Cooling Agent WS-23 CAS：51115-67-4

First and foremost, Cooling Agent WS-23 is odorless synthetic cooling crystal with CAS 51115-67-4, an aliphatic TRPM8 agonist without menthol structure. It delivers clean fast cooling focused on tongue and front palate, carrying zero mint odor or bitter aftertaste. For this reason, flavor factories, oral care brands and e-liquid manufacturers widely adopt this flavor-friendly coolant for multi-scene production lines.

To start with, this cooling raw material is uniform white crystalline powder with neutral scent. In addition, it dissolves fully in propylene glycol, ethanol and plant oils while insoluble in pure water. Meanwhile, sealed cool dark storage maintains stable cooling activity for up to 3 years. On the contrary, long-term high humidity will trigger mild agglomeration without losing cooling strength. Besides that, it withstands 200℃ high-temperature baking, features fast cooling onset and leaves a clean palate without throat irritation.

We select high-purity aliphatic alkyl raw materials as exclusive synthesis feedstock. Firstly, workers purify crude feedstock to remove solvent and alkane impurities. Next, low-temperature amidation reaction forms standard WS-23 molecular structure. After that, recrystallization and multi-stage fine filtration lift finished purity above 99%. Furthermore, every finished batch receives strict HPLC and sensory panel testing. Thus, stable qualified Cooling Agent WS-23 is ready for global bulk shipment.

Compared with WS-3, WS-5 and menthol, WS-23 has zero inherent mint aroma that never masks fruit, berry or tropical flavors. In addition, its cooling sensation concentrates on the front tongue without harsh throat hit or coughing reflex. Moreover, low recommended addition dosage cuts formulation costs and supports high-temperature food processing. Meanwhile, food and cosmetic dual grades fit edible, oral and topical formula demands separately.

For instance, it adds pure icy freshness to fruit sodas, hard candies and chewing gum without covering original fruity notes.

Blend trace WS-23 into toothpaste and mouthwash for light fresh cooling comfort on the tongue.

Beyond edible usage, this cooling crystal acts as core icy sensory additive for vape juice and after-sun cooling skincare gels.
