Introduction: What Is WS-23 Cooling Agent?
WS-23 cooling agent (chemical name: N,2,3-Trimethyl-2-isopropylbutamide, CAS No. 51115-67-4, FEMA 3804) is a premium synthetic cooling agent delivering a clean, fast, flavorless cooling sensation without menthol's strong minty taste or throat irritation. As a leading non-menthol cooling agent, it activates TRPM8 cold receptors for instant refreshment-4–10× more potent than natural menthol, with zero aftertaste and high heat stability (up to 200°C).
Widely known as Koolada WS-23, it's the gold standard for modern formulations where flavor fidelity and smooth cooling matter most.
Key Benefits of WS-23 Cooling Agent
Why choose WS-23 powder over menthol or other synthetic coolants (WS-3, WS-5, Frescolat ML)?
✅ Flavor-Neutral Cooling: No minty, bitter, or medicinal notes-preserves original flavors (fruit, dessert, herbal).
✅ Fast Onset, Clean Finish: Cooling hits instantly (tongue/front mouth), fades smoothly without lingering harshness.
✅ Zero Throat Hit: Non-irritating, ideal for high-nicotine vapes and sensitive oral care.
✅ High Purity & Stability: ≥99% white crystalline powder; heat-resistant, pH-stable, 3-year shelf life.
✅ Cost-Effective: Lower usage rates (0.2–3.0%) vs. menthol; less sensory fatigue.
✅ Regulatory Approved: FDA (GRAS), EFSA, FEMA 3804-safe for food, cosmetics, pharmaceuticals.
Top Applications of WS-23 Cooling Agent
1. Vaping & E-Liquids (Fastest-Growing Segment)
WS-23 for vape juice dominates "ice" flavors (mango ice, watermelon ice) and nicotine salt disposables (20–50mg/mL). It smooths harsh nicotine, boosts refreshment, and won't mask fruit profiles-the most popular cooling agent in vaping.
Usage: 0.5–1.5% in e-liquids; 1.0–3.0% for "super ice" disposables.
2. Food & Beverages
WS-23 cooling agent for food enhances refreshment without altering taste:
Confectionery: Mints, chewing gum, hard candies (offsets sweetener warmth).
Beverages: Carbonated drinks, energy drinks, iced teas, flavored waters.
Dairy: Ice cream, yogurt, sorbets (amplifies cold perception).
3. Cosmetics & Personal Care
WS-23 for cosmetics delivers soothing, non-irritating cooling:
Skincare: After-sun gels (0.8–1.2%), toners (0.3–0.6%), cooling masks.
Oral Care: Toothpaste (0.8–1.2%), mouthwash (1.0–1.5%)-mint-free freshness.
Hair Care: Anti-dandruff shampoos, scalp treatments (relieves itchiness).
Shaving: Gels, aftershaves (reduces irritation, cooling comfort).
4. Pharmaceuticals
WS-23 in pharmaceuticals improves palatability and soothing:
Oral meds: Mask bitter tastes in syrups, tablets, lozenges.
Topicals: Analgesics, muscle rubs, burn gels (cooling relief).
