I'm Developing a Signature Fragrance for My Candle Brand — Should I Finalise the Fragrance Blend First or Optimise Its Wax and Wick Performance Simultaneously?

The four stages

Stage 0, the system. Some choices are not fragrance decisions at all. The wax type, the jar and the candle size are set by your brand, your price point and your customer. Make them first and freeze them. A signature developed in a 100 g test tin and launched in a 300 g jar is a different candle. For the wick, take the one you already use for this wax and jar as a provisional choice. CSI does not publish wick sizes by diameter, so if you have no wick history for this jar, run a quick unscented or single-oil burn test first to find one that gives a full melt pool.

Stage 1, the blend. With the system frozen and the load fixed at 8%, the only variable is the blend. Pour each oil alone as a reference and the pair at 80/20, 70/30, 60/40 and 50/50. That is 6 candles. Judge blind at the same cure checkpoint and choose one ratio. How many components to start with and why blends must be judged in wax cover the blend decisions themselves.

Stage 2, load and wick. Now the blend is fixed. Pour it at 6%, 8% and 10%, each with two wick options, 6 candles. This is the stage most makers skip, and it is where a good blend becomes a good candle. Finding the lowest load that still throws and reducing fragrance or increasing wick cover the reasoning. Stage 3, confirmation. Pour 2 candles of the winning combination and burn them fully, start to finish, at full cure. Then write the formula down.

All at once vs staged, counted and priced

Every candle below is 200 g in a White Matte Glass Jar (₹70.80), with wax at ₹599.00/kg and the blend priced at 100 g rates: Palo Santo ₹6.02/g and Fallen Leaves ₹4.72/g. Wicks are Eco Thin C1 at ₹5.90, Eco Thick C2 at ₹9.44 and Cotton Braided at ₹12.00. Loads follow CSI's convention: load is a share of the finished weight, so 6%, 8% and 10% of 200 g are 12 g, 16 g and 20 g of oil.

The staged plan costs ₹6,173.56 less in materials than the full matrix, and it answers a better question. The blend-only route is cheapest, at 6 candles, but it launches a candle whose load and wick were chosen before the blend existed. That is the route that produces a lovely signature that tunnels, smokes or goes quiet in the customer's home.

Each two-point step in load moves the candle by about ₹20.12, because oil at ₹5.63/g replaces wax at ₹0.60/g. The wick choice moves it by a few rupees at most. So once the stage-2 panel has spoken, the cost follows almost entirely from the load. How Do I Find the Lowest Fragrance Load That Still Gives Strong Hot Throw so I'm Not Wasting Expensive Fragrance Oil? covers how to find the lowest load that still performs.

Why load and wick are tested together

Load and wick interact. More fragrance oil changes how the wax melts and burns, and a wick that gives a clean, full pool at 6% may flood, smoke or mushroom at 10%. A wick that is right for 10% may leave a narrow pool at 6%. If you fix the wick and vary only the load, you may reject the best load because the wick was wrong for it. That is why stage 2 is a small matrix, three loads by two wicks, rather than two separate lines of tests. Why less fragrance can burn better describes the effect.

The blend, by contrast, can reasonably be chosen at one fixed load and wick, because what you are judging in stage 1 is character, balance and identity, which move less with small burn changes than throw does. It is not perfect: a blend's balance can shift a little at a different load, which is why stage 2 is scored for identity as well as throw, and why the confirmation stage exists. But it is close enough to choose a ratio, and it keeps the number of candles sane.

The calendar, and Diwali

The staged plan takes longer in calendar time than pouring everything at once, because each stage waits for a cure. How much longer depends on the checkpoints you use. Screening decisions (stages 1 and 2) can reasonably be made at a 7-day checkpoint, as long as every candle in the stage is the same age. The confirmation stage should run to your full cure. The 7- and 14-day figures below are working checkpoints, not a CSI cure specification; why curing affects throw and why equal cure age matters explain the reasoning.

Even the faster route reads its confirmation candles on 28 October, only 11 days before Diwali. A festive run poured after that still needs its own cure, packing and shipping, so there is no realistic room for it. That is the honest answer: a brand-new signature developed properly from today is a post-Diwali launch, well timed for the November–February wedding season. For Diwali itself, sell a proven single oil or a blend you have already confirmed, and let the signature arrive when it is ready.

Gates between stages

A stage ends only when it has produced a clear decision. If it has not, repeat it with a better-designed test rather than carrying uncertainty forward, because every later stage builds on it.

Shopping list: the staged plan

Oil use assumes the stage-1 winner is 70/30 (swap the split if yours differs). Palo Santo: 16 g single + 52 g across four 20 g premixes + 67.2 g in stage 2 + 22.4 g in stage 3 = 157.6 g, bought as 100 g + 50 g + 15 g (₹1,008.90; the 500 g would be ₹3,009.00). Fallen Leaves: 82.4 g, inside one 100 g. Wax: 2,576 g across 14 candles, so three 1 kg bags, which also leaves a small margin for the usual 3–5% pour and test-burn allowance (a working assumption).

Without the scale, jug and sticks, the consumables come to ₹4,552.30. The shopping list costs more than the ₹3,875.79 of materials inside the candles because packs come in fixed sizes; the leftover oil becomes your retained samples and the start of your first production batch.
