Beer Stabilization (continued) NALCO Nalco 1072 – ( Kieselsol or SilicaSol ) 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 (through filtration) from the stabilized beer. Nalco 1072 is a ready-to-use solution that offers convenience in use.

• For Nalco application in high & low gravity brews, all dosages are effective in lowering the NTU and achieving a clean sample in comparison to the control. • There is a correlation between product efficiency and contact time. A lower dosage can be used to achieve target clarity over a longer period of time (1-24hrs.). On the same note, a higher dosage can be used to achieve target clarity over a shorter period of time (1-24 hrs). • For commercial application, it is recommended to do dosage optimization trials to determine an ideal dose and contact time.
