Cooling Agent WS-12: Maximum Intensity with a Throat-Focused Cool

Cooling Agent WS-12 sits at the top of the WS series for one reason: intensity. It delivers the highest cooling strength in the entire range, paired with a throat-focused sensation that ordinary menthol cannot reproduce. Because WS-12 also carries a melting point of 179-183°C, it keeps its cooling power through baking, extrusion and hot-fill manufacturing. As a result, formulators who need maximum impact in e-liquids, baked goods and oral care turn to WS-12 when nothing milder will do.

Why WS-12 delivers maximum intensity with a throat focus

WS-12 earns its place as the series’ strongest coolant through a distinctive sensory profile. First, it produces the highest cooling intensity of any WS grade, so a small dose registers immediately. Next, that cooling concentrates on the throat and spreads a fresh, aromatic lift across the whole mouth — an effect menthol cannot match. In addition, WS-12 stays free of bitterness, burning and tingling, which keeps the experience clean at high load. Most importantly, it reaches ≥99% purity (HPLC) as a white crystalline powder. Therefore, brands get peak impact without the off-notes that weaker agents show under stress.

Where the throat focus makes the difference

WS-12 performs best where a deep, throat-level cool defines the product. In e-liquids and vape, it creates the crisp throat hit users expect. Meanwhile, baked goods and high-temperature processed foods rely on its heat-stable cooling, since the high melting point survives the oven. Furthermore, confectionery, toothpaste, oral care, toiletries, cosmetics, tobacco filter tips and OTC preparations use it for a lasting, full-mouth refresh. Consequently, one maximum-intensity grade covers both hot-process and sensory-led formats.

How to formulate with WS-12 at high temperature

We supply WS-12 at ≥99% purity (HPLC), as a white crystalline powder with CAS 68489-09-8 and FEMA 4681. Dissolve it in ethanol or propylene glycol first, then add it to the water phase — or pre-dissolve it into your flavor system before dosing. Its high melting point (179-183°C) lets it pass through baking, extrusion and hot-fill steps without losing cooling power. It also blends with other cooling agents for layered effects. We pack in 1 kg aluminium-foil bags and 25 kg fiber drums, with custom packing on request. So request a sample and COA today, and our team will confirm pricing and lead time within one business day.
