Solution Overview
Problem
Existing antimicrobial agents used in products are harmful to human health and the environment, and there is a need for safer alternatives that effectively control bacteria, viruses, and dandruff-causing fungi while minimizing environmental impact.
Innovation Solution
A composition containing compounds represented by Formulas 1, 2, and 4, which exhibit synergistic antibacterial, antiviral, and antifungal effects, reducing the need for toxic chemicals like isothiazolinones and expensive agents like piroctone olamine and zinc pyrithione.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If isothiazolinone ingredients are used as preservatives, then antimicrobial effectiveness is improved, but human health safety deteriorates due to carcinogenic potential
Solution Approach 1:
The patent changes the chemical parameters by replacing isothiazolinone ingredients with compounds having specific molecular structures (Formula 1: C7-C17 alkyl/alkenyl groups with hydroxyl or carboxyl terminals). This structural parameter change maintains antimicrobial effectiveness while eliminating carcinogenic properties, resolving the contradiction between reliability and safety
Solution Approach 2:
The patent employs alternative preservative compounds that can be used at higher concentrations without long-term accumulation concerns, replacing the need for highly potent but toxic isothiazolinones. These alternative compounds achieve sufficient antimicrobial protection through their specific molecular structures without the harmful long-term effects
2Object-affected harmful factors
If antimicrobial agents are not used or weak antimicrobial property is used, then human health safety is improved, but product deterioration risk increases
Solution Approach 1:
The patent modifies the chemical parameters of preservative agents by using compounds with specific functional groups (hydroxyl, carboxyl) and carbon chain lengths (C7-C17). These parameter changes enable the use of milder preservatives that maintain product stability without the severe health risks associated with traditional strong antimicrobials
Solution Approach 2:
The patent employs composite preservative systems combining multiple compounds with different mechanisms of action. This composite approach allows for reduced individual concentrations of each agent, maintaining overall product stability while minimizing health risks through synergistic effects
3Reliability
If piroctone olamine and zinc pyrithione are used for dandruff treatment, then antifungal effectiveness is improved, but product cost increases
Solution Approach 1:
The patent changes the chemical parameters by using compounds with specific structures (Formula 1 with C7-C17 chains) that naturally exhibit antifungal activity against Malassezia species. These structurally optimized compounds achieve comparable effectiveness to expensive agents like piroctone olamine and zinc pyrithione at lower costs
Solution Approach 2:
The patent employs cost-effective alternative compounds that can be produced through simpler synthesis routes or obtained from natural sources. These compounds provide sufficient antifungal protection for dandruff treatment without the high manufacturing costs associated with patented molecules like piroctone olamine
