Acrylic Nail Composition Reducing Odor and Curing Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional acrylic nail enhancement systems face issues with strong odor, poor handling characteristics, and visual defects due to high vapor pressure monomers like EMA, leading to incomplete association of monomer and polymer components, resulting in unsatisfactory surface hardness and prolonged curing times, which are not suitable for salon use.
Innovation Solution
A composition comprising a polymer component formed from (meth)acrylate esters with specific alkyl side chains and an initiator, and a monomer component with di-, tri-, or multi-functional (meth)acrylate esters, which reduces odor and improves solvency, solubility, and curing properties, allowing for a homogeneous mixture with enhanced application characteristics and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional high vapor pressure monomers like EMA are used, then the nail enhancement system achieves good solvency and curing properties, but it produces strong odor and poor handling characteristics
Solution Approach 1:
The patent changes the chemical parameters of the monomer by using lower vapor pressure alternatives (such as propyl (meth)acrylate, butyl (meth)acrylate, or isopropyl alcohol) while adjusting the formulation to maintain adequate solvency and curing properties, thereby reducing odor without sacrificing performance
Solution Approach 2:
The patent creates a composite monomer system combining multiple components (e.g., propyl (meth)acrylate, butyl (meth)acrylate, isopropyl alcohol, and functional monomers) to achieve both low odor and adequate handling characteristics through synergistic effects
2Manufacturing precision
If conventional monomer-polymer systems are used, then the composition achieves adequate curing, but it results in incomplete association of monomer and polymer components leading to visual defects and poor surface hardness
Solution Approach 1:
The patent optimizes the molecular weight and chemical structure parameters of both monomer and polymer components to enhance their mutual association and complete reaction, thereby eliminating visual defects and achieving superior surface hardness
Solution Approach 2:
The patent introduces functional monomers and additives that act as intermediaries to facilitate complete association between monomer and polymer components, ensuring thorough reaction and eliminating defects in the final product
3Loss of time
If conventional acrylic nail enhancement systems are used, then the application process is straightforward, but it requires prolonged curing times and results in tacky surfaces
Solution Approach 1:
The patent changes the chemical composition parameters by incorporating functional monomers and adjusting the monomer-to-polymer ratio to accelerate the curing reaction, thereby reducing curing time and eliminating tackiness while maintaining ease of application
