The Next-Generation Cooling Agent Revolutionizing Global Food, Cosmetics and Tobacco Industries

By /
April 22, 2026 — In an era where sensory experience defines product success, WS-23 (N,2,3-Trimethyl-2-isopropylbutanamide, CAS 51115-67-4) has emerged as the undisputed star of synthetic cooling ingredients, rapidly replacing traditional menthol across food & beverage, personal care, oral care, and e-liquid sectors. Renowned for its clean, long-lasting cooling effect without minty bitterness or irritation, WS-23 is reshaping formulation standards and meeting the rising consumer demand for pure, refined freshness.

A Superior Alternative to Traditional Menthol

Unlike natural menthol, which often carries a strong mint aroma, irritating bite, and bitter aftertaste, WS-23 delivers a smooth, neutral cooling sensation that activates the body’s TRPM8 cold receptors without altering the original flavor profile of products. This odorless and tasteless characteristic makes it highly versatile, allowing formulators to precisely control cooling intensity while preserving the integrity of fruits, floral notes, and complex flavor blends.

Its cooling power lasts 15–30 minutes, significantly longer than conventional options, and remains stable at temperatures up to 200°C, enabling seamless integration into high-heat processes like baking, pasteurization, and cooking—an advantage menthol cannot match.

Key Advantages of WS-23

  • Clean & Pure Cooling: Provides intense, refreshing coolness free of minty smell, bitterness, or burning sensation.
  • Exceptional Stability: Thermally resilient and chemically stable across diverse pH environments, ensuring consistent performance.
  • High Compatibility: Mixes effortlessly with other flavors, cooling agents (such as WS-3, WS-12), and ingredients.
  • Cost-Effective: Effective at low dosages (30–300 ppm), reducing material costs for manufacturers.
  • Safety Assured: Approved as GRAS (Generally Recognized as Safe) by the U.S. FDA and compliant with China’s GB 2760 food safety standards.

Expanding Applications Across Industries

Food & Beverage

WS-23 is a staple in sugar-free candies, chewing gums, sports drinks, and frozen desserts, where it enhances refreshment without overpowering primary flavors. Its heat stability makes it ideal for baked goods like mint chocolates and cool cookies.

Oral & Personal Care

Used extensively in toothpastes, mouthwashes, and lip balms, WS-23 delivers long-lasting oral freshness while avoiding the harsh burn common with menthol. In skincare, it soothes and cools in after-sun lotions, facial masks, and shaving products.

E-Liquids & Tobacco

As a preferred coolant for vape juices, WS-23 provides a smooth, satisfying “ice” or “cool” effect across fruit, candy, and tobacco flavors, significantly improving user experience by reducing harshness and increasing appeal.

Market Surge: WS-23 Leads the Cooling Ingredient Revolution

Driven by the global shift toward clean-label, high-purity ingredients and the booming e-cigarette and functional food sectors, the WS-23 market is projected to exceed $4.5 billion by 2033. Leading manufacturers are scaling up production of 99%+ high-purity WS-23 powder to meet demand from multinational brands in food, cosmetics, and tobacco.

Industry experts note WS-23’s unique ability to balance potency, longevity, and flavor neutrality positions it as irreplaceable in modern product development.

Looking Ahead

As innovation accelerates, WS-23 continues to find new applications in pharmaceuticals, dietary supplements, and even animal care products. With consumer preferences leaning toward milder, purer sensory experiences, WS-23 is set to maintain its leadership as the most critical cooling ingredient of the next decade.

For manufacturers aiming to elevate product sensory quality and stand out in competitive markets, WS-23 is no longer an option—it’s a necessity.
