My Old Wax Held 10% Fragrance Without Problems but My Replacement Wax Develops Oil Droplets — Can Practical Fragrance Capacity Differ Between Waxes?
Share
Is 10% allowed in every CSI wax? Only Chunks (up to 13%) and CSI 464 (up to 10%) have stated ceilings in this series. In CSI 464, 10% is the ceiling — no headroom. Soy Pearl and CSI 468: none quoted; ask CSI on WhatsApp.
What should I check first? Your convention. "10% of wax" is only 9.09% of the candle; a new batch sheet written as a true 10% adds 11.1% more oil.
How do I find the new load? 12 candles: old wax 10% as control, new wax at 10%, 9%, 8%; hot and cool spots; burn one of each. Approve the highest step that stays dry and throws.
Yes — and "stated maximum" and "practical capacity" are different numbers
Practical fragrance capacity — how much of a particular oil a wax will hold in your candle, through cure and storage, without oil appearing on the surface or at the glass — is a property of the wax–oil pair and your conditions. It can differ between waxes. It can differ between oils in the same wax. And it can sit well below the wax maker's stated maximum, because a stated maximum is a formulation limit the maker is willing to stand behind, not a promise that every oil will be held at that level in every jar and climate.
So the short answer is yes, practical capacity can differ between waxes, and droplets in the new wax at an unchanged 10% are the most direct evidence you will get that it does for this oil. The useful answer is what to do with that evidence: check which ceilings are actually published, check that your "10%" really is 10% in the convention you think, and then run a load ladder in the new wax beside a control in the old one to find the highest load the new wax holds dry — and whether that load still throws.
The ceilings matter here, so here they are exactly. Of CSI's four container waxes, only two have a stated fragrance ceiling in this series: Luxury Soy Wax Chunks up to 13% and Luxury Soy Wax CSI 464 up to 10%. So 10% is inside the stated ceiling only in Chunks, and in CSI 464 it is the stated ceiling — no headroom at all. Natural Soy Pearl Wax and Premium Coconut Soy Wax CSI 468 have no ceiling quoted in this series, so 10% in either is a test value, not a figure anyone has published. The worked example moves a Woody Oud candle from Chunks at 10% to Natural Soy Pearl. We are not saying Soy Pearl holds less than Chunks — CSI publishes no oil-retention data for any wax. Your droplets are the data.
What is published, and what is not
Before testing, get the facts straight. The table below is every fragrance ceiling on record for CSI's container waxes in this series, and what 10% means against each.
| Wax | Stated ceiling | 10% against it | What that means for you |
|---|---|---|---|
| Luxury Soy Wax Chunks | Up to 13% | Inside, 3 points below | Allowed; practical capacity still to be proven for each oil |
| Luxury Soy Wax CSI 464 | Up to 10% | Exactly at the ceiling | Allowed but no headroom; any measuring error takes you over |
| Natural Soy Pearl Wax | Not quoted in this series | Unknown | Check the product page or ask CSI on WhatsApp; 10% is a test value |
| Premium Coconut Soy Wax CSI 468 | Not quoted in this series | Unknown | Check the product page or ask CSI on WhatsApp; 10% is a test value |
| Any blend you make | None published | Unknown | Your own formula — test it; 4813, 4816 |
Two consequences follow. First, if your replacement wax is CSI 464, a 10% formula is legal on paper but has no margin: a scale that reads a gram high, or oil added as a percentage of wax instead of the finished candle, puts you over. For CSI 464 a working load below 10% is the prudent choice for any formula you want to repeat reliably. Second, if your replacement is Soy Pearl or CSI 468, nobody has told you 10% is allowed at all. Ask for the wax maker's stated maximum before you settle a production load; CSI can check it on WhatsApp.
First check: is your 10% really 10%?
CSI's convention is that load is a share of the finished candle: oil = candle weight × load. Many makers write recipes as a share of the wax instead: 100 g of oil into 1 kg of wax, "10%". That is actually 9.09% of the finished 1,100 g. If your old recipe card was written one way and your new batch sheet the other, the new candles contain more oil than the old ones — even though both say 10%.
| How the recipe is written | Oil into 1 kg of wax | True load (share of finished candle) | Oil in a 200 g candle |
|---|---|---|---|
| "10% of wax" (oil = wax × 10%) | 100 g | 9.09% | 18.18 g |
| "10% of candle" (CSI convention) | 111.11 g | 10.00% | 20.00 g |
| Difference | 11.11 g | 0.91 points | 1.82 g more oil (11.1%) |
That 11.1% difference in oil is not large, but at the edge of what a wax holds it can be the difference between dry and droplets. Check both recipe cards. If the old wax was really running at 9.09% and the new batch at a true 10%, you have changed two things — the wax and the load — and the ladder below must include the old true load. The wax-change hub puts load under CONFIRM for exactly this reason.
Why two waxes can hold the same oil differently
In general candle-making practice, fragrance oil sits within the wax as it cools and crystallises. How much of a particular oil a wax can keep bound — and how well it keeps it through warm days, cool nights and the vibration of a delivery van — depends on the wax's make-up and on the oil's own make-up. Some oils commonly behave as "heavy" in one wax and unremarkable in another. That is why capacity is best thought of per pair. CSI publishes no oil composition for its oils and no oil-retention data for its waxes, so nothing on this page predicts where Woody Oud will sit in Soy Pearl. The ladder does.
Where the droplets appear is a clue, not a diagnosis. Beads on the top surface after cure commonly point to more oil than the set wax is holding. Oil at the glass edge or a wet ring can also come from shrinkage and adhesion changes, which a wax change can alter too — the rough-tops post covers the surface side. Droplets that appear only after a hot spell are a storage-stability result — the summer-sweating post covers that test. This page is about the load itself.
| Where you see oil | Commonly associated with | Test that separates it |
|---|---|---|
| Beads on the top after cure, cool room | Load above what the set wax holds | Load ladder (this page) |
| Only after hot days | Storage stability of the pair | Summer storage test |
| At the glass edge, wet ring | Shrinkage / adhesion change | Process trials |
| Pooled under the lid in transit | Load and heat together | Ladder + hot-spot storage |
| In the pool when lit, separated | Oil not fully mixed in / added at the wrong temperature | Re-pour following the new wax maker's instructions |
The load ladder
Three loads in the new wax, one control in the old — each poured, cured and stored identically. The counts, loads and checkpoints are labelled working practice. The ladder stops at 10% because that is the load you were running; it never goes above 13% in any wax, and for CSI 464 it would not go above 10%.
| Variant | Load | Oil | Wax | Candles |
|---|---|---|---|---|
| Control · Chunks | 10% | 20 g | 180 g | 3 |
| Soy Pearl | 10% | 20 g | 180 g | 3 |
| Soy Pearl | 9% | 18 g | 182 g | 3 |
| Soy Pearl | 8% | 16 g | 184 g | 3 |
| Variant | Top: dry / beads / wet | Glass edge | Tissue | Hot throw (blind 0–5) | Pool / flame / jar vs control |
|---|---|---|---|---|---|
| Control · Chunks 10% | ___ | ___ | clean / marked | ___ | reference |
| Soy Pearl 10% | ___ | ___ | clean / marked | ___ | ___ |
| Soy Pearl 9% | ___ | ___ | clean / marked | ___ | ___ |
| Soy Pearl 8% | ___ | ___ | clean / marked | ___ | ___ |
The priced ladder kit
Grams use the CSI convention plus a 5% pour-loss allowance, labelled as a working assumption. The three Soy Pearl steps need 1,719.9 g of wax; the control needs 567.0 g of Chunks; Woody Oud for all twelve candles is 233.1 g.
| Item | Need | Buy | Price |
|---|---|---|---|
| Natural Soy Pearl Wax | 1,719.9 g | 2 × 1 kg | ₹900.00 |
| Woody Oud Fragrance Oil | 233.1 g | 2 × 100 g + 1 × 50 g | ₹1,177.64 |
| Eco Candle Wicks Thin C1 | 12 + 2 spare | 1 × 20 | ₹118.00 |
| White Matte Glass Jar | 12 | 3 packs of 5 | ₹1,062.00 |
| Kit, control wax from stock | ₹3,257.64 | ||
| Luxury Soy Wax Chunks (only if you hold none) | 567.0 g | 2 × 500 g | ₹598.00 |
| Kit, control wax bought | ₹3,855.64 |
Woody Oud is priced flat from 100 g (₹4.53 a gram at 100 g, 500 g and 1 kg), so 233.1 g is cheapest as two 100 g bottles and a 50 g (₹1,177.64); the 500 g bottle (₹2,265.60) would buy nothing cheaper per gram. Two 1 kg bags of Soy Pearl (₹900.00) leave 280.1 g for a narrower second ladder if the edge falls between two steps.
| Pack | Price | Per kg | Candles at 180 g wax (10%) |
|---|---|---|---|
| 1 kg | ₹450.00 | ₹450.00 | 5.56 |
| 5 kg | ₹2,124.00 | ₹424.80 | 27.78 |
| 10 kg | ₹4,248.00 | ₹424.80 | 55.56 |
| Pack | Price | Per kg | Candles at 180 g wax (10%) |
|---|---|---|---|
| 500 g | ₹299.00 | ₹598.00 | 2.78 |
| 1 kg | ₹599.00 | ₹599.00 | 5.56 |
| 5 kg | ₹2,995.00 | ₹599.00 | 27.78 |
| 10 kg | ₹5,999.00 | ₹599.90 | 55.56 |
| Pack | Price | Per gram | Test candles at 20.0 g |
|---|---|---|---|
| 15 g | ₹93.22 | ₹6.21 | 0.75 |
| 50 g | ₹271.40 | ₹5.43 | 2.50 |
| 100 g | ₹453.12 | ₹4.53 | 5.00 |
| 500 g | ₹2,265.60 | ₹4.53 | 25.00 |
| 1 kg | ₹4,531.20 | ₹4.53 | 50.00 |
What a lower approved load does to cost
If the ladder settles on 9% or 8% in Soy Pearl, the cost per candle falls, because Woody Oud costs far more per gram than wax. At the 1 kg oil rate (₹4.53 a gram) and the 5 kg Soy Pearl rate (₹424.80 a kilo):
| Load | Oil | Oil cost | Wax cost | Oil + wax |
|---|---|---|---|---|
| 10% | 20 g | ₹90.62 | ₹76.46 | ₹167.09 |
| 9% | 18 g | ₹81.56 | ₹77.31 | ₹158.88 |
| 8% | 16 g | ₹72.50 | ₹78.16 | ₹150.66 |
| 7% | 14 g | ₹63.44 | ₹79.01 | ₹142.45 |
Moving from 10% to 9% saves ₹8.21 a candle, or ₹3,285.12 on a 400-candle run — a real number, and a trap if it tempts you to accept a lower load that no longer throws. The ladder's burn candles are there to stop that. Comparing total finished-candle economics weighs load, wax price and throw together, and the lower-effective-load post covers redesigning a formula around a lower load properly.
Deciding, and recording the new load
| Result | Verdict | Next step |
|---|---|---|
| Soy Pearl 10% dry like control; droplets earlier were a convention error | Capacity was never the problem | Fix the batch sheet; KEEP 10% after burn checks |
| 10% beads; 9% dry at all checkpoints; throw acceptable | Practical capacity for this pair sits between 9% and 10% | Approve 9% for Woody Oud in Soy Pearl |
| 10% and 9% bead; 8% dry; throw acceptable | Wider gap | Approve 8%; consider a narrower ladder for other heavy oils |
| All steps bead, control dry | Pairing problem | Keep this oil in the old wax |
| Control beads too | Your 10% was always at the edge | Re-ladder both waxes |

If the droplets appear only in summer, the summer-sweating post runs the storage side. If you run several heavy oils, the ten-fragrance post and the twenty-fragrance post show how to ladder a representative few. If the replacement is CSI 464 and your formula is 10%, remember you are at its stated ceiling; the wax-change checklist puts that on the CONFIRM line. And if you are changing from pure soy to a blend to carry more fragrance, the soy-paraffin post covers what that reopens.

Non-price figures and assumptions: CSI convention: load is a share of finished weight (200 g at 10% = 20 g oil + 180 g wax). Oil added at 10% of wax weight gives a true load of 9.09%; to hit a true L on a fixed wax weight, oil = wax × L ÷ (1 − L). Only two fragrance ceilings are published for CSI waxes in this series (Chunks 13%, CSI 464 10%); they are wax makers' formulation maximums, not regulatory or optimum. The ladder, three candles per variant, storage spots, checkpoints and 5% pour loss are labelled working practices. CSI publishes no oil-retention, crystallisation or oil-composition data. Costs exclude labour, packaging, freight and GST. Diwali 2026 falls on 8 November.
