The candle that made your reputation was one specific combination of grams, degrees and days. Consistency is the discipline of reproducing all three when the room is busy, the bottle is new and somebody else is pouring. It is measurable, it is cheap, and almost none of it is about the fragrance oil itself.
2 g
of oil on a 16 g dose — nearly a full percentage point of fragrance load on a 200 g candle, and 2 kg of extra oil for every 1,000 candles if the error is systematic. This is the whole problem in one number · CSI live pricing, September 2026
Quick answers — read this first
What makes batches smell different? Almost never the oil. In order of frequency: an unweighed dose, a different add temperature, a different cure length, a new bottle that was never checked, and a wax or wick change nobody logged.How precise does the dose need to be? Within ±0.5 g on a 16 g dose. Two grams out is nearly a full point of load. Weigh it — no CSI page publishes a specific gravity, so millilitres cannot be converted to grams reliably for any oil in the range.
What about a new bottle of the same scent? Treat it as a change. Pour one jar at your standard recipe and cure it beside a jar kept back from the previous bottle. No CSI page publishes a lot number, so your retained jar is your reference.
What is the single biggest habit? One variable per batch. Change the wick or the load or the cure — never two. Two changes and a better candle teaches you nothing you can repeat.
The short answer
Fix the recipe in grams, not percentages: "184 g wax, 16 g oil, add at 85°C, pour at 75°C, cure 14 days" is a recipe. "8% at the right temperature" is a memory.
Weigh everything, zero the jug: wax and oil both, on a scale you trust. A 2 g dose error on a 200 g candle is nearly a whole point of load and 2 kg of oil per 1,000 candles.
Qualify every new bottle: one jar, standard recipe, cured beside a retained jar. Three CSI oils publish a flash point below 100°C — Neroli 85°C, Palo Santo 93°C, Gardenia 98°C — so check the figure before you set an add temperature.
In this guide
Load here is calculated as oil ÷ finished candle with the wax held at 184 g, which is what actually happens at the bench: the dose moves, the wax does not. A 14 g dose gives a 198 g candle at 7.07%; an 18 g dose gives a 202 g candle at 8.91%. The load band is a two-point spread produced entirely by a scale nobody zeroed.

Straight answer
How do you keep a fragrance consistent across commercial candle batches?
You convert the recipe into numbers that can be checked and then defend those numbers against a busy afternoon. Four controls do almost all the work. Weigh the dose: a 200 g candle at 8% is 184 g of wax and 16 g of oil, and 2 g out is nearly a whole point of load — millilitres will not do it, because no CSI fragrance-oil page publishes a specific gravity, so no volume-to-weight conversion is available for any oil in the range. Hold the temperatures the pages give you: Luxury Soy Wax Chunks states adding fragrance at 80–90°C and pouring at 70–80°C, Eco Soy CSI 400 states adding at 80–90°C with a 2-minute stir, and CSI 468 states melting at 50–53°C and pouring at 58–60°C. Qualify every new bottle with one jar poured to your standard recipe and cured beside a jar retained from the previous bottle — necessary because no CSI page publishes a batch or lot number, so your own retained jar is the reference. And change one variable per batch, because a batch with two changes in it teaches you nothing you can repeat. Then write it down: wax, wick, vessel, grams of oil, grams of wax, add temperature, pour temperature, cure days, and who poured it. Consistency is a records habit with a scale attached, and it costs about ₹708 in equipment.
One line: weigh the dose to ±0.5 g, hold the wax page's temperatures, qualify each new bottle against a retained jar, and change one thing at a time.
The two instruments that make a recipe reproducible: Candle Making Weighing Scale ₹354 and Pen Thermometer ₹354. Together ₹708 — less than one 100 g bottle of most oils.

Where variance actually comes from
When two batches disagree, the fragrance oil is the first thing blamed and almost the last thing responsible.
Rank the candidates honestly and the list is uncomfortable, because most of it is on your side of the transaction. This is good news: things on your side can be fixed for nothing.
Sources of batch-to-batch variance · ranked by how often they are the cause
What each one does to the candle, and what it costs to control
| Source | What it changes | How you detect it | Cost to control |
|---|---|---|---|
| Dose not weighed, or weighed on a coarse scale | Load moves by half a point per gram; throw and sweating both follow | Weigh one finished candle: it should be 200 g ± 2 g | ₹354 once |
| Cure length differs between batches | The single largest change in perceived strength; a day-4 candle is not a day-14 candle | Dated cartons; compare only same-age candles | ₹0 |
| Add temperature drifted | Incorporation and surface finish; the wax page states a band for a reason | Thermometer in the wax, not on the pot | ₹354 once |
| New bottle of the same scent, unchecked | Potentially nothing — but you have no way of knowing without a reference jar | One jar against a retained jar at day 14 | One candle per bottle |
| Wax changed, or two waxes mixed | Melt pool, throw and ceiling all change; a different wax is a different candle | Log the wax and pack on every card | ₹0 |
| Wick size or type changed | Pool diameter, and therefore release area — the biggest lever after cure | Timed burn to full pool, three jars | From ₹5.90 a wick |
| Vessel changed, same recipe | Diameter sets the pool; the same wick behaves differently in a wider jar | Note the internal diameter on the card | ₹0 |
| Stir time shortened when busy | Distribution through the wax; CSI 400's page asks for a full 2 minutes | A timer, not a count | ₹0 |
| Two variables changed at once | Destroys your ability to learn from the result | The card itself catches this | ₹0 |
| The oil itself | Possible, and the only item on this list you cannot control from the bench | Only detectable once everything above is fixed | A message to your supplier |
Notice the order. Nine controllable causes sit above the one you would complain about, and each of the nine is cheaper to fix than a conversation. That is also why a supplier conversation about consistency only becomes meaningful once the nine are under control: with a weighed dose, a logged temperature and a retained jar you can say "this bottle reads differently from the last one at day 14, same recipe" — which is a sentence anyone can act on.
The mistake: judging batches of different ages against each other. Perceived strength climbs through cure, so a four-day-old candle compared with a three-week-old one will always lose, and makers routinely conclude the new bottle is weak when the only difference is the calendar. Compare same-age candles only. Soy container candles are standardly cured 14–21 days; several CSI oil pages state a minimum of "48–72 hours for soy wax", which is the floor for a usable candle, not the point at which it is at its best. Date every carton on the day you pour it.
The 2 g problem
Fragrance load is a weight ratio, which makes the scale the most important instrument in the room. Hold the wax at 184 g and vary only the oil, and this is what the candle does.
Dose vs load · 184 g of wax held constant · target 16 g of oil for 8%
What each gram does to the load, the candle weight and a 1,000-candle month
| Oil dosed | Finished candle | Load | Off target by | Oil per 1,000 candles | At Verbena's ₹4.72 a gram |
|---|---|---|---|---|---|
| 14 g | 198 g | 7.07% | −0.93 points | 14 kg | ₹66,080 |
| 15 g | 199 g | 7.54% | −0.46 points | 15 kg | ₹70,800 |
| 16 g | 200 g | 8.00% | — | 16 kg | ₹75,520 |
| 17 g | 201 g | 8.46% | +0.46 points | 17 kg | ₹80,240 |
| 18 g | 202 g | 8.91% | +0.91 points | 18 kg | ₹84,960 |
Two lessons live in that table. The obvious one is the load spread: a two-point band from a four-gram window, which is wide enough to change throw, wide enough to push a marginal recipe into sweating, and narrow enough that nobody notices it happening. The less obvious one is the money: a systematic 2 g overdose on 1,000 candles is 2 kg of extra oil, ₹9,440 at Verbena's kilo price — a cost with no benefit attached, since the wax's ceiling has not moved and the extra oil is doing nothing useful.
Never dose by millilitres, teaspoons or "a good glug". Load is defined by weight, oils differ in density, and no CSI fragrance-oil page publishes a specific gravity, a viscosity or any physical property beyond flash point and solubility — so there is no published conversion from millilitres to grams for any of them. A volume measure that happens to be right for one oil will be wrong for the next. Weigh into the jug, on the scale, with the jug tared. If you must batch by volume for speed, calibrate by weighing what your measure actually delivers of that specific oil, and re-check when the bottle changes.
What the scale page does and does not tell you
The Candle Making Weighing Scale at ₹354 states that it "shows measurements in grams or ounces". It does not state a resolution or a maximum capacity, so if your work needs 0.1 g resolution — small votives at 8 g of oil, or blending trials — ask us before ordering rather than assuming. The same applies to the Pen Thermometer at ₹354: the page states no temperature range. Naming those gaps is more useful to you than implying a specification that is not published.Every new bottle is a new experiment
Not because bottles are unreliable, but because you have no documentary way to prove they are identical.
Here is the honest position, stated plainly: no CSI fragrance-oil page publishes a batch number, a lot number or batch-to-batch test data, and none publishes a shelf life, an expiry date or a storage instruction either. That is true of 107 pages out of 107. So "send me the same lot" is not a request the listing can answer, and the practical response is not suspicion — it is a protocol you own. A retained jar and a weighed dose give you a reference that does not depend on anybody's paperwork.
1
Date the bottle the day it arrives. Marker on the label: date in, size, scent. This is a records habit, not a shelf-life claim — no page states one — but it lets you say "the bottle we opened in July" instead of "the old one".
2
Finish the current batch on the current bottle. Never swap mid-batch. If 300 g is left and the batch needs 400 g, pour the batch smaller or open the new bottle for the next batch — a batch made from two bottles cannot be used as evidence about either.
3
Pour one qualification jar from the new bottle. Your standard vessel, your standard wax, your standard wick, 16 g and 184 g weighed, add and pour temperatures logged. One jar, not three — three is for testing a change, one is for confirming no change.
4
Cure it beside the retained jar from the previous bottle and check at day 14. Cold first, from about 20 cm, both lids off, without looking at the labels — have someone else swap them. Then burn both for two hours in the same room on different days and note the throw at three metres.
5
Record the verdict and retain a jar from the new bottle. Same, stronger, weaker, or different in character. If it reads differently, message us with the scent, both sizes, both dates and what you observed — that is an actionable report. Then the new jar becomes the reference for the next bottle, and the chain continues.
A retained jar is the cheapest quality system there is
One jar per bottle per scent. At the materials cost of a 200 g candle it is a small sum for the only physical evidence you will ever have about your own production. Label it with the scent, the bottle's date, the load in grams, the wax and the pour date, and keep the lids on in a closed carton out of sunlight — ordinary good practice rather than a published storage specification, since no oil page states one.Temperatures you can hold, and the three oils that change them
Add temperature is the second-largest controllable variable after cure, and unlike cure it is easy to drift on a busy day. The numbers are not yours to invent — they are printed on the wax page, and they differ by wax.
Stated working temperatures · CSI wax product pages, September 2026
Hold these, log these, and do not carry one wax's numbers over to another
| Wax | Stated fragrance step | Stated maximum load | From ₹ |
|---|---|---|---|
| Luxury Soy Wax Chunks | Add fragrance at 80–90°C; pour at 70–80°C | Up to 13% (8–13%, 10% recommended) | ₹299 / 500 g |
| Luxury Soy Wax CSI 464 flakes | Page states melt and pour at 80–90°C | Up to 10% | ₹260 / 500 g |
| Premium Coconut Soy CSI 468 | Melt at 50–53°C; pour at 58–60°C | Up to 13% | ₹325 / 500 g |
| Eco Soy CSI 400 | Add fragrance at 80–90°C (85°C), stir 2 minutes | Not stated on the page | ₹255 / 500 g |
Now the fragrance side of the same question. A flash point is the lowest temperature at which a liquid gives off enough vapour to form an ignitable mixture with air in the presence of an ignition source. It is a handling figure, and for a candle maker its practical use is as a sanity check on the temperature at which you add the oil. Only 18 of the 107 CSI fragrance-oil pages state a measured flash point; 32 carry only the perfume-grade threshold line "Flash point > 93°C (suitable for alcohol-based products)", which is a threshold for alcohol-based products and not a measurement of anything; and 56 state nothing at all. Where a page states none, ask for the SDS figure rather than borrowing a number from a similar scent.
Three of the eighteen measured values sit below 100°C, which is squarely inside the range where soy waxes are worked: Neroli states "Flashpoint: 85°C", Palo Santo states "Flashpoint: 93°C", and Gardenia states "Flashpoint 98°C" together with its own instruction — "add to wax below this temperature". Those three want the bottom of your wax's stated band rather than the top, and they want a thermometer in the wax rather than a guess. The rest of the measured values are comfortably above soy working temperatures: British Rose at 192°C, Verbena at 200°C, Vanilla Bean and Sandalwood at 203°C, Vetiver at 206°C. The mechanism and the fuller argument are in the guide to adding oil to hot wax.
The mistake: one add temperature for every oil in the range. A single number written on the wall is excellent discipline right up to the day a low-flash-point oil joins the range. Keep the wax's band as your default, then note per scent whether that oil's page gives you a reason to work at the lower end of it. Two columns on the recipe card — "add at" and "why" — takes ten seconds and stops an operator pouring a 98°C oil into wax at 90°C because that is what the wall says.

The CSI principle
A recipe is not what you did. It is what you wrote down while you were doing it. Everything else is a story about a candle you can no longer make.
The business that can reproduce a good candle wins on reorders. The business that produced a good candle once and cannot say how wins nothing, and spends the next season trying to find it again.
Consistency is boring, cheap and unglamorous, and it is the only thing standing between a hundred happy customers and a hundred slightly different candles.

Three pages that let you hold numbers constant
Chosen for what they publish, not for how they smell. Each one gives a production maker a figure to write on the card — a load, a cure, a flash point, a vanillin content — and each one has a gap worth naming.
1
The most complete process card in the range
Verbena Fragrance Oil
If you want a scent whose page fills in most of a batch card by itself, this is it. It states "Recommended Fragrance Load: Up to 10% for soy wax", "Up to 6% for paraffin wax", "Cure Time: 48–72 hours for soy wax", "24–48 hours for paraffin wax", "Flashpoint: 200°C", "Vanillin Content: 0% (No discoloration risk)", wax compatibility across "soy, paraffin, coconut", and even a wick line: "Cotton, Eco wicks or wooden wicks for steady, even burn. Test wick size based on con[tainer]". The profile is stated as a "crisp, clean, and citrus-forward single-note scent" with "sharp lemony zest with subtle herbaceous undertones". Zero vanillin and a 200°C flash point remove two variables outright — no tonal drift in white wax, and no anxiety about add temperature anywhere inside a soy band. The page never mentions IFRA, so request that documentation rather than assuming either way.

The page that tells you to change your add temperature
Gardenia Fragrance Oil
Included because it does the rarest thing a listing can do: it publishes a figure and then tells you what to do about it. It states "Flashpoint 98°C - add to wax below this temperature", which is a genuine instruction to set your add temperature at the lower end of your wax's stated band and to keep a thermometer in the wax. It also states "Vanillin content 0.2%" — low, but not zero, so worth a white-wax check rather than an assumption — a load of "Up to 10% for soy wax candles with a cure time of 48-72 hours" and "Up to 6% for paraffin wax", and a profile of "Rich, creamy, and velvety gardenia - true-to-life bloom character", described as "Softer and creamier than jasmine, more velvety than rose". Its specification block carries an IFRA row reading "Yes", which is an assertion rather than a document — ask for the paperwork by name and size. Customer Sraddha: "I found the ingredients to be of good quality."

Wide working margins, zero vanillin
British Rose Fragrance Oil
A single-note floral with the two properties that make a scent easy to keep consistent: "Flashpoint 192°C" — which its own page describes as giving "comfortable working temperature margins" — and "Vanillin content 0% - no discolouration or yellowing in wax", so white, cream and pastel waxes stay as poured. Load is stated as "Up to 10% for soy wax candles with a cure time of 48-72 hours" and "Up to 6% for paraffin wax", with wax melts up to 12%, reed diffusers 10–30% and room sprays quoted separately, so one bottle can serve several formats on documented rates. The profile is stated as "Fresh, dewy roses with subtle green and soft floral undertones", "Sophisticated, timeless, elegant - not heavy or synthetic". It is one of the 36 pages that never mentions IFRA. Customer Arshad Shaikh: "Fragrance oil is sooo good smell so good we love it a lot".

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles, which makes this page an awkward one to write honestly — because the most common consistency complaint a supplier hears is "your oil has changed", and the truthful answer is that nine more likely causes sit on the maker's side of the bench. This guide puts those nine first. It also states the gap on our side plainly: no CSI fragrance-oil page publishes a batch number, a lot number or batch-to-batch test data, so you cannot order "the same lot" and we will not pretend otherwise. What we can do is supply documentation on request and look at a specific, well-recorded report.
Every price, stated load, cure time, flash point and vanillin figure quoted here is taken from live CSI product pages in September 2026 and links to the page, where current specification always takes precedence. Flash points are only quoted for the 18 pages that publish a measured value; the threshold line "Flash point > 93°C (suitable for alcohol-based products)" on 32 other pages is not a measurement and is not treated as one, and 56 pages state nothing. No shelf life or storage specification is asserted anywhere, because 0 of 107 pages state one — storage advice here is ordinary good practice. Wax load ceilings and working temperatures are the wax pages' own figures and are formulation guidance, not regulatory limits.

Frequently asked questions
Why do my candle batches smell different from each other?
Usually because something on your bench moved, not because the oil did. In order of likelihood: the dose was not weighed, the cure lengths differed, the add temperature drifted, a new bottle went into production unchecked, or the wax, wick or vessel changed without being logged. Nine controllable causes sit above the oil itself. Fix the dose and the cure first — they are free — and only then compare bottles, using a retained jar and same-age candles.
How accurate does the fragrance dose need to be?
Within about ±0.5 g on a 16 g dose for a 200 g candle. Two grams out moves the load by nearly a full percentage point — 14 g gives 7.07% and 18 g gives 8.91% with the wax held at 184 g — and a systematic 2 g overdose is 2 kg of extra oil per 1,000 candles. Always weigh: no CSI page publishes a specific gravity, so there is no reliable millilitre-to-gram conversion for any oil in the range.
Should I test every new bottle of the same fragrance?
Yes, with one jar — not three. Pour it at your standard recipe with the dose weighed, cure it beside a jar retained from the previous bottle, and compare at day 14: cold throw first with the labels hidden, then a two-hour burn. This matters because no CSI page publishes a lot number, so a retained jar is the only reference you can actually hold. Record the verdict and keep a jar from the new bottle as the next reference.
At what temperature should I add fragrance oil?
At the band your wax page states. Luxury Soy Wax Chunks states adding at 80–90°C and pouring at 70–80°C; Eco Soy CSI 400 states adding at 80–90°C (85°C) with a 2-minute stir; CSI 468 states melting at 50–53°C and pouring at 58–60°C; the CSI 464 page states melt and pour at 80–90°C. Then check the oil: three pages publish a flash point under 100°C — Neroli 85°C, Palo Santo 93°C, Gardenia 98°C, the last with its own instruction to add below that figure.
What should be on a candle batch record?
Ten fields: date and batch number; scent, size and the bottle's date-in; wax and pack; grams of oil and grams of wax per candle; load and which basis it is calculated on; add temperature and stir time; pour temperature; vessel diameter and wick; cure start and assessment date; and the verdict plus who poured it. Write it at the bench, in grams, while it happens. Ninety seconds per batch, one folder per scent, and it answers almost any question a customer or stockist can ask months later.
How long should fragrance oil be stored, and does it change over time?
We cannot tell you, and neither can any product page: 0 of 107 CSI fragrance-oil pages state a shelf life, an expiry date, a storage temperature or a storage instruction. So treat storage as ordinary good practice — lids closed, out of direct sunlight, dated as bottles arrive — rather than as a published specification, and ask for the SDS if you need handling information in writing. For consistency purposes, what matters is not a claimed shelf life but that you can compare any bottle against a retained jar.

About this guide: Written by the CANDLEMAKINGSUPPLIESINDIA team. The protocols described — weighed dosing, one variable per batch, bottle qualification against a retained jar, the ten-field batch card — are standard production practice and apply to any supplier's oil. They are test methods, not results: nothing here reports the outcome of any test CSI has run, and no claim is made about how any specific oil performs in your wax. Quoted loads, cure times, flash points, vanillin figures and notes are verbatim from the linked product pages.Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on their product pages. Names, star ratings, dates and products are as recorded by Judge.me; one longer review is shortened with an ellipsis and otherwise unedited.
Figures verified September 2026: Load is calculated as oil ÷ finished candle. With the wax held at 184 g, a 14 g dose gives a 198 g candle at 7.07%, 15 g gives 199 g at 7.54%, 16 g gives 200 g at 8.00%, 17 g gives 201 g at 8.46% and 18 g gives 202 g at 8.91% — a 1 g change is about 0.46 percentage points. Oil per 1,000 candles is the dose × 1,000, so 14 g to 18 g spans 14 kg to 18 kg; costed at Verbena's listed 1 kg price of ₹4,720 (₹4.72 per gram) those are ₹66,080, ₹70,800, ₹75,520, ₹80,240 and ₹84,960, and a systematic 2 g overdose on 1,000 candles is 2 kg, ₹9,440. Per-candle oil cost = 1 kg price ÷ 1,000 × 16 g: Verbena ₹4,720 = ₹75.52; Gardenia ₹4,332 = ₹69.31; British Rose ₹3,068 = ₹49.09. Equipment: Candle Making Weighing Scale ₹354, Pen Thermometer ₹354, total ₹708; the scale page states it "shows measurements in grams or ounces" and states no resolution or capacity, and the thermometer page states no temperature range. Eco Candle Wicks from ₹59 for 10 in Thin (C1), ₹5.90 each. Wax pages: Luxury Soy Wax Chunks from ₹299/500 g, add fragrance 80–90°C, pour 70–80°C, up to 13% (8–13%, 10% recommended); Luxury Soy Wax CSI 464 from ₹260/500 g, page states melt and pour 80–90°C, up to 10%; Premium Coconut Soy CSI 468 from ₹325/500 g, melt 50–53°C, pour 58–60°C, up to 13%; Eco Soy CSI 400 from ₹255/500 g, add fragrance 80–90°C (85°C), stir 2 minutes, no maximum load stated. Fragrance-page coverage across all 107 CSI fragrance-oil pages: 18 state a measured flash point, 32 state only the threshold "Flash point > 93°C (suitable for alcohol-based products)", 56 state none; the three measured values below 100°C are Neroli "Flashpoint: 85°C", Palo Santo "Flashpoint: 93°C" and Gardenia "Flashpoint 98°C - add to wax below this temperature"; other measured values quoted are British Rose 192°C, Verbena 200°C, Vanilla Bean 203°C, Sandalwood 203°C and Vetiver 206°C. 36 pages never mention IFRA; none publishes a certificate number, amendment, category number, assessment date or downloadable document; 62 publish a vanillin or discolouration statement; and 0 state a shelf life, expiry date, storage temperature, storage instruction, batch number, lot number or specific gravity. Cure of 14–21 days reflects standard practice for soy container candles; the "48–72 hours for soy wax" figures are the minimum cure times stated on the oil pages quoted.
