Cooling Agent WS-5 CAS：68489-14-5

First and foremost, Cooling Agent WS-5 is a high-intensity synthetic menthane derivative cooling crystal powder, also named N-[(ethoxycarbonyl)methyl]-p-menthane-3-carboxamide. As one of the strongest commercial coolants, it delivers clean, long-lasting cold sensation without bitter aftertaste or strong mint odor. For this reason, flavor factories, oral care brands and cosmetic manufacturers widely adopt this high-potency sensory raw material in diversified production formulas.

To start with, this cooling raw material presents white uniform crystalline powder with faint neutral mint coolness. In addition, it dissolves rapidly in ethanol, propylene glycol and plant oils while only slightly soluble in pure water. Meanwhile, sealed cool dark storage stabilizes its cooling activity for long-term shelf life. On the contrary, prolonged exposure to high humidity will trigger minor agglomeration without core efficacy loss. Besides that, it resists high temperature up to 200℃ during baking and sterilization, retaining stable cooling intensity after thermal processing. Its cooling power reaches 2.5–4 times stronger than ordinary menthol, focusing cold feeling on soft palate and throat areas.

We select high-purity p-menthane carboxylic acid as core synthesis feedstock. Firstly, workers purify crude raw materials to remove terpenoid and solvent impurities. Next, low-temperature amidation and esterification form WS-5 molecular structure. After that, recrystallization and multi-stage fine filtration lift finished purity above 99%. Furthermore, every finished batch undergoes strict HPLC purity and sensory testing. Thus, qualified stable Cooling Agent WS-5 is ready for global bulk shipment.

Compared with menthol and WS-3 coolants, our WS-5 crystal carries far stronger cold stimulation with zero spicy bitter irritation. In addition, low addition dosage (0.01%–0.5%) cuts total coolant usage and avoids overwhelming flavor coverage. Moreover, heat-resistant property fits high-temperature baking and extrusion processing that ordinary coolants cannot match. Meanwhile, odorless trait preserves original fruit, herbal and milk flavors without mint interference.

For instance, it adds deep lasting cold sensation to chewing gum, hard candies and baked pastries without flavor distortion under oven heat.

Blend trace WS-5 into toothpaste, mouthwash and throat lozenges to create fresh long-lasting throat cooling effect.

Beyond edible usage, this cooling crystal serves as skin-refreshing additive in gel masks and boosts rich cold layers in vape liquid formulas.
