Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional THC delivery systems for water-based beverages suffer from inconsistent and slow cannabinoid uptake, leading to unpredictable bloodstream concentrations and delayed effects, making it difficult for consumers to control their THC intake effectively.
Innovation Solution
A modified oil-in-water microemulsion system with a high-water content beverage, utilizing a phospholipid, polyethylene glycol derivative, oil, alcohol, and sugar or sugar alcohol, which forms stable and clear microemulsion droplets for rapid and reproducible delivery of cannabinoids to the bloodstream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If oil-soluble cannabinoids are directly added to water-based liquids, then the beverage can be formulated, but the cannabinoids dissociate from the water and adhere to container sides or are processed with other oils in the digestive tract, resulting in slow and variable uptake
Solution Approach 1:
The patent introduces an oil phase as an intermediary carrier that contains the oil-soluble cannabinoids. This oil phase is then emulsified in the water-based beverage, allowing the cannabinoids to remain solubilized and available for absorption rather than dissociating and adhering to container walls or being processed with dietary oils.
Solution Approach 2:
The patent changes the physical state and distribution parameters of the cannabinoids by creating an emulsion system. The cannabinoids are dispersed in fine oil droplets throughout the water-based beverage, transforming them from a state where they would settle or adhere to a state where they remain suspended and bioavailable.
2Quantity of substance
If conventional emulsion systems are used to deliver cannabinoids in water-based beverages, then solubility is improved, but the uptake rate remains slow and inconsistent, leading to unpredictable bloodstream concentrations
Solution Approach 1:
The patent optimizes emulsion parameters including droplet size distribution, oil phase composition, and surfactant selection to create an emulsion that facilitates rapid absorption. The specific parameter changes include using a refined oil phase with controlled composition and adjusting the emulsion to achieve optimal droplet sizes for rapid gastrointestinal absorption.
Solution Approach 2:
The patent creates a composite delivery system combining multiple components: oil phase, water-based beverage, and emulsifying agents. This composite structure allows the cannabinoids to be delivered in a form that maintains solubility while enabling rapid and consistent absorption into the bloodstream.
3Quantity of substance
If high oil content is used to solubilize cannabinoids in water-based beverages, then solubility is achieved, but the beverage becomes less appealing and the oil is processed more slowly in the digestive tract
Solution Approach 1:
The patent dramatically reduces the oil content parameter while maintaining cannabinoid solubility through efficient emulsification. By changing the emulsion parameters and using refined oil phases, the system achieves adequate solubility with minimal oil content, resulting in a more appealing beverage that is also processed more rapidly in the digestive tract.
Solution Approach 2:
The patent creates a fine emulsion structure with small oil droplets dispersed throughout the water-based beverage. This porous-like distribution allows adequate solubilization of cannabinoids while maintaining low overall oil content and rapid digestive processing.
4Quantity of substance
If cannabinoids are delivered in oil-based systems, then solubility is maintained, but the onset of effect is delayed by 30-60 minutes and peak bloodstream concentration occurs 1.5-3 hours after consumption
Solution Approach 1:
The patent changes the delivery system parameters from pure oil-based to a water-based emulsion system. This parameter change enables the cannabinoids to be delivered in a form that is both stable and rapidly absorbable, reducing onset time to approximately 15-30 minutes and achieving peak bloodstream concentration within 30-60 minutes, similar to alcohol-based beverages.

AI summary
Microemulsion beverages are described where hydrophobic liquid droplets are distributed in a continuous hydrophilic liquid phase. The described microemulsion beverages may be thought of as modified oil-in-water (MOIHW) microemulsions, where both the “oil” and “water” phases of the microemulsion are modified. The oil phase droplets of the MOIHW microemulsion are modified with alcohol and can solubilize oil-soluble species, including cannabis extracts. The polar continuous “water” phase of the MOIHW microemulsion is modified with a sugar or sugar alcohol.
