Removable Nail Basecoat Using Solvent-Dissolvable Resin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail coatings either lack the ease of removal of nail polishes or require harsh methods to remove artificial nails, which are durable and resistant.
Innovation Solution
A 3-D thermoset lattice interpenetrated by an organic solvent-dissolvable resin, incorporating polymers like PMMA and PMAA, and non-reactive solvent-dissolvable polymers, facilitates enhanced adhesion and easy solvent-based removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional artificial nails use 100% solids thermoset compositions without non-reactive solvents, then adhesion and durability are enhanced, but removal time and difficulty increase significantly
Solution Approach 1:
The patent segments the nail coating system into multiple functional layers: a basecoat layer containing organic solvent-dissolvable resin for easy removal, and an overlay layer containing the durable thermoset composition. This segmentation allows each layer to perform its specific function - the basecoat provides adhesion and enables quick removal, while the overlay provides durability and aesthetics.
Solution Approach 2:
The patent introduces an intermediary substance - an organic solvent-dissolvable resin (such as cellulose acetate butyrate) - that acts as a mediator between the natural nail and the durable thermoset overlay. This intermediary layer can be rapidly dissolved by organic solvents like acetone, enabling quick removal of the entire nail enhancement system without damaging the natural nail.
2Strength
If conventional artificial nails create highly durable cross-linked thermoset coatings, then scratch and solvent resistance are improved, but ease of removal deteriorates
Solution Approach 1:
The patent divides the coating system into two segments with different property profiles: a basecoat segment that is deliberately made soluble in organic solvents for easy removal, and an overlay segment that provides the desired scratch and solvent resistance. This segmentation resolves the contradiction by allowing the durable portion to resist scratches while the soluble basecoat enables easy removal.
Solution Approach 2:
The patent applies local quality by giving different regions of the nail coating system different chemical properties. The basecoat layer near the natural nail is formulated with organic solvent-dissolvable resin to facilitate removal, while the overlay layer is formulated with cross-linked thermoset for durability. Each layer has locally optimized properties for its specific function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a nail coating that adheres well and is durable like artificial nails but can be quickly and gently removed without abrasion, using organic solvents to 'unzip' the polymerized lattice, reducing removal time significantly.
Implementation Method 1
an interconnected system of voids and an interpenetrating network of an organic solvent-dissolvable resin provides ease of solvent removability
Implementation Method 2
a liquid composition comprising at least one monomer, and/or oligomer, and/or polymer which polymerize to a 3-D thermoset

AI summary
The present disclosure relates generally to compositions for natural and artificial nail coatings, and particularly, but not by way of limitation, to polymerizable compositions and adhesion-promoting basecoats polymerized therefrom. The disclosure further relates to methods of making a polymerized basecoat that are more easily removed than artificial nail enhancements and more durable and long lasting than nail polish coatings.
