Cooling Agent

Cooling agent, WS-3, WS-5 and WS-12, all are derived from the core structure of menthol, generated through amidation reactions using p-menthane-3-carboxylic acid as the key intermediate. Shenlong Herbal is the professional cooling agent supplier in China, with competitive price and best quality of our products.

1.WS-3 (N-Ethyl-p-menthane-3-carboxamide)
CAS No.: 39711-79-0 | Molecular Formula: C₁₃H₂₅NO
Core Properties: White crystalline powder, persistent cooling (15–20 min), non-irritating.

• Primary Applications:

Oral Care: Toothpaste, mouthwash, and throat lozenges (targets throat cooling, relieves dryness).
Food & Confectionery: Chewing gum, mints, and candies.
Beverages: Beer and alcoholic drinks (enhances refreshment without bitterness).
2.WS-5 (N-[(Ethoxycarbonyl)methyl]-p-menthane-3-carboxamide)
CAS No.: 68489-14-5 | Molecular Formula: C₁₅H₂₇NO₃
Core Properties: 2.5× stronger cooling than WS-3, skin-penetrating, requires high purity (>99%) to avoid bitterness.

• Primary Applications:

Topical Products: Sunscreen, antipruritic creams, and shampoo (rapid skin cooling; replaces menthol).
Functional Foods: Energy drinks and sports supplements (intense "kick" for mental alertness).
Insect Repellents: Sprays/gels (masks chemical odors with cooling sensation)
3.WS-12 (N-(4-Methoxyphenyl)-p-menthane-3-carboxamide)
CAS No.: 68489-09-8 | Molecular Formula: C₁₈H₂₇NO₂
Core Properties: Heat-resistant (stable at 200°C), ultra-long cooling (>30 min), slow-release.

• Primary Applications:

High-Temp Processed Foods: Baked goods, hot beverages, and chocolate (retains cooling after heating)
Long-Lasting Cosmetics: Lip balms, sustained-release mouthwash (reduces reapplication frequency).
