Short answer: Colorless Or Light Yellow Oily Liquid is a colour material bought mainly by beverage manufacturers. The three things worth verifying before an order are colour value, light stability 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.
Colorless Or Light Yellow Oily Liquid falls into the colour material 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: colour value, light stability, 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 | Colorless Or Light Yellow Oily Liquid | — |
| Category | Pure Plant Extract | — |
| Appearance | Conforms to the retained reference | Visual |
| Colour Value | Within the agreed release range | In-house / third party |
| Light Stability | Quoted on the certificate | In-house |
| Dispersion | Verified before release | In-house |
| Suggested dosage | 0.02–0.20% in the colour base | Application trial |
| Microbiology | Within food grade limits | ISO 4833 / ISO 21527 |
| Heavy metals | Below the destination market limit | ICP-MS |

Colorless Or Light Yellow Oily Liquid is used mainly in beverage, confectionery and dairy. Each application stresses the material differently, so the same grade is rarely optimal everywhere.
Beverage: the constraint here is usually colour fade under retail lighting. 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.
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.
Dairy: the constraint here is usually colour fade under retail lighting. 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.
Suggested dosage for Colorless Or Light Yellow Oily Liquid is 0.02–0.20% in the colour base. 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 colour value by spectrophotometer, light stability and dispersion, 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 Colorless Or Light Yellow Oily Liquid 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 colour fade under retail lighting and specking in low-fat systems. 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 Colorless Or Light Yellow Oily Liquid? 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 Colorless Or Light Yellow Oily Liquid 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.
