If I Reduce Fragrance Load From 10% to 8% Across 1,000 × 200 g Candles, How Many Kilograms Less Fragrance Will I Need?

Four kilograms, and where each gram of it comes from

Start from the wax, because the load is a percentage of it. A thousand candles holding 200 g of wax each is 200 kg of wax, and that figure does not change when you move the load. Ten per cent of 200 kg is 20.00 kg of fragrance oil. Eight per cent is 16.00 kg. The difference is 4.00 kg, and it arrives as 4 g removed from each of a thousand candles rather than as a saving you can see in any single one.

That is the whole answer, and it is worth resisting the urge to complicate it. Two percentage points of 200 g is 4 g. Four grams times a thousand is 4,000 g. Four thousand grams is four kilograms. The reason this question gets asked at all is that most makers think in millilitres and bottles rather than in kilograms of a production run, and four kilograms of fragrance oil is a quantity you have to decide to buy weeks before the first candle is poured.

This page carries the reading where 200 g is the wax, so each candle receives 20 g of oil at 10% and holds 220 g of scented wax, or 16 g of oil and 216 g of scented wax at 8%. That is how CSI product pages state loads: Luxury Soy Wax Chunks gives a maximum of 13% of total wax weight, which puts both 10% and 8% comfortably inside it. The Spicy Raspberry page does not publish a candle usage range, so on this pairing the wax's stated maximum is the only published limit — where an oil page does publish a range, the lower of the two governs. Ask on WhatsApp for the documentation on any oil whose page is quiet about load.

Which 200 g you mean, and the 630 grams it moves

"1,000 × 200 g candles" can mean a thousand candles each holding 200 g of wax, or a thousand candles each weighing 200 g when they are finished. Both are ordinary ways to describe a product, and they give different answers to your question. Under the first reading the fragrance sits on top of the wax and the jar receives 220 g. Under the second the wax and the oil together have to come to 200 g, so the wax comes down to make room.

The second reading is a division rather than a subtraction, because the load is still a percentage of wax. At 10% the fill is 1.1 lots of wax, so the wax is 200 ÷ 1.1 = 181.82 g and the oil is 18.18 g. At 8% the fill is 1.08 lots of wax, so the wax is 200 ÷ 1.08 = 185.19 g and the oil is 14.81 g. Across a thousand candles that is 18.18 kg of oil against 14.81 kg, a saving of 3.37 kg rather than 4.00 kg — 633 g of oil between the two answers to the same question.

The bottom half of that table is the part worth reading twice. Under the wax reading, cutting the load leaves the wax requirement untouched at 200 kg — you simply buy less oil. Under the total-fill reading, cutting the load increases the wax requirement by 3.37 kg, because every gram of fragrance you remove from a fixed 200 g jar has to be replaced by a gram of wax. The saving is still real, since wax is very much cheaper per kilogram than fragrance oil, but a production planner who orders four kilograms less oil and the same wax will come up short on wax somewhere around candle nine hundred.

What four kilograms looks like on a CSI order

Fragrance oil is not sold by the kilogram in a continuous stream; it is sold in packs, and the packs are where a 4 kg reduction becomes a real purchasing change. Spicy Raspberry is stocked at 15 g, 50 g, 100 g, 500 g and 1 kg. A run needing 20.00 kg is 20 kilogram packs; a run needing 16.00 kg is 16. Because the requirement lands on whole kilograms in both cases, the cut removes four complete packs rather than leaving you with an awkward part-bottle — which is not always true, and is worth checking before you assume it.

Now the part a costing blog usually gets wrong. Ordering less does not earn a worse rate here, and ordering more would not have earned a better one. Read the ladder: 15 g is ₹6.60 a gram, 50 g is ₹5.98, 100 g is ₹5.99, 500 g is ₹6.00 and 1 kg is ₹6.00. After the step down from the 15 g bottle the rate is effectively level, and the kilogram pack is fractionally above the 50 g one rather than below it. Buying the full 20 kg as 400 × 50 g bottles would come to ₹1,19,600.00 against ₹1,19,980.00 for 20 kilogram packs — a difference of ₹380.00 across the whole run, and 400 caps to open. Buy the kilogram packs for the handling, not for a rate that is not there.

The wax side of the order deserves the same scepticism, because it is the larger quantity by a very long way. 200 kg of Luxury Soy Wax Chunks can be bought as 40 × 5 kg at ₹2,995.00 each, which is ₹1,19,800.00, or as 20 × 10 kg at ₹5,999.00 each, which is ₹1,19,980.00. The larger pack comes to ₹180.00 more for the identical two hundred kilograms, because it is ₹599.90 a kilogram against ₹599.00. It is a small difference and it runs the opposite way to the instinct. A quantity like this is also well beyond what sits on the shelf at any one time, so treat the whole wax line as a WhatsApp conversation rather than a cart.

Fewer bottles, each one open for longer

A load cut changes how fast you get through a bottle, and that is the effect most production plans miss. At 10% a kilogram of oil scents 50 candles of 200 g of wax. At 8% the same kilogram scents 62.5 — 12.5 more. You are ordering four fewer packs, which is good for cash and for shelf space, and simultaneously making every pack you do order last about a quarter longer, which is the opposite of good if the oil has been sitting since the last festive season.

CSI does not publish a shelf life for its fragrance oils. Some wax pages do — Luxury Soy Wax Chunks is not one of them, while other CSI soy grades state 60 months in cool, dry storage — but the oil pages are silent on it, and this page will not invent a figure. If you are buying ahead for a festive run, ask on WhatsApp before you commit to twenty kilograms of a single scent. In an Indian summer the storage question is not academic: a cupboard on an outside wall in Ahmedabad or Nagpur in May is a materially different environment from the one the same bottle sat in during December, and heat and light are the ordinary enemies of any fragrance material.

Running it on your own candle size and load

The same four steps answer the question at any size. A run of 500 candles at 300 g of wax is 150 kg of wax, 15 kg of oil at 10% and 12 kg at 8%, so 3 kg saved. A run of 2,000 at 100 g is 200 kg of wax and lands on exactly the figures on this page. What never changes is that the saving is two per cent of the wax weight, which is why getting the wax figure right first matters more than anything else in the sum.

What four kilograms does not tell you

This page answers a quantity question and stops there deliberately. It does not tell you that 8% is enough. A load is a formulation decision that happens to have a purchasing consequence, and the order of those two things matters: you find the lowest load at which your candle still performs, in your wax, in your vessel, on your wick, and only then do you work out what that costs. Doing it the other way round produces a run of a thousand candles that are cheaper and quieter than the ones your customers bought last time. One review on the store, from a maker who has been testing fragrances for five years, makes the point from the other side: some oils hold up at the minimum percentage, and the way you find out is to burn them.

Two practical notes on establishing that before a run of this size. Burn the comparison in the vessel you will actually sell, because throw is a function of melt-pool area as much as of load, and a candle that holds at 8% in a wide jar may not in a narrow one. And cure the test candles as long as the real ones: soy throw keeps developing well past the first day, and 14 to 21 days is the ordinary working figure for soy container candles. Judging an 8% candle at 48 hours against a 10% candle you burned last month is not a comparison, it is two anecdotes. There is a live guide on running a controlled burn test and another on testing hot throw before launch.

One last honest word about the size of the prize. Four kilograms is a real quantity, and on Spicy Raspberry it is ₹23,996.00 of fragrance you do not buy. Set against that, the difference between the two wax pack sizes on the same run is ₹180.00, and the difference between the two published parcel bands is ₹400.00. In other words the load decision is worth roughly a hundred times more than the packaging decisions around it — which is exactly why it deserves a burn test rather than a spreadsheet entry.
