Natural Soap Cleanser Gel With pH Control and Low Residue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formulating a cleanser that uses natural soaps, such as fatty acid salts, without causing skin irritation and maintaining a suitable viscosity and rinsability is challenging due to the basic pH and compatibility issues with conventional additives, and the tendency to leave a film on the skin.
Innovation Solution
A cleanser formulation that includes a fatty acid salt as the primary cleansing agent, a moisturizer, and a viscosity modifier like xanthan gum to maintain a pH between 6 and 11, ensuring a gel-like consistency and effective skin compatibility, while minimizing skin irritation and film residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If natural soaps (fatty acid salts) are used as the primary cleansing agent, then the cleanser is more natural and skin-friendly, but the cleanser tends to leave a film on the skin and has basic pH that causes skin irritation
Solution Approach 1:
The patent introduces a chelating agent as an intermediary substance that binds to calcium and magnesium ions in hard water, preventing them from reacting with the fatty acid salts to form insoluble salts. This mediator approach eliminates the film residue issue while maintaining the natural soap's skin-friendly properties
Solution Approach 2:
The patent adjusts the pH parameter by incorporating acidic ingredients (citric acid, lactic acid, malic acid) to neutralize the basic pH of the fatty acid salts, bringing it into a skin-compatible range. This parameter change reduces skin irritation while preserving the natural cleansing properties
2Object-affected harmful factors
If natural soaps are used without non-naturally derived detergents, then the formulation is more natural, but achieving adequate cleansing performance becomes difficult
Solution Approach 1:
The patent creates a composite cleansing system combining fatty acid salts with complementary natural ingredients including chelating agents, acidic modifiers, and water-soluble polymers. This composite approach enhances the cleansing performance of natural soaps without requiring synthetic detergents, achieving both effectiveness and skin compatibility
3Ease of manufacture
If conventional additives are used with natural soaps, then the cleanser achieves adequate formulation, but the basic pH creates compatibility issues with many additives
Solution Approach 1:
The patent systematically adjusts the pH parameter by adding acidic components to counterbalance the basic pH of fatty acid salts. This parameter modification creates a chemically stable environment that is compatible with a broader range of additives, including thickeners, fragrances, and moisturizing agents, thereby improving formulation flexibility
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 formulation achieves a suitable viscosity, feel, and rinsability without skin sensitivity, using a high percentage of natural ingredients and maintaining a pH that enhances the performance of additives, reducing skin irritation and film perception.
