Premium Cooling Agents & Koolada Powder Manufacturer from China

WS-23 (CAS 51115-67-4) is a white crystalline cooling powder of the Koolada family. Unlike menthol it is virtually odorless and tasteless — it produces pure physical cooling on the skin and palate with no bitterness, no tingling and no minty flavor. That makes it the first choice for flavor concentrates, beverages and premium confectionery where the original flavor must stay unchanged.

WS-3 (CAS 39711-79-0) has a slight fresh menthol note and a fast, sharp cooling onset with a mild warm sensation at higher doses — excellent for mint candy and oral care. WS-23 is completely odorless with a softer, longer, more rounded cooling effect, ideal for fruit flavors, beverages and flavor concentrates. Many formulators blend both to balance speed and duration.
