Tertiary Amine Wiping Composition for Rapid Microbial Kill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disinfectant wipes often require significant contact time to kill microorganisms and can leave streaks or film residue on surfaces, especially when premoistened, which complicates effective disinfection of hard surfaces.
Innovation Solution
A wiping composition containing a tertiary amine biocide, combined with organic solvents, evaporating agents, surfactants, and a liquid carrier, which provides quick disinfecting performance against hospital-grade microorganisms like Staphylococcus aureus and Pseudomonas aeruginosa, while minimizing streaking and achieving rapid efficacy against tuberculosis-causing bacteria like Mycobacterium tuberculosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If premoistened wipes are used for disinfection, then ease of operation is improved, but streaking and film residue increase
Solution Approach 1:
The patent modifies the chemical parameters of the wiping composition by using a water-miscible solvent system and adjusting the concentration of biocide and surfactant components. This creates a formulation that dries cleanly without streaking while maintaining ease of use in premoistened wipe format
Solution Approach 2:
The invention uses a composite formulation combining multiple components including biocide, water-miscible solvent, surfactant, and optional additives in specific proportions. This composite composition achieves both ease of operation and reduced harmful residues through synergistic interactions among components
2Reliability
If traditional antimicrobial compositions are used, then microbial control is achieved, but contact time is excessive
Solution Approach 1:
The patent changes the chemical parameters by selecting a water-miscible solvent system and optimizing biocide concentration, which enhances the rate of microbial kill and reduces the required contact time while maintaining reliable disinfection
Solution Approach 2:
The formulation is designed to rush through the disinfection process by using components that act quickly on microorganisms, achieving effective microbial control in a shortened contact time period
3Productivity
If disinfectant concentration is increased to improve kill rate, then productivity is improved, but streaking and residue increase
Solution Approach 1:
The patent optimizes the concentration parameters of the formulation, using a water-miscible solvent system that allows for effective biocide concentrations without causing excessive residue or streaking, thus maintaining high kill rate while minimizing harmful effects
Solution Approach 2:
The water-miscible solvent acts as an intermediary carrier that delivers the biocide effectively to microorganisms while being miscible with water and evaporating cleanly, preventing streaking and film residue even at concentrations that achieve rapid microbial kill
