I Need 10 Kg of a Custom Fragrance Blend for Production — Should I Premix the Entire Fragrance Concentrate Before Adding It to Wax or Blend Each Component Directly into the Wax?
शेयर करना
Is there any reason to add each oil directly? For a small, one-off run, or while you are still adjusting the ratio, direct addition keeps you flexible and needs no storage container. Once the ratio is fixed and the run is large, premixing is the better control. See pros and cons.
How should I make a 10 kg premix? In 2 sub-lots of 5 kg, each weighed by cumulative addition, mixed, rested and checked against the retained sample before use. Stir before each draw and dose 800 g into each 10 kg finished batch at 8%. See the method.
What does 10 kg of blend make? At 8% of finished weight, 125 kg of candles: 625 candles of 200 g, with 115 kg of wax. The example blend's components cost ₹45,095.40 in 1 kg packs.
Premix vs direct, side by side
When you add components directly, the blend is created fresh inside every batch of wax. Its ratio depends on three weighings done that day, by whoever is on the melter, in whatever order they remember. When you premix, the blend is created once, checked once, and then treated like a single fragrance oil. Every batch receives the same thing. That is the core of the argument, and most of the table below follows from it.
| Question | Premix first | Direct into wax |
|---|---|---|
| Is the ratio identical in every batch? | Yes — one homogeneous lot | Only as good as each day's three weighings |
| Weighings for 10 kg over 13 batches | 19 | 39 |
| Chance to skip or double a component | Once per sub-lot, checked | Every batch |
| Quality check against approved sample | Once per sub-lot, before any wax | Only after pouring, per batch |
| Separation or haze between components | Seen in the premix, before wax | Hidden in the wax |
| Cost of a weighing mistake | A whole sub-lot, unless caught at the check | One wax batch |
| Flexibility to adjust the ratio mid-run | Low — ratio is fixed in the lot | High |
| Needs a clean, closable container and storage | Yes | No |
| Cash committed up front | All components for the sub-lot | Can buy as you go |
The two genuine weaknesses of premixing are the single point of failure and the loss of flexibility. A mistake in a 10 kg premix is a mistake in 625 candles. The fix is not to avoid premixing but to make it in sub-lots and to check each one before it touches wax. Flexibility matters only while the formula is still moving; once it has passed its confirmation stage, you want it not to move. Staging signature development covers when a formula is ready to fix.
The numbers for 10 kg
At 8% of finished weight (CSI's convention: oil = W × L), 10 kg of blend scents 125 kg of finished candles: 115 kg of wax plus 10 kg of oil, or 625 candles of 200 g. How that splits into wax batches depends on your melter. As a worked example, take batches of 10 kg finished weight each, 9.2 kg of wax plus 800 g of oil. That is 12 full batches and one half batch of 5 kg, 13 batches in all. Check your own melter's working capacity; CSI lists an Electric Wax Melter with 10 kg (₹21,240.00) and 20 kg (₹25,960.00) capacities, and a 1 litre Mini Electric Wax Melter (₹2,360.00) for small batches.
| Batch | Wax | Premix dose | Or direct: Jasmine | Direct: Sandalwood | Direct: Lemongrass and Lime |
|---|---|---|---|---|---|
| 1–12 (each) | 9,200 g | 800 g | 400 g | 240 g | 160 g |
| 13 (half batch) | 4,600 g | 400 g | 200 g | 120 g | 80 g |
| Total | 115,000 g | 10,000 g | 5,000 g | 3,000 g | 2,000 g |
Precision is not the issue here: at these weights, a whole-gram scale's ±0.5 g is ±0.31% of the 160 g Lemongrass and Lime dose in a direct batch, and ±0.05% of the 1,000 g in a 5 kg sub-lot. I'm Scaling a Custom Fragrance Blend from 100 g to 5 Kg — How Do I Preserve the Exact Ratios and Minimise Weighing Errors? works through that maths. The real risk in direct addition is human: 39 opportunities to pick up the wrong bottle, skip a component when interrupted, add one twice, or use last week's notes. A premix reduces those opportunities to 19, and makes the most error-prone ones happen at a bench with a checklist, not beside a hot melter.
How to premix 10 kg
Storing and drawing from a premix
A premix is a fragrance oil in its own right, and it should be stored like one: in a clean, dry, tightly closed container suited to fragrance oil, filled close to the top to limit air space, somewhere cool and away from direct sunlight and heat. The MSDS for each component oil, available from CSI on WhatsApp, carries the storage and handling guidance. CSI does not list a storage container for blends in our data, so use a suitable container you already have, and ask if you are unsure.
Draw from it by weight, not by volume. Stand the container on the scale, tare, and pour out 800 g into a clean jug, or tare the jug and pour into it. Before every draw, stir or gently invert the container, even if it looks uniform; it costs a minute and protects against any settling between batches. Add the dose to the wax as the wax maker instructs (for CSI 464, CSI's own guidance is 80–90°C; confirm on the product page) and stir the wax batch thoroughly. How long to mix fragrance into a large batch and distributing fragrance uniformly through 10 kg cover that step.
| Wax batch | Premix sub-lot | Stirred before draw? | Target dose | Actual dose | Initials |
|---|---|---|---|---|---|
| 1 | 1 | 800 g | |||
| 2 | 1 | 800 g | |||
| 3 | 1 | 800 g | |||
| 4 | 1 | 800 g | |||
| 5 | 1 | 800 g | |||
| 6 | 1 | 800 g | |||
| 7 | 1 (200 g) + 2 (600 g) | 800 g | |||
| 8 | 2 | 800 g | |||
| 9 | 2 | 800 g | |||
| 10 | 2 | 800 g | |||
| 11 | 2 | 800 g | |||
| 12 | 2 | 800 g | |||
| 13 | 2 | 400 g |
Each 5 kg sub-lot covers six full batches (4,800 g) with 200 g left over, which goes into batch 7 alongside the start of sub-lot 2. Log both sub-lots against that batch. The retained samples (30–50 g per sub-lot) also come out of the 10 kg, so either buy an extra 100 g of each component for them, or accept a slightly smaller final half batch.
If you add components directly
Direct addition is still the right choice for small runs, first production batches of a formula that may change, or when you have no suitable container. Done carefully, it works. The controls are the same ones a premix builds in, applied every batch:
| Control | Why |
|---|---|
| Pre-weigh all three components into labelled cups before the wax is ready | Weighing away from the hot melter, without time pressure |
| Add them in the same order every batch, ticking each on the sheet | Makes a skipped or doubled component visible |
| Keep the empty cups until the batch is poured | A quick visual check that all three went in |
| Scrape or rinse cups consistently (or weigh the empty cups) | Oil clinging to cups is lost from the batch |
| Log component lots per batch | Traceability when something differs |
Notice that the first control is, in effect, a tiny premix made in three cups. That is why most makers who start with direct addition move to a premix as soon as their runs grow: it is the same discipline, done once instead of every batch. A repeatable fragrance mixing protocol sets the whole process out for commercial batches.

Shopping list: 10 kg of blend, and the wax it goes into
The components come to ₹45,095.40 in 1 kg packs, ₹4.51 per gram of blend, or ₹72.15 of oil in each 200 g candle at 8%. Buying the same quantities in 500 g packs would cost ₹45,090.40: Jasmine's 500 g is ₹1,961.00, fractionally below half its 1 kg price, so ten 500 g packs save ₹5.00 at the cost of twice the bottles; for Sandalwood and Lemongrass and Lime the two routes cost the same. On the listed catalogue, bigger packs mostly buy convenience, not a lower rate.

Oil and wax together come to ₹1,14,079.40 for 625 candles, ₹182.53 each before wick, jar, labour, packaging, freight and GST. CSI's listed wax packs stop at 10 kg; for the full 115 kg in one order, ask on WhatsApp for a quote. The container for the premix is not in CSI's listed catalogue in our data; use a clean, closable fragrance-suitable container you already own.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles, and it does not sell a blending service. CSI sells single fragrance oils; any blend you build from them is your formula. The page recommends premixing for production runs, and says plainly that small makers with irregular orders may be better off buying and adding components as they go, keeping cash in hand.
Every oil and wax price on this page is CSI live pricing, pulled on 24 September 2026. Wick, jar, scale and thermometer prices are those verified for Blog 760 on 10 September 2026; the jug, stirring sticks and other equipment were pulled on 24–25 September 2026. Out-of-stock sizes are flagged, never offered as buyable. Grams, ratios, per-gram and per-candle figures are plain arithmetic on those prices, shown to two decimals so you can check them. The 10 kg finished batch size and the resulting 13 batches are a worked example; melter working capacity varies. Weighing counts are arithmetic on that example.
CSI publishes no throw, cure-time, composition or discolouration data for any individual oil, so nothing here ranks oils by performance.

Non-price figures and assumptions: Load is a share of the finished weight (oil = W × L): 10 kg of blend at 8% scents 125,000 g of candles (625 × 200 g) with 115,000 g of wax; with a fixed 10 kg of wax, 8% of the finished candle needs 869.57 g of blend (oil = wax × L ÷ (1 − L)). The 10 kg finished batch (9.2 kg wax + 800 g oil), the resulting 13 batches, the 2 × 5 kg sub-lots, the 24-hour rest, the 3–5 minute mix and the 30–50 g retained sample are working examples, not specifications. Weighing counts: direct = 13 × 3 = 39; premix = 2 × 3 + 13 = 19. Rounding error assumes a whole-gram scale (±0.5 g). CSI's CSI 464 guidance is 80–90°C; confirm on the product page.
