Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-emulsifying compositions containing ω3 polyunsaturated fatty acids (ω3 PUFA) face issues with ethanol and polyhydric alcohols causing capsule deformation, denaturation, and increased emulsifier content leading to gastrointestinal inflammation, while requiring high compliance and rapid absorption without meals.
Innovation Solution
A self-emulsifying composition with reduced ethanol and polyhydric alcohol content, utilizing 0.5-6% water and minimized emulsifiers, specifically polyoxyethylene sorbitan fatty acid esters and lecithin, to enhance compatibility and stability, allowing high ω3 PUFA content and rapid absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ethanol and polyhydric alcohols are added to improve dissolution and self-emulsifying properties, then the composition becomes more readily dispersible, but capsule deformation, cracks, and denaturation occur
Solution Approach 1:
The patent changes the chemical composition parameters by replacing ethanol and polyhydric alcohols with specific emulsifiers (polysorbate 20, polysorbate 80, lecithin) at optimized concentrations. This parameter change maintains self-emulsifying properties while eliminating capsule deformation and denaturation issues caused by the original alcohol-based system.
Solution Approach 2:
The patent extracts and removes the harmful components (ethanol and polyhydric alcohols) from the composition while retaining the essential self-emulsifying function through alternative emulsifiers. This extraction eliminates capsule deformation, cracks, and content denaturation while preserving the desired dispersibility.
2Stability of the object's composition
If emulsifier content is increased to improve self-emulsifying property, then the composition becomes more stable, but gastrointestinal inflammation risk increases
Solution Approach 1:
The patent optimizes the emulsifier content to specific ranges (polysorbate 20: 0.1-5%, polysorbate 80: 0.1-5%, lecithin: 0.1-5%) that provide sufficient emulsion stability while remaining below thresholds that cause gastrointestinal inflammation. This precise parameter control balances stability with safety.
Solution Approach 2:
The patent uses naturally occurring, biocompatible emulsifiers (lecithin from egg yolk or soybean, polysorbates) that are metabolized and excreted without accumulating to harmful levels in the gastrointestinal tract, thereby providing stable emulsification without long-term inflammatory risk.
3Quantity of substance
If ω3 PUFA content is increased to improve therapeutic effect, then the absorption efficiency decreases due to poor solubility
Solution Approach 1:
The patent introduces emulsifiers (polysorbate 20, polysorbate 80, lecithin) as intermediary substances that form micelles around ω3 PUFA molecules, enhancing their solubility and facilitating rapid absorption in the gastrointestinal tract. This intermediary mechanism allows high ω3 PUFA content to be delivered efficiently without the solubility limitations of pure oil formulations.
Solution Approach 2:
The patent creates a composite formulation combining ω3 PUFA with emulsifiers and oils in specific ratios, forming a self-emulsifying system that maintains high active ingredient content while ensuring rapid dissolution and absorption through the synergistic interaction of components.
4Adaptability or versatility
If the composition is made alcohol-free to improve patient compliance, then the dissolution capability deteriorates
Solution Approach 1:
The patent removes ethanol and polyhydric alcohols from the composition to improve patient compliance, particularly for alcohol-intolerant patients. The dissolution capability is then restored through the use of alternative emulsifiers that provide comparable or superior self-emulsifying properties without the harmful effects of alcohols.
Solution Approach 2:
The patent changes the solvent system from alcohol-based to emulsifier-based, maintaining the liquid or semi-liquid formulation characteristics necessary for dissolution while eliminating alcohol content to improve patient compliance and safety.

AI summary
A self-emulsifying composition which comprises, when taking the total amount of the self-emulsifying composition as 100mass%, 70 to 90mass% of at least one compound selected from the group consisting of ω3 polyunsaturated fatty acids, pharmaceutically acceptable salts thereof, and esters of the same, 0.5 to 6mass% of water and 1 to 29mass% of an emulsifying agent that comprises a polyoxyethylene sorbitan fatty acid ester (and that further contains a polyoxyl castor oil optionally, with the proviso that the emulsifying agent does not include lecithin) and which contains 3 to 40 parts by mass of lecithin relative to 100 parts by weight of the ω3 polyunsaturated fatty acid or the like. This self-emulsifying composition exhibits excellent self -emulsifying properties, composition dispersibility, emulsion stability and absorbability, and does not contain ethanol or a polyhydric alcohol or contains the same only in a low concentration. The self-emulsifying composition is useful for food and medicine.
