John P McDermott is a notable inventor based in Wheeling, IL (US). He has made significant contributions to the field of polishing compositions, particularly with his innovative patent that enhances the effectiveness of polishing agents.
Latest Patents
John P McDermott holds a patent for an abrasive polishing composition. This composition includes abrasive particles suspended in a carrier vehicle that consists of an organic liquid, such as glycerine, along with a mixture of gelling agents, including edible gum and seaweed extract. The formulation is designed to create a viscous semi-gel or sol, which improves its adherence to rotary applicators and work surfaces during polishing. The preferred mixture of gelling agents, gum tragacanth and agar, enhances the physical properties of the carrier vehicle. The composition typically contains over 85 percent by weight of glycerine and less than 10 percent by weight of water, exhibiting Newtonian flow characteristics and resisting melting at elevated temperatures. Additionally, the patent outlines a method for using this composition in a multi-step polishing process, which reduces abrasive particle size in each step to achieve a smooth, mirror-like finish, particularly beneficial for restorative tooth materials.
