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.

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.

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.
