Alkaline Skin Cleansing Composition for Keratotic Plug Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin cleansing compositions fail to effectively remove keratotic plugs without causing pain or irritation, and they do not adequately address pore clogging and skin roughness, leading to skin troubles like acne and rashes.
Innovation Solution
A skin cleansing composition containing 0.08-35 mass% of 2-amino-2-methyl-1-propanol with a pH of 9.3-12.5, which penetrates keratotic plugs, breaks down proteins and lipids, and softens the skin, effectively removing keratotic plugs while minimizing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleansing compositions (surfactants, oils, acids) are used to remove keratotic plugs, then some keratotic plugs can be removed, but the removal is insufficient and does not directly remove dirt in the pores
Solution Approach 1:
The patent changes the pH parameter to 9.3-12.5 (alkaline range) and uses 2-amino-2-methyl-1-propanol as the key ingredient, which fundamentally alters the mechanism of keratotic plug removal compared to conventional acidic or neutral formulations, enabling direct penetration and dissolution of pore dirt
Solution Approach 2:
The composition combines 2-amino-2-methyl-1-propanol with specific co-solvents (polyethylene glycol, propylene glycol, butylene glycol) and surfactants to create a composite formulation that enhances penetration ability while maintaining skin compatibility, achieving both effective removal and skin safety
2Reliability
If physical removal methods (sheet packs) are used to directly remove keratotic plugs, then pore clogging is significantly reduced, but skin pain and irritation occur
Solution Approach 1:
The patent replaces the mechanical physical removal method (sheet pack peeling) with a chemical dissolution mechanism using alkaline 2-amino-2-methyl-1-propanol, which chemically breaks down keratotic plugs without mechanical force, eliminating skin pain and irritation while maintaining effective removal
Solution Approach 2:
The patent introduces 2-amino-2-methyl-1-propanol as a chemical intermediary that mediates between the cleansing composition and keratotic plugs, enabling gentle chemical dissolution that avoids the harsh mechanical action of physical removal methods
3Ease of operation
If conventional cleansing compositions are used, then some cleaning effect is achieved, but skin roughness persists and pore clogging is not sufficiently prevented
Solution Approach 1:
The patent uses high pH (9.3-12.5) alkaline formulation with 2-amino-2-methyl-1-propanol that fundamentally changes the cleaning mechanism to effectively dissolve keratotic plugs and prevent pore clogging, while the alkaline nature also helps smooth skin roughness
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 composition achieves a significant reduction in pore clogging, prevents skin roughness, and leaves the skin feeling fine, soft, and bright, without causing pain or irritation during the removal process.
