Short answer: Cooling Agent Powder Cooling Agent WS-5 is a cooling agent bought mainly by confectionery manufacturers. The three things worth verifying before an order are cooling onset, cooling duration and the documentation that ships with the lot. Standard packing is 1 kg foil bag and 25 kg drum, and a 1 kg to 5 kg trial is normally enough to qualify the material on the bench.
Cooling Agent Powder Cooling Agent WS-5 is a cooling agent produced for industrial formulation rather than for retail sale. Production starts with raw material intake and lot identification, moves through the processing steps that define the material's character, and ends with a release decision against a retained reference standard. The reference is the part most buyers never see, and it is the part that decides whether month six behaves like month one.
Because the material is sold on specification, the useful question is not "what is it" but "what does the certificate say". A lot that meets a written range for cooling onset and cooling duration is worth more than a lot that is merely described as premium, and the difference usually shows up in the filling line rather than in the sample bottle.
Four numbers carry most of the risk in this category: cooling onset, cooling duration, moisture and microbiology. The table below shows what a specification normally covers, and what a buyer should expect to see quoted with measured values.

Cooling Agent Powder Cooling Agent WS-5 is used mainly in confectionery, oral care and beverage. Each application stresses the material differently, so the same grade is rarely optimal everywhere.
Confectionery: in this system the material competes with everything else for the same sensory or functional space. A three point dosage curve — 0.7x, 1.0x and 1.3x of the suggested level — tells you more in one afternoon than three rounds of correspondence.
Oral Care: the constraint here is usually a harsh onset or a bitter tail when the dosage is pushed too high. Start at the lower end of the suggested range, confirm the sensory or analytical result, and only then move up. Pushing the dosage to compensate for a weak raw material is the most common reason a formula becomes unstable later.
Beverage: in this system the material competes with everything else for the same sensory or functional space. A three point dosage curve — 0.7x, 1.0x and 1.3x of the suggested level — tells you more in one afternoon than three rounds of correspondence.
Suggested dosage for Cooling Agent Powder Cooling Agent WS-5 is 0.02–0.10% in the flavour system. Treat that as a starting window, not a target. The useful level depends on what else is in the formula, on the process the material survives, and on the claim the finished product has to support.
A usable certificate quotes measured values, identifies the lot it belongs to, and states the method behind each number. For this category the minimum set is purity by GC, melting point and sensory cooling profile, plus microbiology and a heavy metal statement. If a certificate lists only "conforms" without a value, it is a declaration rather than an analysis.
Ask for the certificate of the lot you will actually receive, not a representative one from last year. The difference shows up when a customer audit asks for traceability.
Standard packing is 1 kg foil bag and 25 kg drum. Trial quantities of 1 kg and 5 kg are normally available, and a production run follows once the specification is agreed in writing. Lead time is typically 7 to 15 working days ex-works, and mixed containers can be consolidated across categories to reach a full load.
The documents that matter at the border are the commercial invoice, packing list, certificate of origin where applicable, and the health or non-GMO declarations some destinations require. These are issued with the shipment rather than after it, because a container held at customs costs more per day than the material is worth per kilogram.
Four variables move the price of Cooling Agent Powder Cooling Agent WS-5 more than anything else: the specification range, the quantity of the run, the packing, and the documentation. A tighter assay is not a marketing claim, it is a yield loss at the plant, and it is priced accordingly. A 1 kg trial and a 25 kg drum are not the same product commercially even when the certificate is identical.
Beware of quotes that are much lower than the market: in this category they usually mean a wider specification, a substitute raw material, or a certificate written for a different lot. The cheapest way to find out is to buy a sample, test it against the specification, and compare the result with the certificate that came with it.
The recurring issue in this category is a harsh onset or a bitter tail when the dosage is pushed too high. It rarely appears in a sample and almost always appears in production, which is why trials should be run in the real matrix rather than in water.
What is the minimum order quantity for Cooling Agent Powder Cooling Agent WS-5? Typically 1 kg for a trial and 25 kg for a production order, though the packing can be adjusted for a first run.
Can you send a sample with its certificate? Yes. Samples of 100 g to 500 g are dispatched with the lot certificate, usually within three working days.
Is the specification negotiable? Within the production window, yes. A narrower assay, a different mesh or a declared allergen position can usually be accommodated, and the answer comes with a sample rather than a promise.
Which documents are supplied? COA for the lot, MSDS, allergen statement, non-GMO statement and packing list.
How is the material packed for export? 1 kg foil bag and 25 kg drum, with an inner food grade liner. Custom packing is possible from 100 kg.
How long does delivery take? 7 to 15 working days ex-works for a standard grade, longer where a custom specification or private label artwork is involved.
If you are specifying Cooling Agent Powder Cooling Agent WS-5 for a new formulation, the fastest route to a decision is a sample with its certificate and a short conversation about the process it has to survive. Send the target values and the application, and the answer will come back with a specification and a lot number rather than a brochure.
