WS-23 is a cooling agent that has little or no odour or taste.This is the 30% Version, extremely strong 
As opposed to other cooling agents, WS-23 is more round and smooth in character.This additive is good for those who enjoy “cool or icy” cooling impacts with less flavour muting than other popular additives.Best way to describe this is to share a review from a third party below USE AT 0.25 to 1% MAX VERY VERY STRONG and is made by The Flavor Apprentice
