Patent number: 7306788Abstract: 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.Type: GrantFiled: November 24, 2004Date of Patent: December 11, 2007Assignee: J.M. Huber CorporationInventors: Patrick D. McGill, William C. Fultz

Patent number: 7303766Abstract: Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well.Type: GrantFiled: February 3, 2005Date of Patent: December 4, 2007Assignee: J.M. Huber CorporationInventors: Michael C. Withiam, Donald P. Conley, Michael Simone

Patent number: 7297318Abstract: Methods for the removal of lead from a metal silicate during the process of manufacturing of such a material are provided. With the reliance upon lower cost starting silicon dioxide starting materials that are known to exhibit elevated amounts of heavy metal therein for the purpose of producing metal silicates (such as sodium silicate, as one example), it has been realized that removal of significant amounts of such heavy metals is necessary to comply with certain regulatory requirements in order to provide a finished material that exhibits the same low level of heavy metal contamination as compared with finished materials that are made from more expensive, purer starting silicon dioxides. Two general methods may be followed for such decontamination purposes. One entails the introduction of a calcium phosphate material, such as dicalcium phosphate, tricalcium phosphate, and/or hydroxyapatite, to a formed metal silicate solution but prior to filtering.Type: GrantFiled: November 17, 2005Date of Patent: November 20, 2007Assignee: J.M. Huber CorporationInventors: Yung-Hui Huang, John V. Offidani

Patent number: 7273521Abstract: A new and useful method of simultaneously producing and granulating composite materials for simultaneous internal delivery of high amounts of calcium and phosphate to a subject (person or animal) is provided. Such a method entails the dropwise addition of concentrated phosphoric acid within a specified amount of water into a vessel containing a powdered material of lime and/or calcium carbonate, with the lime and/or calcium carbonate present in an excessive amount of the phosphoric acid, with subsequent, mixing, drying, milling, and sieving to provide the correct target particle size range for the resultant granulated materials. Such specifically produced granulated calcium carbonate/dicalcium phosphate materials exhibit very high available calcium levels, very high available phosphate levels, excellent flow characteristics, and very high capability for compression into tablets.

Patent number: 7270803Abstract: Unique abrasive materials that are in situ generated compositions of precipitated silicas and silica gels are provided. Such compositions exhibit different beneficial, particularly simultaneously high pellicle film cleaning properties and moderate dentin abrasion levels. Such a result thus accords the user a dentifrice that effectively cleans tooth surfaces without detrimentally abrading such surfaces.

Patent number: 7262233Abstract: Disclosed is a silica substrate treated with a polysiloxane, and an organosilane, wherein the organosilane is described by the formula: RSi(R?)x(OR?)3-x; wherein R is a long-chain hydrocarbon group having between about 8 to about 30 carbon atoms, which may also contain organofunctional groups such as vinyl, methacryl, amino, sulfur, and epoxy groups; R? and R? are independently selected from a methyl and ethyl group; and X is either 0 or 1. The optimal use for the treated silica substrate is as a rheology modifier in epoxy polymer materials, however, the silica substrate could also be used in other chemical compositions such as polyurethanes, polyesters, silicones, and hydrocarbon oils.Type: GrantFiled: December 28, 2004Date of Patent: August 28, 2007Assignee: J.M.

Patent number: 7255852Abstract: Precipitated silica comprising porous silica particles having a cumulative surface area for all pores having diameters greater than 500 ? of less than 8 m2/g, as measured by mercury intrusion, and a percentage cetylpyridinium chloride (% CPC) Compatibility of greater than about 55%. The precipitated silica product is especially well-adapted for use in dentifrices containing cetylpyridinium chloride, which do not attach to the low surface area silica product in a meaningful level and thus remain available for antimicrobial action. Processes for making the silica product are also provided.Type: GrantFiled: October 3, 2003Date of Patent: August 14, 2007Assignee: J.M. Huber CorporationInventors: Karl W. Gallis, Mark E.

Patent number: 7172651Abstract: Pigment suitable for use in coating compositions for inkjet recording media. Surfaces of an inorganic particulate are interacted with a water-soluble polyvalent metal salt in an aqueous medium. The treated particle surfaces have a significant cationic surface charge imparted to them. The salt is a salt of a metal of Group II or Group III of the Periodic Table. Inkjet recording media treated with a coating composition containing the above pigment provide high density, fast-drying, and non-feathering ink images with suitable water fastness, while the coating compositions also offer cost advantages and improved rheology at higher pigment levels over coatings based on silica pigments.Type: GrantFiled: June 17, 2003Date of Patent: February 6, 2007Assignee: J.M.
