Can Reducing Fragrance Load Also Improve Wick Behaviour Enough to Create Additional Savings or Production Consistency?

What a lower load can do to the wick

A wick draws melted wax and fragrance up to the flame. Change what is in the pool and you can change the flame. These are tendencies from candle-making practice, hedged because they vary with wax, oil and jar:

Why a higher load can change flame size is the subject of the 6%-to-10% flame-size post; whether a 10% to 8% cut needs a wick retest at all is the reduced-to-8% wick-retest post (it does need at least a full-life check). This page owns the money: what a changed wick could save, and when you are allowed to count it.

Three BOMs: today, load cut, load cut plus wick

The worked candle: 200 g (series default; use yours) of Roasted Coffee at its 1 kg price in Premium Coconut Soy Wax CSI 468 at the 5 kg price (0.6370 rupees a gram), your own jar and box (labelled worked examples). The CSI 468 page states "Fragrance Load Up to 13%", a pour temperature of 58°C–60°C and "Clean, stable burn with low soot output"; both 10% and 8% are inside its ceiling on either reading (13% of wax weight is 11.50% of total).

A to B is the load cut: ₹12.40 a candle (the per-gram formula gives ₹12.40: 4 g × (oil − wax) per gram). That figure, and how it scales across 1,000 candles, belongs to the 10%-to-8% saving post. B to C is the wick: ₹3.54, which is 29% of the load saving. The wick is 3.5% of the candle; even halving its cost moves COGS by less than the oil already has. That is the honest proportion: the secondary saving is real money at volume, but it is the smaller of the two, and it carries its own test.

The secondary-saving table: banked or possible

How the reject line works: cost per saleable candle = cost per poured candle ÷ (1 − reject rate). On BOM C, 3% rejects gives ₹277.24 per saleable candle; 1.5% would give ₹273.02. The difference, ₹4.22, is what a cleaner burn could be worth, and each percentage point of rejects is worth about ₹2.77 here. For comparison, BOM A at 3% rejects is ₹293.67 per saleable candle and BOM B ₹280.89. Use your own reject records; the 3% and 1.5% are illustrations, not forecasts.

The wick ladder at the new load

Step one costs nothing extra: the load test already burned 8% candles to the end on the current wick (that is part of the load test design). Read that record. If the 8% candles burned like the 10% control, stop; there is no wick saving to chase. If they ran bigger or hotter, run a wick ladder at 8%:

On the wick saving alone that repays in about 1.7 months at 400 candles a month, or 6.8 months at 100 a month (worked volumes); if the hypothetical reject effect also held, in about 0.8 months at 400. Whether a cheaper wick is worth the testing effort in general is the ₹2-cheaper-wick payback post; why the full life matters is the wick-struggles-halfway post. If your jar is wide enough to use Cotton Braided (its page says "exceeding 8 cm"), add three on it (₹36.00) as a third arm.

Consistency: fewer rejects, fewer wick types

Two consistency gains are plausible after a load cut, and both need records, not hopes.

Fewer burn-related rejects

If your QC rejects candles for carbon build-up, soot on the glass or a hot jar, and those were linked to a heavy load on a generous wick, a lower load on the right wick may reduce them. Log rejects by cause (soot, mushrooming, tunnelling, surface, breakage) for two months before and two after the change. Only the burn-related causes belong to this decision. At about ₹2.77 per saleable candle per point of rejects, a one-point fall at 400 a month is worth ₹2.77 × 400 = ₹1,108.00 a month.

Fewer wick types to stock

If several oils were on C2 only because their loads were high, and each passes on C1 at its new load, you might stock one wick type for most of the range. That simplifies buying and reduces the chance of fitting the wrong wick. It is not a per-wick discount: C1 and C2 are flat per wick at every pack, so consolidating saves handling and mistakes, not price. How to standardise wicks without forcing a fragrance onto an unsuitable one is the wick-SKU standardising post, and how to tell whether nearby fragrances can share a wick is the shared-wick post.

A before-and-after record that settles it

Consistency claims fail because nobody wrote down what "before" looked like. Keep one sheet per SKU for two production months before the change and two after, with the same fields every time:

If after two months the burn-related rejects have not moved, the consistency gain was not there, and that is a perfectly good result: you still have the oil saving, and you have stopped guessing.

Where the extra saving is not there

Four situations where you should expect no secondary saving at all. Your wick was never load-limited: the full-life burn at 8% looks like 10%; keep the wick. You are already on C1: CSI lists no smaller sized, tabbed wick, so the step does not exist here (cut-to-length braided rolls are unsized options, not a smaller rung). You use wooden wicks: CSI lists one Performance Wooden Wick with no width options, so there is no narrower wooden wick to step to; ask on WhatsApp if you need one. Your jar needs two wicks: moving from two wicks to one larger wick is a different decision with its own burn risks, covered in the two-wicks-or-one post; two C1 cost ₹11.80 against one C2 at ₹9.44 and one Cotton Braided at ₹12.00, but money comes second to the burn.

And the general limit: the wick is 3.3% of the worked candle's cost. Even the best wick outcome moves COGS by ₹3.54; the oil already moved it by ₹12.40. If you want more than that, the next lever is not the wick: it is per-oil loads across the range (the range-wide per-oil load post) or the jar and packaging.

The wick rungs and the worked candle
