What Should I Test Before Buying 1 Kg of a New Candle Fragrance Oil?
Share
What sample should I test with? 100 g. It covers six gate candles (a 6/8/10% ladder, a wick check and a light/dark pair: 72 g at 8% for the last three) and leaves 28 g for a rematch.
What does it cost? For British Rose: ₹495.60 in new materials (100 g plus a C1 and a C2 wick pack), about three weeks from pour, against ₹3,068.00 for the kilogram.
Is 1 kg always cheaper per gram? No. British Rose saves at every step; Pumpkin Spice saves nothing until 1 kg; Woody Oud is flat from 100 g; Sage and Cedarwood's 1 kg is dearer per gram than its 500 g; Vetiver's 1 kg is out of stock on 25 September 2026.

The 1 kg gate, gate by gate
The gate exists because a kilogram changes the stakes. At 8% in a 150 g candle, 1 kg of oil makes 83 candles; at 6%, 111; at 10%, 66. A problem you might shrug off in one test candle, a slight yellow tint, a faint oily sheen after a hot week, becomes 83 problems. So the question is not "do I like this oil?" but "will I be happy to make 83 candles with it, and can I buy the next kilogram?"
| Gate | Pass looks like | Evidence from the six candles | If it fails |
|---|---|---|---|
| 1. Hot throw | At least as good as your current standard candle, scored blind in your usual test room | Ladder candles at day 14 | Check gates 2 and 3 first; then consider a different oil |
| 2. Cure | You know the day it reaches its throw (day 7 or 14) and can plan stock around it | Ladder scored at day 3, 7 and 14 | Wait; judging early is not a fail |
| 3. Wick | Full pool by hour 3 to 4, no soot, no tall flame, with a wick you stock | Ladder (your wick) vs the C2 candle | Change wick, retest; not an oil fail |
| 4. Colour | Acceptable in your sales vessel after 14 days in daylight | Light/dark pair | Tinted vessel, dyed wax or a different oil |
| 5. Sweating | No oily beads or wet film on any candle | All six, especially the 10% | Lower the load within the range; retest |
| 6. Two-week stability | No separation, pooling or mottling you would not sell | Light/dark pair and ladder at day 14 | Load or process first; then the oil |
| 7. Cost per candle | Oil cost at the 1 kg price fits your margin | Arithmetic, not a candle | Lower load if gate 1 allows; or a cheaper oil |
| 8. Stock and pack | 1 kg in stock today, and cheaper per gram than 500 g for this oil | The product page on the day you order | Buy 2 × 500 g, or wait for restock |
Gates 1 to 3: performance
Hot throw is judged against a standard you already trust, not in the abstract: your current standard candle, or a control oil, burned in the same room. How to run the burn itself, room size, check-in times and a blind panel, is in How to Test Fragrance Oil Hot Throw Before Buying It in Bulk; the gate only needs the verdict. Cure matters because soy commonly throws more at day 14 than at day 3; several CSI oil pages state a 48–72 hour minimum for soy (Sage and Cedarwood and Vetiver among them), and many makers score at day 3, 7 and 14 as practice, not rule. If British Rose, which states no cure, only reaches its throw at day 14, that is not a fail; it is a production fact your stock plan must absorb. Wick is a gate because a kilogram of oil needs a wick you can buy in hundreds. The C2 candle tells you whether the next size up is needed at your chosen load.
Gates 4 to 6: appearance and stability
Colour: vanillin and some other aromatic materials commonly cause yellowing or browning over time, faster in light. Oils with vanilla-type bases, such as Pumpkin Spice's "Vanilla Bean, Caramelized Sugar", deserve the light/dark pair; so does any oil whose page states nothing about vanillin. A page stating 0% vanillin (Citronella, Sage and Cedarwood, Vetiver) is a claim, and vanillin is one cause, not the only one; run the pair anyway. The discolouration test proper is in How to Test Fragrance Oil for Discoloration Before Bulk Production. Sweating: past what the wax holds, extra oil tends to sweat or pool; the 10% candle is your early warning. Stability: at day 14 look for oily patches, separation or mottling. A full two-to-three-week stability protocol with a warm-storage check belongs to How to Test Fragrance Oil Compatibility Before Buying 1 Kg or 5 Kg; the gate asks only whether the candles you have look saleable at two weeks.
One 100 g bottle, six candles: the evidence plan
Six candles cover all eight gates because each candle does more than one job. The ladder answers hot throw, cure, sweating and the first wick question; the C2 candle finishes the wick question; the light/dark pair answers colour and stability. How many test candles you need in general, with repeats, is the subject of How Many Test Candles Should I Make Before Buying Fragrance Oil in Bulk?; this is the minimum that feeds this particular gate.
| Candle | Load | Oil | Wax | Wick | Stored | Gates it answers |
|---|---|---|---|---|---|---|
| 1 | 6% | 9 g | 141 g | C1 (your usual) | dark shelf | 1, 2, 3, 5 |
| 2 | 8% | 12 g | 138 g | C1 | dark shelf | 1, 2, 3, 5 |
| 3 | 10% | 15 g | 135 g | C1 | dark shelf | 1, 2, 3, 5, 6 |
| 4 | 8% | 12 g | 138 g | C2 | dark shelf | 3 |
| 5 | 8% | 12 g | 138 g | C1 | daylight, not direct sun | 4, 5, 6 |
| 6 | 8% | 12 g | 138 g | C1 | dark cupboard | 4, 5, 6 |
| Total | 72 g | 828 g | 5 C1 + 1 C2 | all eight with the arithmetic |
The plan assumes 8% as the working load for candles 4 to 6, because it sits in the middle of every range here. If you already know you will produce at 6% or 10%, pour those three at that load instead: at 10% they need 45 g, and the whole plan 81 g, still inside the 100 g bottle with 19 g spare. Candles 5 and 6 are not burned until day 14; you look at them first, then burn them to check that the daylight candle still throws.
| Item | Used | New spend | Value consumed |
|---|---|---|---|
| British Rose 100 g | 72 g | ₹342.20 | ₹246.38 |
| Eco C1 + Eco C2, pack of 10 each | 5 C1 + 1 C2 | ₹153.40 | ₹38.94 |
| Your wax, valued as CSI 464 at ₹0.51/g | 828 g | already owned | ₹420.13 |
| Your jars, valued as the 150 g clear jar at ₹94.40 | 6 | already owned | ₹566.40 |
| Total | 6 candles | ₹495.60 | ₹1,271.85 |
The kilogram costs 9.0 times the 100 g test bottle. All figures exclude labour, freight, packaging and GST.
A failed gate is not always a failed oil
Four of the eight gates can fail for reasons that have nothing to do with the bottle. Hot throw fails when the candle is young, the pool is short of the glass or the room is too large; fix those and rescore. Wick is a wick problem by definition. Sweating at 10% but not at 8% is a load finding, not a reason to reject; produce at 8%. Stability problems often trace to add temperature or cooling rather than the oil. The order to check those in is set out in My Candle Smells Weak When Burning — Do I Need a Stronger Fragrance Oil?.
The gates that genuinely convict an oil are fewer: hot throw that stays weak with a full pool at day 14 when your standard candle throws in the same room; colour you cannot live with in any vessel you would use; and cost or stock that does not work. Those are real rejections, and the gate did its job.
Gates 7 and 8: what 1 kg really saves
Gate 7 asks whether the oil fits your margin at the price you will pay in production, and gate 8 asks whether the kilogram is the right pack to pay it in. Both are arithmetic, and both surprise people. The chart above shows oil per candle at each pack size for seven CSI oils; the table below gives the per-gram savings behind it.
| Oil | 100 g per candle | 500 g per candle | 1 kg per candle | What 1 kg saves |
|---|---|---|---|---|
| British Rose | ₹41.06 | ₹38.23 | ₹36.82 | 10.3% per gram vs 100 g; 3.7% vs 500 g |
| Roasted Coffee | ₹46.80 | ₹45.36 | ₹44.86 | 4.2% vs 100 g; small vs 500 g |
| Woody Oud | ₹54.37 | ₹54.37 | ₹54.37 | Nothing past 100 g; two 500 g equal one 1 kg |
| Pumpkin Spice | ₹70.80 | ₹70.80 | ₹63.72 | 10.0%, and only at 1 kg; 500 g saves nothing over 100 g |
| Citronella | ₹92.04 | ₹35.40 | ₹34.69 | 62.3% vs 100 g, but only 2.0% vs 500 g |
| Sage and Cedarwood | ₹83.54 | ₹62.02 | ₹82.41 | Costs 32.9% more per gram than 500 g: buy 2 × 500 g |
| Vetiver | ₹72.00 | ₹69.60 | Out of stock | 1 kg out of stock on 25 September 2026; 500 g is 3.3% below 100 g |
What the saving is worth across a kilogram
Across the 83 candles a kilogram makes at 8%, British Rose at the 1 kg price saves ₹352.58 compared with paying the 100 g per-gram price for the same oil, and ₹117.53 compared with the 500 g price. Pumpkin Spice saves ₹587.64 against the 500 g price. Those savings are real, but they are small next to what a failed kilogram costs, which is the whole ₹3,068.00 or ₹5,310.00.
Cost per candle, the whole candle
Gate 7 should use the whole candle, not just the oil. Worked example: one British Rose candle at 8%, oil at the 1 kg price (₹36.82), 138 g of CSI 464 (₹70.02), a 150 g clear jar (₹94.40) and a C1 wick (₹5.90) comes to ₹207.14; the oil is about 18% of it. The same candle in Pumpkin Spice at the 1 kg price with a C2 wick is ₹237.58. Both exclude labour, freight, packaging and GST. At 6% British Rose oil drops to ₹27.61 a candle; at 10% it rises to ₹46.02. If gate 1 passed at 8%, there is no reason to pay for 10%.
Five oils, five lessons at the gate
Each of these oils illustrates a different gate: a clean saving at every step, a saving that only arrives at 1 kg, a test bottle that misleads on cost, a kilogram that costs more per gram than 500 g, and a kilogram you cannot buy today. All five state a 10% maximum for candles or soy. Chosen on page statements, pack pricing and stock on 25 September 2026, not on throw, which CSI has not measured. Candle counts assume 150 g at 8%.

Beyond 1 kg, the next gate adds a repeat batch, second-order consistency and storage; CSI's largest listed oil size is 1 kg, so 5 kg is several kilograms or a WhatsApp quote. That is What Tests Should I Run Before Ordering 5 Kg of a Candle Fragrance Oil?.
Timing the kilogram for Valentine's Day
Valentine's Day falls on 14 February 2027, in the middle of winter, roughly December to February, and rose ranges are the obvious use for British Rose. The gate takes about three weeks, because its last burn round starts at day 14, and a production batch wants at least another fourteen of cure before it ships. Working back: pour the gate candles by 1 December 2026, finish the day-14 round by 20 December, order the kilogram before Christmas (25 December) to avoid holiday dispatch delays, and pour production by 8 January. Confirm dispatch time to your city on WhatsApp before you promise dates.
| By | Do this | Spend |
|---|---|---|
| 25 November 2026 | Order British Rose 100 g and the C1/C2 packs | ₹495.60 |
| 1 December 2026 | Pour the six gate candles | nothing new |
| 15–20 December 2026 | Day-14 round (six evenings); do the arithmetic | nothing new |
| 21 December 2026 | If all eight pass, order 1 kg with GST invoice | ₹3,068.00 |
| 8 January 2027 | Pour production (83 candles at 8% from the kilogram) | wax, jars, wicks |
| 22 January 2027 | Production day 14: spot-burn one, then dispatch | |
| 14 February 2027 | Valentine's Day |
CandleMakingSuppliesIndia sells every 1 kg in this post that is in stock, and does not sell finished candles. This page tells you not to buy them yet, points out where our 500 g beats our 1 kg on price, and flags a kilogram we cannot sell you today. A buyer who passes the gate reorders; a buyer who regrets a kilogram does not.
Every price and per-gram figure was verified on CSI's live store on 25 September 2026; the one pack in our tables that is not in stock (Vetiver 1 kg) is flagged as out of stock. Notes, loads, cures, vanillin statements and throw wording are quoted from product pages and are the pages' claims.
The eight gates, their pass criteria, the six-candle plan and the dated plan are editorial judgement; CSI has no measured throw, colour or stability data for any oil. For bulk pricing, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.
