CSI Jar & Container Guides · Fragrance Load
A higher fragrance load does not need a bigger jar or more wax. The jar holds the same total to your fill line; 6% to 10% simply moves 6 g of a 150 g candle from wax to oil. The part that changes is the bill.
135 g
wax in a 150 g candle at 10% load, down from 141 g at 6% · CSI live pricing, September 2026
Quick answers — read this first
Does 10% load need more wax per jar than 6%? No, less. The jar holds the same total weight to your fill line; a higher load moves grams from wax to oil. A 150 g candle is 141 g wax + 9 g oil at 6%, and 135 g wax + 15 g oil at 10%.

Does the total fill weight change? No, as long as the load is a percentage of the total candle weight and you pour to the same line. Oil and wax differ a little in weight per millilitre, so confirm with one weighed test pour at 10%.

What does it cost? Per 150 g candle: 6 g less wax (₹3.04 of CSI 464) and 6 g more oil. With Lavender at the 1 kg price, the net change is ₹28.29 more per candle; with Citrus Lemon, ₹13.95.

What else should I check? That 10% is inside both ceilings (CSI 464's page says up to 10%), and whether your wick still copes. The load change alters grams and cost, not the jar.
The short answer
The rule: wax = total candle weight × (1 − load). Oil = total × load. The total is fixed by the jar and your fill line.
At 150 g: 6% = 9 g oil + 141 g wax; 8% = 12 g + 138 g; 10% = 15 g + 135 g. Oil up 67%, wax down 4.3%.
The mistake: keeping 150 g of wax and adding 15 g of oil on top. That is a 165 g candle, about 0.6 cm higher in our standard jar, and a load of 9.1%, not 10%.
The money: 100 candles at 10% instead of 6% take 600 g less wax and 600 g more oil. With Lavender, the order goes from ₹12,832.00 to ₹15,452.00.

Straight answer
I changed my fragrance load from 6% to 10%. Will that change how much wax I need to put into each jar?
Yes: you need a little less wax, not more, and the same total fill weight. The jar's fill weight is set by its volume to your fill line, and a load change does not move that line. CSI's convention, and the one this guide uses, is load as a percentage of the finished candle's total weight. So in a 150 g candle, 6% is 9 g of oil and 141 g of wax; 10% is 15 g of oil and 135 g of wax. You weigh out 6 g less wax per jar and 6 g more oil. The jar is filled to the same line, give or take a gram or two because oil and wax weigh slightly differently per millilitre; one weighed test pour at 10% confirms it. The change that matters is cost: 6 g of oil costs far more than 6 g of wax, so with Lavender and CSI 464 each candle's materials rise from ₹118.53 to ₹146.81. Before you pour a batch, check that 10% is within both the wax's and the oil's stated maximum, and burn-test the wick at the new load.
One line: same jar, same total, less wax, more oil: at 150 g, 141 + 9 becomes 135 + 15, and the bill rises by the oil, not the wax.
Test 6%, 8% and 10% side by side before you change a batch. Nine 150 g candles (three per load) take 1,242 g of CSI 464 and 108 g of oil: 2 kg of wax (₹1,014.80) and 100 g + 15 g of Lavender (₹645.02) cover it, in jars you already own. In stock on 26 September 2026.

Why the jar does not care about your load

The jar decides how much candle fits. The load only decides what that candle is made of.

A fill weight is a jar fact: the volume below your fill line multiplied by the weight per millilitre of what you pour. Nothing in a load change touches the jar, and nothing touches the fill line. What changes is the recipe inside a fixed total. That is why the question in the title has a slightly surprising answer: more fragrance means less wax per jar, never more.

It only works this way if you express the load as a share of the finished candle's total weight, which is CSI's convention across this series. Write it down once and every recipe after it is two multiplications:

The two formulas · load on total candle weight
Start from the jar's fill weight, not from a bag of wax
You need Formula 150 g at 6% 150 g at 10%
Fragrance oil fill weight × load 150 × 0.06 = 9 g 150 × 0.10 = 15 g
Wax fill weight × (1 − load) 150 × 0.94 = 141 g 150 × 0.90 = 135 g
Check oil + wax = fill weight 9 + 141 = 150 g 15 + 135 = 150 g

The fill weight itself, 150 g here, is the series' planning figure for CSI's 200 ml matte jar. It came from a water-fill and the 0.86–0.9 rule of thumb, and it should come from your own weighed test pour; how is in the fill-weight hub. Once you have it, the load never changes it.

The one small caveat: oil and wax are not the same weight per millilitre

If you pour by weight (tare the jar, pour to 150 g), the total is exactly the same at every load; the surface height may shift by a hair. If you pour to a tape line, the finished weight at 10% may differ from 6% by a gram or two, because fragrance oil's weight per millilitre differs a little from wax's. Neither CSI's wax nor oil pages state a density, so do not calculate it: pour one jar at 10% to your line and weigh it. If it lands within a couple of grams of your recorded fill weight, nothing changes.

Mistake: keeping the old 150 g of wax and adding 10% "on top": 150 g of wax plus 15 g of oil. What happens: you now have 165 g of candle in a jar sized for 150 g. In our standard 200 ml jar (about 25 g of candle per centimetre), the surface rises by about 0.6 cm into your headspace, and the true load is 15 ÷ 165 = 9.1%, not 10%. Fix: start from the fill weight and split it; never start from the wax.

The grams at 6%, 8% and 10%, for four candle sizes

Pin this table above the melter. It is the only arithmetic a load change needs.

Four finished weights. Two come from CSI jar listings, quoted as the pages state them ("Capacity: 120 gm" on the Black and Red Shiny jars; "Fill Weight: 180 grams" on the Ceramic Jar); treat them as worked figures, because a listing's number is not your weighed fill. The last column is the one people miss: every 4-point load increase moves 4% of the candle from wax to oil.

The total never changes; the split does

Write your fill weight, not your wax weight, at the top of the recipeThe number the jar holds to your line, from a weighed test pour: for example 150 g. Everything else hangs off it.
2
Check the new load against both ceilingsThe oil page's stated candle load and the wax page's maximum; the lower governs. Lavender states "6-10% for candles" and CSI 464 "Up to 10%", so 10% is allowed and is the maximum.
3
Oil = fill weight × load150 × 0.10 = 15 g. For a batch, multiply by candle count before you open the bottle: ten candles need 150 g of oil.
4
Wax = fill weight − oil150 − 15 = 135 g per candle; ten candles need 1,350 g, plus your usual allowance for pitcher residue and top-ups (how much at 100 candles is in I'm Making 100 Candles in 200 ml Jars — How Do I Calculate the Total Wax and Fragrance Oil I Need Without Making Too Much?).
5
Pour one jar to your line and weigh itIf it lands within a couple of grams of the old fill weight, keep it. If the set surface now sits noticeably higher or lower, check your headspace against the lid before a full batch.
6
Update the spec sheet, including the wick lineRecord load, grams of each, date and the wick that passed at the new load. A wick proven at 6% has not yet been proven at 10%.

"10%" of what? Total weight versus wax weight

Two makers can both say "10%" and put different amounts of oil in the same jar.

Some recipes, and some pages outside CSI, express load as a percentage of the wax weight rather than the finished candle. Both conventions are in use; the problem is mixing them. CSI's guides use total candle weight. Here is what each means for the same 150 g candle:

Same jar, same 150 g candle, two meanings of "10%"
Know which one your recipe, your oil page and your wax page use
Convention Oil Wax Oil as a share of the finished candle
10% of total candle weight (CSI convention) 15 g 135 g 10%
10% of wax weight, fitted to the same 150 g jar 13.6 g 136.4 g 9.1%
10% "on top" of a full 150 g of wax 15 g 150 g 9.1%, and 15 g too much candle for the jar

The difference between the first two rows is 1.4 g of oil per candle, small in one jar and 140 g of oil across a hundred. Whichever you use, use it every time, and when an oil or wax page quotes a maximum, compare like with like. A page's maximum is a ceiling for that page's own basis; we apply the CSI pages' figures as stated and treat the lower of the two as the limit.

What the change costs per candle, oil by oil

The wax you save is worth a few rupees. The oil you add is worth a few dozen.

Worked example for one 150 g candle, CSI 464 at its 10 kg price (₹0.51 per gram) and each oil at its 1 kg price, excluding the jar, wick, labour, freight, packaging and GST. Five oils whose pages state a candle load and whose every size was in stock on 26 September 2026, ordered by per-gram price, low to high. This ranks cost, not scent.

Oil cost at 6%, 8% and 10% · per 150 g candle · CSI live pricing, 26 September 2026
The net change is 6 g of oil minus 6 g of wax
Oil Per gram (1 kg) Oil at 6% (9 g) at 8% (12 g) at 10% (15 g) 6% → 10% Net change per candle
Citrus Lemon ₹2.83 ₹25.49 ₹33.98 ₹42.48 ₹16.99 more oil, ₹3.04 less wax ₹13.95 (14.4%)
Roasted Coffee ₹3.74 ₹33.64 ₹44.86 ₹56.07 ₹22.43 more oil, ₹3.04 less wax ₹19.39 (18.4%)
Woody Oud ₹4.53 ₹40.78 ₹54.37 ₹67.97 ₹27.19 more oil, ₹3.04 less wax ₹24.15 (21.5%)
Lavender ₹5.22 ₹46.99 ₹62.65 ₹78.31 ₹31.33 more oil, ₹3.04 less wax ₹28.29 (23.9%)
Autumn ₹5.43 ₹48.85 ₹65.14 ₹81.42 ₹32.57 more oil, ₹3.04 less wax ₹29.53 (24.5%)

Read the last column as "what the load change adds to each candle's materials". With Citrus Lemon it is ₹13.95; with Autumn, ₹29.53. The percentage in brackets is the rise in wax-plus-oil cost for the candle: 14.4% for Citrus Lemon, 23.9% for Lavender. The dearer the oil, the more a load step costs, and the more it is worth finding the lowest load that performs. Autumn's row is shown for comparison only at 6%: its page states 7–11%, so 6% is below its own range.

Argued against our own interest: if your 6% candles already throw well, moving to 10% adds ₹28.29 of Lavender to every candle for a change you may not be able to smell. We sell the oil. Test 6%, 8% and 10% side by side after a proper cure, and choose the lowest load that does the job; how to find it is in our minimum-load guide, and what dropping from 10% to 8% saves across a business is in the load-savings guide.

What changes in a 100-candle order

At 100 candles, the load change is 600 g of wax you don't need and 600 g of oil you do.

Worked example: 100 candles of 150 g in the standard jar, CSI 464 and Lavender, packs as listed on 26 September 2026. Allowances for pitcher residue, top-ups and rejects come from the pack rounding here; how to size them properly is in I'm Making 100 Candles in 200 ml Jars — How Do I Calculate the Total Wax and Fragrance Oil I Need Without Making Too Much?.

100 × 150 g candles · 6% versus 10% · CSI live pricing, 26 September 2026
The wax order does not change; the oil order does
Item At 6%: need At 6%: buy At 10%: need At 10%: buy
Luxury Soy Wax CSI 464 14.1 kg 10 kg + 5 kg, ₹7,611.00 (0.9 kg spare) 13.5 kg 10 kg + 5 kg, ₹7,611.00 (1.5 kg spare)
Lavender Fragrance Oil 900 g 1 kg, ₹5,221.00 (100 g spare) 1.5 kg 1 kg + 500 g, ₹7,841.00 (no spare)
Order total ₹12,832.00 ₹15,452.00

The order grows by ₹2,620.00, the price of the extra 500 g bottle. Measured by what the candles actually consume, the rise is ₹2,828.00: materials used go from ₹11,853.00 to ₹14,681.00 per hundred. Note the 10% column leaves no spare oil, so a single re-pour or a heavy hand on the scale leaves you short; buy the extra 100 g or confirm stock on WhatsApp before you start. The wax order does not move at all, because 15 kg covers both 14.1 kg and 13.5 kg.

Where the money really is
Per 150 g candle, the wax you save by going to 10% is ₹3.04. Per 100 candles that is 600 g of CSI 464, about ₹304.44. It will never pay for the oil. Plan a load change as an oil purchase, not a wax saving.

Oils and wax priced for 6%, 8% and 10%

Five oils whose pages state a candle load, every size in stock on 26 September 2026, ordered by 1 kg per-gram price, low to high, and the wax whose 10% ceiling frames this guide. The candle columns are whole 150 g candles per bottle: 9 g of oil at 6%, 12 g at 8%, 15 g at 10%. Chosen on stated load, notes, price and stock, not on performance: CSI publishes no throw ratings.

citrus · the lowest per-gram oil of the five picks
Citrus Lemon Fragrance Oil
The page lists "zesty lemon and lime top notes, bright grapefruit and orange heart, and a tangy mandarin finish" and states "candles (6-10%)". It is the cheapest per gram of these five, so a load change moves its cost least. Citrus-led scents are often the ones makers push towards 10%; test whether yours needs it. Limitation: the 15 g is ₹5.43 per gram, almost twice the 1 kg rate.

The page lists "citrus and spice top notes opening into rich oud and patchouli heart, settling into warm woody notes, amber, and musk", states "candles (6-10%)" and advises curing soy candles 48–72 hours before burn testing. Its 100 g, 500 g and 1 kg all work out at ₹4.53 per gram, so a 100 g test bottle costs the same per gram as bulk. Limitation: heavier base notes tend to show their strength later in the cure; judge at your usual cure day, not the next morning.

The page lists "fresh lavender top notes, herbal green mid notes, and soft musk base", states "Recommended fragrance load 6-10% for candles" and describes it as "IFRA-certified" (the page's wording; documentation on request). Every cost figure in the diagram uses it. Limitation: at ₹5.22 per gram at 1 kg it is the second-dearest of these five, so the 6% → 10% step costs ₹31.33 more oil per 150 g candle.

The page lists "crisp red apple, cinnamon leaf, and orange zest top notes, golden maple, clove bud, and nutmeg middle notes, and warm oak, amber, and vanilla base" and states "Recommended fragrance load 7-11% for candles". In CSI 464 the wax's 10% governs, and 6% sits below the page's own range, so test 7%, 8.5% and 10% instead. Limitation: the dearest per gram of the five; 50 g to 1 kg are all ₹5.43 per gram, so bulk saves nothing per gram.

wax · the 10% ceiling in this guide
Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles
The page states "Fragrance Load Up to 10%" and "Pour Temperature 80°C – 90°C". So 10% is the ceiling here, not a target: under the two-ceilings rule, the lower of the wax and oil maximums governs. Moving from 6% to 10% cuts the wax in a 150 g candle from 141 g to 135 g, ₹3.04 less wax at the 10 kg price. If you want to test above 10% with an oil whose page allows it, CSI 468 and Luxury Soy Wax Chunks state up to 13%, but that is a wax change, not a load change. Limitation: flat ₹0.51 per gram from 1 kg to 10 kg, so a bigger bag saves nothing per gram.
Size Price Per gram Candles at 138 g wax (150 g at 8%)
500 g ₹260.00 ₹0.52 3 candles (138 g each)
1 kg ₹507.40 ₹0.51 7 candles
5 kg ₹2,537.00 ₹0.51 36 candles
10 kg ₹5,074.00 ₹0.51 72 candles
At 100 candles of 150 g, the load change does not change the wax bags you buy: 15 kg covers both 6% and 10%. Buy CSI 464 — from ₹260.00
When the right purchase is nothing: if you only want to know how much wax goes in each jar at 10%, you already have the answer, 135 g in a 150 g candle, and need nothing from us. Buy oil when you have decided the load, and in the size that matches the candle count in the columns above.

What a load change can touch besides grams

Grams and rupees are the arithmetic. The burn is the test.

This guide stays with the arithmetic; which load smells best is a separate argument, and the answer is always your own side-by-side test. But three things besides grams can move when the load does, and you should check them before a batch.

1. The ceilings

Every load you test must sit inside both the oil page's stated candle load and the wax page's stated maximum. CSI 464 states up to 10%; CSI 468 and Luxury Soy Wax Chunks state up to 13%. The five picks above all state 10% or 11% as their candle maximum, so 10% is as far as this guide goes. These are formulation limits, not regulatory limits, and a maximum is not a recommendation.

2. The wick

More oil in the same wax can change how the flame and pool behave. Some makers find they need a different wick at a higher load, some don't; the only way to know is to burn the 10% candles with the wick that passed at 6% and one size either side. The Eco range is C1 and C2; for why load and wick interact, see our wick-and-load guide. No CSI listing states an inside diameter, so a wick is always a test, not a spec.

3. The cure and the surface

Several CSI oil pages, Woody Oud's among them, advise curing soy candles 48–72 hours before burn testing; many makers wait longer before judging throw. Compare loads at the same cure age. And look at the top and sides: at higher loads some wax and oil pairs show sweating or a softer surface, which is a reason to step back down, not to push on.

Mistake: changing the load and the jar in the same week. Why it fails: the jar changes the fill weight and the wick; the load changes the split and the cost. If the new candle burns badly you cannot tell which change caused it. Fix: one variable per test round. A switch of wax instead of load is handled in I'm Switching From Soy Wax to Coconut-Soy Wax — Do I Need to Recalculate the Fill Weight for My Existing Candle Jars?; a jar change in I'm Changing My Candle Jar to Reduce Costs — Which Parts of My Existing Formula Need to Be Retested Even If the Wax and Fragrance Remain Unchanged?.

The CSI principle
Start every recipe from the jar's fill weight, then split it. Never start from the wax.
A load change moves grams between wax and oil inside a fixed total. The jar does not notice; your oil bill does.
"Going from 6% to 10% doesn't need a bigger jar or more wax. It needs 6 g more oil per candle, and a good reason to pay for it."

Why trust this guide

CandleMakingSuppliesIndia sells the oils and wax priced here and does not sell finished candles. A higher load sells more oil, and this guide still tells you to test whether you need it and to choose the lowest load that performs.

Every price and per-gram figure was verified on CSI's live store on 26 September 2026; every size in the pick tables was in stock on that date. Notes and load wording are quoted from the oil pages, and wax ceilings from the wax pages; the worked candle sizes of 120 g and 180 g are the listings' own figures, used as examples, not as weighed fills.

The 150 g planning figure, the standard-jar height effect and the 100-candle order are worked examples; the 0.86–0.9 factor is a rule of thumb; the advice to test 6%, 8% and 10% and to change one variable at a time is editorial judgement.

Frequently asked questions

If I increase fragrance load, do I use less wax in the jar?
Yes. The jar holds the same total weight to your fill line, so more oil means less wax. In a 150 g candle, 6% is 141 g wax + 9 g oil and 10% is 135 g wax + 15 g oil.
How do I calculate wax and fragrance oil for a candle at 10%?
Oil = finished candle weight × 0.10; wax = finished weight − oil. For a 150 g candle: 15 g of oil and 135 g of wax. Start from the jar's weighed fill weight, not from the wax.
Is fragrance load a percentage of wax weight or total weight?
Both conventions exist. CSI's guides use total candle weight. At 10% in a 150 g candle, total weight gives 15 g of oil; 10% of the wax weight gives about 13.6 g, which is 9.1% of the finished candle. Pick one and use it consistently.
How much more does a candle cost at 10% fragrance load than at 6%?
Per 150 g candle it is 6 g more oil and 6 g less wax. With CSI 464 and Lavender at 1 kg prices, materials rise from ₹118.53 to ₹146.81, ₹28.29 more. With Citrus Lemon the rise is ₹13.95.
Will a higher fragrance load overfill my candle jar?
Not if you split the same fill weight. It will if you add oil on top of the old wax weight: 150 g of wax + 15 g of oil is 165 g, about 0.6 cm higher in a standard 200 ml jar, and only 9.1% load.
Can I use 10% fragrance oil in soy wax?
Only if both pages allow it. Luxury Soy Wax CSI 464 states up to 10%; the oil page's candle load must also reach 10%. Lavender, Woody Oud, Roasted Coffee and Citrus Lemon state 6–10%. A maximum is not a target: test 6%, 8% and 10% and burn-test the wick.
Your load change, done right
Same fill weight. 6 g less wax. 6 g more oil.
Split your jar's weighed fill weight at the new load, pour one jar to your line and weigh it, then burn-test 6%, 8% and 10% side by side after a proper cure. Buy the oil for the load that wins, in the size that matches your candle count.

About this guide: part of CSI's jar-size, capacity and wax-quantity cluster. It answers whether moving from 6% to 10% fragrance load changes the wax per jar (the total stays the same; wax falls and oil rises), gives the grams at 6%, 8% and 10% for four candle sizes, separates total-weight from wax-weight load conventions, and costs the change per candle and per 100 candles for five CSI oils.
