Bulk Cooling Agent WS-23 Powder Supplier (≥99.5% Assay Pure Powder) | High-Purity Synthetic Factory Direct | Non-Menthol Long-Lasting Flavor & Beverage Cooling Raw Material Manufacturer
Cooling Agent WS-23 has become the global gold standard for modern cooling formulations because it delivers a sharp, clean cooling sensation concentrated at the front of the mouth and tongue without the harsh, bitter, or pungent minty aromas associated with traditional menthol. However, product developers and procurement managers often encounter severe quality inconsistencies with lower-grade commercial WS-23: residual solvent traces causing off-chemical taste, partial crystallization or poor solubility in PG/VG or alcohol bases, batch-to-batch melting point shifts, and unwanted metallic or burning lingering notes.
Our factory utilizes multi-stage recrystallization and precision vacuum rectification to overcome these exact formulation hurdles. Sourcing high-purity precursors and operating under strict GMP chemical safety protocols, we guarantee an ultra-pure (≥99.5% by GC) white crystalline powder. Our WS-23 is completely non-volatile up to 200°C, ensuring zero thermal loss during high-temperature candy boiling, bakery extrusion, or liquid vaporization. Whether you need pharmaceutical-grade pure powder for oral hygiene products, pre-dissolved liquid solutions for beverage blending, or custom cooling masterbatches combining WS-23 with WS-3/WS-12 for full-mouth cooling depth, our facility provides scalable metric-ton capacity, competitive factory-direct pricing, and full batch analytical traceability.

Frequently Asked Procurement & Technical Formulation Questions (FAQ)
L-Menthol has a strong minty smell and can cause tongue burning or bitterness. WS-23 is virtually odorless and targets the front of the mouth with fast impact. WS-3 provides throat/back-of-mouth cooling, while WS-12 provides deep throat cooling with a slow onset. Blending WS-23 with WS-3 creates a complete 360° oral cooling sensation.
Typical effective dosage varies by industry: E-liquids (0.5% - 3.0%), Chewing Gum & Confectionery (0.1% - 0.5%), RTD Beverages (0.01% - 0.05%), and Toothpaste/Mouthwash (0.2% - 0.8%). Because of its high purity, lower dosages are required compared to lower-grade alternatives.
WS-23 has a low melting point (60°C - 63°C). It dissolves readily in warm Propylene Glycol (PG), ethanol, or flavor oils at 40°C–50°C under moderate agitation. Once pre-dissolved into a concentrated stock liquid, it easily mixes into aqueous systems or beverage bases.
Store in original unopened drums with inner sealed PE liners in a dry, well-ventilated area away from direct sunlight and heat sources (below 25°C / 77°F). Under these conditions, the product maintains full chemical potency for **24 months**.
Our standard commercial MOQ is **25kg** (1 fiber drum). For lab R&D trials and flavor testing, we provide **100g to 500g evaluation sample kits** dispatched via express air courier within 24–48 hours along with batch Certificate of Analysis (COA) and MSDS.
Every commercial order includes a complete documentation binder: COA (GC Purity Assay), MSDS/SDS (16 sections), Residual Solvent Test Report, Heavy Metals ICP-MS Analysis, Kosher/Halal Certificates, FEMA/EU Food Additive Declaration, and Certificate of Origin (COO).
