Cooling Agent WS-3: The Industry Standard for Clean, Long-Lasting Mouth Cooling

Cooling Agent WS-3 did not become the market’s most widely used coolant by accident. As a menthol derivative that stays virtually non-volatile, odorless and tasteless, it delivers an immediate, clean cool that lingers 15-30 minutes without the burning or bitterness of peppermint. Because WS-3 concentrates its effect on the roof and back of the mouth, it gives formulators a dependable, long-lasting sensation they can build a whole product around. For this reason, brands across confectionery, beverages, oral care and e-liquids treat WS-3 as their default cooling benchmark.

Why WS-3 became the industry benchmark

WS-3 earns its standing through consistent, well-understood performance. First, it cools immediately yet sustains the effect for 15-30 minutes, so a single dose carries through an entire use. Next, it avoids the stinging and bitterness that limit peppermint, which keeps flavor profiles clean. In addition, its near-zero volatility means the cool stays in the product instead of drifting off during storage. Most importantly, WS-3 reaches ≥99% purity (HPLC) and dissolves reliably in PG or VG at just 30-100 mg/kg. Therefore, manufacturers trust it as the reference point against which newer coolants are measured.

Where WS-3 sets the standard

WS-3 covers a broader application list than almost any sibling. In beverages, beer and distilled spirits, it adds a clean mouth-cool that survives the glass. Meanwhile, confectionery, chocolate, chewing gum and dairy rely on its lasting refreshment. Furthermore, toothpaste, oral care and e-liquids use it as the everyday standard. Beyond these, WS-3 extends into skin cream, shaving cream, shampoo, sunscreen, shower cream, air fresheners, tobacco filter tips, OTC liniments, oral analgesics and even insect-repellent formulations. Consequently, one ingredient anchors both consumer and functional product lines.

How to get more from WS-3

We supply WS-3 at ≥99% purity (HPLC), as white crystals or a crystalline powder with CAS 39711-79-0. Pre-dissolve it in ethanol or propylene glycol, then add it to the water phase — or dissolve it into your flavor system first and dose from there. For a stronger scent story, blend it with dementholized peppermint oil, which significantly boosts the fragrance signature. 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.
