Silicon-Based THC Derivatives for Stable Topical Films
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tetrahydrocannabinol (THC) has low stability in air, light, acid media, and high temperatures, and its topical formulations face challenges in forming thin films due to high surface tension, limiting their effectiveness and stability in medicinal and cosmetic applications.
Innovation Solution
Development of silicon-based THC derivatives with Si—O—Si bonds, which are bound to the THC molecule, enhancing stability and solubility, allowing for the formation of thin films and prolonged release of THC through slow hydrolysis, and facilitating incorporation into topical and dermatological products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pure tetrahydrocannabinol is used in topical formulations, then the formulation has simple composition, but the stability in air, light, acid media, and high temperature is low
Solution Approach 1:
The patent applies composite materials by combining THC with silicon-based compounds to form silicon-based THC derivatives. These derivatives integrate the therapeutic properties of THC with the stability and film-forming capabilities of silicones, creating a composite molecular structure that resolves the contradiction between simplicity and stability.
Solution Approach 2:
The patent changes the chemical parameters of THC by modifying its molecular structure through silicon-based functional groups. This structural modification alters key parameters such as stability, surface tension, and solubility, enabling the derivative to maintain THC's therapeutic effects while overcoming its inherent instability.
2Ease of manufacture
If pure tetrahydrocannabinol is used in topical formulations, then the formulation is easy to prepare, but the surface tension is high which limits thin film formation
Solution Approach 1:
The silicon-based functional groups attached to THC molecules fundamentally change the surface tension parameter of the formulation. The silicones' inherent low surface tension property transfers to the derivative, enabling thin film formation while maintaining ease of formulation preparation through conventional silicone processing methods.
3Reliability
If silicon-based THC derivatives are used to improve stability and solubility, then the therapeutic effectiveness is enhanced, but the molecular structure complexity increases
Solution Approach 1:
The patent creates composite molecular structures where silicon-based functional groups are attached to the THC core. This composite approach enhances therapeutic reliability by improving stability and solubility while maintaining a relatively straightforward synthetic pathway from conventional silicone chemistry.
Solution Approach 2:
The silicon-based functional groups serve multiple functions simultaneously: they improve chemical stability, enhance solubility in cosmetic vehicles, enable thin film formation, and provide controlled release through slow hydrolysis. This multi-functionality justifies the increased molecular complexity by delivering multiple performance benefits from a single structural modification.
