Shampoo Gel Network Balances Conditioning and Lather
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shampoos often leave hair in a wet, tangled, and unmanageable state after cleaning, and fail to provide satisfactory smooth feel and conditioning benefits while maintaining adequate cleansing and lather profiles.
Innovation Solution
A shampoo composition incorporating a dispersed gel network phase with 5-8% fatty alcohols, 0.01-1.50% structurants or suspending agents, 0.5-1% cationic deposition polymer, and 5-50% anionic detersive surfactants, which forms a lamellar or vesicular solid crystalline phase for improved conditioning and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher levels of conditioning agents are included in the fatty alcohol gel network phase, then hair conditioning benefits are improved, but lathering of the shampoo formulation is impacted
Solution Approach 1:
The patent optimizes the concentration of conditioning agents within the gel network phase to achieve a balance between conditioning benefits and lathering capability. By carefully controlling the amount of conditioning agents incorporated into the gel structure, the formulation maintains adequate lather while delivering improved hair conditioning.
Solution Approach 2:
The invention creates a composite gel network phase combining fatty alcohols, conditioning agents, and surfactants in a structured matrix. This composite structure allows conditioning agents to be sequestered within the gel network, reducing their interference with lather formation while still providing hair conditioning benefits when the product is applied.
2Reliability
If higher gel network levels are used, then wet feel and dry conditioning benefit are improved, but product phase stability is rendered unstable
Solution Approach 1:
The patent optimizes the concentration of fatty alcohols within a specific range (5-8% of the total composition) to achieve the desired balance. This controlled parameter adjustment ensures that the gel network provides sufficient conditioning benefits while maintaining product phase stability and preventing excessive viscosity or separation.
3Reliability
If cationic polymers are used to form coacervate for conditioning benefits, then hair conditioning is improved, but smooth feel in dry hair is not satisfactory
Solution Approach 1:
The invention employs a composite gel network phase combining fatty alcohols with cationic polymers and other conditioning agents. This composite structure provides superior smooth feel in dry hair compared to conventional cationic polymer coacervates, while maintaining effective hair conditioning. The fatty alcohol matrix enhances the performance of the cationic components.
