n the food, daily chemical, and pharmaceutical industries, the sensation of cooling has always been a key experiential dimension sought by consumers. However, traditional cooling agents like menthol, while delivering an instant chill, often come with pungent odors, irritating spiciness, bitterness, and even numbing effects—limiting product applications and user experience. Enter WS-23, a new-generation cooling agent that is quietly sparking a cooling revolution.

WS-23 (Chemical Name: N,2,3-Trimethyl-2-isopropylbutanamide) is a non-menthol synthetic cooling agent whose core value lies in pure cooling sensation. It is nearly odorless and tasteless, does not interfere with the product’s own flavor profile, yet delivers a powerful and long-lasting cooling experience.

Key Advantages of WS-23
1. Pure Cooling Sensation
The greatest breakthrough of WS-23 is that it eliminates all “side effects” of traditional menthol. It has no bitterness, pungency, burning sensation, or numbness, and creates an impactful, fresh aroma across the oral mucosa and throat.

2. Superior Long-Lasting Effect
The cooling effect of WS-23 can last 15 to 30 minutes, far exceeding traditional cooling agents, and the cooling sensation is superior to that of menthol-based products.

3. Excellent Heat Resistance
WS-23 exhibits outstanding thermal stability—heating below 200°C does not reduce its cooling intensity, making it ideal for baked goods, high-temperature processed candies, and other products requiring heating processes.

4. Low Dosage, High Efficiency
WS-23 delivers remarkable cooling effects at extremely low dosages, with a recommended usage of only 30-100 mg/kg, offering excellent cost-effectiveness.

Wide Range of Applications
With its unique cooling characteristics, WS-23 has become an ideal choice across numerous industries:

Food & Beverages: Confectionery, chocolate, chewing gum, baked goods, dairy products, beer, distilled spirits, and various beverages

Daily Chemical Products: Toothpaste, mouthwash, air fresheners, skin creams, shaving cream, shampoo, sunscreen, shower gel

Pharmaceutical Products: Cough syrups, anti-inflammatory ointments, antipruritics, liniments, oral analgesics, heatstroke pills
