Concentrated Shampoo Conditioning Gel Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concentrated shampoo compositions fail to provide a conditioning benefit to hair without increasing viscosity or reducing the clean hair feel.
Innovation Solution
Incorporating high levels of short chain diols, such as 1,2 propylene glycol, and low viscosity oils like light mineral oil, along with a specific combination of anionic and cationic surfactants in the conditioning gel network, which maintains stability and integrity without affecting the cleansing phase's performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oil is added to concentrated shampoo composition, then conditioning benefit is provided, but viscosity increases
Solution Approach 1:
The patent changes the chemical parameters by introducing short chain diols (3-7 carbons) as a new component and adjusting the surfactant composition ratios. This modifies the interaction between oil and water phases, allowing oil dispersion without significant viscosity increase while maintaining conditioning benefits
Solution Approach 2:
The patent creates a composite system combining short chain diols, anionic surfactants, and cationic surfactants in specific ratios. This composite approach enables synergistic effects where the diol-surfactant combination disperses oil effectively without the viscosity penalty normally associated with oil addition
2Reliability
If oil is added to concentrated shampoo composition, then conditioning benefit is provided, but clean hair feel is reduced
Solution Approach 1:
The patent modifies the chemical composition parameters by using short chain diols with specific carbon lengths (3-7) and controlling oil content at 0.05-10% wt. These parameter changes ensure sufficient conditioning while preventing the heavy, greasy feel that typically results from oil addition
Solution Approach 2:
The patent applies local quality by using low viscosity oils (1-500 cPs) and controlling the distribution of oil throughout the composition via short chain diol mediation. This ensures conditioning benefits are localized where needed without creating overall heaviness or residue on hair
3Productivity
If concentration of shampoo is increased, then productivity is improved, but conditioning benefit is reduced
Solution Approach 1:
The patent develops a composite formulation where concentrated surfactant systems (27-70% wt) work synergistically with short chain diols and controlled oil additions. This composite structure maintains high concentration for productivity while incorporating conditioning components for hair care benefits
