Clear Cleansing Composition Discrete Particle Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clear cleansing compositions, such as shampoos, lack adequate conditioning benefits due to the opaque nature caused by large particle silicones or high levels of fatty amphiphiles, which are incompatible with other materials.
Innovation Solution
A clear cleansing composition comprising a detersive surfactant, an aqueous carrier, and discrete particles made of anhydrous particles swollen in an aqueous phase. These discrete particles include a combination of fatty amphiphiles and secondary surfactants, with a size range of 200 microns to 15,000 microns, allowing for high transmittance of 75% or more.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large particle silicones or high levels of fatty amphiphile are used as dispersed phase gel network, then conditioning benefits are provided, but the composition becomes opaque
Solution Approach 1:
The patent changes the physical and chemical parameters of the conditioning agents by converting them into discrete particles with specific size ranges (0.2-1500 micrometers). This particle formation allows the conditioning agents to be incorporated into clear cleansing compositions without causing opacity, as the discrete particle structure modifies how light interacts with the conditioning phase compared to conventional dispersed gel networks
Solution Approach 2:
The invention creates a composite structure where discrete particles containing conditioning agents (fatty amphiphiles, silicones, or their combinations) are suspended in a clear continuous phase. This composite approach allows both the clearing agents and conditioning agents to coexist in a transparent formulation, resolving the contradiction between transparency and conditioning benefits
2Reliability
If conventional dispersed phase gel network is used with high levels of fatty amphiphile, then conditioning benefits are achieved, but the composition becomes incompatible with other materials
Solution Approach 1:
The patent transforms the physical state and distribution parameters of fatty amphiphiles by incorporating them into discrete particles. This particle encapsulation allows higher levels of fatty amphiphile (0.5-30% by weight) to be included in the composition without causing incompatibility issues, as the particle structure isolates and stabilizes these agents within the clear continuous phase
Solution Approach 2:
The discrete particle structure acts as an intermediary vehicle that carries conditioning agents through the clear continuous phase. This particle mediator allows incompatible materials (fatty amphiphiles and clearing agents) to coexist by providing a separate phase that prevents direct interaction while still delivering conditioning benefits to the hair
3Illumination intensity
If clear appearance is prioritized in cleansing composition, then transparency is achieved, but conditioning benefits are insufficient
Solution Approach 1:
The invention creates a composite system where a clear continuous phase (providing transparency) contains suspended discrete particles (providing conditioning). This composite structure enables the formulation to simultaneously achieve both clear appearance and adequate conditioning benefits, as the discrete particles deliver conditioning agents without compromising the overall transparency of the composition
Solution Approach 2:
The patent applies local quality by concentrating conditioning agents within discrete particles distributed throughout the clear continuous phase. This localized concentration allows conditioning benefits to be delivered at specific points (where particles are present) while maintaining overall transparency, as the clear continuous phase dominates the optical properties of the composition

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves a clear appearance while providing conditioning benefits similar to conventional opaque shampoos, effectively addressing the need for clear cleansing products that offer conditioning without compromising clarity.
