Yes — and this is the forgiving direction of the mistake. Under-scenting adds nothing you have to undo; it simply leaves a debt of oil you can pay in one top-up. On 5 kg of wax that debt is 50 g per percentage point, so 5% to 8% is 150 g. What stops you is not the maths. It is the load ceiling printed on your wax's own page.
+150 g
of the same oil to take 5 kg of wax from 5% to 8% of wax weight · 50 g per percentage point · from ₹212.40 to ₹410 per point depending on the oil · CSI live pricing, September 2026
Quick answers — read this first
Can I add fragrance to a batch that is already scented? Yes. Remelt to the temperature your wax page states for adding fragrance, weigh in the shortfall, stir for two full minutes and pour. You add oil only — no extra wax, which is what makes this the cheap direction of a load error.How much am I short? Top-up = wax × (target load − actual load). On 5,000 g going from 5% to 8% of wax weight that is 5,000 × 0.03 = 150 g. Every percentage point on a 5 kg batch is exactly 50 g, which is one 50 gm bottle.
What stops me going higher? Your wax's stated ceiling. On Luxury Soy Wax Chunks (stated up to 13% of total wax weight) 5 kg holds up to 650 g, so you have 400 g of headroom. On CSI 464 (stated up to 10%) the cap is 500 g — only 250 g of headroom.
Do I have to correct it at all? No, and this is the question worth asking first. A 5% candle is a working candle, not a faulty one. If the batch is already poured and curing, selling it as a lighter line costs ₹0 and needs only a burn test and honest labelling.
The short answer
Back out the real load before you buy anything: weigh the batch, subtract the wax you weighed in, and the remainder is the oil that actually went in. A batch reading 5,250 g on 5,000 g of wax holds 250 g of oil — 5% of wax weight, 4.76% of the finished candle.
Then top up oil only, never oil plus wax: 150 g of the same oil, which is ₹810 in Lavender as a 100 gm plus a 50 gm bottle, ₹660 in Jasmine, ₹554.60 in British Rose.
Check the ceiling, then retest: the top-up must land inside what your wax page states, and the corrected batch is a new formula — two heat cycles, more oil per candle and 27 candles instead of 26. Burn three before you sell any.
In this guide
The ladder is linear because the wax never changes — only the oil does. That is the whole reason an under-scented batch is cheaper to fix than an over-scented one: you buy 150 g of oil, not 2.5 kg of wax, and the batch weight barely moves. The two shaded rules at the bottom are the only hard limits on this page.

Straight answer
Can I remelt 5 kg of under-scented soy wax and add the fragrance I missed?
Yes, recoverable in principle — and unlike an over-load, the correction adds nothing you have to accommodate. Weigh the batch first: if it reads 5,250 g on 5,000 g of wax, the oil that went in is 250 g, which is 5% of wax weight. The shortfall is wax × (target − actual) = 5,000 × 0.03 = 150 g, so each percentage point on this batch is exactly 50 g of oil — conveniently, one 50 gm bottle. At Lavender's listed 100 gm rate of ₹5.40 per gram, 150 g is ₹810; the same top-up is ₹660 in Jasmine and ₹554.60 in British Rose. Before you buy, check the ceiling stated on your wax: Luxury Soy Wax Chunks state up to 13% of total wax weight, so 5 kg tops out at 650 g; CSI 464 states up to 10%, capping you at 500 g; Eco Soy CSI 400 states no load at all. Then remelt to the wax page's stated add band, weigh the oil in, and stir a full two minutes. The batch grows from 5,250 g to 5,400 g — 27 whole 200 g candles instead of 26 — and oil per candle rises from 9.62 g to 14.81 g, or ₹51.92 to ₹80.00. What you cannot do is assume the throw: the batch now has two heat cycles and a load it has never been burned at. Three cured jars settle that; a calculator does not.
One line: top-up = wax × (target load − actual load), which is 150 g here, ₹810, and one burn test away from being sellable.
Topping up today? On a 5 kg batch, one 50 gm bottle is exactly one percentage point — from ₹212.40 for British Rose or Eucalyptus Spearmint to ₹410 for Vanilla Bean. Buy the same oil, not a similar one.

50 g per percentage point: the only number you need
On a fixed weight of wax, load is linear. That is the entire reason this rescue is easy and the over-load rescue is not.
When you have too much oil, the wax is the variable and it sits in the denominator — which is why correcting downwards needs a disproportionate amount of wax and grows the batch. When you have too little oil, the wax is fixed and the oil is the variable, so the relationship is a straight line. One percentage point of load equals 1% of the wax weight in oil: 10 g on 1 kg, 50 g on 5 kg, 100 g on 10 kg. Nothing compounds and nothing has to be recalculated as you go.
1
Weigh the batch and back out the real loadPut the pot on a weighing scale, tare it and read the total. Subtract the wax you weighed in. A reading of 5,250 g on 5,000 g of wax means 250 g of oil went in, not the 400 g you intended. Do not trust the bottle — trust the scale, because the bottle only tells you what is left, and part-used bottles are where this mistake starts.
2
State the convention out loud250 g of oil in 5,000 g of wax is 5% of wax weight and 4.76% of the finished candle. Both are true statements about the same pot. CSI's wax pages express load as a percentage of total wax weight, so that is the convention used throughout here; write it on the batch sheet so the next person to read it does not recalculate in the other one.
3
Multiply, don't estimateTop-up = W × (L2 − L1) = 5,000 × (0.08 − 0.05) = 150 g. If you prefer to work in bottles: three percentage points on 5 kg is three 50 gm bottles, or one 100 gm plus one 50 gm, which is the cheaper of the two on every oil in the table below.
4
Check it against the ceiling before you orderYour target plus the oil already in the pot must sit inside what your wax page states. 400 g in 5,000 g of wax is 8% — comfortably inside the 13% Luxury Soy Wax Chunks state and inside the 10% CSI 464 states. If your target had been 12%, CSI 464 would have refused it on its own page.
5
Reheat into the stated add band, then weigh the oil inBring the batch back to a clear, uniform melt and up to the band the page states for adding fragrance — 80–90°C on Luxury Soy Wax Chunks, 80–90°C (85°C) on Eco Soy CSI 400, 50–53°C melt and 58–60°C pour on CSI 468. Weigh the 150 g into a separate container first, add it in one go, and stir for a full two minutes — the instruction the Eco Soy CSI 400 page gives explicitly and good practice on any soy.
6
Recount, relabel, retestThe batch is now 5,400 g — 27 whole 200 g candles, one more than before. Write the new formula on the sheet as its own line rather than editing the old one: you want a record that this batch is 5,000 g wax + 400 g oil added in two stages, because that is what you will need if the burn test surprises you. Then pour three test jars, cure with the rest, and burn them.
The ladder on 5 kg of wax · CSI live pricing, September 2026
Every load you could correct to, what it costs and what it does to the candle count
| Target load (% of wax weight) | Oil in the batch | Top-up from 250 g | Cost in Lavender at ₹5.40/g | Batch weight | Whole 200 g candles | Same load as % of candle |
|---|---|---|---|---|---|---|
| 5% (where you are) | 250 g | — | ₹0 | 5,250 g | 26 | 4.76% |
| 6% | 300 g | 50 g | ₹270 | 5,300 g | 26 | 5.66% |
| 7% | 350 g | 100 g | ₹540 | 5,350 g | 26 | 6.54% |
| 8% (your target) | 400 g | 150 g | ₹810 | 5,400 g | 27 | 7.41% |
| 9% | 450 g | 200 g | ₹1,080 | 5,450 g | 27 | 8.26% |
| 10% — CSI 464's stated ceiling | 500 g | 250 g | ₹1,350 | 5,500 g | 27 | 9.09% |
| 13% — Chunks and CSI 468's stated ceiling | 650 g | 400 g | ₹2,160 | 5,650 g | 28 | 11.50% |
Worked out above: oil at each load = 5,000 g × load. Top-up = that figure minus the 250 g already in the pot. Cost = top-up × ₹5.40, the listed per-gram rate of the Lavender Fragrance Oil 100 gm bottle (₹540 ÷ 100 g). Batch weight = 5,000 g of wax plus the oil. Candle counts are whole 200 g fills before any pouring loss. The right-hand column restates the same load as a share of the finished candle, for readers whose recipe sheet uses that denominator.
Do not "make it up" with a different oil. If you are 150 g short of Lavender and you have 150 g of Sandalwood on the shelf, topping up with the Sandalwood does not correct a load error — it creates a blend at roughly 62:38, which is a new fragrance nobody has smelled in this wax, at a load nobody has burned. You now have two unknowns instead of one. Buy 150 g of the oil that is already in the pot. If the oil is genuinely unavailable, the honest routes are to correct to a lower target you can actually reach, or to keep the batch at 5% and sell it as a lighter line — both are covered further down.
Where the top-up has to stop
This is the one place an under-load rescue can go wrong, and it goes wrong in the same direction every time: the maker who discovers they are at 5% decides to "make up for it" and lands at 12% or 14%. Diluting a batch downwards can never breach a ceiling. Topping up can, and the ceiling is a property of the wax, not of the oil.
A stated load is the maximum quantity of oil the wax has been formulated to hold in solution. Past it, the surplus does not bind — it migrates during cooling and cure, sweats to the surface, and gives you a weaker candle for more money. The mechanism is set out in can too much fragrance oil make a candle smell weaker, and the consequence in a finished jar is in why your candle is sweating fragrance oil. The numbers below are the ceilings CSI's wax pages actually publish, converted to grams for 5 kg.

How much headroom each wax gives you above the 250 g already in the batch
| Wax | Stated fragrance load | Ceiling on 5 kg | Headroom above 250 g | Stated add temperature | 5 kg pack price |
|---|---|---|---|---|---|
| Luxury Soy Wax Chunks | 8% to 13% of total wax weight; 10% recommended | 650 g | 400 g | Add at 80–90°C; pour 70–80°C | ₹2,995 |
| Luxury Soy Wax CSI 464 | Up to 10% | 500 g | 250 g | Page states melt and pour both 80–90°C | ₹2,537 |
| Premium Coconut Soy CSI 468 | Up to 13% | 650 g | 400 g | Melt 50–53°C; pour 58–60°C | ₹3,185 |
| Eco Soy CSI 400 | Not stated on the page | No published figure | Unknown — test it | Add at 80–90°C (85°C), stir 2 minutes | ₹1,996 |
| Natural Soy Pearl Wax | Not stated on the page | No published figure | Unknown — test it | Not stated | ₹2,124 |
| Soy Pillar Wax | Not stated on the page | No published figure | Unknown — test it | Not stated | ₹3,000 |
"Not stated" is information, not permission
Three of the six waxes above publish no maximum load. That does not mean they hold more, and it does not mean they hold less — it means you have no published figure to correct towards, so the number you top up to has to be one you have burn-tested yourself in that wax and that vessel. The safe move on an unstated wax is to correct to the load you have already proven, not to the load you read about somewhere. Where a fragrance-oil page happens to state a candle load of its own — many CSI oil pages say things like "up to 10% for soy wax" or "6-10% for candles" — treat it as the oil supplier's guidance alongside the wax's, and work to the lower of the two. Documentation for a specific oil, including the SDS where one exists, is supplied on request via WhatsApp.What 150 g of the same oil costs
Because the top-up is small, the bottle ladder matters more than the per-kilo price. On every oil below, one 100 gm bottle plus one 50 gm bottle costs less than three 50 gm bottles — except Lavender, where the two routes come to the same ₹810 — and a 500 gm bottle only makes sense if you are about to pour again. The cards give the full ladder for the three oils most likely to be sitting half-used on an Indian maker's shelf.
1
The top-up · 150 g for ₹810
Lavender Fragrance Oil
The most commonly under-dosed oil in India, simply because it is the most commonly poured. Its page states a recommended fragrance load of 6-10% for candles and 10-15% for wax melts — so an 8% target sits inside the oil's own guidance as well as the wax's. One 100 gm bottle (₹540) plus one 50 gm bottle (₹270) is ₹810 for the 150 g; three 50 gm bottles would be the same 150 g for ₹810 as well, so take whichever you will store more sensibly. Note the 500 gm bottle at ₹2,620 works out at ₹5.24 per gram against ₹5.40 at 100 gm — worth it only if the next batch is already planned. One CSI customer, Akansha, writes that "hot throw is also very good after burn candle".
| Size | Price | Per 100g | 200g candles @ 8% of wax wt |
|---|---|---|---|
| 15 gm | ₹105.02 | ₹700.13 | ≈1 |
| 50 gm | ₹270 | ₹540 | ≈3 |
| 100 gm | ₹540 | ₹540 | ≈6 |
| 500 gm | ₹2,620 | ₹524 | ≈33 |
| 1 kg | ₹5,221 | ₹522.10 | ≈67 |
₹810 for the 150 g this batch is short · ₹270 per percentage point Buy Lavender Fragrance Oil
2
The top-up · 150 g for ₹554.60
British Rose Fragrance Oil
The cheapest 150 g on this page, and the one whose page is most useful to an under-load rescue: it states vanillin content 0% with no discolouration or yellowing in wax, so a second heat cycle and a higher load will not introduce a colour problem on top of a scent one. A 100 gm bottle is ₹342.20 and a 50 gm ₹212.40, making ₹554.60 for the 150 g and ₹212.40 per percentage point — the lowest per-point figure in the range covered here. One CSI customer, Emma Bechara, writes that "you can go for the minimum percentage in candle still it will give amazing smell", which is a fair reminder that a lower load is not automatically a failure.
| Size | Price | Per 100g | 200g candles @ 8% of wax wt |
|---|---|---|---|
| 15 gm | ₹94.40 | ₹629.33 | ≈1 |
| 50 gm | ₹212.40 | ₹424.80 | ≈3 |
| 100 gm | ₹342.20 | ₹342.20 | ≈6 |

| 1 kg | ₹3,068 | ₹306.80 | ≈67 |
₹554.60 for 150 g · ₹212.40 per percentage point Buy British Rose Fragrance Oil
3
The top-up · 150 g for ₹774.08
Sandalwood Fragrance Oil
A base-heavy oil, which matters to this particular rescue: heavier, less volatile materials are the ones most likely to still be there after a second heating, so a sandalwood batch is a better candidate for a top-up than a bright citrus. Its page states up to 10% for soy wax and up to 6% for paraffin, a cure of 48-72 hours for soy, a stated flashpoint of 203°C and 0% vanillin — no discolouration. A 100 gm bottle is ₹502.68 plus a 50 gm at ₹271.40, so ₹774.08 for 150 g. Note that its 100 gm, 500 gm and 1 kg bottles all list at the same ₹5.0268 per gram, so there is no saving in buying a bigger bottle than the batch needs.
| Size | Price | Per 100g | 200g candles @ 8% of wax wt |
|---|---|---|---|
| 15 gm | ₹93.22 | ₹621.47 | ≈1 |
| 50 gm | ₹271.40 | ₹542.80 | ≈3 |
| 100 gm | ₹502.68 | ₹502.68 | ≈6 |

|---|---|---|---|---|---|
| British Rose | ₹212.40 | ₹342.20 | ₹554.60 | ₹212.40 | 0% vanillin, no discolouration; flashpoint 192°C |
| Eucalyptus Spearmint | ₹212.40 | ₹354 | ₹566.40 | ₹212.40 | Up to 10% for soy wax, up to 6% for paraffin |
| Roasted Coffee | ₹230 | ₹390 | ₹620 | ₹230 | 6-10% for soy wax candles, cure 48-72 hours |
| Jasmine | ₹230 | ₹430 | ₹660 | ₹230 | Up to 10% for soy wax, up to 12% for wax melts |
| Sandalwood | ₹271.40 | ₹502.68 | ₹774.08 | ₹271.40 | Up to 10% for soy wax, up to 6% for paraffin |
| Lavender | ₹270 | ₹540 | ₹810 | ₹270 | 6-10% for candles, 10-15% for wax melts |
| Vanilla Bean | ₹410 | ₹790 | ₹1,200 | ₹410 | Up to 10% for soy wax, up to 6% for paraffin |
The spread is worth noticing: the most expensive top-up on this table is 2.16 times the cheapest, ₹1,200 against ₹554.60. Across the whole batch that difference is ₹645.40, or about ₹23.90 on each of 27 candles. It is a real number, but it is not a reason to substitute an oil — it is a reason to know your per-point figure before the next batch, so that a three-point error never comes as a financial surprise.
Adding oil to wax that is already scented
Mechanically this is not a rescue technique. It is the same step you already did, done twice — which is exactly why it is safe and exactly why it is not free.
There is nothing exotic about adding fragrance to a batch that already contains some. The oil dissolves into the melted wax on the second pass the way it did on the first, provided the wax is genuinely liquid, genuinely up to the stated add temperature, and genuinely stirred. What changes is not the chemistry of the top-up but the history of the batch, and there are exactly three things to be honest about.
What a second heating changes, and how you find out
Three real effects, separated from the things people worry about that the arithmetic already covers
| What changes | Why | What it costs | How you find out |
|---|---|---|---|
| Heat history of the whole batch | The original 250 g of oil now goes through two full heat cycles instead of one; the new 150 g goes through one | Unknown until measured — no product page states an effect | Burn three cured jars against your last batch at the same load, if you have one |
| The formula on your sheet | 5% is not 8%; a two-stage addition is not a single addition | Nothing, if you write it down. A lost recipe, if you do not | The batch sheet — record "250 g + 150 g, second addition at 85°C" |
| The wick qualification | Oil per candle goes from 9.62 g to 14.81 g and fill weight is unchanged, so the pool behaves differently | Three test candles and 14 days | Time to a full melt pool, flame height, soot, throw at 30 and 120 minutes |
| Candle count and costing | Batch grows 5,250 g → 5,400 g; oil cost per candle rises ₹51.92 → ₹80.00 | ₹810 of oil, one more vessel, one more wick | Reweigh the batch and recount before you pour |
| The wax's ceiling | Unchanged — you are moving towards it, not past it, at 8% on any of these waxes | ₹0 | The wax product page, in grams: 8% of 5,000 g is 400 g |
Do not add the oil to wax that is merely warm. The commonest failure in this rescue is impatience: the batch is soft, it looks liquid at the surface, and 150 g of oil goes in at 55°C. Below the stated add band the oil disperses rather than dissolves, and you get a batch that reads 8% on the scale and pours at three different loads across 27 jars — visible as cloudy streaks, an oily film on the first candles to set, and a wick that struggles in some jars and not others. Bring the batch to a clear, uniform melt and to the page's stated band before the bottle comes anywhere near it: 80–90°C on Luxury Soy Wax Chunks, 80–90°C (85°C) on Eco Soy CSI 400, 58–60°C at pour on CSI 468. Use a pen thermometer in the wax, not against the pot wall. The full reasoning on add temperature is in best temperature for adding fragrance oil to soy wax.
The CSI principle
Under-scenting costs you oil. Over-correcting costs you the batch.
A 5% candle burns, throws and sells — it is simply quieter than the one you specified. The only way to turn that into a real loss is to chase the missing three points past the ceiling your wax publishes, where the surplus stops dissolving and starts sweating. Correct to the number on the page, not to the number your disappointment suggests.
One 50 gm bottle is one percentage point on 5 kg. Keep a spare 50 gm of every oil you pour in volume and a three-point shortfall becomes a thirty-minute fix instead of a week's delay. For recurring volumes above the listed 1 kg bottle, pricing is quoted on WhatsApp.

If the batch is already in jars
Everything above assumes the wax is still in the pot, or has only just been poured and has not cured. If the candles are poured, set and curing, the top-up is still arithmetically identical — but the job around it changes completely, and two new costs appear that have nothing to do with oil.
The first is the wicks. A wick that has been set into cured wax and pulled out is not a wick you put into a candle you sell: it has been coated, its tab is set and its position is disturbed. Budget a fresh one per candle — Eco Candle Wicks Thin (C1) are ₹5.90 each in every pack size from 10 to 1,000 — plus a fresh sticker at ₹2.50 from the 40-sticker sheet. The second is loss: wax left in the jars, on the scraper and in the melter never reaches a candle, and no product page states a figure for it. Weigh your own — batch weight before pouring minus the total of every filled jar — and use that number from then on.
The jars survive; the labels and the wicks do not. Glass is the expensive part of a poured candle and it is fully recoverable: warm the candle until the plug releases, lift it out whole, and clean the jar. A 120 gm Amber Shiny Glass Jar is ₹47.20, so 26 of them are ₹1,227.20 you keep rather than rebuy — several times the ₹810 of oil the correction needs. What you should not keep is the batch label. Print a new one with the corrected formula and the new pour date, because the cure clock restarts from the day you repour, not from the original pour. The detailed version of this job at 50 candles is in already poured 50 candles at 5% instead of 8%.
The case for not correcting it at all
Worth stating plainly, because it is the route makers reach for last and should often reach for first: an under-scented candle is not a defective candle. Nothing in it is unstable, nothing will sweat, nothing will fail safely-relevant checks that a correctly loaded candle would pass. It has less oil in it than you intended, which makes it a quieter candle and a cheaper one to have made.

| Keep it at 5% and label it honestly | ₹0 of material; one burn test | 26 candles at a lower load and a lower cost per candle (₹167.12 against ₹190.93 of wax and oil) | Nothing on the label or the order specifies a load, and a lighter scent suits the range |
The middle route is the one experienced makers choose surprisingly often, because it converts a mistake into information. Split the batch in two, correct one half, pour both into identical vessels with identical wicks, cure them together and burn them side by side. You will have spent ₹405 and learned whether three percentage points of this particular oil in this particular vessel is worth ₹28.08 a candle — which is a question you were going to have to answer eventually anyway. The method for a clean side-by-side is in how to compare two fragrance oils using a controlled burn test.
Too little oil is a bill you can still choose whether to pay. Too much is a bill that has already been charged.

The weighing habit that ends this
Short, because you have a batch waiting. Under-dosing almost always comes from one of two places, and both are solved at the scale rather than at the pot.
The first is pouring from the bottle into the melter. Done that way, the only record of the dose is how heavy the bottle felt, and a part-used bottle feels exactly like a full one when you are in a hurry. Weigh the oil into a separate cup on a ₹354 scale and read the number before it goes anywhere near the wax. The second is a target written as a percentage rather than as grams. "8%" invites a calculation at the worst possible moment; "400 g" does not. Write the batch sheet in grams — wax 5,000 g · oil 400 g · load 8% of wax weight · add 80–90°C · stir 2 min · pour 70–80°C — and the percentage becomes a label rather than a live sum.
Keep one 50 gm bottle of every production oil
On a 5 kg batch, a single 50 gm bottle is exactly one percentage point of load. Keeping one spare bottle of each oil you pour in volume — from ₹212.40 — turns a three-point shortfall from a week's delay into an afternoon's work, and it means you never face the temptation to top up with "something similar". The same bottle doubles as your cold-throw reference when you are deciding whether the batch on the bench smells like the one you sold last month.Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. We sell fragrance oil, so the self-serving advice on this page would be to top every under-scented batch up to the ceiling. Instead the page says three things that cost us sales: a 5% candle is a working candle, correcting half the batch teaches you more than correcting all of it, and topping up past your wax's stated ceiling wastes the oil you just bought.
Every price, bottle size and specification here comes from live CSI stock in September 2026 and links to the product page, where current pricing always takes precedence. Wax loads are quoted only where the wax page states them — 8% to 13% of total wax weight with 10% recommended for Luxury Soy Wax Chunks, up to 10% for CSI 464, up to 13% for CSI 468 — and Eco Soy CSI 400, Natural Soy Pearl Wax and Soy Pillar Wax state none, which we say rather than fill in. Fragrance-oil figures are the pages' own wording, including British Rose's stated 0% vanillin and 192°C flashpoint and Sandalwood's stated 203°C flashpoint; a flash point is a fire-safety property of the oil, not an instruction about when to add it, and we never convert a page's "> 93°C" threshold into a measurement. No CSI oil page states a shelf life or storage condition, so this page does not either.

Frequently asked questions
How much fragrance oil do I add to take 5 kg of soy wax from 5% to 8%?
150 g of the same oil. The formula is wax × (target load − actual load) = 5,000 × (0.08 − 0.05). On a 5 kg batch every percentage point is 50 g, so three points is three 50 gm bottles, or one 100 gm plus one 50 gm. That is ₹810 in Lavender, ₹660 in Jasmine and ₹554.60 in British Rose. You add no extra wax.
Do I need to add more wax as well when I top up the oil?
No — and adding wax would undo the correction. Wax is the denominator of the load, so adding it pushes the percentage back down. Top up oil only. The batch does grow slightly because oil has weight: 5,250 g becomes 5,400 g, which is 27 whole 200 g candles instead of 26. Order one more vessel, wick and sticker before you pour so you are not inventing a fill weight for the last jar.
Is it safe to reheat soy wax a second time to add fragrance?
Reheating to the temperature your wax page already states for adding fragrance is the same operation you performed the first time, and no CSI wax page limits the number of melts. Two rules: do not exceed the page's stated band to speed it up, and bring the wax to a clear, uniform melt before the oil goes in. What a second cycle does to throw is not published by anyone, so treat the corrected batch as untested and burn three cured jars before you sell.
How high can I go when correcting an under-scented batch?
To whatever your wax page states, and no further. On 5 kg: Luxury Soy Wax Chunks state up to 13% of total wax weight, so 650 g; CSI 468 also states up to 13%; CSI 464 states up to 10%, so 500 g. Eco Soy CSI 400 states nothing, so there is no published ceiling to correct towards — only a load you have tested yourself. Stated loads are formulation limits, not regulatory limits.
Can I use a different fragrance oil to make up the shortfall?
You can physically, but it is not a load correction — it is a new blend. Topping 250 g of one oil up with 150 g of another gives a roughly 62:38 mixture nobody has smelled in this wax, at a load nobody has burned, so you have replaced one known problem with two unknowns. Buy the oil that is already in the pot. If it is unavailable, correct to a lower target you can reach with what you have, or keep the batch at 5% and label it as the lighter line it is.
Will a 5% candle actually smell of anything?
Usually yes, and several things matter more than the last three percentage points. A full 14–21 day cure, a wick sized to open the melt pool to the glass in two to three hours, and a base-heavy oil all move perceived strength more than a small load increase does. One CSI customer writes of British Rose that "you can go for the minimum percentage in candle still it will give amazing smell". Burn one cured jar before you decide the batch is too quiet — you may be correcting a candle that did not need it.
Pay the oil debt, then prove it
150 g of the same oil, one clean remelt into the stated add band, two minutes of stirring — and three cured jars before anything ships.

Fragrance-page wording as published: British Rose vanillin content 0% with no discolouration or yellowing in wax, flashpoint 192°C; Sandalwood up to 10% for soy wax, up to 6% for paraffin, cure 48-72 hours for soy, flashpoint 203°C, 0% vanillin; Lavender 6-10% for candles and 10-15% for wax melts; Jasmine up to 10% for soy wax and up to 12% for wax melts; Eucalyptus Spearmint up to 10% for soy, up to 6% for paraffin; Roasted Coffee 6-10% for soy wax candles, cure 48-72 hours; Vanilla Bean up to 10% for soy wax, up to 6% for paraffin. Assumptions labelled as such: the batch is 5,000 g of wax plus 250 g of oil, weighed; load is calculated as a percentage of total wax weight to match CSI's wax-page wording, with the finished-candle equivalent shown alongside; candles are whole 200 g fills before any pouring loss; the ₹5.40 per gram used in the ladder is the Lavender 100 gm listed rate; pouring and remelt losses are not stated on any product page and are not estimated here — weigh your own. Cost per candle at 5% = (₹2,995 + ₹1,350) ÷ 26 = ₹167.12, where ₹1,350 is 250 g of Lavender bought as two 100 gm bottles and one 50 gm; at 8% = (₹2,995 + ₹1,350 + ₹810) ÷ 27 = ₹190.93.
