Yeast Cell Wall Composition for Wrinkle Repair and Skin Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions lack effective materials for improving skin wrinkles, retaining moisture, and providing a skin barrier while ensuring safety and natural origin.
Innovation Solution
A cosmetic composition containing a yeast cell wall, maintaining its shape, is used to improve skin wrinkles, retain moisture, and provide a skin barrier, with a particle size of 5 to 10 µm and a β-glucan content of 30% to 45% by weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If yeast cell wall is used as a cosmetic material, then skin wrinkle improving effect and moisture retention are achieved, but the complexity of material characterization and quality control increases due to maintaining cell wall shape
Solution Approach 1:
The patent specifies precise parameter ranges for the yeast cell wall composition: particle diameter of 5-10 μm and β-glucan content of 30-45% by weight. By controlling these parameters, the patent achieves reliable skin wrinkle improving effects while providing clear quality standards for manufacturing and inspection, thus resolving the contradiction between effectiveness and characterization complexity.
2Reliability
If yeast cell wall shape is maintained for skin barrier function, then occlusive property and moisture retention persistence are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent defines a specific particle size range of 5-10 μm for the yeast cell wall composition. This parameter control balances the need for maintaining cell wall shape (for skin barrier function) with manufacturability, providing clear specifications that guide production while ensuring the occlusive property and moisture retention persistence are achieved.
3Object-affected harmful factors
If food-grade yeast is used as the source, then safety and natural origin are ensured, but the variability in cell wall composition increases
Solution Approach 1:
The patent specifies a β-glucan content range of 30-45% by weight in the yeast cell wall composition. This parameter specification accommodates the natural variability of food-grade yeast while ensuring consistent safety and effectiveness. The range allows for composition variability inherent in natural sources while maintaining reliable skin care benefits.

AI summary
[Problem] To provide a material which utilizes a yeast-derived cell wall, has a skin wrinkle improving effect, and can be used as a feeling improver when applied to the skin. [Solution] As a result of intensive studies, the present inventors have found that, by using a yeast cell wall-containing composition having a yeast cell wall structure, a cosmetic composition having a skin wrinkle improving effect, a moisture retaining effect and a skin barrier effect can be provided, and that the cosmetic composition can also be used as a feeling improver. The present invention is completed based on these findings. Furthermore, yeast cell wall-containing composition according to the present invention can be extracted from yeast that has been used in foods. That is, the composition is derived from a microorganism capable of being used in foods, and therefore can be used safely.
