Boron Compounds Enhance Preservative Effect in Liquid Detergents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid detergents require high concentrations of antimicrobial preservatives to prevent mold formation and phase separation, which can be ecologically harmful, and existing solutions fail to optimize preservative usage effectively.
Innovation Solution
The use of boron-containing compounds, such as boric acid and boronic acids, enhances the preservative effect of 2-phenoxyethanol, allowing for reduced preservative amounts without compromising effectiveness in detergents and cleaning agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of antimicrobial preservatives are used to prevent mold formation and phase separation, then the effectiveness of preservative is improved, but the ecological compatibility deteriorates
Solution Approach 1:
Boron-containing compounds act as an intermediary substance that enhances the preservative effect of 2-phenoxyethanol. The boron compound interacts with the preservative to create a synergistic effect, allowing reduced preservative concentration while maintaining or improving antimicrobial protection. This mediator approach resolves the contradiction by introducing a third substance that amplifies the preservative's effectiveness at lower doses.
Solution Approach 2:
The invention creates a composite preservative system combining 2-phenoxyethanol with boron-containing compounds. This composite formulation produces a synergistic effect where the combination is more effective than the sum of individual components, enabling reduced overall preservative concentration while maintaining protection against mold and phase separation, thus improving ecological compatibility.
2Reliability
If high concentrations of preservatives are used to ensure product stability, then the reliability is improved, but the quantity of harmful substances increases
Solution Approach 1:
The boron-containing compound serves as an intermediary that amplifies the preservative action of 2-phenoxyethanol. By introducing this mediator, the system achieves enhanced product stability against microbial contamination and phase separation at lower overall preservative concentrations, reducing the quantity of harmful substances in the final product.
Solution Approach 2:
The invention changes the chemical composition parameters by introducing boron-containing compounds with specific molecular structures (formula I). This parameter change creates a new preservative system with different efficacy characteristics, allowing stable product formulation at reduced preservative concentrations through the synergistic interaction between the boron compound and 2-phenoxyethanol.
