My Lavender Candle Performs Well at 8% but My Vanilla Candle Does Not — Should I Optimise Fragrance Load Separately for Every Fragrance?
Share
Why might vanilla be weaker than lavender at the same load? Vanilla-type profiles are commonly described as base-heavy and slower to project than bright herbal ones, and they can change how the pool and wick behave. Those are general mechanisms, not measurements of any CSI oil. Details below.
How high can I take vanilla in CSI 464? To 10%, the wax maker's stated maximum for Luxury Soy Wax CSI 464. That is 20 g in a 200 g candle. If vanilla still fails at 10%, more oil is not available to you in that wax. Luxury Soy Wax Chunks are rated up to 13%.
What does a proper test cost? About ₹2,418.80: 100 g of Vanilla Bean, 1.5 kg of CSI 464 (1 kg + 500 g), ten Thin C1 and ten Thick C2 wicks, and ten jars. See the 2 × 2 test.
Why vanilla can lag behind lavender
We have no composition data for any CSI oil, and we do not publish throw measurements, so nothing here says how Vanilla Bean or Lavender will behave in your candle. What we can do is describe the mechanisms candle makers and perfumers commonly point to when a sweet, gourmand scent under-performs next to a herbal one at the same load.
| Factor | Herbal profiles (lavender-type) | Sweet gourmand profiles (vanilla-type) | What to check |
|---|---|---|---|
| Volatility | Commonly described as rich in lighter, brighter materials that leave a warm pool readily | Commonly described as base-heavy: sweet, dense materials that release more slowly | Judge vanilla after a longer burn, not in the first half hour |
| Perceived intensity | Sharp, recognisable, easy to notice across a room | Soft and rounded; easy to underrate, and easy to stop noticing | Blind comparison at a fixed distance and time |
| Effect on burn | Often associated with a free-flowing pool | Heavier oils can change how the pool feeds the wick | Time to full melt pool; flame height; carbon on the wick |
| Cure | Many makers find fresh profiles smell ready early | Many makers find gourmands keep developing through the cure | Compare at the same cure age, e.g. 14 days |
| Colour | Rarely a concern in general practice | Vanilla-type materials are commonly associated with wax darkening over time | Not a strength problem, but note it; My Custom Blend Performs Well at 8% but One Component Discolours the Wax — How Do I Identify Which Fragrance Is Causing It? covers diagnosis |
Read the table as a list of suspects, not a verdict. Several of those factors point to a problem that more oil will not fix. If the vanilla candle's pool reaches the glass an hour later than the lavender's, the vanilla has been releasing less for that hour at any load. If you judged both in the first thirty minutes, you judged the herbal oil at its brightest and the gourmand before it had opened. Why vanilla turns flat and overly sweet in hot wax goes into the scent-shape side of the problem; this page stays on load.
Diagnose before you dose
The three checks below take almost no money. Each one either points to a cheaper fix or clears the way for a fair load test. Do them in this order, because each check depends on the one before it.
The 2 × 2 test: load versus wick
A 2 × 2 test crosses two loads with two wicks: four candles, each differing from its neighbours in only one thing. Add one lavender candle at 8% with your current wick as a reference, and one vanilla at 9% if you have oil left. Everything else is fixed: CSI 464, the same jar, 200 g fills, the same addition method and the same cure.
| Code | Scent | Load | Oil + wax | Wick | What it tells you |
|---|---|---|---|---|---|
| A | Vanilla Bean | 8% | 16 g + 184 g | Current (e.g. Eco Thin C1) | Your baseline |
| B | Vanilla Bean | 10% | 20 g + 180 g | Current | Does oil alone fix it? |
| C | Vanilla Bean | 8% | 16 g + 184 g | One step up (e.g. Eco Thick C2) | Does wick alone fix it? |
| D | Vanilla Bean | 10% | 20 g + 180 g | One step up | Do both together fix it — and does the burn stay clean? |
| E | Vanilla Bean | 9% | 18 g + 182 g | Whichever wick wins | Can you pass below the ceiling? |
| R | Lavender | 8% | 16 g + 184 g | Current | Reference — what "passing" smells like |
Reading the results is straightforward. If C passes and B does not, the wick was the problem and the vanilla can stay at 8%, which is the cheapest outcome. If B passes and C does not, the vanilla genuinely needs more oil. If only D passes, it needs both; watch that the bigger wick and higher load together do not produce soot, a mushroomed wick or a pool that gets too hot. If nothing passes, the vanilla is not going to work at any load this wax allows — see the next section. Whether the Thick C2 is actually the right "one step up" for your jar is something only a burn test can tell you; treat it as an example of a larger wick, not a recommendation.
| Item | Quantity | Price | Line total |
|---|---|---|---|
| Vanilla Bean Fragrance Oil 100 g | 1 | ₹790.00 | ₹790.00 |
| Luxury Soy Wax CSI 464 1 kg | 1 | ₹507.40 | ₹507.40 |
| Luxury Soy Wax CSI 464 500 g | 1 | ₹260.00 | ₹260.00 |
| Eco Candle Wicks Thin C1 (10) | 1 pack | ₹59.00 | ₹59.00 |
| Eco Candle Wicks Thick C2 (10) | 1 pack | ₹94.40 | ₹94.40 |
| White Matte Glass Jar (pack of 5) | 2 packs | ₹354.00 | ₹708.00 |
| Total | 6 candles + spares | ₹2,418.80 |
The six candles use 1,094 g of wax, so 1 kg is not quite enough; the extra 500 g pack brings you to 1,500 g and leaves about 406 g for a repeat of the winning candle (a 4% pour-loss allowance is a sensible working assumption). You probably already have lavender from production; the reference candle needs 16 g of it. The vanilla bottle is used almost exactly: 72 g in the four grid candles plus 18 g in candle E leaves 10 g.
When the wax ceiling stops you
In Luxury Soy Wax CSI 464, the wax maker's stated maximum is 10%. That is a formulation limit, not a regulatory one, and not a recommended dose — but it is the top of your ladder. If the vanilla fails at 10% with the best wick your burn tests allow, there are three honest exits.
| Exit | What changes | Cost impact per 200 g candle | Watch for |
|---|---|---|---|
| Move the vanilla to Luxury Soy Wax Chunks | Wax rated up to 13%, so you can ladder to 11% and 12% | Chunks ₹0.60/g vs CSI 464 ₹0.51/g; at 12% oil rises to ₹189.60 | Two waxes in production; a new wick test in the new wax |
| Switch to a different vanilla oil | Same wax and load; different formula | Dark Vanilla is the same price; Cinnamon Vanilla is ₹4.84/g at 100 g | Scent profile changes; re-test from 8% |
| Accept a softer vanilla | Keep 10% and sell it as a gentle scent | No change | Honest labelling; customers expecting a room-filler will be disappointed |
Moving one scent to a different wax sounds disruptive, and in a small workshop it can be. But it is often cheaper than it looks: you already buy wax by the kilo, and the Chunks cost ₹599.00 against CSI 464's ₹507.40. Switching oils is the other clean route, and it keeps the production sheet simple. Whatever you choose, re-test from 8%, not from where the old oil ended up. A new oil or a new wax resets the evidence.
What each fix costs
The table below prices the vanilla at each step of the ladder and the two Chunks steps beyond CSI 464's ceiling, next to the lavender that is already passing. Material cost here means oil, wax, a ₹5.90 Eco Thin C1 wick and a ₹70.80 White Matte Glass Jar. It excludes labour, packaging, freight and GST.
| Scent and wax | Load | Oil + wax | Oil cost | Material cost |
|---|---|---|---|---|
| Lavender (passes at 8% in this example) | 8% | 16 g + 184 g | ₹86.40 | ₹256.46 |
| Vanilla Bean | 8% | 16 g + 184 g | ₹126.40 | ₹296.46 |
| Vanilla Bean | 9% | 18 g + 182 g | ₹142.20 | ₹311.25 |
| Vanilla Bean | 10% | 20 g + 180 g | ₹158.00 | ₹326.03 |
| Vanilla Bean in Luxury Soy Wax Chunks | 11% | 22 g + 178 g | ₹173.80 | ₹357.12 |
| Vanilla Bean in Luxury Soy Wax Chunks | 12% | 24 g + 176 g | ₹189.60 | ₹371.72 |
Each extra point of vanilla adds 2 g of oil, which is ₹15.80 at the 100 g price. Moving from 8% to 10% adds ₹31.60 a candle. Swapping a Thin C1 wick (₹5.90) for a Thick C2 (₹9.44) adds ₹3.54. Across a run of 500 vanilla candles, 2 extra points of oil at the 1 kg rate (₹7,646.00 / kg) cost ₹15,292.00; the wick upgrade costs ₹1,770.00. If the 2 × 2 test says the wick alone fixes it, that difference is the value of running the test.
Vanilla Bean is also one of the few places where scent price makes the load decision sharper. At ₹7.90 a gram at 100 g it costs noticeably more than lavender at ₹5.40, so every unnecessary point of load is expensive. Finding the lowest load that still throws and the 7% vs 10% test for expensive oils take that logic further.

| 15 g | ₹130.00 | ₹8.67 | 0.75 |

Once the vanilla has a tested load, write it on the production sheet as its own line — scent, load, grams of oil, grams of wax, wick — and colour-code it so it cannot be poured at the lavender's 8% by mistake. If more scents turn out to need their own loads, the per-scent grid shows how to group them into a standard and a lifted load. When you are ready to order, the bulk-dosage guide turns each tested load into kilograms.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. We would sell more oil if we told you to raise every scent to 10%, or to buy a second vanilla. This page puts the cheaper checks first — wick, cure and blind judging — because they are more often the answer.
Oil and wax prices come from live CSI listings pulled on 24 September 2026. Eco Candle Wick prices are from the 25 September pull (Thin C1 10 for ₹59.00; Thick C2 10 for ₹94.40, back in stock).

Mechanisms described for herbal and vanilla-type profiles are general candle-making knowledge, not CSI measurements; we have no composition, throw or dosage data for any oil. The 7- and 14-day cure checkpoints, the choice of Thick C2 as an example larger wick and the 500-candle figures are working assumptions.

Non-price figures and assumptions: Load is the share of finished candle weight (oil = total × load); 16 g into 200 g of wax would be 7.41%. The 200 g candle, the 2 × 2 design, Thick C2 as an example larger wick, 7- and 14-day cure checkpoints and the 500-candle comparison are working assumptions. Herbal and vanilla-type behaviour is described from general candle-making knowledge, not CSI measurement. Ceilings of 10% (CSI 464) and 13% (Chunks) are the wax makers' stated formulation maximums, not regulatory limits. Diwali 2026 falls on 8 November.
