  • Patent number: 8308985
    Abstract: 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.
