3.Key Sensory Characteristics of WS-23
3.1 Clean Cooling Sensation
WS-23 is recognized for delivering a cooling sensation without the strong characteristic mint aroma associated with menthol. This makes it useful for developers seeking a cooling effect while preserving the intended flavor identity of a formulation.
3.2 Relatively Low Flavor Interference
Compared with strongly mint-flavored ingredients, WS-23 has a relatively neutral sensory profile. It may therefore be considered in flavor systems where a pronounced mint note is not desired.
3.3 Formulation Flexibility
WS-23 can be evaluated as part of different formulation systems, depending on the intended application, ingredient compatibility, processing conditions, and applicable regulations.
