If 6% Fragrance Gives Strong Hot Throw and Excellent Stability, Is There Any Reason to Force the Formula to 10%?
शेयर करना
How much does 10% cost over 6%? With Woody Oud at the 1 kg rate, 20 × ₹4.5312 = ₹90.62 versus 12 × ₹4.5312 = ₹54.37, so ₹36.25 more per 200 g candle.
Is 10% within the CSI 464 page figure? 10% of total weight is 11.11% of wax weight, above CSI 464's stated up to 10%, which is itself a ceiling and not a target.
When is a higher load worth testing? When a wider jar, a fading citrus top note or repeated blind-test misses show a real gap. Even then, check wick and melt pool first.
The short answer: usually not
If your 6% candle fills the room on a blind burn, holds a clean surface through your observation schedule and survives your warm-storage check, then pushing it to 10% is a solution looking for a problem. You would be adding two-thirds more oil to fix nothing, while moving the formula closer to the zone where sweating, a drowning wick and soot become likely.
There are a few situations where a higher load deserves a test. None of them justify forcing it. The difference matters: a test can fail and leave you at 6% with better evidence, while forcing means you have decided the answer before the candles have spoken.
What forcing 10% would actually change
Take a 200 g candle with Woody Oud as the example oil. At 6% of total weight the candle holds 188 g of wax and 12 g of oil. At 10% it holds 180 g of wax and 20 g of oil. Here is what moves when you make that change:
| What changes | At 6% of total | At 10% of total |
|---|---|---|
| Oil in the candle | 12 g | 20 g |
| Oil cost at the 1 kg rate | 12 × ₹4.5312 = ₹54.37 | 20 × ₹4.5312 = ₹90.62 |
| Wax-basis equivalent | 6 ÷ 94 = 6.38% of wax | 10 ÷ 90 = 11.11% of wax |
| Against CSI 464's stated up to 10% of wax | Well inside | Above the stated figure |
| Wick behaviour | Your tested, approved wick | Must be re-tested; more oil can change flame and pool |
| Sweat and storage risk | Proven clean in your tests | Unknown until tested |
| Hot throw | Strong on your blind burn | Unknown; may be no stronger |
The per-gram figure comes from Woody Oud's 1 kg price of ₹4,531.20, so ₹4,531.20 ÷ 1,000 = ₹4.5312. The difference per candle is ₹90.62 − ₹54.37 = ₹36.25. On a production run of 500 candles, which is an example quantity rather than anything you have told us, that is 500 × ₹36.25 = ₹18,125.00 of extra oil for a candle you already liked.
Notice the third row. Your 10% of total is 11.11% of wax weight, which is above the CSI 464 page's stated up to 10%. That page figure is a ceiling for typical oils, not a target and not a promise. Going past it with a formula that was already working is the opposite of a careful change.
The few honest reasons to test a higher load
A higher load is worth a controlled trial only when a real gap shows up in testing. These are the ones we would take seriously:
A wider jar or bigger room is coming
If you are moving the same scent into a wider vessel or selling it for larger spaces, the 6% result in your current jar does not automatically transfer. But the first fix to test is the wick and the melt pool in the new jar, not the oil. A fuller melt pool often gives you the extra throw that a higher load was meant to buy.
A volatile top note fades after cure
Citrus families can fade faster than warm notes. CSI's Citrus Lemon page itself suggests curing fully and using the upper end of the range. If a blind burn after a longer cure shows your 6% citrus falling flat, a step to 7% or 8% is a reasonable test. That is a different situation from a woody or amber oil that is already strong.
Blind testers consistently miss it
If several people, smelling coded candles in similar rooms, repeatedly rate the 6% candle as faint compared with your target, that is evidence. A single impression from the person who made the candle is not.
If you do test upward, do it like this
Treat the higher load as a challenger to your approved 6% formula, never as a replacement until it wins on every count.
Ways to get more throw that do not involve more oil
If a test shows the 6% candle genuinely needs more presence, there are cheaper and safer levers to pull before load. Each of them is a formula change that needs testing, but none of them pushes you towards the sweat line.
Give the cure more time
Woody Oud's page states a cure of 48–72 hours in soy before burn testing. That is a minimum, not a finish line. Smell the same candles again at later points such as day 7 and day 14; woody and resinous notes often open up with time, and a candle judged on day three may simply not have arrived yet.
Get the melt pool right
Throw comes from the melt pool. If the pool is shallow or does not reach the edge within a reasonable burn, the candle is releasing less oil than it holds. A wick test in the same jar, with your 6% formula unchanged, may do more for strength than any load increase.
Match the candle to the room
A 200 g jar is a small source of scent. If customers want it to fill a large living room, the honest answer may be a larger candle or a second wick, not a heavier dose of oil in the same small vessel.
Decision: when 6% is already the answer
Lock 6% as both target and maximum on your batch sheet if all four of these are true: the blind burn calls it strong, the surfaces stay dry through your schedule, the warm hold leaves no oily film, and the wick burns cleanly to a full pool. Then spend your effort elsewhere: on process records, on storage conditions and on getting the same result batch after batch.
If one of the valid reasons above applies, run the challenger trial and let the candles decide. If the higher load wins narrowly but costs ₹36.25 more per candle, you may still choose 6%, and that is a perfectly good commercial decision.
What you should not do is raise the load quietly on the production floor because a batch “seems weak”. That is how a stable formula becomes a sweating one. A load change is a formula change and goes through the same testing as any new formula.

CANDLEMAKINGSUPPLIESINDIA supplies raw materials and production equipment, not finished candles. This guide separates general formulation practice from what CSI's own product pages state, converts the pages' wax-weight loads to the total-weight basis used here, says plainly where CSI publishes no figure (wax heat resistance, survival temperatures, oil composition beyond the page), and labels every load step, test temperature, observation day or reject rate as a starting point for your own validation.
Prices are live CSI prices from October 2026; product pages are authoritative. Where a spec is not published — such as the temperature at which a wax starts to release oil — this guide says so rather than filling the gap.

Assumptions: Fragrance load is a percentage of total candle weight (200 g = 184 g wax + 16 g oil at 8%); CSI wax pages phrase their ceilings as a share of wax weight. CSI wax pages state fragrance loads as a share of wax weight; converted here to total weight with W ÷ (100 + W) (10% of wax = 9.09% of the candle; 13% = 11.50%). A stated maximum is the wax maker's ceiling for typical oils, not a promise for every oil. CSI publishes no wax heat-resistance or survival temperature; every test temperature, observation day, load step, reject rate and labour or energy cost is a suggested starting point or the reader's own figure. Blends with microcrystalline wax, Vybar, paraffin or Soy Pillar Wax are the maker's own to test. Wax prices re-checked 7 October 2026, oil prices 1 October 2026; product pages are authoritative.
