Solution Overview

Problem

Current Cannabis plant extract preparations face challenges in stabilizing cannabinoids and oleoresins in aqueous form at high concentrations, relying on carrier oils or starches rather than aqueous solutions, which limits bioavailability and stability.

Innovation Solution

A colloidal suspension method is developed by combining cannabinoids or oleoresins with an emulsifying/stabilizing agent and an acidic aqueous solution of pH less than 7.0, agitated to create a stable mixture that can be used in various forms, including beverages, topicals, and pharmaceuticals, utilizing fruit or vegetable juices as carriers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If carrier oils or starches are used to prepare Cannabis plant extracts, then the extracts can be stabilized and delivered, but the bioavailability is limited and the preparation complexity increases

Engineering Contradiction:
Improvestability of Cannabis extractsVSAvoidpreparation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an emulsifying agent as an intermediary substance that mediates between the hydrophobic Cannabis extracts and the hydrophilic aqueous solution. This emulsifier forms a stable interface, allowing the extracts to be suspended and stabilized in water-based carriers without requiring complex oil-based preparation systems

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the fundamental parameter of the carrier system from oil-based or starch-based to aqueous-based. By adjusting the pH to acidic conditions and using emulsifying agents, the patent transforms the solubility characteristics of Cannabis extracts, enabling them to stabilize in water-based solutions with improved bioavailability

Inventive Principle:
Principle #35Parameter changes

2Reliability

If Cannabis extracts are prepared in aqueous form, then the bioavailability improves, but the stability at high concentrations deteriorates

Engineering Contradiction:
Improvebioavailability of cannabinoidsVSAvoidstability of Cannabis extracts at high concentrations
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent creates a composite system combining aqueous solution, emulsifying agents, and Cannabis extracts. This composite formulation allows high concentrations of cannabinoids to remain stably suspended in water-based carriers, preventing phase separation while maintaining improved bioavailability characteristics

Inventive Principle:
