Cooling Agent WS-23

What Is Cooling Agent WS-23?

Cooling Agent WS-23 is a high-performance synthetic cooling compound widely used across the food, beverage, personal care, pharmaceutical, and tobacco industries. Chemically known as N-2,3-trimethyl-2-isopropylbutanamide, WS-23 appears as a fine white crystalline powder that delivers a clean, intense cooling sensation without the characteristic mint odor or flavor associated with traditional cooling agents such as menthol or peppermint oil.

WS-23 is soluble in ethanol and propylene glycol (PG), making it highly compatible with a broad range of liquid and semi-solid formulations. Its odorless and tasteless profile gives formulators exceptional flexibility when developing products where a neutral sensory background is essential — from functional beverages and confectionery to premium skincare and oral care products.

How WS-23 Differs From Traditional Cooling Agents

Traditional cooling agents — including menthol, peppermint oil, and eucalyptus oil — have long been the industry standard for delivering cooling sensations. However, they come with notable limitations that can restrict their use in modern product formulations:

• Strong characteristic odor that dominates fragrance and flavor profiles
• High volatility at elevated temperatures, reducing shelf stability and processing efficiency
• Bitter or sharp aftertaste at higher dosage levels, which negatively impacts sensory quality
• Limited versatility due to their overpowering mint character, which is incompatible with many flavor systems

Cooling Agent WS-23 was developed specifically to address these shortcomings. It provides a powerful, long-lasting cooling effect while remaining completely odorless and flavorless. This makes it an ideal cooling ingredient for applications where sensory neutrality is a priority — such as fruit-flavored products, dairy formulations, or cosmetic preparations where the base fragrance must remain unaltered.

Cooling Agent WS-23 — Key Product Features

Cooling Agent Product Comparison: WS Series

Extract Makers supplies a full range of WS-series cooling agents, each engineered to deliver a distinct cooling profile in terms of onset location, intensity, and duration. Understanding the sensory characteristics of each variant helps formulators select the most appropriate compound for their specific product application.

WS-23

Delivers a strong, immediate burst of cooling sensation at the front of the mouth. Known for its high-impact, rapid-onset profile and clean finish — the preferred choice for chewing gums, hard candies, and mint-free flavor systems.

WS-12

Produces a mild initial cooling sensation in the mouth, which then intensifies significantly as it reaches the throat. This delayed amplification makes it well-suited for lozenges, throat sprays, and products targeting pharyngeal cooling.

WS-5

Generates a cooling burst at the back of the mouth that progressively extends into the throat, offering a smooth, continuous sensory transition ideal for beverage applications and certain oral care products.

WS-3

Delivers a slow, gradual cooling onset that builds throughout the mouth and lingers at the back palate. Its extended, gentle profile is particularly valued in lip care products, light flavor applications, and sustained-release formulations.

Industry Applications of Cooling Agent WS-23

Thanks to its broad functional compatibility and neutral sensory profile, Cooling Agent WS-23 has been adopted across multiple industries as a versatile and reliable cooling ingredient.

Food & Beverage

WS-23 is widely used as a food-grade cooling additive in confectionery, chocolate products, chewing gum, dairy items, beer, distilled spirits, and functional beverages. Its flavorless nature allows it to enhance cooling perception without interfering with the intended taste profile of the end product.

Oral Care & Personal Care

In toothpaste, mouthwash, breath fresheners, and other oral hygiene products, WS-23 enhances the refreshing sensation without relying on menthol. It is also used in shaving creams, shampoos, shower gels, sunscreen formulations, and lip balms where a clean cooling effect is desired without fragrance interference.

Cosmetics & Skincare

WS-23 can be incorporated into topical skin care formulations to provide a soothing, refreshing sensation upon application. Its compatibility with common cosmetic solvents and emulsion systems makes it easy to integrate into creams, gels, serums, and body lotions.

Flavoring & Fragrance Systems

As a cooling enhancer within mint flavor formulations, spice blends, and light care product lines, WS-23 amplifies the perception of freshness while allowing full control over the aromatic profile of the final product.

Pharmaceutical Applications

WS-23 is used in pharmaceutical preparations including cough syrups, anti-inflammatory ointments, topical analgesics, antipruritic creams, digestive aids, oral analgesics, and heatstroke relief formulations. Its clean sensory profile makes it appropriate for sensitive medicinal products where taste and odor must be carefully managed.

Tobacco & Related Products

In cigarettes, filter tips, and other tobacco products, WS-23 is used to deliver a refreshing cooling effect. It is also noted for its potential insect-repellent properties in specialty applications.
