Beeswax Lipid Shell Resists Mechanical Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pharmaceutical and food formulations face challenges in maintaining the controlled release profile of active ingredients due to mechanical stress during manufacturing and consumption, leading to undesired changes in the release profile of sensitive compounds.
Innovation Solution
A lipid composition comprising 40% to 99.9% beeswax and up to 10% lipophilic surfactants, such as polyethoxylated fatty acids and sorbitan esters, which provides a protective shell that maintains the stability of the release profile even under mechanical stress, allowing for controlled release of active ingredients in pharmaceutical, veterinary, and food applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encapsulation techniques are used to protect active ingredients and control release, then stability and controlled release are improved, but mechanical stress during manufacturing alters the release profile
Solution Approach 1:
The patent modifies the chemical composition parameters of the encapsulating shell by incorporating specific surfactants (Tween 80, Span 85) in defined ratios with beeswax. This compositional parameter change enhances the shell's mechanical properties to resist manufacturing stress while maintaining controlled release characteristics.
Solution Approach 2:
The invention creates a composite encapsulating material combining beeswax (providing structural integrity) with lipophilic surfactants (providing mechanical flexibility and stress resistance). This composite structure maintains the protective function while withstanding mechanical stress during manufacturing processes like capsule filling and compression.
2Productivity
If mechanical stress is applied during manufacturing processes, then formulation scalability is improved, but the protective shell is denatured and release profile is accelerated
Solution Approach 1:
The encapsulating shell is pre-formulated with stress-resistant components (surfactants at 5-50% concentration) that provide mechanical cushioning before manufacturing processes begin. This beforehand reinforcement prevents shell denaturation during subsequent mechanical stress events in manufacturing, maintaining release profile integrity while enabling scalable production.
3Strength
If lipophilic surfactants are added to the lipid composition, then resistance to mechanical stress is improved, but formulation complexity increases
Solution Approach 1:
The selected surfactants (Tween 80, Span 85) serve multiple functions simultaneously: they provide mechanical stress resistance, maintain encapsulation integrity, control release kinetics, and ensure manufacturability. This multi-functionality reduces overall formulation complexity despite adding ingredients, as single components address multiple requirements.
