Nalco 1072 kieselsol is a liquid colloidal suspension of silicon dioxide, which is extremely effective in chillproofing and has been used in production of “vegan-friendly” beers. The resulting silica/protein complexes form relatively compact sediment cakes (tank bottoms) that aid in separation from the stabilized beer. Nalco 1072 is a ready-to-use solution that offers convenience in use.
