Herb Extract Mixture Synergistic Antioxidant Activity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antioxidant compositions in personal care products, including herb extracts, often fail to provide synergistic antioxidant effects, limiting their overall antioxidant activity when used individually.
Innovation Solution
Combining sophora herb extracts with honeysuckle, kudzu, or licorice extracts in specific concentration ratios to achieve synergistic antioxidant effects, as demonstrated by the oxygen radical absorbance capacity (ORAC) assay, which enhances the total antioxidant activity beyond their individual contributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual herb extracts are used in personal care products, then they provide basic antioxidant properties, but they fail to achieve synergistic antioxidant effects and have limited total antioxidant activity
Solution Approach 1:
The patent combines sophora extract with at least one other herb extract (honeysuckle, kudzu, or licorice) to create a synergistic mixture. This merging of multiple herb extracts produces an antioxidant effect greater than the sum of individual components, directly resolving the limitation of using single herb extracts with limited antioxidant activity.
Solution Approach 2:
The invention creates a composite antioxidant system by formulating specific combinations of herb extracts (sophora with honeysuckle, kudzu, or licorice) in defined concentration ranges. This composite approach leverages the complementary properties of different herbs to achieve enhanced and synergistic antioxidant protection against free radicals.
2Reliability
If multiple herb extracts are combined to enhance antioxidant effects, then synergistic antioxidant activity is achieved, but the formulation complexity increases
Solution Approach 1:
The patent specifies particular concentration ranges for each herb extract in the combination (sophora at 0.1-10% w/w and the second herb at 0.1-5% w/w). This local quality control ensures optimal synergistic effects while maintaining manageable formulation complexity through defined parameter ranges rather than open-ended combinations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combination of sophora with honeysuckle, kudzu, or licorice extracts within certain concentration ranges exhibits synergistic antioxidant effects, significantly increasing the total antioxidant activity, as shown by positive percentage increases in ORAC values, indicating enhanced protection against free radicals and skin aging.
Implementation Method 1
mixtures of herb extracts which exert synergistic antioxidant effect and comprise the herb sophora and at least one other herb selected from the group consisting of honeysuckle, kudzu, and licorice
Data Source
