CSI Diagnostics · New Oil Order Smells Different
A new order that smells slightly different is a question about two bottles, and your old open one may be the one that changed. Price what the oil will go into, then check in proportion: a strip, one candle or a full retest.
3 tiers
strip only → one candle → full retest, scaled to the rupees at stake · CSI live pricing, September 2026
Quick answers — read this first
My new oil order smells slightly different. Do I need new test candles? It depends on what the oil is going into. Scale the check to the rupees at stake: a strip check can be enough for a small run, one test candle suits a normal month, and a full retest belongs to a big or contracted order the moment the strip shows any difference.
Could my old sample be the one that changed? Yes, and it is easy to forget. An opened, half-empty bottle kept for months in a warm room can smell different from a fresh one (a tendency, strongest in bright citrus tops). Compare against a retained candle as well as the old bottle.
What are the three tiers? Tier 1: a blind strip check against your retained sample, two noses. Tier 2: one new-order candle burned against one retained candle at matched age. Tier 3: four new-order candles against two retained: the tier 2 side-by-side in duplicate, plus a full burn-down and the checks you ran when you first approved the scent.
What do they cost? In the worked example, tier 2 uses ₹532.59 of materials and tier 3 ₹1,597.78, excluding labour, freight, packaging and GST. Tier 3 is 30.0% of a 20-candle run, but 1.5% of a 400-candle Diwali order.
The short answer
The rule: the size of the check follows the size of the risk. Put a rupee figure on the run before you choose the tier.
The tiers: strip only (a few drops) → one candle (₹532.59) → full retest (₹1,597.78), worked example at 8% in 150 g jars.
The caution: your retained old sample may itself have aged. Compare the new order with a retained candle and, if you kept one, a full sealed vial, not only with the old open bottle.
The limit: CSI publishes no lot, batch, composition or reformulation data; ask on WhatsApp for the lot numbers on both orders. Nothing here implies a CSI batch changed.
Rupees at stake against the cost of each tier, drawn to scale for a worked example at 8% in 150 g jars. The tier costs are fixed; the runs they protect are not. That is why the same slight difference on a strip can justify a single candle for one run and a full retest for another. Tier choices are our judgement, not a rule.
My fragrance oil smells slightly different from my previous order. Should I make new test candles before using it in commercial production?
Make as many as the run is worth, and first make sure the difference is in the new order and not in your reference. An opened bottle kept for months can drift, especially in bright top notes, so compare the new oil with a retained candle and, if you kept one, a full sealed vial, as well as with the old bottle. Then put a rupee figure on what the new oil will go into and pick the tier. Tier 1, a blind strip check with two noses, is enough for a small run when nobody can pick the new oil out. Tier 2, one new-order candle burned against one retained candle at matched age, suits a normal month's production, or a small run where the strip did split. Tier 3, four new-order candles against two retained, including a full burn-down, is for a large or contracted order where the strip shows any difference, or a normal run where it shows a clear one. CSI publishes no lot or composition data; ask us on WhatsApp for the lot numbers on both orders.
One line: check your reference hasn't aged, price the run, then choose strip, one candle or a full retest in proportion.
Tier 2 needs one candle's materials: ₹266.30 in the worked example (12 g of the new order, 138 g of CSI 464, one 150 g jar and a C1 wick), set against a retained candle you already have. If you hold the wax, jar and wick, the new cash is nothing.
Which one changed: the new order, or your reference?
"The new bottle smells different from the old one" is a sentence with two bottles in it. Either can have moved.
The natural comparison is the new bottle against the one you have been using. But the old bottle is not what it was when it arrived: it has been opened, it may be half empty with air above the oil, it may have lived near a window or in a warm storeroom through the summer. Oils can change with age, air and heat (a tendency, and it tends to show first in the lightest, brightest notes). Tangerine's own page says of wear on skin that "Citrus notes fade faster"; a bottle of a bright citrus top that has been open for months is the classic case where the reference, not the delivery, has drifted.
So collect three witnesses before you decide the new order is different. The old bottle, with a note of when it was opened, how full it is and where it was kept. A retained sealed sample, if you kept one: a small glass vial filled to the top from the old order on arrival, stored cool and dark. A retained candle from a batch made with the old order, because the candle is what your customers buy. If the new oil smells like the sealed sample and unlike the open bottle, your reference aged. Your own stock is then the thing to audit (the hub's suspect order puts it second, and the own-stock audit runs it).
From this order on: a retained sample that stays honest
When a new order arrives, fill a small glass vial to the brim before you first open the bottle for production, label it with the order number, the lot number we give you on WhatsApp and the date, and keep it cool and dark. Keep two candles from the first batch made with it. That gives the next comparison a reference that hasn't been sitting open.
CSI publishes no lot, batch or composition data and no reformulation notices, and nothing on this page implies that a CSI batch changed. What we can do is give you the lot numbers on both orders when you ask on WhatsApp, so that whatever you find is written against real lots. The method for comparing an incoming batch in detail (strip, colour in wax, a test candle, what to record) is the new-batch comparison post; this page is about how far to take it.
Put a rupee figure on the run
A slight difference in twenty candles is a note in your log. The same difference in four hundred is a customer-service problem.
Before choosing a tier, work out what the new oil is about to go into. The worked example is Lavender Cranberry Coconut at 8% of total weight in 150 g candles (12 g of oil and 138 g of wax each), poured in CSI 464 into the 150 g Clear Glass Jar on a C1 wick. One candle carries ₹266.30 of materials at the 500 g oil price, excluding labour, freight, packaging and GST.

Material value is the floor, not the whole risk. A contracted order also carries your reputation, a delivery date and sometimes a sample the client already approved, and a returned corporate order costs far more than its wax. That is why the tier table below treats "contracted" as large whatever the candle count. If your oil is dearer, the stakes rise with it: a Tangerine candle carries ₹314.30 of materials, and a 100-candle Tangerine run ₹31,429.72.
Mistake: using the same check for everything, either always a full retest (and never getting product out) or never more than a sniff (and finding out from customers). What it does: the first wastes a third of a small run on testing; the second bets a large order on a strip. Fix: price the run first, every time, and let the price choose the tier.
Three tiers of gate, strip to full retest
Each tier answers a bigger question than the one before it, and costs more to ask.
Tier 1 · the blind strip check
Dip three scent strips equally: two from one oil and one from the other, coded underneath so the smeller can't tell which is which. Ask a second person to pick the odd one out, at one minute and again at thirty minutes, and repeat the set three times, swapping which oil is doubled. If they can't reliably pick the odd strip, the difference is below what a nose notices on a strip. If they pick it every time, it is real to the nose, which is not yet the same as real in a candle. Cost: a few drops of each oil. Strips show the oil neat; they cannot show how it throws from wax, which is why tier 1 alone is only for small runs.
Tier 2 · one candle against a retained candle
Pour one candle from the new order at your production load, in your production wax, jar and wick. Cure it to the age at which you normally judge, then burn it against a retained candle made with the old order, on separate evenings in the same closed room, with the same burn length and a blind 0–3 score (0 nothing, 3 fills the room). The retained candle is older, at least as cured as the new one. Cost: ₹532.59 of material value, of which only ₹266.30 is new.
Tier 3 · the full retest
Four new-order candles against two retained. Two new candles take the same side-by-side as tier 2, as duplicates; two more go through the checks you ran when you first approved the scent: a full burn-down to about 1 cm of wax left on your production wick (watching pool, flame, soot and carbon), a surface check for sweating at a week, and a colour check against the retained candle. Cost: ₹1,597.78 of material value, ₹1,065.19 of it new, and 48 g of the new oil, which a 50 g bottle covers with 2 g left. If the new oil burns differently (a taller flame, more soot), the wick question is the mini re-bracket post's; if it discolours differently, the colour-change post's.
Load basis and ceilings stay where they were
Every tier uses your approved load on total weight: 8% of a 150 g candle is 12 g of oil. This is a gate, not a reformulation, so do not use it to try a new load. If a later retest moves the load, keep it inside the lower of the oil page's and the wax page's stated maximum: Lavender Cranberry Coconut states 8–10% in soy and CSI 464 up to 10%, so 10% governs; Tangerine states no candle load in the text we captured, so the wax's 10% governs, and 9% of total weight is the cautious top rung that satisfies either reading of the ceiling.
Choosing the tier: difference against rupees at stake
Two questions pick the tier: how different did it smell blind, and how much is riding on it.
The table is our judgement of proportion, not a rule; move a cell up a tier if the scent is your bestseller or the client has a sample to compare with. "Small", "normal" and "large" follow the worked example: roughly up to one bottle's worth, a month's production, and anything contracted or seasonal.

If the new order and your old one are genuinely different products to you, and you are considering keeping the load and wick unchanged anyway, the risk of skipping each retest is set out in same smell, different composition. For the order you are about to place, rather than the one you have, see tests before ordering 5 kg.
The one-candle check, done properly
One candle is enough only if everything except the oil lot is the same as the candle it's compared with.
1
Pick the retained candleFrom a batch made with the old order, unburned, and note its pour date. If you kept none, make one now from the old bottle as a reference, knowing that bottle may have aged; say so in your log.
2
Weigh the new candle exactly as production12 g of the new order and 138 g of wax for a 150 g candle at 8% of total weight, on the same scale, from the same wax bag if possible, with the same wick and jar.
3
Match the processSame add and pour temperatures as your batch sheet, read on the same thermometer; in CSI 464 and the 150 g jar, pour at 80–85°C. Same stir time. Log the room.
4
Cure to your judging ageLavender Cranberry Coconut's page states no cure time in the text we captured; many makers judge soy at day 7 and 14 as common practice. Judge the new candle at the age you judged the old scent's approval candle.
5
Burn them apart, score them blindSeparate evenings, same closed room, same burn length, sniffed on entering by someone who doesn't know which candle is lit. Log pool, flame and any soot as well as the 0–3 score.
6
Decide and recordRead the decision table above, write the result against both lot numbers, and keep two candles from the first production batch as the next retained pair.
Mistake: pouring the new-order candle today and burning it tomorrow against a retained candle that is two months old. What it does: the comparison is between cure ages, not oil lots; a day-old soy candle commonly throws less than a cured one. Fix: wait for the new candle to reach the age at which you judged the old one, then compare. In our judgement, Diwali pressure makes this an easy step to skip.
What not to buy, or throw away
A slightly different bottle is a question, not a write-off, and not a reason to buy three more.
What not to do yet:bin the new order because the strip smelt different; the retained candle may say it performs the same. Order a 1 kg "backup" of the old lot: you can't choose a lot by ordering, and the 1 kg of Lavender Cranberry Coconut costs ₹1.00 more than two 500 g bottles anyway. Mix old and new bottles "to average it out": the batch then belongs to neither lot and can't be traced. Raise the load to make a weaker-seeming new order match: that is a reformulation, needs its own ladder, and must stay inside 10% here.
We sell both oils on this page, and for most gates the right purchase is nothing: tier 1 costs a few drops, and tier 2 uses one candle's materials that most makers already hold.
The oils and materials in the worked example
Four items: the worked example's bestseller, a perfume-grade citrus where an aged reference misleads most, and the wax and jar held constant in every tier. Chosen on page statements, price per gram and stock on 26 September 2026; CSI has no measured throw data, so nothing is ranked on throw. Oil tables list every size.
1
fragrance oil · fruity floral · the worked example's bestseller
Lavender Cranberry Coconut Fragrance Oil
The page states "Recommended load - candles: 8-10% soy wax" and describes "cranberry and sweet orange top notes, a French lavender and soft florals heart, and a coconut milk, vanilla, and white musk base". It also quotes an EDP usage ("Best as an EDP at 18-22%"), which is a perfume rate, not a candle load. It states no cure time in the text we captured. Every size is in stock on 26 September 2026. With CSI 464 (up to 10%) the governing maximum is 10%; a cautious top rung is 9% (13.5 g per 150 g candle). Argued against our own interest: the big sizes are not cheaper per gram here: 50 g is ₹7.98 a gram and 1 kg ₹8.00, and the 1 kg costs ₹1.00 more than two 500 g bottles. Do not stock up on a new order until it has passed the gate.
fragrance oil · citrus, perfume-grade · where a gate matters most
Tangerine
Tangerine is listed with CSI's fine perfume fragrances. Its page gives "Tangerine Peel, Mandarin, Bergamot" top notes, says it is "Best worn as EDT or fresh EDP (15–20%)" (a perfume rate, not a candle load) and notes, about skin, that "Citrus notes fade faster". The page does not state a candle load in the text we captured, so work inside the wax ceiling (CSI 464: up to 10%) and test your own load. Two reasons it belongs on this page: a bright citrus top is exactly what tends to smell different between a fresh bottle and one that has been open for months (a tendency), and at ₹12.00 a gram, 12 g of oil costs ₹143.98, ₹48.00 more per candle than Lavender Cranberry Coconut. Argued against our own interest: above 50 g, larger sizes save nothing per gram (the 1 kg costs ₹1.00 more than two 500 g bottles), and CSI's candle-grade citrus oils cost far less per gram (Citrus Lemon's 100 g is ₹3.00 a gram and states a candle load of 6–10%); ask us which suits your range on WhatsApp.
Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles
Tier 2 and tier 3 pour the new order in your production wax, from the same bag as the retained candles if you still have it. The page states "Fragrance Load Up to 10%" and "Pour Temperature 80°C – 90°C"; in the 150 g jar, pour at 80–85°C because the jar page's 85°C is the lower limit. If the 10% is read on wax weight it is 9.09% of total weight, so 9% of total is the top rung that satisfies both readings. Priced flat per gram from 1 kg to 10 kg.
The page lists "Height 8cm, outer diameter 7cm" and "Safe for hot pour up to 85°C". Use the jar your production uses; this one is the worked example's. Clear glass also shows you the new oil's colour in wax, which is the colour-change post's question, not this one. Argued against our own interest: if you have spare production jars, use those; the gate needs the same vessel, not a new one.
Diwali is 8 November 2026, 43 days from 26 September 2026. A tier 3 gate on a new order needs a cured candle and a full burn-down, so start it now if the order is for the season. Send us your run size and strip result, and we will quote oil, wax, wicks and jars with a GST invoice and dispatch date.
A strip for a small run, a candle for a month's production, a full retest when a contract meets any doubt, and always a question first about whether your reference has aged.
"The bottle you have been using for three months is not the bottle that arrived. Compare the new order with something that hasn't been sitting open."

Why trust this guide
CandleMakingSuppliesIndia sells the oils, wax and jars named here, and does not sell finished candles. This page still tells you that your own old bottle may be what changed, that above 50 g the larger sizes of both oils are no cheaper per gram, that Tangerine is dear for candles, and that the right purchase for most gates is nothing.
Every price and per-gram figure was verified on CSI's live store on 26 September 2026; every size in the pick tables is in stock on that date, and the tables are built to flag any that is not. Load, usage and note wording is quoted from the product pages; where a page is silent in the text we captured, we say so. CSI publishes no lot or batch data, composition or reformulation notices, and nothing here implies that a CSI batch changed.
The tiers, the tier chooser, the triangle strip method and the decision rules are editorial judgement; the runs and their rupee values are worked examples.

Frequently asked questions
Why does my new fragrance oil order smell different from the last one?
Either the new order differs or your reference has changed. An opened, half-empty bottle kept warm for months can drift, especially in bright top notes. Compare the new oil with a retained candle and a sealed sample as well as the old bottle.
Do I need to retest candles every time I reorder fragrance oil?
Not always to the same depth. Scale it: a blind strip check can do for a small run, one candle against a retained candle suits a normal month, and a full retest is for a large or contracted order with any strip difference, or a normal run with a clear one.
How do I compare two batches of fragrance oil on strips?
Use three coded strips, two of one oil and one of the other, and ask someone to pick the odd one out, at one minute and thirty minutes, three times over. If they can't pick it reliably, the difference is below what a nose notices on a strip.
How long should a test candle cure before comparing oil batches?
To the same age at which you judged the candle you're comparing it with. Oil pages that state a cure say 48–72 hours for soy; many makers judge at day 7 and 14. Comparing a day-old candle with a cured one compares cure, not oil.
Can I mix an old and a new bottle of the same fragrance oil?
You can, but in our judgement you shouldn't for a bestseller until the new order has passed its gate: a mixed batch belongs to neither lot and can't be traced if something goes wrong.
Does CSI notify customers when a fragrance oil changes?
CSI publishes no lot, batch, composition or reformulation notices. You can ask on WhatsApp for the lot numbers on your orders, and MSDS and IFRA documentation on request, and record them against your retained samples.

About this guide: part of CSI's cluster on a formula that suddenly gives a different result (3261–3280). This page owns a proportional go/no-go gate for a new oil order that smells slightly different: risk tiers (strip only, one candle, full retest) scaled to the rupees of production at stake, and the caution that the retained old sample may itself have aged. The incoming comparison method is 3191; colour change is 3266.
