Low-Water Oral Pouch Filling for Nicotine Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral nicotine products often contain high levels of water and humectants like glycerin and propylene glycol, which can lead to rapid nicotine degradation and oxidation, affecting flavor and sensory experience.
Innovation Solution
An oral pouch product with a filling material comprising a dry mixture of cellulosic material and water-soluble filler, and a liquid mixture of oil and nicotine, where the oil consists of triglycerides and the filling material is free of water or contains less than 5% water, enhancing flavor and sensory effects by using a hydrophobic wrapper to maintain moisture and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water and humectants (glycerin, propylene glycol) are added to oral nicotine products to maintain moisture, then mouthfeel is improved, but nicotine degradation and oxidation occur more rapidly
Solution Approach 1:
The invention extracts and removes water and humectants (glycerin, propylene glycol) from the oral nicotine product formulation. By eliminating these components that cause rapid nicotine degradation, the product maintains nicotine stability while achieving moisture-free delivery through the lipid-based system
Solution Approach 2:
The invention changes the chemical composition parameters by replacing water-based and humectant-containing formulations with a lipid-based system. This parameter change transforms the product from hydrophilic to lipophilic, preventing microbial growth and nicotine oxidation while maintaining acceptable mouthfeel through the lipid vehicle
2Stability of the object's composition
If glycerin and propylene glycol are used as humectants, then moisture retention is improved, but product stability and shelf life deteriorate
Solution Approach 1:
The invention extracts and eliminates glycerin and propylene glycol from the formulation. By removing these humectants that compromise long-term stability, the product achieves both moisture retention through the lipid system and extended shelf life by preventing microbial growth and chemical degradation
Solution Approach 2:
The invention replaces long-lasting but unstable humectants with a lipid-based system that provides short-term moisture retention acceptable for oral products while dramatically extending shelf life through inherent stability against oxidation and microbial contamination
3Quantity of substance
If high water content is used in the filling material, then flavor release is enhanced, but microbial growth and nicotine oxidation increase
Solution Approach 1:
The invention changes the water content parameter from high to negligible/zero, and replaces it with a lipid-based system. This parameter transformation maintains flavor release capability through the lipid vehicle while eliminating the harmful effects of microbial growth and nicotine oxidation associated with high water content
Solution Approach 2:
The lipid-based formulation creates an inert, hydrophobic environment that prevents microbial growth and oxidation reactions. This inert atmosphere protects the nicotine and flavor components while still allowing for acceptable flavor release during oral use
