Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited water solubility of phenolic compounds, such as polyphenols, restricts their applications in cosmetics and other uses, as existing methods like delivery systems and chemical modifications either require specific systems, increase costs, or reduce the compounds' activity, and solubilizers like organic solvents pose safety concerns.
Innovation Solution
Incorporating hydrotropes like nicotinamide, caffeine, sodium PCA, sodium salicylate, urea, or hydroxyethyl urea into aqueous compositions to significantly enhance the water solubility of phenolic compounds, allowing for their effective formulation in cosmetic and food applications without stability issues upon dilution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If delivery systems or chemical modifications are used to improve solubility of phenolic compounds, then water solubility is improved, but manufacturing costs increase and/or biological activity is reduced
Solution Approach 1:
The patent introduces hydrotropes as intermediary substances that mediate between phenolic compounds and water. These hydrotropes form mixed micelles or solubilization complexes that enable phenolic compounds to dissolve in water without chemical modification, thereby improving solubility while avoiding the costs and activity loss associated with chemical modification approaches.
Solution Approach 2:
The patent changes the physical-chemical parameters of the aqueous system by introducing hydrotropes that alter the solvent properties of water. This allows phenolic compounds to achieve high solubility in water through physical mixing rather than chemical modification, reducing manufacturing complexity and preserving biological activity.
2Quantity of substance
If strong organic solvents or diterpene glycosides are used as solubilizers, then water solubility of phenolic compounds is improved, but safety and cosmetic compatibility are compromised
Solution Approach 1:
The patent employs hydrotropes that are cosmetically acceptable and safe for use, replacing strong organic solvents that pose safety concerns. These hydrotropes can be used in cosmetic formulations without compromising safety, effectively acting as safe, temporary solubilizing agents that fulfill the solubility requirement without the harmful effects of traditional solvents.
3Quantity of substance
If traditional solubilizers are used in aqueous compositions, then solubility of phenolic compounds is improved initially, but solubility decreases dramatically when additional water is added
Solution Approach 1:
The patent employs hydrotropes that provide universal solubilization capability across different water concentrations. These hydrotropes maintain their solubilizing function even when the composition is diluted with additional water, unlike traditional solubilizers that fail upon dilution. This multi-functionality allows the formulation to remain stable and effective across various application conditions.
