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.
What Is Cooling Agent WS-27 (51115-70-9)?
WS-27 shares its chemical family (and CAS series 51115-xx) with WS-23 and WS-2, but its specific isomer structure gives it markedly lower volatility and a slower release profile. It is odorless to slightly characteristic in odor, works through the TRPM8 cold receptors, and remains stable through heat processing. For formulators, WS-27 is the tool that keeps cooling alive long after faster agents have faded.

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.
Applications of Cooling Agent WS-27
WS-27 shines wherever cooling must endure:
Chewing Gum & Breath Fresheners
The classic application. WS-27 keeps gum and breath strips feeling cool throughout the chewing time, not just in the first seconds.
Confectionery
Slow-dissolve candies, lollipops and mints that deliver cooling across the entire consumption experience.
Beverages
Provides a stable, lingering cool finish in ready-to-drink products.
Personal Care
Body and foot care products where a long-lasting fresh-cool feeling is part of the product promise.
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.
Packaging & Storage
Cooling Agent WS-27 is typically supplied in 1 kg aluminum foil bags and 25 kg fibre drums; custom packing is available on request. Store in a cool, dry place away from direct sunlight, tightly sealed to protect the powder from moisture. When stored properly, the product remains stable for at least 24 months from the production date.

Frequently Asked Questions
What makes WS-27 different from WS-23?
WS-27 comes from the same isomer family but releases its cooling more slowly and lasts longer. WS-23 is the stronger all-rounder; WS-27 is the endurance specialist. Many formulations use both together.
Is WS-27 suitable for chewing gum?
Yes — chewing gum and breath fresheners are its flagship applications, precisely because its cooling persists for the whole chewing time.
Can ZHII supply WS-27 in bulk?
Yes. WS-27 is available from 1 kg packs to full container loads, with COA per batch, KOSHER/HALAL certification and worldwide shipping.
