Multi-layer peelable nail polish with water-washable basecoat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peel-off nail polishes either have slower drying speeds and stability issues when incorporating pearlescent or glitter, or they cause damage to the nail plate due to strong adhesion, while traditional nail enamels require solvents for removal that can damage the nail.
Innovation Solution
A water-washable, non-UV curable nail basecoat composition containing a hydrophilic poly(N-vinyl)lactam polymer, alcohol, and plasticizer, paired with a colored non-UV curable nail colorcoat composition, allowing for rapid drying and easy removal without solvent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water-based nail polish is used, then solvent-free safety and ease of removal are improved, but drying speed and wear characteristics deteriorate
Solution Approach 1:
The patent uses a composite resin system combining two different resins (e.g., nitrocellulose or cellulose acetate butyrate with acrylic or vinyl acrylic copolymer) to achieve both water-washability and fast-drying properties. This composite approach allows the formulation to maintain rapid drying characteristics while being removable with water or mild soap, resolving the contradiction between safety and drying speed.
2Speed
If UV-curable nail polish is used, then drying speed and durability are improved, but nail plate damage during peeling occurs
Solution Approach 1:
The patent changes the fundamental parameter of the curing mechanism from UV-curing to air-drying/water-washable chemistry. By using a resin system that dries through evaporation and coalescence rather than photopolymerization, the formulation achieves rapid drying without creating the strong cross-linked adhesion that causes nail damage during removal. The water-washable chemistry allows gentle removal without defatting or damaging the nail plate.
3Duration of action of stationary object
If traditional nail enamel is used, then durability and shine are improved, but solvent removal is required which damages the nail
Solution Approach 1:
The patent employs a composite resin formulation combining natural resin (nitrocellulose or cellulose acetate butyrate) with synthetic polymer (acrylic or vinyl acrylic copolymer) to achieve both high durability and water-washable removal. This composite system provides the wear resistance and shine of traditional enamels while eliminating the need for harsh solvent removers, allowing gentle removal with water or mild soap.
4Illumination intensity
If pearlescent or glitter is incorporated, then appearance is improved, but stability issues occur in water-based formulations
Solution Approach 1:
The patent uses the composite resin system to provide a stable matrix for incorporating pearlescent and glitter effects. The combination of natural and synthetic resins creates a formulation that maintains suspension stability and prevents settling or degradation of appearance-enhancing particles, resolving the stability issues that plague water-based systems while preserving the cosmetic benefits.
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 fast-drying, durable, and solvent-free nail polish system that can be easily peeled off without damaging the nail, offering comparable benefits to traditional nail enamels while being safer and more environmentally friendly.
Implementation Method 1
