The instant invention relates to a process for the preparation of an
aqueous suspension of anionic colloidal silica having a neutral pH which
is stable over time and comprises individualized particles of colloidal
silica which are not bound to one another by siloxane bonds. The instant
suspensions show high storage stability and are particularly useful for
the clarification of beer, for the preparation of cosmetic formulations,
for the production of ink for printers, for paints and for anticorrosive
treatments.
