Patented Technology

The Science of Flavor
Transformation

TSAS™ (Transformative Sensory Activation System) is a designed mechanism — not just an ingredient — that delivers an experience that changes over time. Flavor, cooling, intensity, and mouthfeel are all activated by saliva, pressure, or time, releasing a second distinct sensory profile as you use the pouch. One pouch. Two completely different experiences.

1

Place

Place the pouch between your upper lip and gum — just like any other pouch product. Comfortable and discreet.

2

Activate

Your saliva, natural pressure, and time activate the TSAS™ reservoir — a micro-encapsulated sensory core inside the pouch begins to dissolve.

3

Transform

Experience the full sensory evolution — flavor, cooling, intensity, and mouthfeel all transform. Watermelon becomes Watermelon Strawberry. One pouch, two distinct phases.

Patent Pending
Each FUZE pouch contains a dual-layer sensory architecture. The outer layer delivers your primary flavor immediately. Inside, a TSAS™ micro-reservoir holds a concentrated secondary compound sealed within a soluble membrane. Triggered by saliva, pressure, and time, the membrane dissolves and the second flavor gradually emerges — transforming not just the taste, but the cooling, intensity, and mouthfeel of the entire experience.
