Multi-phase shampoo composition with an aesthetic design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiphase shampoos face challenges in maintaining stable discrete phases during storage and use, which affects their cleansing and conditioning performance and aesthetic appeal, as charged ingredients like surfactants and polymers can interact, leading to diminished stability and rheology.
Innovation Solution
A multiphase shampoo composition with a cleansing phase containing detersive surfactants and a benefit phase with a gel network of fatty alcohol and secondary surfactants, which are physically discrete and stable, forming an aesthetic design within the container, using a cationic deposition polymer to maintain stability and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charged ingredients including surfactants and polymers are used to provide good conditioning, then conditioning performance is improved, but phase stability and rheology are diminished
Solution Approach 1:
The shampoo composition is divided into distinct functional phases: a cleansing phase containing detersive surfactants and a benefit phase containing conditioning polymers and fatty alcohols. This segmentation allows each phase to perform its specific function while maintaining overall composition stability, resolving the contradiction between conditioning performance and phase stability.
Solution Approach 2:
The invention uses composite material structures by combining incompatible charged ingredients (surfactants and polymers) into separate but physically mixed phases. The benefit phase acts as a composite containing both conditioning polymers and fatty alcohols, enabling stable coexistence of ingredients that would otherwise interact adversely, thus maintaining both conditioning performance and phase stability.
2Illumination intensity
If discrete phases are formed to provide visual appeal and signal quality, then aesthetic appearance is improved, but phase disruption becomes noticeable and indicates mediocre quality
Solution Approach 1:
The multiphase composition is designed to dynamically maintain phase separation under normal storage and handling conditions while allowing controlled interaction during use. The distinct phases remain visually separate and stable on the shelf, providing aesthetic appeal, but can be properly dispensed and mixed during shampooing, resolving the contradiction between visual appeal and phase stability.
