Cooling Agent WS-27: The Refined Next-Generation Burst That Beats Bitter Aftertaste

Cooling Agent WS-27 takes everything formulators liked about WS-23 and removes the one thing they didn’t: the bitter tail. Our proprietary process delivers finer, faster-dissolving crystals and a high-purity coolant with no bitter aftertaste from earlier generations. Because WS-27 concentrates its cooling on the front of the mouth and the tongue, it produces a clean, high-intensity burst that hits instantly. As a result, brands upgrading their toothpaste, confectionery and next-generation e-liquids now choose WS-27 as the obvious successor.

Why WS-27 is the upgrade formulators asked for

WS-27 earns its “refined next-generation burst” label through measurable gains. First, its crystals are finer and dissolve more easily than WS-23, which simplifies handling in liquid systems. Next, the proprietary process strips out the bitter aftertaste that older coolants left behind, so the flavor stays clean from the first contact. In addition, WS-27 keeps a high burst and high intensity while focusing cooling on the tongue and front palate. Most importantly, it reaches ≥99% purity (HPLC) without sacrificing solubility in PG or VG. Therefore, teams get a smoother coolant that performs at lower effort.

Where the new burst performs best

WS-27 shines in products where a bright, immediate cool defines the experience. In toothpaste and oral care, it delivers fresh breath with no bitter edge. Meanwhile, confectionery makers use it for a high-impact hit that lingers just long enough. Furthermore, next-generation e-liquids rely on its front-of-mouth focus for a crisp draw. Beyond these, WS-27 enhances beverages, toiletries, cosmetics, tobacco products and physiological coolants in pharmaceuticals. Consequently, one upgrade serves both legacy lines and new launches.

How to switch from WS-23 to WS-27

We supply WS-27 at ≥99% purity (HPLC), as white crystals or a crystalline powder with CAS 51115-70-9. Pre-dissolve it in ethanol or propylene glycol, or dissolve it directly into your flavor system before dosing — its excellent solubility makes the changeover straightforward. 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.
