Oral Care
Toothpaste, mouthwash and oral sprays use WS-23 for a clean cooling finish without overpowering mint when combined with other flavors.

Product Description
Cooling Agent WS-23 is a synthetic coolant (N,2,3-trimethyl-2-isopropylbutyramide) supplied as white crystal powder at ≥99% on the supplier sheet, CAS 51115-67-4.
It triggers cold-sensitive receptors without the dominant mint flavor of menthol—positioned as nearly odorless and flavorless icy cooling for formulations that cannot tolerate peppermint character. WS-23 is not interchangeable with WS-3, WS-5, WS-12 or menthol on the same dose line; onset, duration and aroma differ by chemotype.
Supplier literature cites thermal stability to about 200 °C and typical use levels around 30–100 ppm, which matters for baked goods, hot-fill beverages and heat-processed cosmetics. Confirm FEMA/EINECS status for your market on the lot paperwork.
Certificate lines on the trade sheet should be verified on the batch COA—do not assume every logo applies to every shipment.

Applications
Foods
Confectionery, chocolate, dairy, beer, spirits, beverages and chewing gum—pre-dissolve in ethanol or compatible solvent before heat steps if the process exceeds supplier stability guidance.
Cosmetics & Personal Care
Skin creams, shaving foam, sunscreen and shower gel for topical cooling; quote food/cosmetic grade on the PO to match your safety file.
E-Liquids
Common in vape liquids for smooth throat cooling; fix WS-23 assay and solvent system separately from menthol-based flavors.
Medicines
Linctus, anti-itch ointments, oral analgesics and similar OTC formats where long cooling duration is desired at low ppm.
Comparison of Cooling Agents
Supplier comparison tables rank overall cooling intensity roughly as WS-5 > WS-12 > WS-3 > WS-23, with different aroma and mouthfeel profiles: WS-23 with mild mint burst, WS-3 slower back-of-mouth cooling, WS-12 longer peppermint-leaning duration, WS-5 highest activity across oral mucosa.
Quote the exact agent on the purchase order—do not substitute by “cooling agent” alone when a formula was built around one chemotype.
FAQ
What is often confused with WS-23 on purchase orders?
WS-23, WS-3, WS-5, WS-12 and menthol are different cooling agents—state the INCI/chemical name and supplier code on the PO; intensity ranking on marketing sheets is not a substitute for your sensory test.
How does WS-23 differ from menthol in formulations?
Menthol brings mint aroma and can sting at higher levels; WS-23 is positioned as low-odor cooling with longer duration at low ppm—still run compatibility and stability in your base.
Can I use this raw powder as a consumer product?
Supplier notes raw material for production, not personal retail. Repack with appropriate food/cosmetic/tobacco regulatory review.
What sample size is offered?
Trade sheets mention 10–50 g samples—match purity to production COA before bulk release.
Is WS-23 heat stable for baking or hot fill?
Supplier literature states cooling effect remains after heating to about 200 °C—validate in your oven or hot-fill line before scale-up.
What use level should I start with?
Marketing sheets cite roughly 30–100 ppm as a starting band—adjust with panel testing; more coolant is not always better for throat or skin comfort.
