Clear Shampoo Composition Combining Cleansing and Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shampoos often strip hair of moisture and leave it over-processed and difficult to manage, while clear compositions are generally poor conditioners, failing to meet consumer desires for cleansing without unmanageable hair.
Innovation Solution
A personal care composition comprising an anionic ether sulfate and amphoteric surfactant system, combined with a cationic guar gum and polypropylene alkyl ether conditioning system, provides cleansing and conditioning benefits without compromising clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional shampoos are used to clean hair, then hair becomes clean, but hair becomes stripped of moisture and difficult to manage
Solution Approach 1:
The patent combines cleansing and conditioning functions into a single shampoo composition. The formulation integrates surfactants for cleaning with conditioning agents (including cationic polymers and oils) that deposit on hair to restore moisture and improve manageability, eliminating the need for separate conditioner application.
Solution Approach 2:
The shampoo uses a composite formulation containing multiple functional components: anionic surfactants for cleansing, cationic polymers for conditioning and anti-static effects, natural oils for moisture, and polymers for volume. This composite material approach allows simultaneous achievement of cleaning and conditioning benefits.
2Shape
If clear shampoo compositions are formulated, then product aesthetics are improved, but conditioning performance deteriorates
Solution Approach 1:
The patent achieves clarity by carefully controlling the physical and chemical parameters of the formulation, including pH, ionic strength, and surfactant concentration. By optimizing these parameters, the composition remains visually clear while still allowing conditioning agents to effectively deposit on hair.
Solution Approach 2:
The formulation uses specific surfactants and solubilizing agents as intermediaries that allow conditioning components to remain dispersed in a clear aqueous system. These intermediaries enable the conditioning agents to be delivered in a clear composition without causing cloudiness or precipitation.
