Cooling Agent WS-23

WS-23 is a synthetic, non-menthol high-efficiency cooling agent. It is widely used in food, beverages, oral care products, tobacco/e-liquid, and cosmetics to provide a strong, pure cooling sensation.

Below is a key introduction to WS-23:

Chemical Name and Structure:

Chemical name: N,2,3-Trimethyl-2-isopropylbutyramide or N-Ethyl-2-isopropyl-2,3-dimethylbutyramide (both names refer to the same substance).

Structural features: It is a tertiary amide. Its unique molecular structure enables it to effectively activate cold-sensitive receptors (TRPM8 receptors) in the mouth and on the skin.

Core Characteristics:

High-intensity cooling sensation: The most prominent feature of WS-23 is its highly efficient and strong cooling effect. It does not impart any flavor (such as mintiness) and only produces a pure "icy" sensation.

Odorless and colorless: It is almost odorless and colorless, making it very easy to incorporate into various products without interfering with their original flavor and color.

Good solubility: It has certain solubility in ethanol, propylene glycol, glycerol, vegetable oils, and water (relatively low solubility but sufficient for applications), giving it a wide range of uses.

Good thermal stability: It remains stable under conventional food processing and storage conditions.

Fast-acting: The cooling sensation is produced rapidly.

Pure taste: Compared to some other cooling agents (such as WS-3), it is generally considered to have a purer taste with less bitterness or burning sensation.
