Should I Approve Every New Fragrance Oil Through a Separate Burn Test?
शेयर करना
What is the minimum test? Three candles poured from one melt: the new oil on your house wick, the new oil on one wick size up, and an oil you have already approved as the reference. Pool log at day 3, blind burns at day 7 and day 14. Add a fourth, never-lit candle for colour if you pour pale wax.
How much does it cost? A 50 g bottle plus three candles' worth of wax, jars and wicks: ₹764.50 for Mango Coconut, ₹962.50 for Gilli Mitti. The 1 kg of the same oils, bought untested, is 5.2 to 9.3 times that.
When is a shorter check enough? A reorder of an oil you already approved, from the same supplier, needs one confirmation candle beside your kept sample, not the full test. A new supplier, wax or jar means a new approval.

Why every new oil, even from a supplier you trust
The temptation to skip approval is strongest when things are going well. Your first five oils from a supplier worked, the new one's page states a sensible load range and says "Strong throw", and a customer review calls it lovely. None of that is evidence about your candle. Here is what each of those signals is, honestly, and what it cannot tell you.
| Reason to skip | What it does tell you | What it cannot tell you |
|---|---|---|
| "The supplier's other oils work for me" | The supplier's wax or quality suits you in general | This oil's structure, density and wick needs, which differ from oil to oil |
| "The page states 7–11% and Strong throw" | The intended window; the page's own description | Performance in your wax. Throw wording is a claim on the page, including on CSI's pages; CSI publishes no measured throw data |
| "A review says it is lovely" | One customer liked it, in their system | Your jar, wick and room; some reviews are written before the oil is ever poured |
| "It smells strong in the bottle" | The top notes are concentrated at your nose | Hot throw; strong cold throw does not predict hot throw |
| "It is the same scent as one I sell" | The character may be similar | A different oil is a different formulation, even under the same name |
The review row is not hypothetical. One published review on CSI's store, for a jasmine oil, reads "Can't wait to use in my candles": a sincere, positive review written before the oil had been in a candle. Reviews are worth reading and worth one test candle; they are not approval. Why oils that share a formula still behave differently is set out in the hub for this cluster.
What counts as "new", and when a shorter check will do
The question in the title has a practical edge: approval takes 14 days, and a busy maker cannot re-approve everything every time. The rule we suggest is simple. Anything that changes the oil, the wax or the jar triggers a new approval; a repeat of an approved combination needs only a confirmation that nothing has changed.
| Situation | Test | Why |
|---|---|---|
| An oil you have never poured | Full minimum approval (3 candles) | No evidence yet in your system |
| The same scent name from a new supplier | Full minimum approval | A different formulation, whatever the name |
| An approved oil in a new wax | Full minimum approval, and check the new wax's ceiling | Wax changes pool, ceiling and temperatures |
| An approved oil in a new jar size | Wick twin in the new jar | The jar sets the pool; see retesting the wick after a change |
| An approved oil at a new load | Load comparison beside the old load | Load changes pool and surface |
| An approved oil reordered, same supplier and size | One confirmation candle beside your kept sample | Checks the new bottle matches; see the small-test-versus-bulk post |
| An approved oil ordered at 5 kg | Confirmation plus repeat-batch checks | See the 5 kg order tests |
| A new dye colour for an approved oil | A never-lit shelf candle for colour | Dye and fragrance can interact visually |
Two habits make this workable. Keep 20 to 30 g of every approved sample, sealed and labelled, so a confirmation candle has something to be compared with. And keep one line per approved oil: wax, jar, wick, load, date approved. A new supplier or jar then shows up as a line that does not exist yet.
The minimum approval test: three candles, fourteen days
This is the smallest test we would trust for putting an oil into production at your house settings. It deliberately does not try to find the oil's best load; it asks whether the oil works at the load you already use, inside the lower of its page maximum and your wax page's maximum. If you want the oil at a different load, or you are deciding whether to stock it at all, that is the full qualification in How to Qualify a New Fragrance Oil Before Adding It to Your Candle Business.
| Candle | Oil | Wick | Question |
|---|---|---|---|
| N1 | New oil, 12 g | House wick (C1 in the example) | Does it work on your current settings? |
| N2 | New oil, 12 g | One size up (C2) | If N1's pool falls short, is the fix a wick? |
| R | An approved oil, 12 g | That oil's approved wick | Is the new oil as good as what you already sell? |
| S (optional) | New oil, 12 g | House wick, never lit | For pale wax or vanilla-bearing oils: colour and sweating on the shelf |
New oil used: 24 g for three candles, 36 g with the shelf candle, leaving 26 g or 14 g in a 50 g bottle for one confirmation candle later. A 15 g bottle covers N1 only, which is why 15 g is a sniff test, not an approval.
| Check | Pass | Fail means |
|---|---|---|
| Melt pool at hour 3 to 4 | To the glass, roughly 0.5 to 1 cm deep (a commonly cited rule of thumb, not CSI data) | Wick question; see the failed-approval table |
| Flame and soot | Steady flame, no soot on the glass | Over-wicked or load too high for this oil |
| Surface at day 14 | No sweating, wet spots or pooled oil | Load may be above what the wax holds with this oil |
| Doorway score at day 14 | Within one point of R, or above | Oil, load or wick; not yet a verdict on the oil alone |
| Colour (pale wax, shelf candle) | A shade you are willing to sell | Jar or dye exception, or a white-wax "no" |
Is it actually the fragrance oil? Reading a failed approval
The reference candle R is what turns a disappointing test into information. If R also performed badly, your system had a bad fortnight, and the new oil has not been tested fairly. If R was fine, the failure belongs to the new oil in these settings, but not necessarily to the oil in every setting.
| R (reference) | N1 (house wick) | N2 (one up) | Meaning | Next step |
|---|---|---|---|---|
| Good | Good | — | Approved at house settings | Write the line; buy stock at the size your volume justifies |
| Good | Short pool, weak | Full pool, close to R | Approved with a wick exception | Record C2 for this oil; nothing else to buy |
| Good | Weak | Weak, full pool | The oil underperforms at this load in your system | Full qualification (load ladder within the ceiling) or reject |
| Good | Sweating or soot | Sweating or soot | This oil at 8% may be too much for the wax, or the wick too hot | Qualification at a lower load; do not approve yet |
| Weak | Weak | Weak | The system, the room or the day failed, not the new oil | Buy nothing; repeat with a fair room and fresh nose |
The last row matters most for your wallet. If your reference oil, which you sell happily, scored weakly in this test, the fault is in the test, and replacing the new oil would repeat the fault with a different bottle. How to stop a genuinely poor oil before it becomes stock, and the kill criteria at each stage, are in How to Reject Poor-Performing Fragrance Oils Before They Become Expensive Inventory.
What approval costs, per oil and for four at once
Per oil, the cash is the 50 g bottle; the rest is wax, jars and wicks you would have bought anyway. For the four oils in the chart, with CSI 464 at ₹0.51 per gram (10 kg price), 150 g clear jars at ₹94.40 and Eco wicks at ₹5.90 (C1) and ₹9.44 (C2):
| Oil | 50 g | Approval test | 1 kg bought untested | 1 kg as a multiple of the test |
|---|---|---|---|---|
| Mango Coconut | ₹250.00 | ₹764.50 | ₹3,964.00 | 5.2× |
| Honeydew Melon | ₹217.12 | ₹731.62 | ₹3,398.40 | 4.6× |
| Autumn | ₹271.40 | ₹785.90 | ₹5,428.00 | 6.9× |
| Gilli Mitti | ₹448.00 | ₹962.50 | ₹8,960.00 | 9.3× |
Adding the shelf candle adds one more candle's wax, jar and wick: ₹684.82 of consumables instead of ₹514.50. Honeydew Melon is not a pick card here but is in the chart as a second low-cost fruity oil: like Mango Coconut, its page states no candle load, and its 100 g (₹4.35 per gram) costs slightly more per gram than its 50 g (₹4.34). Figures exclude labour, freight, packaging and GST; jars can be cleaned and reused after the test.
Approving four oils at once
If you are adding several oils, pour them in one melt with one shared reference candle. Four new oils need nine candles instead of twelve: two per new oil and one R. With Mango Coconut, Honeydew Melon, Autumn and Gilli Mitti, the four 50 g bottles cost ₹1,186.52, the nine candles' wax, jars and wicks ₹1,547.05, a total of ₹2,733.57, or ₹683.39 per oil approved. Sharing the reference saves ₹510.96 in wax, jars and wicks over four separate tests. The same four oils bought as 1 kg each, untested, would be ₹21,750.40.
What to buy: 50 g samples and test jars
Three oils that each make a different approval point, and the jar our worked examples assume. The oils are not a recommendation to stock; they illustrate a wide page window capped by the wax, a high per-gram exposure, and a page that states no candle load. Chosen on stated load, notes, per-gram pricing and stock at every size on 25 September 2026, not on throw, which CSI has not measured. Candle counts assume 150 g at 8%.

New scents for Christmas, 25 December 2026
Christmas falls on 25 December 2026, 91 days after these prices were checked, and warm, spiced and earthy scents like the ones above suit a winter range (winter runs roughly December to February; colder in the north, milder in the south). Every new scent needs its 14-day approval before production, and a failed one needs time for a second candidate. Working back: production pours by late November need approvals finished by early November, which means new 50 g samples ordered in early October. If you are approving several oils, pour them together in one melt with one shared reference. Once an oil passes, oil per 8% candle at the 1 kg price is ₹65.14 for Autumn, ₹107.52 for Gilli Mitti and ₹47.57 for Mango Coconut; Gilli Mitti's 1 kg is 2.3 times Mango Coconut's, which belongs in the SKU's price. Dispatch times depend on your location; confirm on WhatsApp before you promise a customer a date.
CandleMakingSuppliesIndia sells the fragrance oils and jars named here, and does not sell finished candles. This page tells you to approve every new oil, ours included, before buying more than 50 g, and never to treat our page wording as test data. That is deliberate: an approved oil gets reordered; an untested kilogram gets regretted.
Every price and per-gram figure was verified on CSI's live store on 25 September 2026; every size shown on the pick cards is in stock on that date, and any that was not would be flagged as out of stock. Load windows, notes, IFRA wording and throw wording are quoted from product pages as the pages' claims; where a page states no candle load, we say so. Reviews are quoted as published.
The minimum test design, the pass criteria, the "what counts as new" table and the failed-approval readings are editorial judgement; CSI has no measured throw, stability or colour data for any oil.
