"Upper Cut" is a complex compound used primarily in the vape cartridge industry as a thickener to eliminate bubble movement and leakage. "Upper Cut" allows the producer to make cartridges at a significantly cheaper cost. Even with 75% "Upper Cut" in a cartridge, the bubble doesn't move!
"Safe to use in any desired ratio for a slow-moving bubble. Dilutes formulas over 50% with no impact on flavor color or viscosity. Blend with terpenes and extracts without cutting quality."
