Lactobacillus kefiranofaciens Cosmetic Composition for Skin Barrier Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for additional compounds in cosmetic products that can improve skin appearance, elasticity, and prevent signs of aging, as existing ingredients, such as chemical compounds and plant extracts, have limitations in effectiveness.
Innovation Solution
A cosmetic skin care composition containing non-viable components of Lactobacillus kefiranofaciens bacterial cells, including lysates and metabolic products like polysaccharides, proteins, and lipids, which are derived from inactivated bacteria, to reduce transepidermal water loss and enhance antioxidative potential.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical compounds are used in cosmetic products, then skin care effects are achieved, but effectiveness is limited and natural ingredients are preferred
Solution Approach 1:
The patent transforms bacterial cells from viable to non-viable state through inactivation, changing their physical state while retaining beneficial metabolic products. This resolves the contradiction by providing natural bacterial components that are safe for cosmetic use while maintaining effectiveness through preserved metabolic products like polysaccharides, proteins, and lipids.
Solution Approach 2:
The patent extracts and utilizes only the beneficial metabolic products and cell components from bacterial cells, separating them from the viable bacterial state. This extraction approach allows using natural bacterial components without the risks associated with living bacteria, satisfying both effectiveness and safety requirements.
2Reliability
If plant extracts are used to improve skin appearance, then moisturizing and soothing effects are achieved, but additional compounds are still needed for comprehensive skin care
Solution Approach 1:
The patent creates a composite cosmetic composition that integrates non-viable bacterial components with traditional plant extracts and other cosmetic ingredients. This composite approach combines the moisturizing and soothing properties of plant extracts with the unique benefits of bacterial metabolites like kefiran, providing comprehensive skin care that addresses multiple concerns simultaneously.
3Reliability
If bacterial ferments and lysates are used, then anti-aging and photoprotective effects are achieved, but transepidermal water loss and oxidative damage remain concerns
Solution Approach 1:
The patent utilizes non-viable bacterial components that perform multiple functions simultaneously: they provide anti-aging effects through metabolic products, reduce transepidermal water loss through barrier-forming polysaccharides like kefiran, and offer photoprotection through antioxidant compounds. This multi-functional approach resolves the contradiction by addressing multiple skin concerns with a single ingredient system.
