Sunscreen Composition Using Trans-Resveratrol Polysaccharide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sunscreen cosmetic compositions with high UV protection agents suffer from poor spreadability, stickiness, and white cast issues, and the mass production of glycosylated resveratrol derivatives is impractical due to insufficient water solubility.
Innovation Solution
An emulsified cosmetic composition combining trans-resveratrol polysaccharide and a UV protection agent, where the trans-resveratrol polysaccharide is O-glycosidically linked with sugars, improving UV protection and texture by synergistically enhancing the sunscreen effect while reducing the amount of UV protection agents needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large amount of UV protection agent is mixed into cosmetics for use in sunscreen, then the UV protection effect is improved, but the skin feels sticky and the cosmetics are poorly spread
Solution Approach 1:
The patent combines trans-resveratrol polysaccharide with conventional UV protection agents (both inorganic scattering agents and organic absorbing agents) to create a composite sunscreen composition. This composite approach allows the trans-resveratrol polysaccharide to enhance UV protection while the polysaccharide component maintains spreadability and prevents stickiness, thus resolving the contradiction between UV protection effect and ease of application.
Solution Approach 2:
The patent changes the physical and chemical parameters of the UV protection system by introducing trans-resveratrol polysaccharide, which has different properties from conventional UV agents. The polysaccharide component provides water solubility and emulsification properties that improve spreadability, while the combined system achieves enhanced UV protection, thus resolving the contradiction through parameter optimization.
2Reliability
If a large amount of UV protection agent is mixed into cosmetics for use in sunscreen, then the UV protection effect is improved, but the skin is irritated
Solution Approach 1:
The patent creates a composite system where trans-resveratrol polysaccharide works synergistically with UV protection agents. The polysaccharide component has soothing and protective properties that reduce skin irritation caused by high concentrations of UV agents, while maintaining enhanced UV protection effect, thus resolving the contradiction between UV protection and skin comfort.
Solution Approach 2:
The trans-resveratrol polysaccharide acts as an intermediary substance that mediates between the UV protection agents and the skin. It provides a protective interface that reduces direct contact and potential irritation from UV agents while maintaining their protective function, thus resolving the contradiction between UV protection effect and skin irritation.
3Reliability
If resveratrol monosaccharide glycosides, such as piceid, are used in sunscreen cosmetic composition, then the UV protection effect is improved, but the water solubility is insufficient and mass production is impractical
Solution Approach 1:
The patent fundamentally changes the solubility parameter by using trans-resveratrol polysaccharide instead of monosaccharide glycosides. The polysaccharide structure with multiple sugar units provides extensive hydroxyl groups that form hydrogen bonds with water, achieving high water solubility and enabling mass production while maintaining UV protection effect.
Solution Approach 2:
The patent uses trans-resveratrol polysaccharide as a composite material that combines the UV-protective properties of resveratrol with the water solubility and processability of polysaccharides. This composite structure overcomes the solubility limitations of monosaccharide glycosides while maintaining or enhancing UV protection, making mass production practical.
