Solvent Solutions for Nail Coating Removal
72 patents in this list
Updated:
Traditional nail coating removal systems rely heavily on acetone-based solvents that achieve rapid dissolution but can reduce nail plate hydration below 10% and compromise barrier integrity. These conventional formulations typically operate at solvent concentrations between 70-95%, creating challenges for both nail health and user comfort during the 5-15 minute removal process.
The fundamental challenge lies in developing removal agents that can effectively break polymer cross-links while maintaining nail plate moisture content and preventing protein denaturation.
This page brings together solutions from recent research—including emulsion-based systems with alkylene carbonates, gel formulations with thermoplastic resins, and biodegradable water-based removers with ethanolamide surfactants. These and other approaches focus on achieving effective coating removal while preserving nail plate integrity and user comfort.
