My Formula Uses Three Fragrance Oils and the Smallest Component Is Only 10% of the Blend — How Much of That Material Do I Need for a 100 Kg Production Batch?
Aktie
Why are there two answers? Because "100 kg batch" can mean the finished mass or the wax. The oil is 8% of the finished mass, so on 100 kg of wax the blend is 1,00,000 × 0.08 ÷ 0.92. A third reading, 8% of the wax, gives 800 g but a true load of only 7.41%.
What about 6% or 10% load? At 6%: 600 g (finished) or 638.30 g (wax). At 10%: 1,000 g or 1,111.11 g. See the conventions table.
How do I weigh such a small share accurately? Premix the whole blend once, weighing the minor oil at its full 800-odd grams, then dose the premixed blend into each melt. Weighing 8 g of it into every 1 kg melt carries a 6.25% error on a whole-gram scale.
Which 100 kg? Three conventions
CSI's convention throughout this series is that the load is a share of the finished candle: oil = finished weight × load, wax = finished weight − oil. Under that convention a "100 kg batch" is most naturally 100 kg of finished candle. But production batches are often planned from the wax side, because wax is what arrives in bags. Here are the three ways the same words get read, side by side:
| Convention | Load | Wax | Blend | Finished weight | True load | 10% component |
|---|---|---|---|---|---|---|
| A · 100 kg finished | 6% | 94,000 g | 6,000 g | 1,00,000 g | 6.00% | 600 g |
| B · 100 kg wax, true load | 6% | 1,00,000 g | 6,382.98 g | 1,06,382.98 g | 6.00% | 638.30 g |
| C · 100 kg wax + load × wax | 6% | 1,00,000 g | 6,000 g | 1,06,000 g | 5.66% | 600 g |
| A · 100 kg finished | 8% | 92,000 g | 8,000 g | 1,00,000 g | 8.00% | 800 g |
| B · 100 kg wax, true load | 8% | 1,00,000 g | 8,695.65 g | 1,08,695.65 g | 8.00% | 869.57 g |
| C · 100 kg wax + load × wax | 8% | 1,00,000 g | 8,000 g | 1,08,000 g | 7.41% | 800 g |
| A · 100 kg finished | 10% | 90,000 g | 10,000 g | 1,00,000 g | 10.00% | 1,000 g |
| B · 100 kg wax, true load | 10% | 1,00,000 g | 11,111.11 g | 1,11,111.11 g | 10.00% | 1,111.11 g |
| C · 100 kg wax + load × wax | 10% | 1,00,000 g | 10,000 g | 1,10,000 g | 9.09% | 1,000 g |
A and B are both correct formulas for an 8% candle. They answer different questions: A asks "how much oil for 100 kg of candles", B asks "how much oil for 100 kg of wax". C is the common shortcut that under-doses: 8 g of oil per 100 g of wax is a 7.41% candle, not 8%. If your formula was tested under C, keep using C, because that is the candle you approved; just know that its true load is lower than its label. To hit a true load on a fixed wax weight, the formula is oil = wax × L ÷ (1 − L).
Allowances and the full blend
The minor component is bought as part of the blend, so the allowance goes on the whole blend first and is then split. With a 3% pour-loss allowance (a working assumption for a large, well-run batch; measure your own), here are all three oils under conventions A and B:
| Oil | Share | A: need | A: packs | A: price | B: need | B: packs | B: price |
|---|---|---|---|---|---|---|---|
| Jasmine | 60% | 4,944.0 g | 5 × 1 kg | ₹19,615.00 | 5,373.9 g | 5 × 1 kg + 4 × 100 g | ₹21,335.00 |
| Raat Ki Rani | 30% | 2,472.0 g | 2 × 1 kg + 1 × 500 g | ₹16,935.00 | 2,687.0 g | 2 × 1 kg + 1 × 500 g + 2 × 100 g | ₹18,335.00 |
| Gilli Mitti (Patchouli) | 10% | 824.0 g | 1 × 500 g + 3 × 100 g + 1 × 50 g | ₹7,616.00 | 895.7 g | 1 × 500 g + 4 × 100 g | ₹8,064.00 |
| Total | 100% | 8,240.0 g | ₹44,166.00 | 8,956.5 g | ₹47,734.00 |
The difference between the two readings is ₹3,568.00 of oil across the three lines, and 716.5 g of blend. Jasmine is among the 24 oils in the catalogue whose kilo saves 5% or more per gram (8.8% against its 100 g), so the large line is bought in kilos. Raat Ki Rani's kilo is 3.2% cheaper than its 100 g. Gilli Mitti is flat, so it is bought to the nearest 50 g. For more than the listed 1 kg of any oil, CSI quotes on WhatsApp; no volume discount figure is published.
Buying the minor component
For a flat-priced oil like Gilli Mitti, there is no per-gram reason to round up to a kilo. Here are the options for each convention, with the spare grams and cost:
| Need | Packs | Grams | Spare | Price |
|---|---|---|---|---|
| 824 g (A) | 1 × 500 g + 3 × 100 g + 1 × 50 g | 850 g | 26 g | ₹7,616.00 |
| 824 g (A) | 1 × 1 kg | 1,000 g | 176 g | ₹8,960.00 |
| 895.65 g (B) | 1 × 500 g + 4 × 100 g | 900 g | 4.35 g | ₹8,064.00 |
| 895.65 g (B) | 1 × 1 kg | 1,000 g | 104.35 g | ₹8,960.00 |
The kilo is the simpler order, one bottle, but the spare 104–176 g of a ₹8.96-a-gram oil is ₹1,576.96 of stock sitting on the shelf under convention A. If the blend is a steady seller, that spare is simply the start of the next batch. If it is a one-off, buy close to the need. The same logic applies to any minor component: check the oil's price ladder first. Where the kilo is a real saving, as for Jasmine, round up; where the price is flat, buy to the nearest listed size above the need.
| Pack | Price | Per gram | Share of an 824 g need |
|---|---|---|---|
| 15 g | ₹140.00 | ₹9.33 | 1.8% |
| 50 g | ₹448.00 | ₹8.96 | 6.1% |
| 100 g | ₹896.00 | ₹8.96 | 12.1% |
| 500 g | ₹4,480.00 | ₹8.96 | 60.7% |
| 1 kg | ₹8,960.00 | ₹8.96 | 121.4% |
| Pack | Price | Per gram |
|---|---|---|
| 15 g | ₹103.00 | ₹6.87 |
| 50 g | ₹230.00 | ₹4.60 |
| 100 g | ₹430.00 | ₹4.30 |
| 500 g | ₹1,961.00 | ₹3.92 |
| 1 kg | ₹3,923.00 | ₹3.92 |
| Pack | Price | Per gram |
|---|---|---|
| 15 g | ₹130.00 | ₹8.67 |
| 50 g | ₹370.00 | ₹7.40 |
| 100 g | ₹700.00 | ₹7.00 |
| 500 g | ₹3,387.00 | ₹6.77 |
| 1 kg | ₹6,774.00 | ₹6.77 |
Weighing a small share of a big batch
A 100 kg batch is rarely one melt. It is poured in melts sized to your equipment, and the question is where the minor component gets weighed. If you weigh the three oils separately into every melt, the minor oil is a small weighing every time. If you premix the whole blend first, it is weighed once, at full size:
| Method | Minor oil per weighing | Possible error | Error in that component |
|---|---|---|---|
| Weigh into each 1,000 g melt | 8 g | ±0.5 g | ±6.25% |
| Weigh into each 5,000 g melt | 40 g | ±0.5 g | ±1.25% |
| Weigh into each 10,000 g melt | 80 g | ±0.5 g | ±0.62% |
| Premix the whole blend once | 800 g | ±0.5 g | ±0.06% |
Premixing turns the hardest weighing in the batch into the easiest. The premixed blend is then added to each melt as one weight: 80 g of blend per 1 kg melt, 800 g per 10 kg. Those are large, forgiving numbers. For melts, CSI lists a Mini Electric Wax Melter, 1 litre (₹2,360.00) and an Electric Wax Melter in 10 kg (₹21,240.00) and 20 kg (₹25,960.00) capacities; throughput is not published, so time your own melts.
The 100 kg of wax
Under convention B you need exactly 100 kg of wax; under A, 92 kg, plus your allowance either way (103 kg and 94.76 kg at 3%). CSI's container wax bags are listed up to 10 kg: Luxury Soy Wax Chunks at ₹5,999.00 per 10 kg or ₹2,995.00 per 5 kg, rated up to 13%. Natural Soy Pearl Wax is listed in a 50 kg bag at ₹21,240.00 (₹424.80 a kilo), but no fragrance ceiling is quoted for it in this series; check its product page or ask CSI before running 8% in it. For 100 kg, ask for a WhatsApp quote; no volume discount figure is published. Counting candles from 100 kg of wax works the wax side of a batch this size.
For the small-batch end of the same problem, scaling a 30 g test blend covers weighing precision in tests. For a three-oil order sheet at 500 candles, see the 50:30:20 page, and for a two-oil blend at 100 candles, the 70:30 lavender-vanilla page. Once the batch becomes a monthly routine, monthly consumption and reorder levels at 5,000 candles sets reorder points for every component.
The same convention question decides the wax. Calculating wax without treating finished candle weight as wax weight sets it out for 2,000 candles, and 200 g candles from 50 kg of wax works the wax-first direction with a wastage allowance.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. CSI sells the single oils; the blend is your formula. This page recommends buying a flat-priced minor oil to the need rather than to a round kilo, which sells less oil.
