Abstract: A family of novel and unique synthetic alkali metal alumino-silicates (SAMS) are produced by the hydrothermal reaction between kaolin and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 :zH.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is the alkali metal, y is the number of moles of SiO.sub.2 in the unique SAMS compositions and is an integer greater than 2.0, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO.sub.2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.

Abstract: Disclosed are thixotropic polyester compositions wherein the thixotropic characteristics are provided by incorporation into the polyester of a member selected from the group consisting of a precipitated silicon dioxide and a mixture of a precipitated silicon dioxide and a fumed silica. The resulting thixotropic polyester compositions are useful in industries where the resin must not drain from a vertical surface before cure, such as in the boat building industry, and in electrical and transportation applications, and particularly in fiberglass reinforced unsaturated polyester resins and gel coats.

Abstract: A method for producing a precipitated silicon dioxide having a new combination of physical and chemical properties is disclosed. The pigments are produced by acidulating a solution of an alkali metal silicate with an acid under controlled precipitation conditions. The aqueous reaction medium comprising the precipitated silica is then post-conditioned by introducing a second silicate solution into the reaction vessel and thereafter adding additional acid to react with the said second silicate solution. By varying the amount of the silicate employed in the post-conditioning step, a product is obtained which has a unique combination of physical and chemical properties including reduced wet cake moisture content, high surface areas and oil absorptions, improved surface activity, friability, wetting characteristics, and the like. The product has particular utility for use as a rubber reinforcing agent because of its increased surface activity and oil absorption, etc.

Abstract: Novel precipitated silicon dioxide abrasive compositions which can be incorporated into therapeutic toothpaste compositions containing both soluble fluoride salts and soluble phosphate salts are disclosed. The abrasives comprise low structure precipitated silicon dioxides which have been reacted with about 10 to 300 parts per million alkaline earth metal ion, particularly calcium. Reaction with the alkaline earth metal ion minimizes abrasive interaction with the fluoride ion source in therapeutic toothpaste. Also provided are methods for preparation of the novel silicon dioxide abrasives and resulting toothpaste formulations containing such abrasives.

Abstract: The corrosion and staining of unlined aluminum tube surfaces by dentifrices such as toothpastes, particularly when the dentifrices contain therapeutic agents, is substantially prevented by incorporation into the dentifrice of a controlled amount of an alkaline earth metal ion such as calcium ion, in the range of 0.005-0.2 weight percent, and preferably in the range of 0.005-0.070 weight percent of the dentifrice. The alkaline earth metal may be provided from any water soluble alkaline earth metal salt or as a reaction product of the alkaline earth metal salt with an amorphous silica abrasive and/or thickener.
