Cooling Agent WS-5: The Strong, Smooth High-Impact Cool That Lasts Up to 30 Minutes

Cooling Agent WS-5 solves a problem few coolants can: it stays cold longer than the product it sits in. Among the strongest cooling agents available, WS-5 delivers a smooth, well-rounded wave that holds for up to a full half hour. Because it centers its effect on the roof of the mouth and the back of the tongue, the cool feels balanced rather than sharp. As a result, formulators building chewing gum, pressed candy and long-format confectionery reach for WS-5 when the cooling must outlast the experience itself.

Why WS-5 leads on strength and staying power

WS-5 earns its “long-acting, high-impact” label through a rare combination. First, it ranks among the strongest coolants on the market, so a little produces a noticeable, lasting effect. Next, that strength stays smooth and well-rounded, avoiding the harsh edge weaker agents can show at high load. In addition, WS-5 remains virtually odorless and tasteless, which keeps the flavor clean while the cool builds. Most importantly, it sustains the sensation for up to 30 minutes at ≥99% purity (HPLC). Therefore, brands get both impact and endurance from a single ingredient.

Where WS-5 outlasts the product

WS-5 performs best where the cooling has to survive well past the first bite or sip. In chewing gum and pressed candy, it keeps refreshing long after the sweetness fades. Meanwhile, confectionery, chocolate, beverages and dairy use it for a cool that lingers through the whole serving. Furthermore, toothpaste, oral care and e-liquids rely on its steady, long tail. Beyond these, WS-5 enhances toiletries, cosmetics, tobacco products and pharmaceutical preparations. Consequently, one strong coolant covers both quick and slow-consumption formats.

How to extend the cooling curve with WS-5

We supply WS-5 at ≥99% purity (HPLC), as white crystals or a crystalline powder with CAS 68489-14-5. Pre-dissolve it in ethanol or propylene glycol, or dissolve it into your flavor system before dosing. It combines cleanly with other WS grades, so teams blend it to extend the cooling curve exactly as the product demands. 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.
