Alcohol-Removable Nail Gel Formulation for Safe Solvent-Free Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current one-step nail gel polish removers contain toxic solvents like acetone, ethyl acetate, and butyl acetate, causing damage and health issues, and require lengthy soak-off times, which is detrimental to nails and skin.
Innovation Solution
An alcohol-removable nail gel polish is developed using a formulation of isobornyl acrylate, hydroxyethyl methacrylate, trimethylolpropane triacrylate, (2,4,6-trimethylbenzoyl)diphenyl phosphine oxide, aliphatic urethane acrylate, cellulose acetate butyrate, and pigments, which can be cured under UV or LED light and removed using a 70-80% alcohol solution, eliminating the need for toxic solvents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional removers containing acetone, ethyl acetate, and butyl acetate are used, then the gel polish can be removed, but the remover causes damage to nails and skin and has harmful effects on human health
Solution Approach 1:
The patent changes the chemical composition parameters of the remover by replacing toxic solvents (acetone, ethyl acetate, butyl acetate) with alcohol-based solvents. This parameter substitution maintains the removal function while eliminating harmful effects on nails and skin, directly resolving the contradiction between removal effectiveness and health safety.
Solution Approach 2:
The patent uses a composite alcohol-based solvent system comprising multiple alcohol components (ethyl alcohol, isopropyl alcohol, or n-propanol) in specific proportions. This composite formulation achieves effective gel removal while being gentler on nails and skin compared to conventional single-solvent toxic formulations.
2Loss of time
If conventional removers are used, then the gel polish can be removed, but the soak-off time is lengthy (8-15 minutes) which causes damage and discomfort
Solution Approach 1:
The patent modifies the solvent parameters by using alcohol-based solvents with different chemical properties compared to conventional esters and ketones. This change in solvent parameters enables effective gel removal while reducing the harmful exposure time and damage to nails and skin during the removal process.
3Ease of operation
If one-step gel polish is applied for easy and fast application, then the application process is simplified and time-saving, but the removal process requires toxic solvents and lengthy soak-off
Solution Approach 1:
The patent changes the chemical parameters of the removal system by formulating alcohol-based solvents that can effectively remove one-step gel polish without requiring toxic substances. This maintains the simplicity and speed advantages of one-step application while eliminating the harmful removal process.
Solution Approach 2:
The patent converts the potential harm of requiring strong solvents for one-step gel removal into a benefit by using alcohol-based solvents that are both effective for removal and safe for health. The alcohol solvents provide sufficient removal power while being gentler than conventional toxic solvents, turning a harmful requirement into a beneficial solution.
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 alcohol-removable nail gel polish offers a safe, environmentally friendly, and healthy removal process with short curing times and long-lasting wear, while avoiding damage to nails and skin, and can be easily applied at home with a three-in-one application.
Implementation Method 1
it can be fully cured by irradiation of ordinary UV or UV-LED light sources within a few minutes
Implementation Method 2
can be removed with alcohol solution (e.g., about 75% alcohol) which does not contain acetone, ethyl acetate, butyl acetate or toxic solvent

AI summary
An alcohol-removable nail gel comprising the following components in percent by weight:isobornyl acrylate 10-15%hydroxyethyl methacrylate 15-25%trimethylolpropane triacrylate 5-15%(2,4,6-trimethylbenzoyl)diphenylphosphine oxide 5-15%aliphatic urethane acrylate 20-30%cellulose acetate butyrate 15-20%pigments 1-15%. The alcoholremovable gel polish, similar in application and function as common one-step gel polish, can be removed with alcohol solution which does not contain acetone, ethyl acetate, butyl acetate or other toxic solvents. Using alcohol-soaked cotton to wrap nails for 10-15 min, the process is environmentally friendly, safe, healthy and not detrimental to human body.
