Short answer: Extract Pyrethrum Yellow Liquid Oil is a essential oil bought mainly by fragrance compounds manufacturers. The three things worth verifying before an order are GC profile, odour intensity and the documentation that ships with the lot. Standard packing is 5 kg and 25 kg epoxy-lined drum, and a 1 kg to 5 kg trial is normally enough to qualify the material on the bench.
Extract Pyrethrum Yellow Liquid Oil falls into the essential oil category. In commercial terms it is defined by three things: the specification range it is released against, the packing it ships in, and the documentation that accompanies it. Two suppliers can quote the same product name and still deliver materials that behave differently, because the release ranges behind the name are not the same.
That is why a technical data sheet and a certificate of analysis are read together. The data sheet describes what the supplier intends to make; the certificate describes what was actually made. When the two disagree, the certificate is the one that matters for your batch record.
Four numbers carry most of the risk in this category: GC profile, odour intensity, moisture and microbiology. The table below shows what a specification normally covers, and what a buyer should expect to see quoted with measured values.
| Parameter | Typical value | Method |
|---|---|---|
| Product | Extract Pyrethrum Yellow Liquid Oil | — |
| Category | Pure Plant Extract | — |
| Appearance | Conforms to the retained reference | Visual |
| GC Profile | Within the agreed release range | In-house / third party |
| Odour Intensity | Quoted on the certificate | In-house |
| Clarity | Verified before release | In-house |
| Suggested dosage | 0.10–1.0% in the fragrance concentrate | Application trial |
| Microbiology | Within food grade limits | ISO 4833 / ISO 21527 |

Applications for Extract Pyrethrum Yellow Liquid Oil cluster around fragrance compounds, personal care and household care. The differences between them matter more than the similarities, because the failure mode changes with the matrix.
Fragrance Compounds: 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.
Personal Care: the constraint here is usually adulteration with cheaper fractions. 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.
Household Care: 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 Extract Pyrethrum Yellow Liquid Oil is 0.10–1.0% in the fragrance concentrate. 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 GC-MS profile, optical rotation, relative density and acid value, 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 5 kg and 25 kg epoxy-lined 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.
The same material can be a food ingredient in one market and a regulated substance in another, so the destination decides the paperwork. In the European Union the relevant framework is the food additive and flavour regulation set, with labelling driven by the allergen list. In the United States the equivalent conversation is about GRAS status and FDA labelling. In much of Asia the requirement is a health or food safety declaration issued at the border.
None of this changes what the material is. It changes what has to be written on the label and which certificate has to travel with the pallet, and it is worth settling before the artwork is printed.
Four variables move the price of Extract Pyrethrum Yellow Liquid Oil 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 adulteration with cheaper fractions and batch-to-batch odour variation. 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 Extract Pyrethrum Yellow Liquid Oil? 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? 5 kg and 25 kg epoxy-lined 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.
Buying Extract Pyrethrum Yellow Liquid Oil is a documentation exercise as much as a purchasing one. The suppliers worth keeping are the ones whose certificate matches the drum, whose lead time holds in a busy quarter, and who answer a technical question with a value rather than an adjective.
