Artificial Nail Composition Using Interference Pigments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial nail compositions using gel nails with organic and/or inorganic colorants that utilize absorbing and/or scattering phenomena of light fail to meet aesthetic demands due to monotonous color tones and deterioration of color and transparency over time, while existing dental resin-based materials suffer from irritation and poor operability.
Innovation Solution
An artificial nail composition comprising a compound with radical polymerizable unsaturated double bonds, a radical polymerization initiator, an organic and/or inorganic colorant utilizing absorbing and/or scattering phenomena of light, and an inorganic colorant with interference properties, which enhances reflection of specific wavelengths to achieve vivid, natural color tones and improved durability and operability.

Engineering Contradiction Analysis
1Illumination intensity
If conventional gel nail products use organic and/or inorganic colorants utilizing absorbing and/or scattering phenomena of light, then the color and transparency are maintained, but the color tones become monotonous and fail to meet aesthetic demands
Solution Approach 1:
The patent combines multiple types of inorganic colorants (metallic pigments, pearl pigments, and interference pigments) within a single gel nail composition. This composite approach allows the formulation to achieve both color depth from absorbing/scattering pigments and vivid, natural color tones with transparent sensation from interference pigments, thereby meeting high aesthetic demands while maintaining a unified product structure.
Solution Approach 2:
The patent utilizes interference pigments that produce color changes through light interference phenomena. These pigments create vivid, natural color tones that shift and shimmer, providing dynamic visual effects that static absorbing/scattering pigments cannot achieve. This color change mechanism enables the composition to meet aesthetic demands for vibrancy and natural appearance.
2Reliability
If dental resin-based artificial nail materials are used, then strength and durability are improved, but irritation and poor operability occur
Solution Approach 1:
The patent changes the chemical composition parameters by using gel-based monomers instead of traditional dental resins. This parameter change maintains the durability and strength requirements while eliminating the harmful acryl monomer components that cause skin irritation and odor. The gel-based formulation provides comparable mechanical properties without the adverse biological effects.
Solution Approach 2:
The patent adopts a gel nail formulation that can be easily applied and removed compared to traditional dental resins. This approach treats the nail enhancement as a temporary, disposable application that prioritizes user comfort and ease of removal over permanent durability, thereby reducing skin irritation and odor issues associated with long-lasting dental resin products.
3Ease of operation
If gel nail compositions are used, then odor irritation and operability are improved, but color tones cannot meet aesthetic demands
Solution Approach 1:
The patent creates a composite colorant system within the gel nail composition that combines absorbing/scattering pigments with interference pigments. This composite approach maintains the ease of operation and low irritation benefits of gel nails while significantly enhancing color tone aesthetic appeal through the synergistic effects of different pigment types working together.
Solution Approach 2:
The patent uses interference pigments that replicate and enhance natural nail coloration effects. These pigments create vivid, natural color tones that mimic healthy nail appearance, allowing the gel nail composition to meet high aesthetic demands while maintaining the operational ease and comfort benefits of gel-based formulations.
