  • Artificial nail compositions and related methods
    Patent number: 8124058
    Abstract: The invention comprises a polymerizable monomer composition for application to the nail surface and polymerization thereon to yield an artificial nail structure, comprising at least one multicarbonyl-vinyl containing monomer; a polymerized artificial nail structure having a thickness of about 10-60 mils, and a modulus of elasticity of about 550-800 N/m2, comprising a copolymer of at least one ethylenically unsaturated monomer and a multicarbonyl vinyl-containing monomer; a method for reducing, ameliorating, or eliminating delamination of an artificial nail structure from the natural nail surface; a method for improving adhesion of an artificial nail structure to the nail surface; and a method for reducing premature gelation of a liquid monomer composition.
    Type: Grant
    Filed: November 15, 2004
    Date of Patent: February 28, 2012
    Assignee: Creative Nail Design, Inc.
    Inventors: Douglas Dean Schoon, George Frederick Cowperthwaite, Allen David Johnston, Susan C. Sheariss, Jennifer Ellen Moore
