Cooling Agent WS-27: Mild Cooling for Leave-On Skin Care
What Is Cooling Agent WS-27?
Cooling Agent WS-27 is a food-grade synthetic cooling agent. Its chemical name is N-Ethyl-2,2-diisopropylbutanamide, and many buyers also call it Koolada WS-27. WS-27 sits at the newest point of the WS series, and it refines what WS-23 started.
First, WS-27 carries a compact branched amide structure. Therefore, it dissolves faster than older burst grades. Second, it activates the TRPM8 cold receptor mainly at the front of the mouth and on the tongue. As a result, the burst lands exactly where tasters notice it first.
Third, our proprietary process removes the bitter note that earlier generations left behind. In other words, you get the burst without the cost to flavor. WS-27 also holds FEMA number 4557 and CAS number 51115-70-9. Consequently, it fits both food and cosmetic programs with no extra paperwork.
