Hypochlorous Acid Hand Sanitizer Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sanitizers face challenges in effectively disinfecting surfaces, particularly hands, due to the development of resistant microorganisms and limitations such as water usage, skin dryness, and undesirable properties of alcohol-based sanitizers like fumes and irritation.
Innovation Solution
A sanitizing formulation comprising hypochlorite, sodium magnesium silicate, and a silicone polymer blend, which includes dimethicone and cyclomethicone, is developed to provide effective disinfection against drug-resistant microorganisms without requiring water for removal and minimizing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alcohol-based sanitizers are used for disinfection, then microbial destruction is effective, but skin irritation and undesirable fumes occur
Solution Approach 1:
The patent changes the chemical composition parameters by replacing alcohol with hypochlorite (5-500 ppm), sodium magnesium silicate (0.1-10%), and silicone polymer (0.1-10%) to achieve effective disinfection without the harmful effects of alcohol-based sanitizers, including skin irritation and undesirable fumes
Solution Approach 2:
The invention uses a composite formulation combining hypochlorite, sodium magnesium silicate, and silicone polymer to achieve synergistic effects that provide effective disinfection while minimizing harmful side effects, creating a multi-component system that addresses both efficacy and safety requirements
2Reliability
If soap is used for removing microorganisms, then disinfection is effective, but large quantities of water are required
Solution Approach 1:
The patent extracts the essential disinfection function from water-based soap systems by using a waterless or reduced-water formulation with hypochlorite and sodium magnesium silicate that provides effective microorganism removal without requiring large quantities of water for rinsing
Solution Approach 2:
The sanitizer formulation is designed to self-rinse or evaporate without requiring water for removal, with the silicone polymer and sodium magnesium silicate components facilitating easy removal from skin while maintaining disinfection effectiveness
3Reliability
If frequent soap washing is performed, then microorganism removal is effective, but skin dryness and irritation increase
Solution Approach 1:
The patent changes the formulation parameters by using hypochlorite at low concentrations (5-500 ppm) combined with sodium magnesium silicate and silicone polymer, which provides effective sanitization while being gentler on skin compared to frequent soap washing, thereby reducing skin dryness and irritation
Solution Approach 2:
The sanitizer is designed as a disposable or frequently replaceable product that eliminates the need for repeated water-based washing, with the formulation providing sufficient disinfection in single or limited applications to avoid cumulative skin damage from frequent soap use
