Product Overview

WS-23 is a high-purity synthetic cooling agent renowned for delivering a clean, intense cooling sensation without the minty aroma or flavor associated with traditional menthol. Its unique sensory profile provides an instant, front-loaded cooling effect that is primarily perceived on the front of the tongue and the roof of the mouth. This characteristic makes it an exceptionally versatile ingredient in a wide range of applications, including e-liquids, beverages, confectionery, and oral care, where a pure cooling experience is desired without altering the product’s core flavor profile. As a superior alternative to menthol and other cooling agents, WS-23 offers formulators precise control over the sensory experience.

Applications & Formulation Guidance

WS-23’s clean profile makes it an ideal choice for adding a cooling effect without flavor interference.

  • E-liquids & Vaping: A favorite in the vaping industry, WS-23 provides a smooth, non-intrusive cooling effect that enhances fruit, beverage, and dessert flavors. It does not mute flavor notes like some other additives.
    • Recommended Starting Dosage: 0.1% – 0.5% (1-5 mg/mL) in the final e-liquid.
  • Beverages & Confectionery: Perfect for clear beverages, energy drinks, gums, hard candies, and gummies where a refreshing chill is desired. Its stability ensures the cooling effect lasts throughout the product’s shelf life.
    • Recommended Starting Dosage: 0.01% – 0.2% (100-2000 ppm).
  • Oral Care Products: Effectively used in toothpaste and mouthwash formulations to create a long-lasting sensation of freshness and cleanliness. As the original manufacturer and exporter, we ensure full traceability for sensitive applications.
    • Formulation Note: For best results, pre-dissolve WS-23 in the flavor or solvent phase of your formulation before incorporating it into the main batch.

Our commitment to quality is uncompromising, ensuring your formulation is built on a foundation of purity and consistency.

  • Testing & Methodology: Every lot of our WS-23 is rigorously tested using Gas Chromatography (GC), the industry-standard method for accuracy. This guarantees a purity of no less than 99.0%, ensuring a clean profile free from unwanted impurities and residual solvents.
  • Batch-to-Batch Consistency: As a direct-from-factory supplier, we implement strict process controls and quality checks at every stage of production. This ensures that every batch you receive delivers the identical sensory experience and physical properties, protecting the integrity of your final product.
  • Available Documentation: We provide a comprehensive set of documents to support your quality assurance and regulatory needs.
    • Certificate of Analysis (COA) specific to each batch
    • Material Safety Data Sheet (MSDS)
    • Regulatory Statements (e.g., FEMA GRAS, Allergen, GMO-Free)

Frequently Asked Questions (FAQ)

Q1: What is the main difference between WS-23, WS-5, and Menthol?

A: WS-23 offers a strong, immediate cooling effect at the front of the mouth. WS-5 provides a colder, more lingering effect that is felt in the back of the mouth and throat. Menthol has a distinct minty aroma and flavor, which WS-23 and WS-5 lack.

Q2: How do I dissolve WS-23 powder for my formulation?

A: WS-23 dissolves readily in Propylene Glycol (PG). A common and effective method is to create a 10% or 20% stock solution. To do this, slowly add the WS-23 powder to PG while stirring. Gentle warming (to around 40°C) can accelerate dissolution. This stock solution can then be easily and accurately dosed into your final product.

Q3: Do you supply directly from the factory?

A: Yes, we are the original manufacturer and a global supplier of high-purity WS-23. This direct relationship ensures full traceability, a stable supply chain, and competitive pricing.
