Sheet Cosmetic With CO2 and TRPM8 Agonist for Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body cosmetics that utilize carbon dioxide gas and TRPV3 or TRPV4 agonists for promoting blood circulation are inconvenient and have limited duration of effect, requiring specific conditions and not providing sufficient relief for fatigue, weariness, swelling, and pain.
Innovation Solution
A sheet-shaped body cosmetic combining carbon dioxide gas, a TRPM8 agonist such as menthol, and an ester oil, which can be applied conveniently and maintains blood circulation promotion for an extended period without the need for specific conditions, offering a tingling and penetration sensation with reduced skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carbon dioxide gas is used at high concentration (60 ppm or more) to promote blood circulation, then the effect of improving swelling is enhanced, but the requirement for high hydrostatic pressure and prolonged application time (5 minutes or more) increases
Solution Approach 1:
The patent changes the concentration parameter of carbon dioxide gas to a specific range (100-20,000 ppm) that achieves effective blood circulation promotion without requiring high hydrostatic pressure or prolonged application time, thus resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The patent combines carbon dioxide gas with TRPM8 agonists and ester oils to create a composite cosmetic formulation that enhances the blood circulation effect while reducing the need for specific application conditions, making the product more convenient to use
2Ease of operation
If carbon dioxide gas is used to promote skin blood circulation without water pressure, then the application becomes more convenient, but the duration of effect is limited (3 to 5 minutes)
Solution Approach 1:
The patent uses TRPM8 agonists that provide continuous cooling sensation and sustained blood circulation promotion, extending the duration of effect beyond the limited 3-5 minutes achieved by carbon dioxide gas alone, while maintaining application convenience
Solution Approach 2:
The combination of carbon dioxide gas with TRPM8 agonists and ester oils creates a synergistic effect that prolongs the blood circulation promotion duration while keeping the application method convenient and simple
3Reliability
If TRPV3 or TRPV4 agonists are used to promote blood circulation, then the effect is achieved, but the formulation requires specific conditions and has limited versatility
Solution Approach 1:
The patent employs TRPM8 agonists that are effective across various application scenarios and body parts, providing universal blood circulation promotion without requiring specific conditions, thus enhancing adaptability and versatility while maintaining reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combination of carbon dioxide gas, a TRPM8 agonist, and ester oil in the body cosmetic provides an immediate and long-lasting effect in promoting blood circulation, alleviating fatigue, weariness, swelling, and pain, with a comfortable sensation and low skin irritation, even at lower carbon dioxide concentrations, making it suitable for various applications.
Implementation Method 1
carbon dioxide gas which vasodilates in a condition of high hydrostatic pressure
Implementation Method 2
a TRPM8 agonist being one or more selected from the group consisting of menthol, menthyl lactate, trimethyl isopropyl butanamide, and menthoxypropanediol
