Keratotic Plug Removal With pH-Controlled Basic Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing keratotic plugs cause skin irritation and pain, and are not effective in thoroughly removing keratotic plugs and associated dirt from pores, leading to pore clogging and skin dullness.
Innovation Solution
A composition containing 2-amino-2-hydroxymethyl-1,3-propanediol, 2-amino-2-methyl-1-propanol, and/or 2-amino-2-methyl-1,3-propanediol, with a pH of 8.5 to 12.5, which penetrates into keratotic plugs to elute lipids and proteins, facilitating their removal without causing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional oil agents or surfactants are used to remove keratotic plugs, then some keratotic plugs can be removed, but the removal is not thorough and pore clogging persists
Solution Approach 1:
The patent changes the pH parameter of the composition to a basic range (pH 8.5-12.5), which fundamentally alters the chemical environment for keratotic plug removal. This pH change enables the composition to effectively dissolve both lipid-based and protein-based keratotic plugs, achieving thorough removal that conventional neutral or acidic surfactants cannot accomplish.
Solution Approach 2:
The patent employs a composite formulation combining basic substances (such as amino acids, hydroxides, or carbonates) with surfactants and other cosmetic ingredients. This composite approach creates a synergistic effect where the basic substance dissolves keratotic plugs while the surfactant provides cleansing and foaming properties, resulting in comprehensive pore cleaning.
2Manufacturing precision
If strong chemical agents are used to thoroughly remove keratotic plugs, then removal effectiveness improves, but skin irritation and pain increase
Solution Approach 1:
The patent carefully controls the pH parameter within the range of 8.5-12.5, which is basic enough to effectively dissolve keratotic plugs but not so extreme as to cause severe skin irritation. This optimized pH range achieves effective removal while maintaining skin compatibility.
Solution Approach 2:
The patent uses mild basic substances such as amino acids (lysine, arginine, histidine) as intermediaries that can dissolve keratotic plugs through chemical reaction while being inherently gentle on the skin. These amino acid-based bases act as mediators between the need for effective removal and the need for skin safety.
3Manufacturing precision
If physical removal methods are used to extract keratotic plugs, then visible plugs can be removed, but skin damage and irritation occur
Solution Approach 1:
The patent replaces mechanical/physical removal methods with a chemical dissolution mechanism. The basic substances in the composition chemically dissolve keratotic plugs through saponification of lipids and dissolution of proteins, eliminating the need for physical extraction that causes skin damage.
Solution Approach 2:
The patent employs chemical intermediaries (basic substances and surfactants) that facilitate the removal of keratotic plugs through chemical interaction rather than physical force. These intermediaries penetrate into pores and dissolve plugs in situ, avoiding the trauma of physical extraction methods.
Applied Scientific Principles
