Oral CBD Composition Using BCP for Stability and Precise Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral cannabinoid therapies, particularly those containing cannabidiol (CBD), face challenges such as variable potency, instability during storage, and imprecise dosing due to the presence of impurities like THC, which complicates their use as pharmaceutical products.
Innovation Solution
A stable cannabidiol composition is developed, comprising synthetic CBD with high purity, beta-caryophyllene (BCP) as a solvent, and alpha tocopherol as an antioxidant, along with a mixture of C8 and C10 triglycerides, to maintain stability and reduce THC impurities below 1 ppm, ensuring consistent dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If CBD is administered orally in existing formulations, then ease of administration is improved, but stability and dosing precision deteriorate due to degradation and impurities
Solution Approach 1:
The patent extracts and removes degradation products (THC, CBN, quinone, CBDO) and impurities from the CBD composition through purification processes, achieving THC levels below 1000 ppm and preferably below 100 ppm. This extraction of harmful components resolves the contradiction by maintaining oral ease of administration while eliminating stability and dosing precision issues caused by degradation products.
Solution Approach 2:
The patent changes the chemical and physical parameters of the CBD composition by establishing specific concentration ranges for CBD (1-35% w/w), antioxidants (0.1-5% w/w), and solvents, along with controlling storage conditions (temperature, light exposure, humidity). These parameter changes maintain formulation stability during storage while preserving oral administrability, thus resolving the contradiction between ease of administration and reliability.
2Duration of action of stationary object
If CBD compositions are stored over time, then duration of action is extended, but potency and effectiveness deteriorate due to conversion to degradation products
Solution Approach 1:
The patent applies preliminary action by adding antioxidants (such as vitamin E, vitamin C, or BHT) to the CBD composition before storage, and by purifying the CBD to remove precursors of degradation products. This preliminary protection prevents degradation during storage, allowing extended storage duration while maintaining potency and effectiveness.
Solution Approach 2:
The patent controls storage parameters including temperature (refrigerated or frozen conditions), light exposure (protected from light), and humidity to prevent degradation. By optimizing these parameters, the composition maintains stability over extended storage periods, resolving the contradiction between storage duration and potency retention.
3Object-affected harmful factors
If THC levels are reduced to below 1000 ppm, then safety and dosing precision are improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs extraction and purification techniques such as chromatography, filtration, or crystallization to remove THC and other degradation products from the CBD composition. By systematically extracting harmful impurities to achieve THC levels below 1000 ppm (preferably below 100 ppm), the patent improves safety and dosing precision while managing manufacturing complexity through established purification protocols.
Solution Approach 2:
The patent controls manufacturing parameters including synthesis conditions, purification thresholds, and final formulation specifications to ensure THC levels remain below 1000 ppm. By establishing clear parameter targets and using standardized purification processes, the patent achieves high safety standards without excessive manufacturing complexity.
