My Fragrance Is Stable at 6% but Sweats at 8% — Is 6% Automatically the Commercial Maximum for That Wax-Fragrance Combination?

Your test found a boundary, not a number

You poured one candle at 6% and one at 8% of total candle weight. The 6% candle stayed dry; the 8% candle beaded oil. That result is genuinely useful, but it does not say that 6% is the ceiling. It says the ceiling for this wax, this oil and this process lies somewhere between 6% and 8%, and that it could sit at 6.2% or at 7.8%. Calling 6% the commercial maximum on that evidence is a guess dressed up as a specification.

There are also two ways the conclusion could be wrong in the other direction. The 8% candle might have sweated because of something other than load, such as oil added to wax that had cooled too far, a short stir, or a cold bench. And the 6% candle might be dry on day four but not on day fourteen, or not after a warm week. Before you write any maximum down, you need to know that the 8% failure repeats and that the 6% pass holds.

So the honest answer to the title is no: 6% is not automatically the commercial maximum. It is the highest load you have proven so far. Whether the approved figure ends up at 6%, 6.5% or 7% depends on a narrower ladder, repeated candles and a margin you choose on purpose.

First, convert both numbers to the wax page's basis

CSI wax pages state fragrance load as a percentage of wax weight. This series works in percentage of total candle weight, so convert before you compare anything with a product page. The formula is W ÷ (100 − W) × 100 to go from total basis to wax basis, and W ÷ (100 + W) × 100 to go the other way.

Your 6% of total is 6 ÷ 94 = 6.38% of wax weight. Your 8% of total is 8 ÷ 92 = 8.70% of wax weight. If your wax is Luxury Soy Wax CSI 464, its page says fragrance load up to 10%, which is a wax-weight figure equal to 9.09% of the candle. Your failing candle is below that stated figure. That is not a contradiction and not a fault in the wax: a stated maximum is the wax maker's ceiling for typical oils, and some oils, some processes and some rooms will meet their limit well below it.

The practical lesson is that the product page gave you an upper fence, and your own test has now drawn a lower, specific fence for this pair. The specific fence wins.

Run a fine ladder between the pass and the fail

To find where the real boundary sits, pour the gap in half-percent steps. In a 200 g candle, each step changes the oil by just 1 g, which is why a scale that reads single grams reliably matters more here than at any other stage.

The oil cost uses Bergamot Amber's 1 kg price of ₹5,437.00, so ₹5,437.00 ÷ 1,000 = ₹5.437 per gram. Swap in your own oil's per-gram price. The rate falls on larger packs, so cost the load you will actually buy for.

Set the commercial maximum one step under the proven ceiling

Suppose the ladder comes back like this: 6% and 6.5% stay dry everywhere, 7% stays dry at room temperature but one of the three beads in the warm hold, and 7.5% and 8% sweat by day 7. Your proven ceiling is 6.5%. Your commercial maximum, the figure you allow on a batch sheet, should normally sit at or one step below it, because production never reproduces a lab pour exactly.

Scale-up adds small errors: a fragrance bottle weighed in a warm room, a 2 g overpour on a big batch, an oil lot that differs slightly from the one you tested. A margin absorbs those errors. Approving 6.5% with no margin means every small mistake lands on the failing side.

Check whether you even need more than 6%

The ladder answers how far you can go. A blind hot-throw comparison answers how far you need to go. Burn the 6% and 6.5% candles side by side in similar rooms, coded so the person smelling does not know which is which. Repeat on a second day. If nobody can reliably pick the stronger one, the extra half percent buys nothing but cost and risk.

Bergamot Amber's own page gives a useful reminder here: it describes 6% as letting bergamot lead, 8% as balanced and 10% as bringing amber, vanilla and musk forward. A load changes character, not only strength, and the version you prefer may not be the highest one. That is a page description, not measured data, so confirm it in your own candles.

The decision rule for this wax-fragrance pair

Use this sequence and you will have a defensible number rather than an assumption:

If the 8% failure does not repeat when the process is controlled, the problem was process, not load, and the ladder needs re-running before you conclude anything. If it repeats, run the half-step ladder. If the highest clean step is 6%, then 6% is your commercial maximum and you approve 6% with no headroom, or 5.5% if you want margin and the throw allows it. If the highest clean step is above 6%, approve a figure one step below it and target whatever load the blind throw test says is enough.

Write the result as a pair-specific rule: this wax, this oil, this jar, this process, maximum X%. It does not transfer to another oil in the same wax, or to the same oil in another wax. Each new pair earns its own ladder.

For the purchase itself, you do not need much. The fifteen-candle ladder above uses 188 + 187 + 186 + 185 + 184 = 930 g of wax per set of five, so three sets need about 2.8 kg; a 5 kg pack of CSI 464 at ₹2,537.00 covers it with spare for the repeat. The oil needed is (12 + 13 + 14 + 15 + 16) × 3 = 210 g, so a 500 g pack of the oil covers the ladder and a repeat.
