Patent number: 11445794Abstract: A method and kit for treating a nail surface. The method includes brushing or spraying an adhesive on a coated or uncoated nail surface to form an adhesive-coated surface. A covering (e.g., a curable nail gel, evaporative nail polish, or artificial nail) is then applied to the adhesive-coated surface. The covering is removable by soaking in solvent for less than 20 minutes, peeling, or a combination thereof.Type: GrantFiled: December 21, 2016Date of Patent: September 20, 2022Assignee: Mycone Dental Supply Company, Inc.Inventors: Stephen Crescimanno, Paul L.

Patent number: 8684739Abstract: Provided is a slow-release delivery vehicle for delivering at least one active ingredient into a film coating, comprising a population of stable, homogeneously-dispersed, porous polymeric or co-polymeric beads having a network of pores, wherein the at least one active ingredient is held within the bead particles and within the network of pores and slowly released by internal flow, and wherein the network of pores is substantially non-collapsible upon removal of the active ingredient. The porous co-polymer bead preparation comprises a continuous aqueous phase solution containing a monomeric mixture of at least one polyvinylaromatic monomer and at least one porogen forming a network that comprising (i) macropores; (ii) mesopores; (iii) micropores; and (iv) gel porosity. Also provided are methods of preparing the porous co-polymer bead preparation; and for its use as a slow-release delivery vehicle.Type: GrantFiled: March 14, 2003Date of Patent: April 1, 2014Assignee: Mycone Dental Supply Co., Inc.Inventors: Larry W. Steffier, David Kurz, Robert R. Raney, Cary B. Robinson

Patent number: 6051242Abstract: Quick drying coating compositions, preferably but not exclusively for application to natural or artificial nails are provided. The quick-drying coating composition comprises a base or lacquer component and an optional pigment component. The base component can dry in less than about 70 seconds under ambient conditions, yet is free of undesirable solvents and components such as acetone, toluene, chlorinated hydrocarbons, and formaldehyde-containing resins. The base component includes film-forming polymers, a monomer component compatible with the polymers, and a free radical source.Type: GrantFiled: June 16, 1997Date of Patent: April 18, 2000Assignee: Mycone Dental CorporationInventors: Mukesh Patel, Larry W.

Patent number: 5500212Abstract: New bile acid sequestrant polymer compositions and a process for preparing the polymers in particulate form, preferably in spherical form, are described. The polymer particles are prepared by crosslinking an amine-containing polymer with an amount of a polyfunctional amine-reactive compound sufficient to crosslink the polymer so that it is essentially water insoluble and has bile acid sequestering efficacy greater than that of cholestyramine, preferably greater than about three times the efficacy of cholestyramine. A preferred polymerization process revolves suspension polymerization of water-soluble amine-containing monomers, such as dialkylaminoalkyl (meth)acrylate esters and dialkylaminoalkyl (meth)acrylamides, in the presence of polyfunctional amine-reactive compounds, such as substituted dihaloalkanes. Pharmaceutical compositions containing the bile acid sequestrant polymer particles and a method for lowering blood cholesterol levels using the pharmaceutical compositions are also described.Type: GrantFiled: June 6, 1995Date of Patent: March 19, 1996Assignee: Rohm and Haas CompanyInventors: Paul E. Bliem, Larry W. Steffier
