What is the difference between menthol and ws23?

Cooling effect: WS-23 is known for its clean, immediate cooling impact and has been found to cool primarily at the roof of the mouth, the back of the mouth, and the back of the tongue1. Menthol, on the other hand, offers a cooling sensation accompanied by a distinct almost minty flavor.

menthol does not actually cool you; it tricks your body into feeling cool by activating the same nerve receptors that detect cold. This is a similar mechanism to how  in hot peppers creates a sensation of heat. While it creates a powerful cooling sensation, it does not lower your actual skin or core body temperature, and in some cases, studies suggest it may even slightly decrease sweat rate.
