Your vanilla candle probably changed twice, and only one of those changes is in the smell. Separate them before you reformulate.

Candle Business Guides · Storage & Stability
The lavender stock is dispatchable on this evidence; the vanilla stock is inspect-then-decide, and the first thing to inspect is whether what changed is the colour, the smell, or your expectation of the smell after seeing the colour. Yes, two oils can behave differently in storage — but no CSI page states a shelf life for either, so the ranking has to come from your own records.
2.5% vs not stated
vanillin content as published on the Vanilla Bean page against the Lavender page, which publishes none · the only stability-adjacent number in the range, and it predicts colour, not smell · CSI live pricing, September 2026
Quick answers — read this first
Can two fragrance oils really age differently in the same wax? They can, and makers report it constantly. But no CSI fragrance-oil page states a shelf life, an expiry or a storage instruction — 0 out of 107 — so there is no published ranking to appeal to. What is published, on 62 of those pages, is a vanillin and discolouration position. That is a colour statement, not a scent statement.Has my vanilla candle's fragrance changed, or its colour? Ask that first, because the two get reported as one. The Dark Vanilla page states plainly: "Yes. Dark Vanilla contains vanillin — a compound in vanilla and amber base notes that causes yellowing or browning in white and light-coloured wax over time." A candle that has gone cream-to-caramel looks different, and a candle that looks different smells different to a nose that has already seen it.
Why does the lavender seem untouched? Possibly because it is. Possibly because there was never a visible cue to prime you. The Lavender page states no vanillin figure and no discolouration position at all, so a lavender candle in white wax gives you nothing to see — and an unchanged appearance is not the same as an unchanged fragrance.
What do I actually do? Run a two-axis record: a colour log judged against a white sheet, and a blind scent comparison judged with the jars hidden. Twelve retained units across the two families costs ₹3,121.97 — 4.0% of a ₹78,049.20 mixed batch.
The short answer
Split the observation in two: colour is measurable against a white sheet and is genuinely addressed by the product pages. Scent is a perception and has to be judged blind, because seeing a browned candle changes what you smell.
Use vanillin for what it predicts: 2.5% on Vanilla Bean and on Cinnamon Vanilla, "Present" on Dark Vanilla, nothing stated on Lavender. Those figures forecast yellowing in light wax. They forecast nothing about throw.
Then reformulate the appearance, not the fragrance: a warm-toned wax, a dyed candle, an amber or coloured jar and an honest product description solve a vanillin colour shift without touching a load that is already inside the stated band.

Read the bottom row first. The field you want — how this oil behaves after six months on a shelf — is the one field no page fills in. The row above it is filled on three of four, and it is about colour. That asymmetry is the whole reason a vanilla candle "changes noticeably" while a lavender candle appears not to: one family hands you visible evidence, the other hands you none.

Straight answer
My lavender candle still smells fine after six months but my vanilla candle has changed noticeably. Can different fragrance oils have different storage stability?
Yes, different oils can behave differently over months — that is a fair reading of what makers observe. What cannot be honestly claimed is a ranking, because not one of CSI's 107 fragrance-oil pages states a shelf life, an expiry, a storage temperature or a storage instruction. So start with the part that is documented. 62 pages publish a vanillin or discolouration position, and on the vanilla family it is explicit: Dark Vanilla states "Vanillin Content Present" and answers its own discolouration question with "Yes… causes yellowing or browning in white and light-coloured wax over time"; Vanilla Bean states "Vanillin Content: 2.5% (Potential discoloration…)"; Cinnamon Vanilla states "Vanillin content 2.5% — moderate discoloration risk in light wax". The Lavender page states no vanillin figure, no discolouration position, no cure and no flash point — it states a base of "Soft musk — warm, rounded, longevity on skin and in wax", a strength of "Strong" and a load of 6–10%. So the vanilla candle almost certainly did change visibly, exactly as published, and a candle that has visibly darkened smells different to a nose that has already seen it. Separate the two axes before you touch the formula: log colour against a white sheet, judge scent blind against a cool-stored control. Twelve retained units across both families cost ₹3,121.97, or 4.0% of a 300-candle mixed batch worth ₹78,049.20.
One line: vanilla publishes a colour warning and lavender publishes nothing, neither publishes a shelf life — so log the colour, hide the jars, and judge the smell blind.
Building the paired record? Lavender 100 g ₹540, Dark Vanilla 100 g ₹790, Cinnamon Vanilla 100 g ₹483.80, Luxury Soy Wax Chunks ₹599 / kg and lidded 150 gram jars at ₹94.40 each — one wax, one jar, one wick, two families.

A vanilla candle that "has changed" has usually changed twice
You cannot smell a candle you have already looked at. Not fairly.
Here is the sequence that produces almost every "my vanilla has changed" report. Month one: a cream candle with a rich sweet top. Month six: the wax has gone from cream toward butterscotch or light brown, and the candle smells — to you, holding it — thinner, or stranger, or somehow older. Two observations, one conclusion, and the conclusion skips a step. The colour shift is documented on the product page. The scent shift is not documented anywhere, and it was assessed by a person who had just seen the colour shift.
This is not a criticism of your nose. It is how judging works. Expectation is part of perception, and a visible change is the strongest possible cue for an expectation. That is precisely why the instrument in this post is two separate records that cannot contaminate each other: a colour log, which is objective and can be photographed, and a blind scent comparison, in which the assessor cannot see the candle at all.
The mistake: reformulating the fragrance to fix a colour problem. If the real change is vanillin-driven yellowing — which the Dark Vanilla page tells you to expect in white and light wax — then switching oils, raising the load or shortening the cure addresses nothing and costs money on every candle. The fixes for a colour shift are appearance fixes: pour the range in a warm cream or amber tone from the start with a liquid dye, use a coloured or amber vessel, keep cartons out of daylight, and describe the candle honestly at the point of sale. Why some vanilla fragrance oils turn candle wax yellow has the mechanism.
"Vanilla" in the name is not the test
Vanillin is declared on the page, not in the product title. Of CSI's 107 fragrance-oil pages, 62 publish a vanillin or discolouration position, 18 give a numeric vanillin content and 6 state it as "Present" — and several oils with no vanilla in the name carry a discolouration note anyway, because amber, tonka, caramel, tobacco and coffee materials can bring vanillin with them. Read the page, not the name. The reverse also holds: Vanilla Orange Blossom states that it "will cause browning in white or light-coloured wax and soap bases over time", while Zesty Lemon states 0% vanillin and zero discoloration risk.What the two pages publish, field by field
Every entry below is the product page's own wording. The value of this table is not the filled cells — it is where the asymmetry sits, and what both columns have in common at the bottom.
Lavender against three vanilla oils · stated fields only · CSI live pricing, September 2026
Notes, strength, load, cure, flash point, vanillin — and shelf life
| Field | Lavender | Dark Vanilla | Vanilla Bean | Cinnamon Vanilla |
|---|---|---|---|---|
| Base as stated | "Soft musk — warm, rounded, longevity on skin and in wax" | "Dark amber, warm musk — deep, grounding, long-lasting" | Single note; "Main Aroma: Creamy, sweet vanilla with subtle caramel undertones" | "Cream, butter — indulgent, lingering, comforting warmth" |
| Stated strength | "Strong" | "Strong — impactful at lower loads" | "Moderate to strong, providing a warm and inviting throw" | Gourmand / Spice / Warm; "warm, cosy, and indulgently sweet" |
| Stated candle load | 6–10% for candles | 6–10% for candles | Up to 10% for soy, up to 6% for paraffin | Up to 13% load for candles |
| Stated cure | Not stated | "At least 48–72 hours" for soy | 48–72 hours soy, 24–48 paraffin | Stated on page |
| Stated flash point | Not stated | ~191–193°C | 203°C | 270°F (132°C) |
| Vanillin / discolouration | Not stated at all | "Vanillin Content Present… will yellow white wax over time" | "2.5% (Potential discoloration; test with lighter waxes…)" | "2.5% — moderate discoloration risk in light wax" |
| Stated shelf life or storage | None | None | None | None |
| 100 g / 1 kg price | ₹540 / ₹5,221 | ₹790 / ₹7,646 | ₹790 / ₹7,646 | ₹483.80 / ₹4,554.80 |
Worked out above: oil cost inside one 150 g candle at an 8% load = 12 g × (1 kg price ÷ 1,000). Lavender ₹5.221/g = ₹62.65 · Dark Vanilla and Vanilla Bean ₹7.646/g = ₹91.75 · Cinnamon Vanilla ₹4.5548/g = ₹54.66. At the 100 g price the same 12 g is ₹64.80, ₹94.80 and ₹58.06. The "longevity on skin and in wax" phrase on the Lavender page describes how its musk base note persists; it is not a storage claim and CSI does not present it as one.
One more honest point about the Lavender column. It is the thinnest column in the table — no cure, no flash point, no vanillin figure — and yet lavender is the candle that came through six months apparently untouched. That should tell you how little the published fields have to do with the outcome you care about. A page with more fields filled in is a better-documented product, not a more stable one.
The differential: which of the four changes are you actually looking at?
Four candidates, and they lead to four different actions. Work down the table with the candle in front of you and a control beside it. If you have no control, the last column tells you what you can and cannot conclude — which for two of the four rows is "nothing yet".
The differential · vanilla candle changed, lavender candle unchanged, six months
Candidate, distinguishing observation, and the action it justifies
| Candidate | What points to it | The observation that separates it | Action it justifies |
|---|---|---|---|
| Colour changed; scent did not | Visible yellowing or browning in the vanilla only; the page states a vanillin position | Blind scent comparison against a cool-stored control cannot separate them | Appearance fix: tinted wax, coloured jar, honest description. No formula change |
| Colour changed and primed the nose | You scored the vanilla lower after looking at it; a blind assessor does not | Two blind rounds with the order reversed, jars hidden | Change the inspection protocol, not the product |
| Scent genuinely changed in the vanilla | Blind comparison separates aged from control repeatedly, at matched temperature, over several sessions | The retained control — the only route to this conclusion | Reconsider the oil, the holding time, or the storage conditions |
| Both candles changed; only one shows it | The lavender also separates from its own control once judged blind | A control for each family, not just the suspicious one | Shorten holding time across the range |
Do not keep a control for the family you suspect only. This is the quiet error that makes the whole exercise useless. If you hold back six vanilla candles and no lavender candles, you have built a test that can only ever find vanilla problems — and the fourth row above becomes invisible. Retain units from every family in the batch, in the same proportion, and judge them all at the same checkpoints. Six per family, three cool and three with the inventory, is a defensible split and a cheap one: on the figures below, twelve units across two families is ₹3,121.97.
The two-axis record, step by step
The instrument for this question is a single sheet with two independent halves. Checkpoint intervals, sample counts and scoring scales below are our method rather than a published standard — choose your own and then never change them mid-programme, because a protocol that drifts produces differences that belong to the protocol.
1
Pour both families in one session, from one wax lotSame wax, same jar, same wick, same load, same day, same add and pour temperatures. A 150 g candle at 8% is 138 g of wax and 12 g of oil. On Luxury Soy Wax Chunks the page states fragrance in at 80–90°C and a pour at 70–80°C — write down the readings you actually got, for both halves.
2
Retain six per family: three cool, three with the inventoryThe three cool units are the control. Lids on, in a closed carton, in the coolest dark interior space you have. The three inventory units sit on the real shelf in the real packaging. Label them on the base, not the lid — you will be hiding these jars later and a visible label defeats the blind round.
3
Axis one — the colour logAt each checkpoint, stand one control and one aged unit side by side on a plain white sheet in daylight away from direct sun, photograph them together in one frame, and score the aged unit 0 to 3 against the control: 0 identical, 1 faintly warmer, 2 clearly yellow, 3 brown. One frame with both jars is worth more than two separate photographs, because the sheet and the light are then identical.
4
Axis two — the blind scent roundHave someone wrap both jars or place them in identical bags, hand them to you in random order, and record your 1–5 cold-throw score for each without seeing them. Reverse the order and repeat. Both jars must have stood in the same room together for at least four hours first, which is this guide's chosen equilibration period, not a standard. If you can only do this alone, decant nothing — just cover the jars and have the room's other occupant shuffle them.
5
Checkpoints at day 14, week 6, week 12 and week 24Day 14 is the baseline, after the cure has done its work — the Luxury Soy Wax Chunks page asks for a minimum of 48 hours and ideally one to two weeks before burn testing, and 14 days is the standard practice this series uses. Record both axes at every checkpoint for both families. A row with a rising colour score and a flat blind score is the single most useful line you can own.
6
Burn one aged unit of each family at week 24Appearance and cold throw do not test the product a customer buys. Burn for up to three hours in a closed room: time to a full melt pool at the glass, flame behaviour, soot, hot throw at 30 and 120 minutes. A stored vanilla candle that is visibly darker but burns and throws normally is a description problem, not a quality problem. Use the sheet in how to test hot throw before launching a candle fragrance.
Photograph the control, not just the suspect
A photograph of a browned vanilla candle proves nothing on its own — phone cameras adjust white balance, and a cream candle in warm light looks yellow. Both jars in the same frame, on the same white sheet, in the same light. That single habit turns an argument with a customer or a stockist into a document, and it costs nothing. Keep the frames in one folder with the checkpoint date in the filename.Buying for a batch that has to sit for months

Floral · nothing stated about discolouration
Lavender Fragrance Oil
The family in your batch that gave you no trouble, and the one whose page publishes the least. It states a pyramid of fresh lavender, herbal green notes, and a base of "Soft musk — warm, rounded, longevity on skin and in wax"; strength "Strong"; a candle load of 6–10%, with 10–15% for wax melts and a note that "Lavender projects well at lower loads". It states no vanillin figure, no discolouration position, no cure and no flash point. At ₹540 per 100 g and ₹5,221 per kilo, 12 g in a 150 g candle is ₹62.65 at the kilo price. Read its thin spec sheet honestly: it is the least documented of the four oils here and it was still the one that came through — which is why your own record matters more than the page.

Gourmand · vanillin stated as Present
Dark Vanilla Fragrance Oil
The oil that tells you in advance what you observed. Its page states "Vanillin Content Present — Vanilla and amber base notes contain vanillin — will yellow white wax over time" and answers the discolouration question with "Yes", describing the result as expected and normal. It also states a base of "Dark amber, warm musk — deep, grounding, long-lasting", strength "Strong — impactful at lower loads", a load of 6–10% for candles, a soy cure of at least 48–72 hours and a flash point of ~191–193°C. At ₹790 per 100 g and ₹7,646 per kilo it is ₹91.75 of oil in a 150 g candle — ₹29.10 more per candle than lavender. Buy it knowing the colour will move, and design the candle around that.
| Size | Price | Per 100g | 150g candles @ 8% |

Gourmand · vanillin stated as a figure
Cinnamon Vanilla Fragrance Oil
The cheapest gourmand of the three and the one that quantifies the risk: its page states "Vanillin content 2.5% — moderate discoloration risk in light wax", a flash point of 270°F (132°C), a base of "Cream, butter — indulgent, lingering, comforting warmth" and a load of up to 13% for candles. At ₹483.80 per 100 g and ₹4,554.80 per kilo, 12 g costs ₹54.66 — less than lavender. A stated 2.5% and a stated "Present" are not comparable numbers, and neither predicts throw. Both tell you the same practical thing: do not build a bright white candle on them and then be surprised. Vanilla Bean states the same 2.5% with a 203°C flash point at ₹790 per 100 g.
| Size | Price | Per 100g | 150g candles @ 8% |
|---|---|---|---|
| 15 gm | ₹106.20 | ₹708 | ≈1 |

The arithmetic of a mixed-family batch
A 300-candle run split evenly between the two families, in 150 g lidded jars at an 8% load on Luxury Soy Wax Chunks at ₹599 a kilo, with a C1 wick from a 100-pack and a Clear Glass Jar with Golden Lid (150 gram) at ₹94.40 each. Every figure is listed price; the working is in the citation strip.

| Six retained units per family | ₹1,473.66 | ₹1,648.26 |
| Cost of the whole record | ₹3,121.97 — 4.0% of the batch | |
Two conclusions from those rows. The first is that the vanilla half is the more expensive half before anything ages — ₹29.10 more per candle, ₹4,365 more across 150 units — so it is also the half where a wrong decision costs more. The second is that the record which would have answered your question costs 4.0% of the batch, and it had to be bought on pouring day. It cannot be bought in month six. That is the honest, slightly uncomfortable core of this whole subject: the cheapest moment to build the evidence has already passed for the stock in your hand, and is about to pass again for the batch you pour next week.
The CSI principle
Vanillin is a colour forecast. Treat it as a scent forecast and you will reformulate the wrong half of the candle.
Sixty-two of our fragrance pages publish a discolouration position because discolouration is the part that is genuinely predictable. None publishes a shelf life, because that part has not been measured. Buying on the first and guessing at the second is how a good gourmand range gets abandoned for no reason.
Ready for production? Lavender 1 kg ₹5,221, Cinnamon Vanilla 1 kg ₹4,554.80, Dark Vanilla and Vanilla Bean 1 kg ₹7,646. One kilo is the largest listed fragrance pack — recurring and larger volumes are quoted on WhatsApp, with GST invoicing and documentation.

What the next formula changes — and what it leaves alone
The gourmand range does not need a new oil. It needs a candle that was designed to darken.
If your record shows a rising colour score and a flat blind scent score — the most common outcome — then the next batch changes its appearance strategy and nothing else. If the record shows a real blind difference, the levers are holding time and storage conditions first, and the oil last, because changing the oil restarts every other test you have run.
After the record
What a two-axis result justifies changing in the next batch
| Lever | When the record justifies it | What it costs |
|---|---|---|
| Tint the wax from the start | Colour score rises, blind score flat | A liquid dye; a few rupees per candle, and it removes the complaint entirely |
| Move the gourmands into coloured or amber glass | Colour score rises on white-wax lines in clear jars | Jar cost only — amber 120 gm jars are ₹47.20 each |
| Say it on the label and the listing | Any stated vanillin position on the oil | Nothing. "Natural deepening of colour over time" is accurate and pre-empts the question |
| Shorten how long gourmands sit before dispatch | Blind score separates repeatedly | Production scheduling; pour later, dispatch sooner |
| Change the oil | Only after the three levers above have failed across two batches | Restarts wick, cure and throw testing for that line |
| Raise the fragrance load | Never, as a response to a storage observation | Money on every candle, with no diagnosis attached |
And keep the controls beyond the programme. Three cool-stored jars per family, dated, are your reference for next year — and for the first stockist who asks how your candles hold up on a shelf. If you are planning a festive run, that question arrives early: Diwali 2026 falls on 8 November 2026, so anything poured now is a stored product by definition. How to plan fragrance inventory before the festive season covers the ordering side.

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. We sell both families discussed here, and the dearer one is the vanilla. It would be commercially convenient to tell you the vanilla changed and you need a different oil. Instead this page tells you the likely answer is a tinted wax and a better-worded label — and that the oil is probably fine.
Every price and pack size comes from live CSI stock in September 2026 and links to the product page, which is always authoritative. Stated notes, strengths, loads, cure times, flash points and vanillin positions are quoted verbatim from the product pages; nothing is inferred from them, and a stated maximum load is a wax-and-oil formulation limit, not a regulatory limit or a stability promise. Where a page states nothing, this guide says "not stated" rather than filling the gap — and on shelf life, expiry, storage temperature and storage instructions, all 107 fragrance-oil pages state nothing. No ageing rate, decay curve, percentage-loss figure or accelerated-to-real-time conversion appears on this page, because no such figure has been measured to publish.

Frequently asked questions
Does vanillin make a candle's fragrance fade faster?
Nothing CSI publishes says so. Vanillin is stated on the pages in connection with colour: "Vanillin Content Present… will yellow white wax over time" on Dark Vanilla, "2.5% (Potential discoloration…)" on Vanilla Bean, "2.5% — moderate discoloration risk in light wax" on Cinnamon Vanilla. Treat it as a colour forecast. Whether the scent also changed is a separate question that only a blind comparison against a cool-stored control can answer.
Which fragrance oils are most stable in storage?
There is no honest answer available from product pages, because none of CSI's 107 fragrance-oil pages states a shelf life, an expiry, a storage temperature or a storage instruction. Any list ranking oils by stability is somebody's guess. What you can do is generate your own ranking for the oils you actually use: retain six units per family from every batch, three cool and three with the inventory, and score them blind at day 14 and weeks 6, 12 and 24. After two batches you will have something no supplier can give you.
Can I still sell a vanilla candle that has turned yellow or brown?
That is your commercial decision, and the Dark Vanilla page describes the shift as expected and normal for vanillin-containing fragrances, which supports describing it rather than hiding it. Inspect before you dispatch: glass integrity, wick position and condition, surface, and a full test burn on at least one unit. Cracked glass, a wick touching the glass, a clogging wick or a jar that runs unsafely hot must not ship whatever the colour. Colour alone is a description and pricing question.
Is lavender genuinely a safer choice for candles I have to hold?
On published evidence, only in one respect: the Lavender page states no vanillin content and no discolouration position, so there is no stated reason to expect a visible colour shift in white wax. That is a real advantage for a white candle. It is not a statement about scent, and the same page states no cure time and no flash point — it is the least documented oil in this comparison. Test it against a control like everything else.
How do I tell whether the colour change affected the smell or just my judgement?
Hide the jars. Have someone wrap the control and the aged unit identically, hand them to you in random order, and score the cold throw of each without seeing them — then repeat with the order reversed. Both jars must have stood in the same room together beforehand; this guide uses four hours as its equilibration period, a chosen method rather than a standard. If you cannot separate them blind, the colour changed and your judgement followed it. That is the most common result by a wide margin.
What does it cost to keep retained samples on every batch?
On a 300-candle run of 150 g jars split between the two families, six retained units per family cost ₹1,473.66 for lavender and ₹1,648.26 for Dark Vanilla — ₹3,121.97 in total, or 4.0% of a ₹78,049.20 batch. Materials per candle are ₹245.61 and ₹274.71 respectively on listed prices. The units are not wasted: three per family come back as burn tests at week 24, and the cool-stored three become next year's reference.

Stated specifications as published on product pages: Lavender — base "Soft musk - warm, rounded, longevity on skin and in wax", strength "Strong", candle load 6–10%, wax melts 10–15%, "Lavender projects well at lower loads"; no vanillin, discolouration, cure or flash point stated. Dark Vanilla — "Vanillin Content Present", "Vanilla and amber base notes contain vanillin - will yellow white wax over time", discolouration answer "Yes… causes yellowing or browning in white and light-coloured wax over time", base "Dark amber, warm musk - deep, grounding, long-lasting", strength "Strong - impactful at lower loads", load 6–10% for candles, soy cure "at least 48-72 hours", flash point ~191–193°C.

Range-wide counts from the 107 saved fragrance-oil page texts: 62 pages publish a vanillin or discolouration position, 18 state a numeric vanillin content, 6 state it as "Present", and 0 state a shelf life, expiry, best-before date, storage temperature or storage instruction. Loads are formulation limits, not regulatory limits. Planning assumptions labelled in-text: fragrance load as a percentage of finished candle weight (150 g at 8% = 138 g wax + 12 g oil); a 14-day cure before the baseline; checkpoints at day 14 and weeks 6, 12 and 24; six retained units per family split three cool and three with the inventory; a four-hour equilibration before any cold-throw judgement; a 0–3 colour scale and a 1–5 throw scale — all of these are this guide's chosen method, not a published standard. No ageing rate, migration rate, percentage-loss figure, sweating temperature or accelerated-to-real-time conversion appears anywhere on this page, because no CSI product page states one, and no wax page states a storage instruction either. Diwali 2026 is 8 November 2026. Prices and availability change — the linked product pages are always authoritative.
