Polyglutamic Acid Compositions for Layered Vaginal Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for vaginal dryness, such as topical estrogen therapy and hyaluronic acid, carry risks and adverse effects, making them insufficient for many women, particularly postmenopausal women.
Innovation Solution
Compositions containing polyglutamic acid compounds with varying molecular weights are formulated to penetrate different layers of vaginal epithelial tissue, providing relief from vaginal dryness, itching, and burning, and maintaining moisture levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If topical estrogen therapy is used to treat vaginal dryness, then vaginal moisture is improved, but adverse effects such as vaginal bleeding and increased risk of uterine cancer occur
Solution Approach 1:
The patent changes the chemical composition parameter by using polyglutamic acid instead of estrogen, fundamentally altering the active ingredient to eliminate harmful effects while maintaining the desired moisture-enhancing function
Solution Approach 2:
The patent employs a safe, non-hormonal alternative that can be used without the long-term health risks associated with estrogen therapy, effectively replacing a harmful substance with a benign one
2Quantity of substance
If hyaluronic acid is used to treat vaginal dryness, then vaginal moisture is improved, but adverse effects including vulvovaginal candidiasis and bacterial vaginosis occur
Solution Approach 1:
The patent changes the chemical composition by substituting hyaluronic acid with polyglutamic acid, altering the molecular structure to eliminate the adverse effects while preserving the moisturizing function
Solution Approach 2:
The patent replaces hyaluronic acid with a safer polyglutamic acid alternative that does not promote fungal or bacterial infections, providing a benign substitution
3Quantity of substance
If polyglutamic acid compositions are used to treat vaginal dryness, then vaginal moisture is improved without adverse effects, but the compositions must penetrate varying layers of vaginal epithelial tissue
Solution Approach 1:
The patent segments the polyglutamic acid into different molecular weight fractions (low, medium, high) that can penetrate different layers of the vaginal epithelium, dividing the penetration function into distinct molecular components
Solution Approach 2:
The patent applies local quality by matching specific molecular weight ranges to specific tissue layers, where low molecular weight polyglutamic acid penetrates the stratum corneum, medium weight penetrates the stratum granulosum, and high weight remains in the stratum spinosum
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 polyglutamic acid compositions effectively penetrate and moisturize vaginal tissues, offering fast and long-lasting relief from symptoms of vaginal dryness and associated menopausal symptoms without adverse effects.
Implementation Method 1
The molecular weight of each polyglutamic acid compound is determined by the number of the glutamic acid monomers that have been linked
Implementation Method 2
the compounds' ability to penetrate varying layers of vaginal epithelial tissue depending upon the particular ratio of polyglutamic acid compounds having different n values
