Polyglutamic Acid Compositions for Vaginal and Skin Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for vaginal and skin dryness, particularly in postmenopausal women, are inadequate as they often come with adverse effects such as vaginal bleeding, uterine cancer risks, vulvovaginal candidiasis, and bacterial vaginosis, and lack effective solutions for maintaining healthy moisture levels.
Innovation Solution
Compositions containing polyglutamic acid compounds with varying molecular weights are used to penetrate different layers of vaginal and skin tissues, providing superior results by maintaining healthy moisture levels and alleviating symptoms of dryness, itching, and burning, while avoiding adverse effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If topical estrogen therapy is used to treat vaginal dryness, then vaginal dryness is improved, but adverse effects such as vaginal bleeding and increased risk of uterine cancer occur
Solution Approach 1:
The patent introduces polyglutamic acid as an intermediary substance that provides the moisturizing benefits of estrogen without the harmful effects. Polyglutamic acid acts as a mediator that delivers hydration and moisture to vaginal tissues while avoiding the carcinogenic and bleeding risks associated with direct estrogen therapy.
Solution Approach 2:
The patent employs a non-hormonal, biodegradable polyglutamic acid composition that can be used repeatedly without accumulating harmful effects in the body. This disposable-like approach allows continuous use without the long-term cancer risks associated with estrogen therapy.
2Object-affected harmful factors
If hyaluronic acid is used as an alternative therapy for vaginal dryness, then vaginal dryness is improved, but adverse effects including vulvovaginal candidiasis and bacterial vaginosis occur
Solution Approach 1:
Polyglutamic acid serves as an alternative intermediary substance that provides moisture without disrupting the vaginal microbiome. Unlike hyaluronic acid, it does not promote fungal or bacterial overgrowth, thereby avoiding candidiasis and vaginosis while still effectively treating dryness.
Solution Approach 2:
The patent changes the chemical composition parameter from hyaluronic acid to polyglutamic acid, which alters the interaction with vaginal flora. This parameter change results in a composition that maintains moisture while preserving microbial balance, eliminating the adverse effects associated with hyaluronic acid.
3Object-generated harmful factors
If polyglutamic acid compositions are used to treat vaginal dryness, then adverse effects are avoided, but penetration effectiveness through different tissue layers must be maintained
Solution Approach 1:
The patent segments the polyglutamic acid composition into different molecular weight fractions that can penetrate different tissue depths. This segmentation ensures that smaller molecules reach deeper vaginal tissues while larger molecules provide surface moisturizing, maintaining penetration effectiveness across all tissue layers without adverse effects.
Solution Approach 2:
The patent utilizes parameter changes in molecular weight and chain length of polyglutamic acid to optimize penetration. By adjusting these parameters, the composition effectively penetrates various tissue depths while maintaining safety, resolving the contradiction between avoiding adverse effects and ensuring reliable penetration.
4Object-affected harmful factors
If polyglutamic acid compositions are used to treat skin dryness, then skin moisture is improved, but the composition must penetrate multiple skin layers effectively
Solution Approach 1:
The patent divides the polyglutamic acid into multiple molecular weight segments that correspond to different skin layers. This segmentation allows the composition to systematically penetrate from the epidermis through the dermis, addressing skin dryness at multiple levels without excessive formulation complexity.
Solution Approach 2:
The patent adds the dimension of molecular size variation to the polyglutamic acid composition, enabling it to penetrate skin layers of different depths. This dimensional approach to molecular weight creates a gradient of penetration capability that simplifies the overall treatment mechanism while effectively addressing multi-layer skin dryness.
