Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin and hair cleansing agents lack adequate foaming power, foam quality, and leave a sticky residue while failing to provide a moist feeling after use.
Innovation Solution
Incorporating a hydroxystearic acid polymer into the cleansing agent, combined with ionic surfactants and polyvalent alcohols, to enhance foaming power, foam quality, and rinsing ease, while preventing stickiness and achieving a moist feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If fatty acid soaps and amino acid-based surfactants are used for main ingredients, then foaming power is superior, but foam quality and moist feeling after rinsing are inadequate
Solution Approach 1:
The patent combines multiple surfactant types (fatty acid soaps, amino acid-based surfactants, and hydroxystearic acid polymers) to create a composite cleansing agent system. This composite approach allows the formulation to achieve both superior foaming power from the surfactants and improved foam quality along with moist feeling from the hydroxystearic acid polymer components, resolving the contradiction between power and reliability.
Solution Approach 2:
The patent introduces hydroxystearic acid polymer with specific molecular weight and hydroxyl value parameters to modify the cleansing agent's properties. By controlling the polymer's molecular weight (100-10000 Da) and hydroxyl value (10-50 mg KOH/g), the formulation achieves optimal balance between foaming power, foam quality, and post-rinsing moist feeling, transforming the performance parameters of the cleansing agent.
2Reliability
If cleansing agents are formulated to provide superior cleansing strength and feel during use, then cleansing effectiveness is improved, but foaming power, foam quality and moist feeling after cleansing become inadequate
Solution Approach 1:
The patent employs a composite formulation incorporating fatty acid soaps for cleansing strength, amino acid-based surfactants for gentle cleansing, and hydroxystearic acid polymer for foam quality and moist feeling. This multi-component composite system ensures that cleansing effectiveness, foaming power, and post-rinsing comfort are all achieved simultaneously without compromising any single attribute.
Solution Approach 2:
The hydroxystearic acid polymer serves multiple functions simultaneously: it enhances foam quality, provides moist feeling after rinsing, and contributes to cleansing effectiveness. This multi-functional component allows the cleansing agent to achieve superior performance across multiple parameters without requiring separate additives for each function, thereby maintaining foaming power while improving overall cleansing quality.
3Stability of the object's composition
If hydroxystearic acid polymer is incorporated to improve wettability and water holding properties, then cosmetic stability is enhanced, but foaming power and foam quality in cleansing agents remain undeveloped
Solution Approach 1:
The patent optimizes the hydroxystearic acid polymer's parameters (molecular weight 100-10000 Da, hydroxyl value 10-50 mg KOH/g) to achieve the right balance between cosmetic stability and foaming performance. By carefully controlling these parameters, the polymer provides sufficient water holding properties and emulsion stability while still allowing the formulation to achieve superior foaming power and foam quality when combined with appropriate surfactants.
