Patent number: 7731110Abstract: A method of making abrasive compositions, and more particularly, it relates to a method of making precipitated silica abrasive compositions having excellent cleaning performance and lower abrasiveness with post-reactor sizing of the abrasive particles being performed directly via wet comminution and centrifugation, optionally followed by hydraulic chamber press filtering combined with vacuum dewatering and de-agglomeration is provided. By targeting a specific particle size range, it has been determined that higher pellicle film cleaning levels may be achieved without also increasing the dentin abrasion properties of the silica products themselves. As a result, dentifrices including such classified abrasive silica products, exhibiting particularly desirable cleaning benefits, can be provided for improved tooth polishing, whitening, and the like, without deleteriously affecting the hard tooth surfaces.Type: GrantFiled: June 29, 2005Date of Patent: June 8, 2010Assignee: J.M.

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.

Patent number: 7125432Abstract: New methods of producing narrower particle size distribution precipitated silica and/or silicate materials are provided. Such a method permits a significant reduction in manufacturing costs through the utilization of more efficient drying/evaporation components, in essence, in one potentially preferred embodiment, production of such silica and/or silicate materials followed directly by a hydraulic chamber press filtering step combined with vacuum dewatering subsequently leading to the needed resultant particle comminution. The resultant precipitated silicas and/or silicates produced thereby exhibit greater density prior to comminution and thus greater propensity for more uniform milling than previously utilized and prevalent spray/flash drying apparatuses.Type: GrantFiled: July 23, 2004Date of Patent: October 24, 2006Assignee: J.M.

Patent number: 5466763Abstract: A process is disclosed for preparing a polysulfide-epoxy prepolymer and cured co-polymer using a heavy ends waste generated in chlorinated hydrocarbon production. The process comprises first distilling the heavy ends waste to form an enriched heavy ends waste with an ethylene dichloride content less than about 10% by weight. The enriched heavy ends waste is then reacted with an alkaline polysulfide within a temperature range of about 50.degree. C. to about 150.degree. C. to form a polysulfide polymer mixture. Next, between about 5 and about 300 parts of the polysulfide polymer mixture is co-reacted with a hundred parts by weight of an epoxy resin to form a polysulfide-epoxy prepolymer or a cured co-polymer if a curing agent is present.Type: GrantFiled: November 8, 1994Date of Patent: November 14, 1995Assignee: Formosa Plastics CorporationInventors: Chester C.
