Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medicinal ingredients like glycyrrhetinic acid and tocopherol in oral compositions have low solubility and stability issues, limiting their effectiveness and regulatory compliance due to potential foreign taste and restricted usage, necessitating enhanced adsorption performance on gums and oral mucosa.
Innovation Solution
An oral composition comprising specific amounts of higher alcohols, surfactants, and water, forming an α-gel structure to increase the adsorption of oil-soluble medicinal ingredients such as glycyrrhetinic acid and tocopherol, ensuring effective embedding and prolonged action while adhering to regulatory limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the amount of oil-soluble medicinal ingredients (glycyrrhetinic acid, tocopherol) is increased to enhance medicinal effects, then the pharmacological effectiveness is improved, but foreign taste occurs and regulatory compliance deteriorates
Solution Approach 1:
The patent uses higher alcohols (12-22 carbon atoms) and surfactants as intermediary substances to form an α-gel structure that mediates between the oil-soluble medicinal ingredients and the aqueous environment. This gel structure allows effective delivery of medicinal ingredients without requiring excessive amounts that would cause foreign taste, thus resolving the contradiction between pharmacological effectiveness and sensory acceptability.
Solution Approach 2:
The patent changes the physical state and organizational structure of the formulation by forming an α-gel phase with specific molecular arrangement. This parameter change in the system's physical state allows for controlled release and reduced irritation while maintaining effective medicinal ingredient concentrations within regulatory limits.
2Reliability
If the amount of oil-soluble medicinal ingredients is increased to overcome low solubility, then the medicinal effect is enhanced, but storage stability deteriorates
Solution Approach 1:
The patent creates a composite system consisting of higher alcohols, surfactants, and oil-soluble medicinal ingredients organized in an α-gel structure. This composite material approach allows the incorporation of oil-soluble medicinal ingredients with maintained solubility and improved storage stability, as the gel matrix provides a stable environment that prevents precipitation and degradation.
3Stability of the object's composition
If conventional surfactants and oil agents are used to improve solubility of medicinal ingredients, then dispersibility is enhanced, but the medicinal ingredient adsorption to gums and oral mucosa is insufficient
Solution Approach 1:
The patent applies local quality by creating a specific α-gel structure with particular molecular arrangement and properties in the formulation. This localized structural organization provides both good dispersibility and enhanced adsorption performance to gums and oral mucosa, as the gel structure facilitates close contact and binding at the application site while maintaining overall formulation stability.
Applied Scientific Principles
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 effectively enhances the adsorption of medicinal ingredients to the gums and oral mucosa, improving their pharmacological effects and stability, thus overcoming solubility and regulatory constraints.
Implementation Method 1
when an oral composition comprises specific higher alcohol and surfactant in specific amounts, respectively, in addition to an oil-soluble medicinal ingredient, such as glycyrrhetinic acid, and water such that the content of oil agent other than the oil-soluble medicinal ingredient, higher alcohol, and flavoring agent is restricted with respect to the content of the higher alcohol and that the content of an abrasive powder comprising a polyvalent metal is restricted, the amount of the oil-soluble medicinal ingredient adsorbed to the gums and oral mucosa can be effectively increased
Implementation Method 2
the amount of the oil-soluble medicinal ingredient adsorbed to the gums and oral mucosa can be effectively increased
