How to Choose Food-Grade Cooling Agent WS-3?

How to Choose Food-grade Cooling Agent WS-3?

Today, we'll discuss this from the following aspects:

1. Product Characteristics and Usage Specifications:
WS-3 is a white crystalline powder, easily soluble in solvents such as water and ethanol, with a melting point of approximately 75-80℃. It has a shelf life of 24 months and should be stored in a cool, dry place in a sealed container. Before use, its purity must be confirmed (usually ≥99%) to avoid impurities affecting the flavor. The dosage needs to be adjusted according to the product type.

2. Safety and Compliance: WS-3 has achieved GRAS (Generally Recognized As Safe) certification and is harmless to humans at prescribed dosages. Its CAS number is 39711-79-0, and its EINECS number is 254-599-0, complying with EU REACH regulations. Note that WS-3 should not be mixed with strong oxidizing agents, and inhalation of dust should be avoided. Store away from fire sources; transportation should follow general chemical requirements.

3. Application Scenarios and Effect Comparison: In the food industry, WS-3 often replaces some menthol in applications requiring low volatility and long-lasting fragrance, such as hard candy and throat lozenges. In daily chemical products, it can enhance the cooling sensation of toothpaste and shower gel without losing its effectiveness at high temperatures. Compared to menthol, WS-3 has a milder cooling sensation, making it suitable for products for children or sensitive individuals; compared to ws-23 (another cooling agent), WS-3 has a stronger cooling sensation but a slightly shorter duration, allowing developers to choose according to their needs.
