My Oud Fragrance Is Expensive and Performs Strongly at 6% — Is There Any Reason to Push It to 8% or 10% If Lower Loading Already Works?

Start from the fact that 6% already works

It is worth being precise about what performs strongly means, because the rest of this page depends on it. A good 6% result is one where the candle has had the full stated cure, the wick gives a clean pool to the wall, and several people in a closed room agree that the scent is clearly present at a reasonable distance across the burn. If your 6% candle has passed that kind of test, you are not guessing. You have a working formula.

The question then becomes commercial, not technical. You can almost certainly make the candle stronger with more oil, because oud pages give headroom. CSI Woody Oud states 6–10% in soy and 6–8% in paraffin. CSI Royal Oud's page says to start testing at 6–8% and work up, to a maximum of 10% in soy or paraffin. White Royal Oud and Dark Vanilla Oud both state 6–10%. The real question is whether stronger is better for your product, and whether it is worth the money.

One caution on timing. Royal Oud's page states a 72–96 h cure because oud takes longer to express. If you judged 6% before that point, test it again. An oud that seemed adequate at 48 h can open up noticeably later, which strengthens the case for staying low.

The rupee cost of each extra point

Using the series convention for a 200 g candle: 6% is 188 g wax + 12 g oil, 8% is 184 g + 16 g, and 10% is 180 g + 20 g. Per-gram prices come from each oil's 1 kg price: Woody Oud ₹4,531.20 ÷ 1000 = ₹4.5312, Royal Oud ₹6,400.00 ÷ 1000 = ₹6.40, White Royal Oud ₹8,103.00 ÷ 1000 = ₹8.103.

Scale that to a production run. The step from 6% to 10% adds 8 g of oil per candle, so 800 g per 100 candles. For Woody Oud that is 800 × ₹4.5312 = ₹3,624.96. For Royal Oud it is 800 × ₹6.40 = ₹5,120.00. For White Royal Oud it is 800 × ₹8.103 = ₹6,482.40. Every 100 candles.

There is a small offset. Each extra gram of oil replaces a gram of wax, so at 10% you use 8 g less wax per candle than at 6%. With CSI 464 at ₹507.40 per kg, that is 8 × ₹0.5074 = ₹4.06 back per candle. For Woody Oud the net extra is ₹36.25 − ₹4.06 = ₹32.19 per candle. The offset is real but small; it does not change the conclusion.

What it does to the purchase order

Load also changes how far each bottle goes, which matters for cash flow when the oil is expensive. One kilogram of oud fills 1,000 ÷ 12 = 83 whole candles at 6%, 1,000 ÷ 16 = 62 at 8%, and 1,000 ÷ 20 = 50 at 10%.

At 6% the run needs one 1 kg pack and one 500 g pack. At either 8% or 10% it needs two 1 kg packs, an extra ₹9,062.40 − ₹6,796.80 = ₹2,265.60 in cash tied up before a single candle is sold. For Royal Oud, note that the 100 g pack was out of stock on the pull, so small top-ups for testing come from the 500 g pack at ₹3,300.00 (₹3,300.00 ÷ 500 = ₹6.60 per gram) rather than the 1 kg rate.

The legitimate reasons to push higher

There are situations where 8% or 10% is the right answer even though 6% works in your test jar. Each one is specific and testable.

A larger vessel or a bigger room brief. If the same oud is going into a wider jar or is being sold for large living spaces, the 6% result from a 200 g jar does not automatically transfer. Test the new format on its own terms.

Throw that fades late in the candle. Some makers find a candle strong in its first burns and weaker in the last third. If your logs show that, a modest step up, or a wick review, may be justified. Burn a test candle all the way down before assuming it.

Character, not strength. In blends, load can change which notes lead. If your oud reads as mostly spice or citrus at 6% and the dark woods only arrive at 8%, the higher load is buying the scent you are actually selling.

Customer feedback you can verify. If repeated, specific feedback says the candle is too quiet, and your own panel agrees, act on it. Anecdote alone is not enough.

What 10% can cost beyond the rupees

More oil changes the fuel, so the wick that was right at 6% may not be right at 10%. Heavier oud material travelling up the wick can increase carbon on the tip, and an overloaded candle can leave oil unbound in the wax, which shows as sweating or a greasy surface. As a general principle, overloading can also make a candle smell muddier rather than stronger, because the heavier notes crowd out the brighter opening.

A different oud can be cheaper than more oud

If the argument for 10% is really about richness rather than volume, compare oils before you compare loads. Woody Oud at 10% costs ₹90.62 of oil per 200 g candle. Royal Oud at 6% costs ₹76.80, which is ₹90.62 − ₹76.80 = ₹13.82 less, and it is a perfume-grade concentrate with a heart of oud, rose and cedarwood over sandalwood, ambergris and musk. A lower load of a denser oil may give you the depth you are after with less fuel for the wick to handle.

That is not a promise that Royal Oud will outperform Woody Oud in your jar. The two have different structures, and Woody Oud's citrus and spice top gives it a brighter opening that some ranges need. It is a reason to put a 6% Royal Oud candle into the same blind test as a 10% Woody Oud before you order two kilograms of either. The test costs a handful of candles; the wrong bulk order costs thousands.
