Products Description
WS-10 Cooling Agent | ≥99% Purity | Long-Lasting Cool Sensation | For Food, Beverages, Oral Care & Cosmetics
Our WS-10 Cooling Agent is a high-performance synthetic cooling agent (chemical name: N,2,3-trimethyl-2-isopropylbutanamide) designed to deliver a clean, long-lasting cool sensation without the minty odor or bitterness of traditional menthol. With a purity of ≥99% (verified by HPLC), this white crystalline powder offers a balanced cooling intensity-3x longer-lasting than menthol (up to 4 hours) and 50% milder than WS-23, making it ideal for sensitive formulations.
Sourced from pharmaceutical-grade raw materials and produced in GMP-certified facilities, WS-10 is heat-stable (up to 200°C) and pH-tolerant (3.0-9.0), ensuring consistent performance in high-temperature processing (baking, extrusion) and acidic/alkaline products (juices, toothpaste). It is tasteless, odorless, and non-irritating, making it suitable for a wide range of applications from candy to skincare.
Compliant with global standards (FDA 21 CFR §172.515, EU 10/2011, FEMA GRAS), our WS-10 undergoes rigorous third-party testing for heavy metals, residual solvents, and purity. Whether you're enhancing coolness in beverages, reducing menthol's harshness in toothpaste, or adding a refreshing feel to cosmetics, our WS-10 delivers reliable, customizable cooling effects trusted by 300+ global brands.

Product Case Studies
Product Success Cases
WS-10 Cooling Agent | ≥99% Purity | Long-Lasting Cool Sensation

Case 1: Beverage Brand – Enhancing Sports Drinks with Sustained Coolness
Challenge: A US sports drink brand's product had short-lived coolness (≤30 minutes) from menthol, leading to 28% customer complaints about "fading refreshment." Menthol's minty flavor clashed with their "fruit-only" branding.
Solution: We replaced 50% of menthol with 0.02% WS-10 in the drink formula. WS-10 extended cooling to 4+ hours and eliminated minty notes, while its stability in acidic (pH 3.8) conditions ensured 12-month shelf life.
Result: Customer complaints dropped to 3%, with 86% rating "long-lasting refreshment." The drink captured 15% of the sports beverage market, driving $8.4M in annual sales and gaining endorsements from pro athletes.

Case 2: Oral Care Company – Reducing Toothpaste Irritation
Challenge: A European toothpaste brand's menthol-based formula caused 22% irritation complaints from sensitive users. Removing menthol led to "no coolness" feedback, dropping sales by 18%.
Solution: We formulated a blend of 0.07% WS-10 + 0.05% menthol (replacing 0.15% pure menthol). WS-10 maintained coolness while reducing harshness, with compatibility tests confirming stability with fluoride and xylitol.
Result: Irritation complaints fell to 2%, and "coolness satisfaction" rose to 90%. The toothpaste became the #1 sensitive-teeth product in EU drugstores, with annual revenue growing by €5.2M.

Case 3: Cosmetics Brand – Soothing After-Sun Lotion
Challenge: An Asian after-sun lotion brand struggled with menthol's volatility-cooling effect faded within 30 minutes, and 31% of users reported "stinging" on sunburned skin.
Solution: We added 0.2% WS-10 to the lotion base. Its non-irritating formula soothed skin, with controlled-release technology extending cooling to 6+ hours. Stability tests confirmed no degradation in 40°C/75% humidity.
Result: User ratings for "soothing coolness" rose to 85%, with stinging complaints dropping to 0%. The lotion became a summer bestseller, with sales growing 120% and winning a "K-Beauty Innovation Award."
