Cross-linked Polysaccharide Fibre Flavorant Provider

The flavor delivery system is segmented into separate components: e-liquid contains nicotine and base liquid without flavorants, while separate flavorant providers (microcapsules, nanocapsules, or flavorant-impregnated materials) deliver flavor independently. This segmentation allows flavorants to be delivered in higher concentrations without being constrained by e-liquid toxicology restrictions, resulting in stronger and more satisfying taste experiences.

The flavorant provider is designed to release flavorants continuously and sustainably during the vaping session rather than all at once. Microcapsules and nanocapsules release flavorant gradually as they are heated and degraded, while flavorant-impregnated materials continuously release flavorant from their porous structure. This continuous release mechanism ensures a sustained and satisfying taste sensation throughout the entire vaping experience.

The flavorant provider uses composite materials that combine the flavorant-impregnating properties of polysaccharide fibers with the thermal and chemical stability of cross-linking agents. The polysaccharide fibers are cross-linked to form a stable three-dimensional network structure that maintains its integrity at device temperatures and in contact with solvents, while still allowing sustained flavorant release through controlled degradation of the cross-linked structure.

The cross-linking process uses parameters that are easy to control and achieve during standard manufacturing: immersion in a cross-linking solution at elevated temperatures for a specified time. This simple parameter-based approach creates stable cross-linked polysaccharide fiber structures without requiring complex equipment or multi-step processes, maintaining ease of manufacture while achieving the desired durability.
