Chewable Nicotine Tablet Solid Solution Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nicotine, due to its volatile and sensitive nature, poses processing and stability issues in existing nicotine delivery products, such as chewing gums, leading to potential degradation and loss during incorporation, which affects the efficacy and shelf life of these products.
Innovation Solution
A chewable dissolvable nicotine tablet is developed, comprising a solid solution of soluble fiber and sugar alcohols with nicotine dispersed within, where the mixture is heated to a controlled temperature below 150°C to prevent cross-linking, maintaining stability and allowing for a glass transition temperature suitable for ambient and body temperatures, ensuring a stable and enjoyable tactile experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional heating methods are used to incorporate nicotine into chewing gum or lozenges, then the nicotine can be integrated into the product matrix, but the nicotine degrades and evaporates during processing, reducing product efficacy and shelf life
Solution Approach 1:
The patent changes the temperature parameter from traditional high-temperature processing to low-temperature processing (below the glass transition temperature of the matrix), preventing nicotine degradation and evaporation while still achieving proper incorporation into the product
Solution Approach 2:
The patent uses a composite matrix system combining sugar alcohol, soluble fiber, and nicotine, where each component serves a specific function: sugar alcohol provides the base matrix, soluble fiber enhances structure and reduces nicotine release rate, and nicotine provides the active ingredient, creating a synergistic formulation that maintains stability
2Stability of the object's composition
If the glass transition temperature of the solid solution is lowered for better chewability at ambient temperature, then the product becomes too soft and loses structural integrity, but if it is raised for stability, then the product becomes difficult to chew at body temperature
Solution Approach 1:
The patent optimizes the glass transition temperature parameter to a specific range (10°C to 40°C) that balances structural integrity at ambient temperature with chewability at body temperature, achieving both stability and ease of operation through precise parameter control
Solution Approach 2:
The patent creates different functional zones within the product: the matrix structure provides structural integrity at ambient temperature, while the nicotine-containing regions provide controlled release and tactile sensation during chewing, with each zone optimized for its specific function
3Reliability
If soluble fiber content is increased to improve product stability and reduce nicotine release rate, then the product becomes less palatable and harder to chew, but if it is decreased, then nicotine release becomes too rapid and stability is compromised
Solution Approach 1:
The patent optimizes the soluble fiber content parameter to a specific range (10% to 50% by weight) that balances nicotine release control with acceptable mouthfeel and chewability, achieving the optimal compromise between release rate control and sensory properties
