Thermoformed Triterpene Extrudates for Solubility and Bioavailability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current formulations of triterpenes and triterpenoids suffer from low solubility, dispersion, and bioavailability due to their poor solubility and dispersibility in aqueous solutions, leading to low bioaccessibility and cumbersome manufacturing processes.
Innovation Solution
A composition comprising triterpenes/triterpenoids in the form of a thermoformed extrudate with a first amorphous phase and optionally a second crystalline phase, dispersed in natural or synthetic proteins, oligosaccharides, or polysaccharides, produced through hot extrusion, enhancing solubility and dispersion in aqueous media.

Engineering Contradiction Analysis
1Reliability
If conventional cosmetics containing hydroquinone, mercury, or high concentrations of vitamin C are used to treat melasma, then skin lightening effect is achieved, but skin irritation and safety issues occur
Solution Approach 1:
The patent extracts and eliminates harmful substances (hydroquinone, mercury, high concentration vitamin C) from conventional melasma treatments, replacing them with safe triterpene derivatives that provide effective skin lightening without causing irritation or safety concerns
Solution Approach 2:
The patent changes the chemical parameters by using specific concentrations of triterpene derivatives (0.01-10% w/w) and their combinations, achieving both safety and efficacy by optimizing the concentration parameters away from harmful thresholds while maintaining therapeutic effect
2Reliability
If natural plant extracts are used to treat melasma, then safety is improved, but treatment efficacy is insufficient
Solution Approach 1:
The patent creates composite formulations combining multiple triterpene derivatives from different natural sources (oleanolic acid, ursolic acid, betulinic acid, maslinic acid) with synergistic effects, achieving enhanced treatment efficacy while maintaining the safety profile of natural extracts
Solution Approach 2:
The patent merges multiple triterpene compounds with different mechanisms of action into a single formulation, combining their individual benefits to achieve superior overall efficacy in treating melasma while preserving safety
3Productivity
If topical treatments are applied frequently to achieve better melasma results, then treatment efficacy improves, but skin barrier function deteriorates
Solution Approach 1:
The patent uses triterpene derivatives that act rapidly and effectively at lower concentrations, allowing for less frequent application compared to conventional treatments, thereby reducing cumulative irritation while maintaining treatment efficacy through optimized formulation
