viscosity being measured by means of cone/plate geometry with a shearing gap of 105 μm and a shear rate of 0.5 sat 25° C.
