Abstract: Unique abrasive and/or thickening materials that are in situ generated compositions of precipitated silicas and silica gels are provided. 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/100 g 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.

Abstract: A gel/precipitate silica composite for use in a dentifrice composition has a maximum light transmission of at least 25% within a refractive index range of from about 1.432 to about 1.455; a relative flavor availability as compared to silica sand of at least 50%; a CTAB of less than about 40; and, when incorporated into a dentifrice composition in an amount of 20% by weight, said dentifrice has a RDA (Relative Dentin Abrasion) value of at most 130; a PCR (Pellicle Cleaning Ratio):RDA ratio of from 0.7 to 1.3; and a haze value after 24 hours of less than about 50%.

Abstract: Unique dentifrices comprising unique abrasive biogenic silica materials are provided. Such compositions exhibit excellent abrasive characteristics, either alone, or in combination with other types of abrasives. In such combinations (with precipitated silica materials, as one example), 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, even at low levels of such biogenic silica additives. Such biogenic silica particles thus surprisingly accord beneficial properties within dentifrice compositions. Encompassed within this invention is the method of utilizing such biogenic silica products within dentifrices, either as the majority abrasive component, or in combination with any other type of commonly used abrasive material.

Abstract: The treatment of cooking oils and fats with specific types of calcium silicate-based materials to prolong the useful life of such oils and fats within restaurant settings is provided. More particularly, such an invention encompasses the utilization of calcium-based aluminosilicate materials to filter such oils and/or fats or the incorporation of calcium silicate with or within previously utilized cooking oil filter materials (such as magnesium silicate) for the same purpose. Such calcium silicate-based materials and treatments therewith aid to remove greater amounts of free fatty acids after such oils and/or fats have been utilized to fry foodstuffs, as well as reduce the amount of additional oil and/or fat potentially necessary to bring the used oils and/or fats up to a level of permitted further utilization within a restaurant environment.
