Cooling Agent WS-27 (CAS 51115-70-9) is the endurance specialist of the WS cooling agent family. A white crystalline powder from the same isomer series as WS-23, WS-27 is engineered for one advantage above all: staying power. Its low volatility and extended-release character keep products feeling cool from the first bite to the last — a property that has made it a favorite in chewing gum, breath fresheners and long-consumption confectionery.

Cooling Profile & Sensory Characteristics
The cooling of WS-27 starts gently and then lasts — and lasts. This extended, even sensation is exactly what slow-consumed products need. WS-27 shows very low bitterness, no mint character and excellent stability, and it blends perfectly with fast-onset agents such as WS-10 or WS-3 to create layered cooling curves: instant freshness up front, long-lasting coolness behind.

Ready-to-drink beverages, sparkling water, dairy, desserts, candy, gum — adds a fresh, cool finish.

Recommended Use & Dosage
WS-27 is dosed at low ppm levels. Because its effect is extended rather than intense, it is often combined with faster agents at tailored ratios. ZHII’s technical team can recommend WS-27 / fast-agent combinations for your product.
