Cooling agent WS-11 (CAS 87061-04-9) belongs to the same CAS family as WS-10 and is prized for its strong initial cooling impact. A white crystalline powder produced to the same high-purity standard as the rest of the WS series, WS-11 gives flavorists a powerful tool for products that open with a bold, immediate cool sensation. This guide explains its character, applications and sourcing options from ZHII.
What Is Cooling Agent WS-11 (87061-04-9)?
WS-11 shares the CAS registry number 87061-04-9 with WS-10 — the two grades come from the same chemical family and are produced to identical purity standards, with each optimized for slightly different sensory nuances. Like all WS-series agents, WS-11 activates the cold receptors directly, giving stable, non-volatile cooling that survives processing where menthol would evaporate.

Cooling Profile & Sensory Characteristics
WS-11 is characterized by a strong, front-loaded cooling effect. The initial hit is bold and unmistakable, followed by a moderate cooling tail. This high-impact opening makes WS-11 especially effective in flavors designed around intensity — icy fruit concepts, strong mints and “frozen” beverage profiles. It pairs naturally with longer-lasting agents such as WS-12 or WS-27.
Applications of Cooling Agent WS-11
WS-11 is chosen where cooling impact is the headline feature:
Flavor Compounds
A building block for intense “icy” and “polar” flavor systems used across food and beverage manufacturing.
Beverages
Energy drinks, sparkling waters and frozen-drink mixes that promise an immediate cold sensation.
Confectionery
Strong mints, frozen-style candy and intense gum varieties.
E-Liquids & Vaping
Delivers a bold, satisfying cooling opening in high-impact e-liquid formulations.
Recommended Use & Dosage
WS-11 is dosed at low ppm levels; because its impact is strong, conservative starting levels are recommended with upward tuning after sensory trials. Contact ZHII for application-specific guidance.
Packaging & Storage
Cooling Agent WS-11 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.

Frequently Asked Questions
What is the relationship between WS-11 and WS-10?
They share the same CAS number (87061-04-9) and belong to the same chemical family. WS-11 is typically selected for its strong initial cooling impact, while WS-10 is often chosen for its bright, fast attack. Many customers evaluate both and select based on their target sensory profile.
Is WS-11 suitable for fruit flavors?
Yes — its neutral, low-odor character makes WS-11 an excellent cooling partner for icy fruit flavor concepts without altering the fruit profile itself.
