Sulfonated Polyester Resin Nail Polish for Safer Fast Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail polish compositions pose safety hazards and environmental concerns due to flammability and toxicity of organic solvents like nitrocellulose, toluene, and phthalates, and are slow-drying, necessitating the development of safer, more environmentally-friendly alternatives with faster setting film-forming agents that maintain adhesion and glossiness.
Innovation Solution
An aqueous-based nail polish composition utilizing sulfonated polyester resins, such as sodio-sulfonated polyesters and co-polyester-co-polysiloxanes, which are odorless, non-toxic, and form robust films, reducing the need for organic solvents and providing fast drying without compromising adhesion or glossiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional organic solvent-based nail polish compositions are used, then good adhesion and fast drying are achieved, but safety hazards and environmental concerns arise due to flammability and toxicity
Solution Approach 1:
The patent changes the fundamental parameter of the solvent system from organic solvents to water-based solvents. This substitution eliminates flammability and reduces toxicity while maintaining the film-forming capability through specially designed water-soluble or water-dispersible polymers and resins that can adhere to nails without requiring traditional organic solvents
Solution Approach 2:
The patent extracts and removes the harmful organic solvent components (nitrocellulose, toluene, formaldehyde, phthalates) from the nail polish composition entirely, replacing them with safe water-based alternatives. This extraction eliminates the safety hazards while preserving the essential functions of adhesion, color, and gloss through different chemical mechanisms
2Object-affected harmful factors
If aqueous-based nail polish compositions are used, then safety and environmental friendliness are improved, but drying time increases and becomes slow
Solution Approach 1:
The patent employs composite material systems that combine water-soluble polymers, resins, and film-forming agents specifically designed to work in aqueous environments. These composite formulations include multiple components that work synergistically to provide fast drying through controlled evaporation and film formation mechanisms while maintaining safety and environmental compatibility
Solution Approach 2:
The patent modifies the physical and chemical parameters of the aqueous system to optimize drying time. This includes adjusting polymer molecular weight, cross-linking density, and film-forming kinetics to enable faster water evaporation and quicker film formation compared to conventional aqueous systems, thereby reducing the perceived drying time without compromising safety
3Reliability
If nitrocellulose is used as film-forming agent, then good adhesion to nails is achieved, but flammability increases and safety hazards arise
Solution Approach 1:
The patent completely removes nitrocellulose and other flammable film-forming agents from the composition. Instead, it uses water-soluble polymers and resins that provide equivalent or superior adhesion through hydrogen bonding, dipole interactions, and physical anchoring to the nail surface, eliminating the flammability hazard entirely
Solution Approach 2:
The patent employs film-forming agents that are water-soluble and designed to form temporary protective films on the nail surface. These films provide adequate adhesion and protection for the intended wear period and then safely degrade or can be easily removed without leaving harmful residues, replacing the need for persistent, flammable film-formers like nitrocellulose
4Loss of time
If organic solvents like toluene are used, then fast drying time is achieved, but unpleasant odor and toxicity increase
Solution Approach 1:
The patent changes the solvent parameter from volatile organic compounds to water as the primary solvent. This substitution eliminates the unpleasant odor associated with toluene and other organic solvents while maintaining acceptable drying times through optimized film-forming chemistry that allows for rapid water evaporation and film formation without requiring highly volatile, odorous organic solvents
