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.

Abstract: Disclosed is a fluid cosmetic composition comprising a sebum-absorbing calcium silicate. These cosmetic compositions provide effective, long-lasting facial cosmetic coverage that is highly resistant to the sebum-caused deterioration that results in the discoloration and fading typically experienced by conventional cosmetic compositions after a sustained period of use. The cosmetic composition may be in the form of a créme, lotion, gel, semi-solid, dispersion, suspension, foam, mousse or spray.

Abstract: Disclosed is an oral care composition comprising a calcium metasilicate having an aspect ratio (average major axial diameter/average minor axial diameter) of from about 1:1 to about 2.5:, and an oil absorption of from about 20 ml/100 g to about 220 ml/100 g. Also disclosed is an oral care composition comprising: a calcium metasilicate having an aspect ratio (average major axial diameter/average minor axial diameter) of from about 1:1 to about 2.5:, and an oil absorption of from about 20 ml/100 g to about 220 ml/100 g, a disintegration aid, an organoleptic enhancing agent, and an abrasive.

Abstract: An improved method for slurrying bulk dry powder material within a hopper car is described. The method includes providing a static web of individual strands extending through the interior of the hopper compartment so that when water is admitted to the bottom of the hopper car, the water will travel upwardly along the strands of the web and through the dry bulk material to wet the same.
