Amorphous Solid Aerosol Composition for Tobacco Sensory Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-combustible aerosol provision devices face challenges in generating a desirable inhalable aerosol using traditional cut rag tobacco blends, which often require high amounts of reconstituted tobacco, leading to undesirable sensory characteristics.
Innovation Solution
An aerosol-generating composition comprising an amorphous solid with a high aerosol-former material content, combined with lamina tobacco, reduces the need for reconstituted tobacco while maintaining acceptable aerosol generation, comprising 40-80% aerosol-former material, 10-60% gelling agent and filler, and up to 20% active substance, with tobacco material present in amounts of 50-95% by dry weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional cut rag tobacco blends are used in non-combustible aerosol provision devices, then aerosol generation is achieved, but high amounts of reconstituted tobacco are required leading to undesirable sensory characteristics
Solution Approach 1:
The patent changes the physical state parameter of the aerosol-former material from conventional forms to amorphous solid form. This parameter change enables the material to achieve superior aerosol generation performance with reduced reconstituted tobacco content, thereby eliminating undesirable sensory characteristics while maintaining effective aerosol delivery
Solution Approach 2:
The patent creates a composite aerosol-former material comprising amorphous solid material combined with specific excipients and flavorants. This composite structure synergistically enhances aerosol generation efficiency, allowing reduced reconstituted tobacco content while maintaining or improving sensory characteristics
2Reliability
If high amounts of reconstituted tobacco are used to achieve desirable aerosol generation, then aerosol formation is maintained, but sensory characteristics deteriorate
Solution Approach 1:
The patent modifies the physical state parameter of the aerosol-former to amorphous solid form, which provides more consistent and reliable aerosol generation performance. This enables reduction of reconstituted tobacco content while maintaining aerosol formation reliability, thereby improving sensory characteristics
3Ease of manufacture
If conventional aerosol-former materials are used in non-combustible devices, then manufacturing is simplified, but aerosol generation performance is insufficient
Solution Approach 1:
The patent changes the physical state parameter of the aerosol-former material to amorphous solid form. This parameter change enhances aerosol generation efficiency and vaporization characteristics while maintaining compatibility with existing non-combustible device manufacturing processes, thus achieving both improved performance and manufacturing feasibility
