Why WS-12 is Transforming E-Liquids
-
Superior Cooling Performance:
-
Delivers a 1.5× stronger and 15–20 minute cooling effect compared to menthol, without the bitter aftertaste.
-
Works synergistically with WS-23 and koolada to amplify icy sensations in nicotine salts and flavored e-juices.
-
Technical Advantages:
-
Thermal Stability: Retains efficacy at temperatures up to 300°C, ideal for sub-ohm and pod-based vaping devices.
-
Low Usage Rate: Effective at concentrations as low as 0.1–0.5%, minimizing formulation costs.
-
Safety & Compliance:
-
Classified as GRAS (Generally Recognized as Safe) for inhalation by independent labs.
-
Compatible with VG/PG bases and nicotine formulations, meeting FDA and TPD (EU) guidelines.
Industry Adoption & Case Studies
Leading e-liquid brands like ICE Vapor Co. and Frost Labs have integrated WS-12 into flagship products:
-
Nicotine Salt Blends: Reduces throat irritation while enhancing mint/menthol profiles.
-
Fruit & Dessert Flavors: Adds a crisp "frosted" layer to mango, watermelon, and vanilla custard e-liquids.
-
CBD Vape Oils: Masks herbal bitterness and creates a cooling finish for cannabis-derived products.
“WS-12 lets us push the boundaries of
\ncooling without overwhelming the flavor. It’s a game-changer for high-VG
\n cloud-chasing juices,” said Alex Rivera, Chief R&D Officer at CloudCraft E-Liquids.
