Professional-Grade Fragrance Oils for Scented Candles

The five fields a specification needs

Here is the test that separates a professional page from a poetic one. Take the listing and write a single line a new employee could follow without asking you anything: wax, oil, load, add temperature, stir, pour temperature, wick, jar, cure. Every number in it comes either from a product page or from a decision you had to make and record. The more the page supplies, the fewer places two batches can diverge without you knowing why.

Nearly everything states a load of some kind, and most candle-focused pages state a cure time and a discolouration line. The measured flash point is the rare one — 18 pages of 107 — and it is the one with a genuine operational consequence, which is why it gets a section of its own below. Note that 32 further pages state only the shared line "Flash point > 93°C (suitable for alcohol-based products)": a threshold for a different application, not a measured value for yours, so we do not count it.

107 pages, scored

Every listed fragrance-oil page was read and scored on the five fields. The thirteen below are the ones that state all five and have every listed size in stock, so you can shortlist, trial and produce from the same product without ever changing what you are buying. Three more pages score five but fail on availability: Blue Ocean has one of its five sizes out of stock, Sage and Cedarwood lists four sizes rather than five, and Vetiver has its 1 kg pack sold out.

One result on that table deserves comment, because it is the strongest argument in this whole guide. The joint-cheapest kilo on the list is also one of the best-documented pages in the range. British Rose at ₹3,068 a kilo states a measured flash point of 192°C, a soy and a paraffin load, "0% vanillin - no discolouration", a cure time, and — notably — rates its own strength as "Moderate" rather than reaching for a superlative. Disclosure and price are not correlated here, which means you do not have to buy up the range to buy a page you can work from.

The production spec card, filled in

This is what the five fields buy you. Below are three complete specification lines, built only from what the product pages state plus the two decisions you have to make yourself. Print one per oil, keep it with the batch records, and hand it to whoever pours when you are not there. Nothing in the "from the page" columns is our opinion; the italic entries are the decisions the pages leave to you.

Look at the Neroli column. Its page states a flash point of 85°C; the wax page states that fragrance goes in at 80–90°C. Those two bands overlap, so an operator following the wax instruction at the top of its range would be adding the oil at or above its stated flash point. The spec card catches that before the first pour, and the fix is a single number: add at 80°C. That is the entire value of a stated field. On British Rose and Cinnamon, both comfortably above 190°C, the question never arises — and knowing that it does not arise is also worth something.

Four oils that score five out of five

Four families, four price points, four fully documented pages, all with the complete 15 g to 1 kg ladder in stock. Each card shows every pack size, the listed price per kilo at each, and how many 200 g candles at 8% each pack makes — the 15 g row shows zero because 15 g is under the 16 g a single candle needs.

Flash point against your add temperature

A flash point is the lowest temperature at which a liquid gives off enough vapour to form an ignitable mixture in air. For a candle maker it is a process boundary rather than a scare story. Your wax page tells you to add fragrance at a temperature; if that reaches the oil's stated flash point you are working at the edge of a measured number, and you should move. The rule is conservative and simple: add below the stated flash point, at the lowest temperature in your wax page's band that still lets the oil blend in fully.

The add band used above is the one the Luxury Soy Wax Chunks page states — fragrance in at 80–90°C, pour at 70–80°C. Eco Soy CSI 400 states 80–90°C with 85°C named and a two-minute stir. Premium Coconut Soy CSI 468 runs much cooler — a stated melting point of 50–53°C and a pour at 58–60°C — which removes the conflict entirely and is one practical reason a low-flash-point oil may suit a coconut-soy build better than a hot soy one. Check your own wax page; the numbers differ, and the lower of the two always governs.

What even a 5/5 page will not tell you

A perfect score means the page gave you five numbers. It does not mean it told you everything, and a guide that stopped here would be selling a false sense of completeness. Here is what is absent from every page in the range, including the thirteen best.

Two of those rows deserve particular care. No CSI page states an IFRA certificate number, amendment number, category number or assessment date — the wording is always a compliance statement plus an in-house usage table, and 36 of the 107 pages do not mention IFRA at all. And only two pages mention an SDS; none attaches one. The correct move is not to assume and not to despair, but to ask, in writing, for the specific oil you are about to buy in quantity. A supplier's willingness to say "the page does not state that" is itself a data point, and choosing a supplier on that basis is the subject of how to choose a reliable fragrance oil supplier.

Using an oil that scores badly — on purpose

Twenty-four pages state none of the five fields, and some carry scents your customers will love. A low score is not a veto; it is a bill. Here is how to write the missing specification yourself, in five steps and one weekend, so a 0/5 oil ends up as well documented in your files as a 5/5 one.
