Cooling Agent WS-3 CAS：39711-79-0

First and foremost, Cooling Agent WS-3 is mild long-lasting cooling crystal, a popular menthyl carboxamide derivative for sensory flavor formulation. This low-irritation coolant delivers smooth clean coolness without harsh mint pungency. For this reason, flavor producers, oral care brands and cosmetic factories widely use this sensory raw material across multiple production lines.

To start with, this coolant exists as fine white crystalline powder with faint neutral cooling aroma. In addition, it dissolves well in ethanol, PG and vegetable oils, with slight solubility in water. Meanwhile, airtight cool dark storage maintains its stable cooling performance for long shelf life. On the contrary, long-term damp storage will cause slight caking without loss of cooling strength. Besides that, it features moderate cooling intensity and good thermal stability under regular food processing temperatures.

We adopt high-purity menthane carboxylic acid as core synthesis feedstock. Firstly, workers purify raw materials to remove residual solvent and terpenoid impurities. Next, low-temperature amidation reaction forms WS-3 molecular structure. After that, recrystallization and multi-stage fine filtration raise finished purity above 99%. Furthermore, each batch receives strict HPLC and sensory testing before delivery. Thus, qualified stable Cooling Agent WS-3 is ready for global bulk shipment.

Compared with strong WS-5 and irritating menthol, WS-3 offers gentle, well-balanced cool sensation without bitter aftertaste. In addition, it blends harmoniously with fruit, milk and herbal flavors without flavor masking. Moreover, low recommended dosage reduces formula cost while keeping lasting fresh cooling effect. Meanwhile, food and cosmetic dual grades satisfy edible and topical production demands separately.

For instance, it brings mild fresh coolness to fruit hard candies, chewing gum and carbonated soft drinks.

Add trace WS-3 to toothpaste, mouthwash and throat lozenges for comfortable long-lasting oral freshness.

Beyond edible usage, this cooling crystal creates soothing cool touch in gel masks, after-sun lotions and body cooling sprays.
