Innovation Solution
A composition combining a surfactant compound represented by Formula 1 with preservative compounds represented by Formulas 2, 3, 4, or 5, which provides synergistic antimicrobial, disinfecting, and antiseptic effects, effectively controlling a wide range of microorganisms while minimizing human harm and skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antimicrobial agents (isothiazolinone ingredients) are used, then potent antimicrobial effects and economic efficiency are achieved, but harmfulness to human body and carcinogenic risk increase
Solution Approach 1:
The patent combines multiple preservative ingredients (isothiazolinone derivatives with other antimicrobial agents) to create a composite preservative system that maintains potent antimicrobial effectiveness while reducing the harmful effects and carcinogenic risk associated with single-agent use. This composite approach allows for synergistic effects that enhance safety profile.
Solution Approach 2:
The patent modifies the chemical parameters of preservative ingredients by using specific derivatives and combinations (e.g., methylisothiazolinone with chloromethylisothiazolinone in specific ratios) to change the safety profile while maintaining antimicrobial potency. This includes adjusting concentration ratios and molecular structures to reduce toxicity.
2Object-affected harmful factors
If antimicrobial agents are not used or weak antimicrobial property is applied, then safety concerns are reduced, but product deterioration and pathogen transmission risk increase
Solution Approach 1:
The patent employs composite preservative systems that provide broad-spectrum antimicrobial protection against bacteria, fungi, and algae while maintaining safety. The combination of different preservative mechanisms in one system ensures product stability without requiring high concentrations of single potent agents.
Solution Approach 2:
The preservative composition is designed to provide multiple functions simultaneously: preventing product deterioration, inhibiting pathogen transmission, and maintaining safety. The composite formula addresses multiple protection needs with a single integrated system.
3Object-affected harmful factors
If highly safe antimicrobial agents are selected, then harmfulness to human body is reduced, but application scope is narrowed due to regulations
Solution Approach 1:
The patent creates a versatile preservative composition that can be applied across multiple product types (cosmetics, personal care, household products) by combining safe preservative agents in synergistic ratios. This composite approach maintains broad adaptability while meeting stringent safety requirements.
Solution Approach 2:
The patent adjusts the chemical parameters and concentration ratios of preservative ingredients to optimize both safety and versatility. By modifying the composition parameters, the preservative system achieves broad applicability across different product formulations while maintaining low toxicity.
