Cooling agent WS-3 (CAS 39711-79-0), chemically known as N-Ethyl-p-menthane-3-carboxamide, is the best-known and most widely used synthetic cooling agent in the world. It delivers a strong, mint-like cooling sensation with a fast onset, making it the first choice for toothpaste, chewing gum, beverages and countless other refreshing products. Here is everything buyers should know about WS-3 — and how to source it with confidence.
What Is Cooling Agent WS-3 (39711-79-0)?
WS-3 is an amide derivative of menthane developed as a non-volatile alternative to menthol. It interacts with the TRPM8 cold receptors to produce a genuine cooling sensation that is noticeably mint-like, which makes it a natural partner for mint flavor systems. With a melting point of about 63 °C and excellent thermal stability, WS-3 withstands baking, cooking and hot-filling processes where menthol would simply evaporate.

Cooling Profile & Sensory Characteristics
WS-3 offers a strong, classic cooling effect with a relatively fast onset and a minty character that blends seamlessly with peppermint and spearmint flavors. The cooling sensation is clean and pleasant at recommended levels, with only mild bitterness at high dosages. In finished products the effect lasts several minutes — noticeably longer than menthol — and it does not flash off during production.
Applications of Cooling Agent WS-3
WS-3 is the workhorse cooling agent across many industries:
Oral Care
Toothpaste, mouthwash, whitening strips and breath fresheners. WS-3 is a standard ingredient in oral care because its mint-like cooling reinforces the flavor system.
Confectionery & Gum
Chewing gum, bubble gum, mint candy, lozenges and throat drops benefit from WS-3’s strong, fast, familiar cooling.
Food & Beverage
Cool-finish beverages, alcoholic drinks, desserts and flavored products where a minty fresh accent is desired.
E-Liquids & Vaping
WS-3 is one of the most requested cooling agents for e-liquid bases, delivering a satisfying throat-cooling effect.
Recommended Use & Dosage
Typical use levels for WS-3 range from roughly 10 to 50 ppm in finished products, depending on the matrix and desired intensity — oral care and gum applications often run higher. Our technical team can advise on the right starting point for your formulation.
