Fd-3m Liquid-Crystal Composition for Stable Oil and Water Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid-crystal compositions containing Fd-3m structures are limited in compositional flexibility and often destabilized by the inclusion of oil or water-soluble components, lacking biocompatibility and effective delivery performance for such components.
Innovation Solution
A liquid-crystal composition is formulated by blending a surfactant capable of forming hexagonal or pre-hexagonal structural bodies with water, incorporating an oil agent that does not convert these structures into lamellar bodies, and maintaining a specific ratio of surfactant to water, allowing for the formation of Fd-3m liquid crystals through a simple method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Fd-3m liquid crystal compositions are used, then thermodynamic stability is achieved, but compositional flexibility and ability to incorporate water-soluble components are limited
Solution Approach 1:
The invention changes the chemical parameters of the liquid crystal composition by incorporating water-soluble components and adjusting the surfactant-to-water ratio, while maintaining the Fd-3m structural parameter that ensures thermodynamic stability. This allows expanded compositional flexibility without sacrificing stability.
Solution Approach 2:
The invention creates a composite liquid crystal system combining surfactants, water, and water-soluble components (such as cosmetics, foods, inks, or agrochemicals) within the Fd-3m structure, achieving both compositional versatility and thermodynamic stability through the synergistic combination of multiple materials.
2Quantity of substance
If oil agents are added to Fd-3m liquid crystals, then oily component containment is improved, but the Fd-3m structure is often destroyed
Solution Approach 1:
The invention adjusts the surfactant concentration and water-to-surfactant ratio parameters to accommodate oil agents while maintaining the Fd-3m structural parameters, preventing structure destruction while enabling oily component containment.
Solution Approach 2:
The surfactant acts as an intermediary substance that mediates between the hydrophobic oil agents and the hydrophilic water phase, allowing oil containment within the Fd-3m structure without destroying the liquid crystal phase integrity.
3Adaptability or versatility
If biocompatibility is required, then application scope is expanded, but conventional compound selections are limited
Solution Approach 1:
The Fd-3m liquid crystal composition serves as a universal platform that can accommodate multiple biocompatible applications (cosmetics, foods, inks, agrochemicals) using the same structural framework, expanding application scope while maintaining ease of manufacture through standardized preparation methods.
