    Abstract: The present invention provides a method of reducing chill haze in a protein containing liquid (especially beverages resulting from fermentation such as beer and wine) by contacting the liquid with silica microgels having an average microgel diameter of at least 18 nm, more preferably at least 45 nm, and most preferably at least 70 nm. It has now been discovered that microgels having an average microgel diameter of less than about 18 nm do not adequately reduce chill haze of a protein containing liquid. In particular, while microgels having an average microgel diameter of less than about 18 nm cause the coagulation of haze-forming components, these components remain suspended in liquid and continue to cause haze despite allowing the liquid to settle for long periods of time. Conversely, it has now been discovered that microgels having an average microgel diameter of at least about 18 nm cause the coagulation and precipitation of haze-forming components and the rapid settling thereof without the use of an organic polymer which acts as a flocculating agent.

    Abstract: This invention relates to unique abrasive and/or thickening materials that are in situ generated compositions of precipitated silicas and silica gels. Such compositions exhibit different beneficial characteristics depending on the structure of the composite in situ generated material. With low structured composites (as measured via linseed oil absorption levels from 40 to 100 ml oil absorbed/ 1OOg composite), simultaneously high pellicle film cleaning properties and moderate dentin abrasion levels are possible in order to accord the user a dentifrice that effectively cleans tooth surfaces without detrimentally abrading such surfaces. Increased amounts of high structure composite materials tend to accord greater viscosity build and thickening benefits together with such desirable abrasion and cleaning properties, albeit to a lesser extent than for the low structure types. Thus, mid-range cleaning materials will exhibit oil absorption levels from an excess of 100 to 150, and high thickening/low abrasion composite exhibit oil absorption properties in excess of 150. Such an in situ,simultaneously produced precipitated silica/silica gel combination provides such unexpectedly effective low abrasion and high cleaning capability and different thickening characteristics as compared to physical mixtures of such components. Encompassed within this invention is a unique method for making such gel/precipitated silica composite materials for such a purpose, as well as the different materials within the structure ranges described above and dentifrices comprising such.
