Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic and pharmaceutical products lack effective, toxicologically safe, and stable antimicrobial agents that can inhibit or kill microorganisms causing body odor, such as Staphylococcus epidermidis, Corynebacterium xerosis, and Brevibacterium epidermidis, without causing skin irritation or discoloration.
Innovation Solution
The development of 3-(4-hydroxy-3-methoxyphenyl)-1-(4-hydroxyphenyl)-1-propanone, a compound with excellent antimicrobial properties, high stability across various temperatures and pH ranges, and a weak vanilla-like odor, suitable for use in cosmetic and pharmaceutical formulations, which is produced through an aldol condensation reaction followed by hydrogenation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antimicrobial agents are used to inhibit microorganisms causing body odor, then antimicrobial activity is achieved, but toxicological safety and skin compatibility deteriorate
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of known antimicrobial compounds (such as dihydrochalcones and flavonoids) through specific substitution patterns and functional groups to achieve optimal balance between antimicrobial activity and skin compatibility. The compound 3-(4-hydroxy-3-methoxyphenyl)-1-(4-hydroxyphenyl)-1-propanone represents a specific parameter optimization that maintains efficacy while improving safety profile.
2Reliability
If strong antimicrobial agents are used to kill odor-forming bacteria, then antimicrobial efficacy is improved, but skin irritation and discoloration increase
Solution Approach 1:
The patent applies local quality by introducing specific functional groups (hydroxy, methoxy) at particular positions on the molecular structure to create localized regions of desired chemical properties. This allows the compound to exhibit strong antimicrobial activity at specific interaction sites while maintaining overall gentleness and stability toward skin tissues.
Solution Approach 2:
The patent employs composite material principles by combining multiple functional groups (ketone, hydroxy, methoxy) within a single molecular framework to achieve a compound that integrates antimicrobial efficacy with skin compatibility and color stability in cosmetic formulations.
3Reliability
If existing antimicrobial substances are applied to inhibit sweat bacteria, then deodorant effect is achieved, but stability in cosmetic formulations deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing the chemical structure to achieve pH stability across a wide range (pH 3-10) and thermal stability up to 80°C, ensuring the compound remains effective and stable in various cosmetic formulation conditions while maintaining its deodorant function.
