One Fragrance Needs a Different Wick from Every Other Candle in My Range — Should I Stock That Additional Wick or Reformulate the Fragrance Load?

The two orders on the table

The worked example: a range on Eco C2 in CSI's 150 g Clear Glass Jar ("150g fill capacity"; about 6.3 cm inside on our labelled 0.35 cm wall assumption, 31.17 cm² of pool), poured in CSI 464 at 80–85°C because the jar page's "Safe for hot pour up to 85°C" is lower than the wax page's 80–90°C. Coffee Vanilla Tobacco at 9% (13.5 g oil + 136.5 g wax) ran a large flame with carbon on C2 and passed three full-life candles on C1. Every other oil passed on C2. If your odd one has not yet passed full life on its own wick, that comes first; this page starts after the evidence is in.

Why test 8% as well as 7%: the page's range is 7–9%, and 8% may keep more of the 9% character while still settling on C2. If 8% passes, it saves ₹12.90 of oil a candle against 9% (₹8.60 a candle overall once the wick change is netted off). How to run a load-down retest properly, current wick plus the rung below, is the 10%-to-8% retest post; this page only prices it.

What an extra wick SKU really costs

People treat a new wick SKU as expensive because it feels like complexity. In CSI's range the numbers are small, and in this case they even run the other way: every CVT candle on C1 uses a ₹5.90 wick instead of a ₹9.44 one. The real costs are four, and only one of them is a rupee figure you can write down in advance.

Because C1, C2 and Cotton Braided are flat per wick, there is no volume penalty for splitting your buying across two SKUs: 63 C1 a month cost ₹5.90 each whether you buy them as 50 + 20 or as a 100. The only pack effect is rounding, a few spare wicks in a pack you will open next month. The general case for carrying generous safety stock of cheap, small items is the wicks-versus-oil safety-stock post.

The mirror case is worth a line. If your odd fragrance needs a bigger wick than the house C2 (it tunnels, and Cotton Braided passes), the extra SKU costs ₹2.56 more per candle and the smallest pack is 10 for ₹120.00. The logic is the same, only the per-candle sign flips: still small next to the oil. Ask us if that is your case.

What reformulating the load really costs

Reformulating costs three things. The test bill is known: six candles, ₹1,651.60 including jars. The time is known: cure plus full-life burns before the new load can go on sale, weeks rather than days. The throw is not known, and it is the cost that decides. The page's own wording, "strong throw at lower loads", is a reason to try 7% and 8%; it is not a measurement, and CSI has no throw data for any oil.

Do not assume a lower load simply calms the flame. A lower load can reduce carbon on the wick, and it can also let the flame burn taller, because a heavy oil load is one of the things commonly linked to a smaller, sootier flame. That is why the retest uses C2, the wick you want to stay on, and burns to the bottom rather than stopping at the first good pool. Which lever to pull first when a candle sits between wick and load is the wick-up-or-load-down post; non-wick ways to keep a candle strong are the strength-roadmap post.

The oil alone saves ₹25.80 a candle between A and 7%; the dearer C2 wick and the extra 3 g of wax give back ₹5.06. The wick runs the other way. So if the lower load wins, it wins on oil, and the wick SKU question disappears as a side effect. Argued against our own interest: at 100 CVT candles a month, 7% means ₹2,579.70 of Coffee Vanilla Tobacco a month that you no longer buy from us. We would still rather you ran the load that makes the better candle.

The break-even table, in candles a month

Every figure below is a worked example on the prices above: C1 a month at a 5% allowance, safety stock at half a month (never below one 20-pack), worst-case dead stock as safety stock plus a month of packs, and option B's materials saving of ₹20.73 a candle set against its ₹1,651.60 test bill.

Read it across. Option A's costs barely move: even at 200 candles a month the C1 safety stock is ₹619.50, and that is stock you will use. Option B's saving scales with volume, so the test pays back in about four months at 20 candles a month and inside a month from about 80. That is the whole money case. Throw sits above it: if the 7% candle loses on a blind comparison, none of the right-hand column happens.

Decide in this order

If you go with option A, size C1 from CVT's sales alone. Worked example: 60 CVT candles a month at a 5% allowance is 63 C1 a month, bought as a 50-pack and a 20-pack (₹413.00); at 2.1 a day, a 14-day lead time and half a month of safety stock, reorder at 61 wicks. CSI does not publish lead times or stock depth; confirm dispatch on WhatsApp. Oil for the same month is 810 g at 9% or 630 g at 7%. How the odd SKU fits into the wider range of rungs you stock is the inventory-reference post; reorder points across several sizes are the reorder-point post.

What to buy, and what to skip

Four items, chosen on page statements, price and stock on 1 October 2026. CSI publishes no wick-performance or throw data, so nothing here is ranked on burn results.

Skip for this decision: Cotton Braided Wicks (₹120.00 for 10): a step the wrong way for a fragrance that already burns too hard on C2. Performance Wooden Wicks (₹590.00 for 10): a construction change is a new system test, not a fix for one fragrance. Roasted Coffee as a substitute: a different oil (page: "candles (6-10%)") restarts the approval rather than ending it.
