I Want to Build a Strong-Fragrance Candle Collection — How Do I Select Fragrance Oils Based on Performance in Wax Rather Than How Powerful They Smell From the Bottle?
Share
How many oils should I screen? As a suggested starting point, eight in 15 g bottles for a five-oil collection, so weaker ones can drop out.
What should I score? Room throw while burning, cold throw, burn behaviour, colour change, cost per candle and supply. Weight them to suit your brand.
Do strength ratings on pages help? They are each page's own wording, not measured data. Use them to shortlist, never to approve.
Why the bottle is the wrong judge
Neat fragrance oil at room temperature presents its lightest materials first, at full concentration. A candle presents the same oil diluted to a few percent, locked in wax, and released only from a warm pool. Some oils keep their impact through that change; others lose much of it. You cannot tell which from the bottle.
Product-page ratings are also only a starting hint. CSI pages rate Lavender Strong, Eucalyptus Spearmint and Vanilla Bean moderate to strong, and Lemongrass and Lime moderate. Those are the pages' own descriptions, not measured data, and they tell you nothing about your jar, your wax or your wick. For a collection marketed on strength, the only rating that counts is the one you record in a burning candle.
The selection funnel, stage by stage
A funnel spends little on many oils and more on a few. Each stage removes the weakest before the next costs more.
Every count and load in that list is a suggested starting point. A small collection might screen six oils; a brand built entirely on strength might screen twelve.
The funnel also protects you from a common trap: falling for one oil early and then testing everything else against it unfairly. Because every oil in the screen gets the same jar, wax, load and wick, the comparison is level. Only at the ladder stage does each oil get its own treatment, and by then you are refining winners rather than rescuing favourites.
A worked first screen: eight CSI oils
Suppose the collection brief is strong, distinct scents across woods, gourmands, fresh and aquatic. Eight CSI oils from the 15 g size make a reasonable first screen. Each is poured at 8% of a 150 g candle in the CSI apothecary jar: 150 × 0.08 = 12 g of oil and 138 g of CSI 464, so each 15 g bottle covers one candle with a little left for a strip.
| Oil | Family | 15 g price | Oil cost per candle at 12 g (from 1 kg) |
|---|---|---|---|
| Woody Oud | Woody oud | ₹93.22 | ₹54.37 |
| Sandalwood | Creamy wood | ₹93.22 | ₹60.32 |
| Roasted Coffee | Gourmand | ₹93.22 | ₹44.86 |
| Dark Vanilla | Gourmand | ₹130.00 | ₹91.75 |
| Lavender | Herbal | ₹105.02 | ₹62.65 |
| Blue Ocean | Aquatic | ₹93.22 | ₹59.47 |
| Eucalyptus Spearmint | Fresh | ₹68.44 | ₹36.82 |
| Bergamot Amber | Citrus amber | ₹105.02 | ₹65.24 |
The eight bottles cost 4 × ₹93.22 + ₹130.00 + 2 × ₹105.02 + ₹68.44 = ₹781.36. Wax for eight candles is 8 × 138 g = 1,104 g, so CSI 464 1 kg ₹507.40 plus 500 g ₹260.00. Add a pack of ten 150 g jars ₹944.00 and Eco C1 20 wicks ₹118.00. The screen comes to ₹2,610.76, before any packaging, labels or labour.
The scorecard: weight what your brand sells
After at least the 48–72 h cure the soy pages state, and again around day 7 as a suggested starting point, burn each screen candle in the same room for the same time. Score each criterion 1–5 and multiply by a weight you choose.
| Criterion | Weight | How to score it |
|---|---|---|
| Room throw while burning | 30 | Return to the room after a brief absence; how strong and how far? |
| Burn behaviour | 20 | Pool width, flame steadiness, mushrooming, soot |
| Cold throw | 15 | Lid off at 72 h; is it noticeable at arm's length? |
| Character in wax | 15 | Does it still smell like the brief, or has it flattened? |
| Colour change | 10 | Compare against an unscented control after a week |
| Cost and supply | 10 | Cost per candle, and are mid-sized packs in stock? |
A strength-led brand weights room throw heavily, but not so heavily that a sooty candle can win. A minimalist white brand might move colour change up to 20 and room throw down. Write the weights down before you burn anything, so you do not adjust them to favour the oil you already like.
| Criterion | Weight | Oil A score | Oil A points | Oil B score | Oil B points |
|---|---|---|---|---|---|
| Room throw | 30 | 4 | 120 | 5 | 150 |
| Burn behaviour | 20 | 3 | 60 | 2 | 40 |
| Cold throw | 15 | 5 | 75 | 4 | 60 |
| Character in wax | 15 | 4 | 60 | 3 | 45 |
| Colour change | 10 | 5 | 50 | 2 | 20 |
| Cost and supply | 10 | 3 | 30 | 4 | 40 |
| Total (of 500) | 395 | 355 |
Oil B throws harder, and it would probably have won the bottle test too. It loses because it burns poorly and discolours, and those are the things a customer sees after the third evening.
Supply is part of performance
An oil that wins the screen but cannot be reordered in sensible sizes is a weak collection member. On the October 2026 pull, Sandalwood's 50 g and 100 g packs, Vetiver's 1 kg and Royal Oud's 100 g were out of stock, as was Chocolate Fudge's 100 g. None of that disqualifies those oils, but it changes how you buy them: a 500 g Sandalwood at ₹2,513.40 is a larger commitment than a 100 g restock would have been.
Before you approve a collection, list each oil's pack sizes and decide which one you will reorder. Ask CSI on WhatsApp (+91 7397976926) for IFRA and MSDS documents for every approved oil, since the pages state these are available on request. Record the date you received them with your formula sheet.
Buy this to test, buy this once validated
To screen: the eight 15 g bottles ₹781.36, CSI 464 1.5 kg ₹767.40, ten 150 g jars ₹944.00 and Eco C1 20 wicks ₹118.00, a total of ₹2,610.76. For the ladder round, buy 50 g of each surviving oil; three loads of a 150 g candle at 6%, 8% and 10% need 9 + 12 + 15 = 36 g, so a 50 g bottle covers each oil with room for a strip. Add Eco C2 10 wicks ₹94.40 for the wick round.
Once validated: buy each approved oil at the pack size its own load and your batch size require, and CSI 464 in 10 kg packs at ₹5,074.00, the same price per kilogram as the smaller packs. The kilograms come last, and only for oils that have won in wax twice. Keep the losing candles' score sheets as well. When you extend the collection next season, the oils that narrowly missed out are your first shortlist, and you will not pay to screen them again.

CANDLEMAKINGSUPPLIESINDIA supplies raw materials and production equipment, not finished candles. This guide separates general candle-making practice from what CSI's own product pages state, says plainly where CSI publishes no figure (wick sizes, burn times, hardness), and labels every wick, load, test count or margin as a starting point for your own validation.
Prices are live CSI prices from October 2026; product pages are authoritative. Where a spec is not published — such as a wick size for your jar, a mould's cycle life or a wax's survival temperature — this guide says so rather than filling the gap.

Assumptions: Fragrance load is a percentage of total candle weight (200 g = 184 g wax + 16 g oil at 8%); CSI wax pages phrase their ceilings as a share of wax weight. Material cost per candle covers wax, oil, vessel, wick and dye only — it excludes packaging, labels, labour, shipping and GST. CSI publishes no wick sizing chart, burn times or wax survival temperatures, so every wick named is a candidate to test. Retail prices, budgets, margins and packaging costs are the reader's own figures. Test counts and loads are suggested starting points.
