Hydrogel Soap Composition Neutral pH Formability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soaps often cause skin irritation due to high alkalinity and lack of moisturizing properties, and hydrogel soaps suffer from softness, stickiness, and inadequate detergency, necessitating a novel composition with neutral pH, superior formability, and reduced humectant usage.
Innovation Solution
A hydrogel soap composition comprising 1-10% gelling agent, 5-35% surfactant, 2-30% humectant, 0.05-2% curing agent, and 30-80% purified water, prepared by heating and stirring the mixture with added surfactant, resulting in a pH range of 5.0-7.0 and viscosity of 1,800-9,500 cps, enhancing detergency and moisturizing power while minimizing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional soaps with high alkalinity (pH 8.0) are used to achieve strong detergency, then cleaning power is improved, but skin irritation occurs and moisturizing properties deteriorate
Solution Approach 1:
The patent changes the pH parameter from conventional alkaline (pH 8.0) to neutral or weakly acidic (pH 5.0-7.0) by selecting specific surfactants and adjusting the composition ratio, thereby reducing skin irritation while maintaining detergency through optimized surfactant selection
Solution Approach 2:
The patent creates a composite soap formulation combining multiple surfactants (anionic, nonionic, amphoteric types) with humectants and gelling agents to achieve both strong detergency and skin friendliness, where the synergistic interaction of components resolves the contradiction between cleaning power and skin compatibility
2Object-affected harmful factors
If liquid facial cleansers are used to reduce skin irritation, then skin compatibility is improved, but manufacturing cost increases due to additional storage containers
Solution Approach 1:
The patent changes the physical state parameter from liquid to semi-solid gel by incorporating gelling agents and optimizing surfactant concentration, enabling the product to be packaged without additional storage containers while maintaining the skin-friendly properties of liquid cleansers
Solution Approach 2:
The hydrogel soap formulation serves multiple functions: it provides detergency, moisturizing effects, and self-contained packaging in a single semi-solid product, eliminating the need for separate storage containers required by liquid cleansers
3Object-affected harmful factors
If hydrogel soap with high humectant content is used to improve moisturizing power, then skin hydration is improved, but the soap becomes overly soft and loses formability
Solution Approach 1:
The patent optimizes the humectant content parameter within a specific range (2-30% by weight) and balances it with surfactant and gelling agent concentrations to achieve both moisturizing power and structural integrity, preventing excessive softness while maintaining skin hydration
Solution Approach 2:
The patent creates a composite formulation where humectants work synergistically with surfactants and gelling agents, allowing the system to maintain both moisturizing properties and formability through the balanced interaction of multiple components
4Shape
If jelly soap based on gelatin is used to achieve gel structure, then formability is improved, but the soap becomes sticky when exposed to water and requires excessive rinsing
Solution Approach 1:
The patent changes the chemical composition parameter by replacing gelatin-based gelling agents with alternative gelling systems that do not exhibit excessive stickiness when wet, while maintaining the desired gel structure and formability through optimized composition ratios
Solution Approach 2:
The patent selects gelling agents and surfactant combinations that provide sufficient formability for the product's functional life without requiring excessive rinsing, optimizing the balance between shape retention and ease of removal

AI summary
Composition of a hydrogel soap, a hydrogel soap, and a method of preparing the same. The hydrogel soap represents detergency or moisturizing power superior to that of a general soap and has weak acidity or neutral-pH (pH 5.0 to pH 7.0), so that the skin irritation is mitigated and superior formability is represented.
