Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial sebum films are prone to oxidation, decomposition, and poor stability, especially in polluted environments, leading to inadequate skin protection due to changes in composition and barrier capacity.
Innovation Solution
An artificial sebum film composition comprising 78.4%-2% triglyceride, 1%-15% wax and ester, 20%-35% squalane, 0.1%-7% free fatty acid, 0.1%-6% phospholipid, 0.1%-10% cholesterol ester, 0.1%-10% cholesterol, 0.1%-10% antioxidant, and 0.1%-5% cellular activity regulator, with Taiwan camellia seed oil as an antioxidant and adenosine triphosphate for enhanced stability and skin penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional artificial sebum film composition is used, then basic skin barrier function is provided, but oxidation resistance and long-term stability are poor
Solution Approach 1:
The patent uses a composite material system comprising squalane (20-35%), triglyceride (2-78.4%), wax and ester (1-15%), free fatty acid (0.1-7%), phospholipid (0.1-6%), cholesterol ester (0.1-10%), cholesterol (0.1-10%), and antioxidant (0.1-10%). This multi-component composite structure provides both basic barrier function and enhanced oxidation resistance, resolving the contradiction between reliability and composition stability.
Solution Approach 2:
The patent optimizes the concentration parameters of each component to achieve improved stability. Specifically, squalane is maintained at 20-35% to provide stability while triglyceride is controlled at 2-78.4% to balance barrier function with oxidation resistance. The antioxidant content is set at 0.1-10% to prevent decomposition without compromising the basic sebum film properties.
2Reliability
If high triglyceride content is used, then skin barrier capacity is improved, but oxidation and decomposition increase
Solution Approach 1:
The patent introduces antioxidant (0.1-10%) as an intermediary substance that mediates between triglyceride and oxygen, preventing oxidation reactions. The antioxidant acts as a protective layer that allows high triglyceride content (2-78.4%) to maintain barrier capacity while preventing the generation of harmful oxidation products and free fatty acid decomposition.
3Reliability
If existing sebum composition is used, then basic moisturization is achieved, but protection against polluted environments is insufficient
Solution Approach 1:
The patent enhances specific local properties of the sebum film by incorporating squalane (20-35%) which provides superior environmental protection and pollutant resistance at the skin surface interface. The phospholipid (0.1-6%) and cholesterol (0.1-10%) components are strategically included to strengthen the film's resistance to UV light and suspended particles in polluted environments, while maintaining basic moisturization functions.

AI summary
A method for producing an artificial sebum film is provided with in raw material component and relative ratio, 78.4%-2% of triglyceride, 1%-15% of wax and ester, 20%-35% of squalane, 0.1%-7% of free fatty acid, 0.1%-6% of phospholipid, 0.1%-10% of cholesterol ester, 0.1%-10% of cholesterol, 0.1%-10% of antioxidant and 0.1%-5% of cellular activity regulator. The invention modifies the proportion of raw material composition of the artificial sebum film to reduce the negative effect generated by oxidation, and increase the proportion of squalane, so that the skin under high pollution can restore to the normal equilibrium state. Further, antioxidants and cellular active regulators are added to prolong the oxidation time of artificial sebum film and replenish the adenosine triphosphate in the cells.
