I Want to Buy Reed Diffuser Fragrance Oils Wholesale With Reliable Heat Stability — How Do I Compare Indian Suppliers Before Scaling Manufacturing?
Start from the position nobody in this trade states plainly: heat-stability data for reed diffuser fragrance oils is not published by any supplier whose pages you can read, and that includes CSI. No flash point used as a working temperature, no volatility, no evaporation rate, no storage temperature, no shelf life. So "compare suppliers on heat stability" cannot mean reading and ranking. It means a request letter you send to all of them identically, a sealed sample you retain from every delivery, and a bench of your own that fills the column nobody else will.
₹772.04
What it costs to stand one supplier up on your own bench — two matched 120 ml bottles, one in your hot room and one cool-stored, plus a sealed 12 ml retention. Their oil is extra; their data does not exist · CSI live pricing, October 2026
Quick answers — read this first
Which supplier publishes the best heat-stability figures? None of them, and that is the honest answer rather than a dodge. CSI publishes no temperature data of any kind for any oil, base, reed or bottle, and we have not found a reed-diffuser-oil page anywhere that publishes an auditable one either. A figure quoted to you verbally is a claim, not a specification.So what do I actually compare? Three things you can hold in your hand: what each supplier returned in writing, what you retained from each delivery, and what your own bench measured under their name. That is the supplier row, and it accumulates. After three deliveries it is worth more than any brochure.
What does the bench cost? ₹772.04 a supplier for the two matched bottles and the retention, excluding their oil. Three suppliers, resolved into whole packs and with the instruments, is ₹5,028 once — and the fourth and fifth suppliers after that cost ₹236 each, because the packs are already bought.
What should I ask for? Ten things, listed below, the same ten to every supplier. Documentation is available on request — a safety data sheet, IFRA documentation as issued, an allergen declaration — and it is never summarised, here or anywhere. You receive it, you file it intact, and you hand it to a qualified adviser.
The short answer
Request, retain, record: one identical letter to every supplier, one sealed 12 ml retention from every delivery at ₹36, and one weighed bottle per supplier on a fixed checkpoint calendar. Everything else is somebody's marketing.
Comparability is the whole game: two supplier rows are only comparable if the base, bottle, reed count, load, room and checkpoint dates were identical. Change any one of those and you have two observations rather than a comparison.
A bench run screens for change, it does not predict life: a short high-temperature run can show cloudiness, separation, colour movement or odour drift against a cool-stored control. It never converts into a days figure, at any ratio. That rule does not bend for a supplier decision.

The column everyone wants to shop on is the one nobody can fill. The four that remain are all yours — what came back in writing, whether a sealed retention exists, what the scale recorded, and how many blind judgements landed correctly against a cool-stored control. A supplier with an empty right-hand side has not failed; it has simply not entered the comparison.

Straight answer
How do I compare Indian fragrance oil suppliers on heat stability before I scale?
Not on their data, because there is none to compare. CSI publishes no temperature information of any kind — no flash point used as a working temperature, no viscosity, no volatility, no evaporation rate, no heat-stability statement, no storage temperature, no shelf life — and the same absence is the norm across this category rather than a quirk of one shop. So the comparison is built out of three things that are genuinely yours. One: the request letter. Ten lines, sent identically to every supplier, asking for documentation and batch identity rather than for performance promises. What comes back — and what does not — is your first column, and a supplier who will not answer ten plain questions has told you something useful before a single rupee moves. Two: the retention. A 12 ml sealed bottle at ₹36, drawn from every delivery, dated, kept cool and dark. Without it, a question about whether this month's oil matches last month's is unanswerable forever. Three: the bench. Per supplier, two matched 120 ml bottles — one in your own hot room, one cool-stored from the same filling session — identical in base, bottle, reed count and load, weighed cap-off on fixed dates on a ₹354 scale with the room temperature from a ₹354 pen thermometer written beside every weight. That pair of bottles plus the retention costs ₹772.04 excluding their oil, and it produces two numbers nobody can argue with: grams lost per day, and a count of correct blind same-or-different judgements against the control. Three suppliers, bought as whole packs with the instruments, is ₹5,028 once — and the fourth and fifth cost ₹236 each because the packs are already on the shelf. One rule that does not bend: a short high-temperature run screens for change and never predicts life. It cannot be converted into days, for any supplier, at any ratio.
One line: you are not comparing suppliers' heat-stability data — nobody has any — you are comparing what they sent you and what your own scale recorded under their name.
The whole comparison bench: Candle Making Weighing Scale ₹354, Pen Thermometer ₹354 (only 19 units listed), Silicon Measuring Beaker 100 ML ₹300 and Attar Bottles 12 ml ₹360 for ten. ₹1,368 of instruments that every supplier row afterwards reuses.

The data you are asking for is not published by anyone
You cannot shortlist on a column that is empty for every row. So fill the other columns.
It is worth being precise about what is missing, because the shape of the gap determines what replaces it. Four properties come up in every one of these conversations, and not one of them is published anywhere you can audit — not by CSI and not, as far as we have been able to find, by any reed-diffuser-oil page in this market. A number given to you in a message is a claim; a number on a page with no method behind it is also a claim.
Four properties buyers shortlist on · what exists and what stands in
The request, the bench reading, and what each entitles you to say
| Property | Published by CSI? | What to request in writing | The bench reading that stands in | What you may then state |
|---|---|---|---|---|
| Heat stability | No — no temperature data of any kind | Batch identity, date of manufacture, documentation as issued | Grams lost per day on a weighed bottle in a room whose temperature you recorded | What your bottles did, in your conditions, on stated dates |
| Volatility or evaporation rate | No | Nothing — do not ask for a figure nobody holds | A plain-base blank beside the scented bottle, both weighed on the same dates | How much of the weekly loss was carrier rather than fragrance |
| Odour consistency batch to batch | No — no batch code, no tolerance | A pre-shipment sample drawn from the lot being shipped | Coded blind same-or-different against your retained reference | How many judges identified the odd sample, out of how many tried |
| Shelf life | No | The storage condition the supplier themselves recommends | Dated retentions opened on a re-check interval you chose | How your retained samples looked and smelled on each dated opening |
| Viscosity and solubility | No | Nothing published; ask only for the documents | Clarity in your own base at your own load after the published 24–48 hour rest | Clear or not, in your base, at your load, on that date |
What CSI does publish, quotable as CSI's own words: every reed base page states "Blend with 10-30% fragrance oil", a 25–30% working ratio and a 24–48 hour rest before bottling. The fibre reed pages state 20.3 cm length, count bands of 4–5 / 6–8 / 10+, "flip every 3-5 days", "1-2 hours initial absorption", "does not swell in heat or humidity" and "avoid placing in direct sunlight or near heat sources which accelerate evaporation". Pure Performance states it "performs well in Indian climates by balancing scent throw with longevity" and that "heat and humidity create specific challenges". Those are the only heat and airflow remarks in the entire range and none of them is a rate, a multiplier or a per-degree figure. On commercial terms the range is equally sparse: no lead time, dispatch window, courier, credit term or minimum order quantity is published for any product here — the single published MOQ anywhere in the range is a 12 ml car bottle's "Minimum Order: 12 pcs" — so do not plan a supplier comparison around terms you have not been given in writing.
One consequence worth stating out loud: "our oils are heat stable" is not a comparable input, and neither is "alcohol-free" unless the supplier has put it in a document. On CSI's own shelf, alcohol-free is the default inference because no perfumer's alcohol is listed — but the Pure Performance page publishes no composition, no ingredient list and no alcohol-free statement, only "no added fixatives / no complex enhancements". If you need that claim on a label, it comes from requested documentation, not from a reasonable inference. The same discipline applies to every supplier you are weighing up.
The request letter: ten lines, sent identically
Send the same ten lines to every supplier, in the same order, in writing. Identical wording is what makes the replies comparable — and the pattern of what comes back is the first real data in the whole exercise.
Ten lines · one letter · every supplier
What each line asks, what a good answer unlocks, and what a refusal tells you
| # | The line | What a clear answer unlocks | What silence tells you |
|---|---|---|---|
| 1 | The exact product name and grade you are quoting | Everything else can be attached to something specific | Nothing below is enforceable — stop here |
| 2 | A safety data sheet for the material as supplied | Handling and storage decisions in your own unit | A basic document gap worth asking about twice |
| 3 | IFRA documentation, as issued, for our records | Your compliance adviser's file for the finished product | A conversation to have before scaling, not after |
| 4 | Allergen declaration for labelling purposes | Your labelling adviser's input | Labelling work you cannot complete |
| 5 | A batch or lot identifier marked on every container | Any later question about consistency becomes answerable | You will have to date and mark containers yourself |
| 6 | Date of manufacture for the lot being shipped | A real zero point for your own records | Use the delivery date and say so in your file |
| 7 | A pre-shipment sample drawn from this lot | You approve what is actually coming, not a predecessor | Any approval you give is approval of nothing |
| 8 | Notice before any change of composition, and what counts as one | You can shorten your re-test interval around real events | Retain from every single delivery, without exception |
| 9 | The storage condition you yourself recommend | Where the stock sits in your unit between runs | Choose a cool dark position and record it as your choice |
| 10 | One named person who signs lines 2 to 9 | Answers stop drifting between replies | Expect to re-ask everything on the next order |
The mistake: asking for performance instead of paperwork. "Can you confirm this oil is stable at 40 °C?" invites an answer that is either a guess or a sales line, and once it is in writing it feels like a specification. Nobody holds that figure, so nobody can give it to you honestly. Ask instead for the documents, the batch identity and a sample from the shipped lot — all of which are concrete, checkable and genuinely available — and keep the performance question for your own bench, where it belongs. And when the documents arrive, file them intact. Documentation in this category is available on request and is never summarised: not by us on a product page, not on this page, and not in your own internal note. A paraphrase of a safety document is a liability dressed as convenience. 10651 covers what to request about a base and 10654 the coded sample comparison.
What to keep from every delivery
The retention regime is the cheapest permanent advantage available to a small manufacturer, and almost nobody runs it. A sealed 12 ml bottle costs ₹36 and makes every future consistency question answerable. Without it, the honest answer to "did this batch change?" is "we have nothing to compare it with", for the rest of the product's life.
The retention regime · ₹36 a vessel · 12 ml each, packs of ten at ₹360
What to draw, when, and what it is the only fixed point for
| Retention | Drawn from | Drawn when | Opened against | Cost |
|---|---|---|---|---|
| Approval reference | The pre-shipment sample you approved | Before the order is placed | Every delivery that follows | ₹36 |
| Delivery reference | Neat oil, every delivered container | Goods-in, before production starts | The approval reference, and the next delivery | ₹36 each |
| Blend reference | Your finished blend, after the stated 24–48 h rest | At bottling | The same blend made from the next batch | ₹36 plus ₹19.78 of base |
| Cool-stored control bottle | The same filling session as your warm arm | Day 0 of every trial | The warm arm at every checkpoint | ₹368.02 a bottle |
| A year of three suppliers | Four deliveries each | Rolling | Each other, by date | 12 retentions · ₹720 |
Worked out above: Attar Bottles 12 ml are ₹360 for a pack of ten, so ₹36 each — the cheapest sealed vessel in the range. The live title reads "Attar Bottles ( 3ml, 6ml, 12 ml)" while the handle promises a 2 ml: there is no 2 ml variant, the three sizes are 3 ml ₹180, 6 ml ₹300 and 12 ml ₹360, all packs of ten. A blend reference at the published 25% ratio is 9 ml of base plus 3 g of oil, so the base alone is 9 × ₹2.198 = ₹19.78 and the oil is the supplier's, which this page cannot price. A cool-stored control bottle at 120 ml, 25% and eight black reeds is base ₹197.82 + glass ₹106.20 + reeds ₹64.00 = ₹368.02 excluding the oil. Twelve retentions is two packs of ten at ₹360 = ₹720.
Date the label, not just the batch
Write two dates on every retention: the date you drew it and the date you intend to open it next. The second one is the difference between a retention programme and a drawer full of unlabelled bottles. There is no published shelf life for anything in this range, so the re-check interval is entirely your choice — pick one, write it down, and treat it as a decision you made rather than a figure somebody gave you.Standing one supplier up on your own bench
Two bottles and one retention per supplier. Everything except the supplier's oil is held identical — that is the entire design, and it is what makes the rows comparable at the end.
1
Fix the six comparability lines in writing before any supplier's oil arrivesOne base — Pure Performance is the sensible default because its page speaks to Indian conditions and it is the deepest sensible choice at ₹2.198 a millilitre. One bottle size, the 120 ML. One reed count, eight black fibre reeds. One load, the published 25%. One room, with its temperature recorded. One checkpoint calendar. Write all six on a single sheet and do not let any of them move for the duration, because changing one mid-programme ends the comparison. 10663 goes through holding everything else constant.
2
Draw the retention the moment the oil lands, before anything is blended12 ml of neat oil into a ₹36 attar bottle, capped, labelled with the supplier code, the date drawn and the date to reopen, stored cool and dark. If you blend first and retain later you have lost the reference permanently — there is no way to reconstruct what arrived. This is also the step where you weigh the delivered container on the ₹354 scale and photograph the seal, which costs nothing and settles arguments.
3
Blend both bottles in one session and rest them the published 24–48 hoursTwo 120 ml bottles per supplier: 90 ml of base and 30 g of their oil in each, mixed in the same 100 ML beaker, rested the stated 24–48 hours, bottled on the same afternoon. One goes into your hot room; its twin goes into the coolest dark cupboard you have. Same session, same beaker, same rest — otherwise the control is not a control, it is just another bottle.
4
Weigh cap-off on day 0 and then weekly, on fixed datesLiquid, reeds and bottle together, cap off, every time. Weekly rather than daily for a simple resolution reason: a ±1 g scale error on a 2 g daily signal is ±50%, but on a 14 g week it is ±7.1%. Use fixed checkpoint dates, not end dates — two bottles that finish on different days share only the earlier of the two day-counts, so comparing two endings compares almost nothing. Beside each weight write the date, the room temperature from the ₹354 pen thermometer, whether a fan or air-conditioner ran, and a one-line throw note.
5
Run the blind panel at every checkpoint, coded by somebody who is not judgingThree unlabelled vessels — two drawn from one bottle, one from the other, in random order, both at room temperature. The judge picks the odd one out. Record the count of correct identifications out of attempts, per checkpoint. Never write that an oil "held up" or "turned harsh"; those are not observations this page or any page is entitled to, and a count is both more honest and far more useful six months later when you are re-reading the file.
6
Add a plain-base blank once, and share it across every supplier rowOne bottle of base with no oil at all, same reed count, same room, same calendar. It costs ₹368.02 and it is the only clean way to separate carrier loss from fragrance contribution — without it every grams-per-day figure you have is the sum of two things you cannot pull apart. You need one blank for the whole programme, not one per supplier, which makes it the best-value bottle on the bench. 10671 covers the with-and-without-reeds version of the same logic.
The CSI principle
A bench run screens for change. It never predicts life. No accelerated result becomes a real-time claim, for any supplier, at any ratio.
A warm-cupboard week can show you cloudiness, separation, colour movement or an odour drift against a cool-stored control, and that is genuinely useful at goods-in and genuinely useful for shortlisting. What it cannot do is turn into "lasts sixty days", for your product or anyone's. A longevity figure comes from full-life trials on more than one unit, published conservatively with the room, season, airflow and reed count stated — and validated per fragrance, not once across a collection.
The scorecard, and what makes two rows comparable
One row per supplier, filled over months rather than in a week. The left-hand columns are what they gave you; the right-hand columns are what you measured. Only the right-hand columns are evidence, and only if the six comparability lines held.
The supplier row · eight columns, filled from two different sources
How each column is filled, how often, and what breaks it
| Column | Filled by | Cadence | What makes it comparable |
|---|---|---|---|
| Documents returned, out of four | Their reply to your ten lines | Once, then on any change | Identical wording sent to every supplier |
| Sample from the shipped lot | Them, physically | Every order | Yes or no — there is no partial credit here |
| Retention drawn and dated | You, at goods-in | Every delivery | Drawn before production, always neat oil |
| Grams lost per day, warm arm | Your scale, cap-off | Weekly, on fixed dates | Same base, bottle, reeds, load, room, dates |
| Grams lost per day, cool control | Your scale, same session's twin | Weekly, same dates | Filled in the same session as the warm arm |
| Blind count, out of attempts | A judge who did not code the vessels | Every checkpoint | Three vessels, random order, room temperature |
| Clarity observations | You, in your base at your load | After each rest, then weekly | Same glass, same light, same fill height |
| Dated notes on what changed | You, from their change notices | As it happens | A date and a sentence beats a recollection |
Two practical notes about reading this table. First, an empty right-hand side is not a failure, it is a non-entry — a supplier who sent no lot sample never got a row, and should not be compared against one that did. Second, the left-hand columns are a screening tool and the right-hand columns are the decision. Plenty of suppliers return all four documents and then produce a batch your blind panel can pick out at twenty paces; plenty of others answer slowly and ship consistently. The paperwork gets you to the bench. The bench decides.
Hold your own base constant even when you are also shopping for a base
It is tempting to qualify a new oil and a new base in the same round. Do not. The five CSI bases are all ₹1,099 per 500 ml except Longevity at ₹1,296, so a base swap is usually ₹0 a bottle and feels free — but it changes the one thing every supplier row has in common. Run the oil comparison on one fixed base, pick the oil, then run the base question separately with that oil fixed. 10642 covers what the base pages do and do not publish.The bench, line by line, and the marginal supplier
Here is what the programme actually costs, resolved into whole packs. The notional per-supplier figure and the real pack-resolved figure differ by more than most people expect, and the gap closes sharply as you add suppliers.
Three supplier rows · six bottles, three retentions, one shared instrument set
Notional per-unit cost against what the packs actually force you to buy
| Line | Needed | Notional at per-unit rates | Cheapest buyable route | Actual |
|---|---|---|---|---|
| Base | 540 ml | ₹1,186.92 | Two 500 ml packs · 1,000 ml | ₹2,198.00 |
| Glass, 120 ML | 6 bottles | ₹637.20 | One Pack of 10 | ₹1,062.00 |
| Black fibre reeds | 48 reeds | ₹384.00 | One Pack of 50 · beats two 25s by ₹72 | ₹400.00 |
| 12 ml retentions | 3 | ₹108.00 | One pack of ten | ₹360.00 |
| Subtotal, consumables | — | ₹2,316.12 | Whole packs only | ₹4,020.00 |
| Instruments | Scale, thermometer, beaker | ₹1,008.00 | One of each, reused forever | ₹1,008.00 |
| Total | 3 suppliers | ₹3,324.12 | — | ₹5,028.00 |
Worked out above: one bottle excluding the supplier's oil is 90 ml base × ₹2.198 (₹197.82) + glass ₹106.20 + eight reeds at ₹8.00 (₹64.00) = ₹368.02, so a supplier row of two matched bottles plus one ₹36 retention is ₹772.04. At the Pack-of-25 reed rate of ₹9.44 the same row is ₹795.08, ₹23.04 and 2.98% more. Six bottles need 540 ml of base — 40 ml past the largest listed 500 ml pack, which is why the base line doubles to two packs. Pack resolution adds ₹4,020 − ₹2,316.12 = ₹1,703.88, a 73.56% overhead on three rows. The instruments are the ₹354 scale, the ₹354 pen thermometer (only 19 units listed) and the ₹300 Silicon Measuring Beaker 100 ML — whose handle promises a 500 ml option that does not exist; the 250 ML is a separate ₹600 listing. Each supplier's own oil is the one line this page cannot price, and the only one that differs between rows.
Now the useful part, which is what the next supplier costs. Because the packs are already bought, the marginal row is almost free until a pack boundary arrives — and then it is not.
The marginal supplier · adding rows to packs already purchased
A staircase, not a line — budget by row position, not by average
| Row | Bottles in total | What runs out | What you buy | Marginal cost |
|---|---|---|---|---|
| Suppliers 1–3 | 6 | Everything, from zero | 2 base, 1 glass, 1 reed pack, 1 retention pack, 3 instruments | ₹5,028.00 |
| Supplier 4 | 8 | Reeds at 50 | One Pack of 25 | ₹236.00 |
| Supplier 5 | 10 | Reeds at 75 | One Pack of 25 | ₹236.00 |
| Supplier 6 | 12 | Base at 1,000 ml and glass at 10 | One base pack and one glass pack | ₹2,161.00 |
| The shared blank | +1, once | Nothing, if bought early | One bottle's worth from existing packs | ₹368.02 |
Worked out above: at eight bottles the base need is 720 ml and the glass need is 8 — both inside the 1,000 ml and 10 bottles already bought — but reeds reach 64 against the 50 in hand, so one Pack of 25 at ₹236 covers it. At ten bottles the base is 900 ml and glass is 10, still inside; reeds reach 80 against 75, so another Pack of 25 at ₹236. At twelve bottles the base reaches 1,080 ml and the glass 12, so both cross their boundaries at once: ₹1,099 + ₹1,062 = ₹2,161, a 9.16× step on the row before it. The lesson is the same one that governs every trial in this series: budget by row position, not by average, and if you expect six suppliers, buy the sixth row's packs with the first three rather than discovering the boundary later. 10685 works the same staircase for fragrance arms rather than supplier rows.

₹354 · nothing on this page works without it
Candle Making Weighing Scale
The entire supplier comparison reduces to one measurement taken repeatedly: the weight of a bottle, cap off, on a fixed date. At ₹354 this is the cheapest line in the programme and the only one without which none of the rest means anything — a blind panel without a weight log tells you two oils smell different, not which one is leaving the bottle faster. Buy it before you request a single sample. It serves three jobs here: net weight at goods-in on every delivered container, the weekly cap-off weight on every arm, and the final check on how much liquid a bottle had left when you stopped recording. Live stock is comfortable at 98 units. Weigh weekly rather than daily — a ±1 g error on a 2 g daily signal is ±50%, against ±7.1% on a 14 g week.

The one listed instrument that fills the temperature column
Pen Thermometer For Candle Making
Every temperature in this series is the reader's own, and this is the only listed instrument that produces one. At ₹354 it turns "it was hot that week" into a figure beside a weight, which is the difference between a log somebody else can read and a note only you understand. Two reasons it matters specifically for supplier comparison. A row recorded at an unknown temperature cannot be compared with a row recorded at a known one, so without this the comparability rule simply fails. And when a supplier asks why you are holding a batch, "33 °C recorded on each of these four dates, these grams lost per day, these blind counts" is a conversation; "it felt worse this time" is not. Stock is thin at 19 units, which is worth knowing if you are equipping more than one site.

₹36 · the only fixed point in the whole programme
Attar Bottles ( 3ml, 6ml, 12 ml)
The 12 ml bottle at ₹36 — ₹360 for a pack of ten — is the cheapest sealed vessel in the range and the single highest-leverage purchase in a supplier comparison. Draw one from every delivery, neat, before production starts; label it with the supplier code, the date drawn and the date to reopen; keep it cool and dark. Three suppliers across four deliveries each is twelve retentions, two packs at ₹720, and it makes every consistency question for the next year answerable instead of rhetorical. One live-listing note: the title reads "Attar Bottles ( 3ml, 6ml, 12 ml)" while the handle promises a 2 ml — there is no 2 ml variant. The three sizes are 3, 6 and 12 ml, all packs of ten, all deep in stock. Use the 12 ml for neat oil retentions and the 6 ml if you also want to retain finished blend.
| Size | Price | Per bottle | Live packs |

The constant that makes two supplier rows comparable
Pure Performance Reed Base Oil — Professional Reed & Car Diffuser Base
The comparison needs one base, held still, for every row — and this is the sensible default because its page is the only one in the range that addresses the conditions you are testing for, in CSI's own words: it "performs well in Indian climates by balancing scent throw with longevity" and notes that "heat and humidity create specific challenges". Those are qualitative statements and that is the honest position: no rate, no multiplier, no temperature, no viscosity and no evaporation figure appears on this or any base page. It publishes the range's standard numbers — blend with 10-30% fragrance oil, a 25–30% working ratio, a 24–48 hour rest before bottling — and carries two things worth naming. Its dose cards mark 20% as "Recommended" while its details table says 70–75% base with 25–30% oil, and its two FAQ copies disagree with each other; named, not resolved. And it publishes no composition and no alcohol-free statement, only "no added fixatives / no complex enhancements" — so alcohol-free is an inference from the shelf, not a published fact, and a label claim needs requested documentation.

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished diffusers. A page about choosing between suppliers, written by a supplier, is only worth reading if it is willing to say the inconvenient thing — so here it is: we publish no heat-stability data either. Not a flash point used as a working temperature, not a volatility, not a shelf life. Any supplier who hands you one of those for a reed diffuser oil is handing you a claim, and the right response is the same whoever it comes from: ask for the documents, draw a retention, and put a bottle on a scale.
Every price, pack size and per-variant stock figure here was read live from candlemakingsuppliesindia.store in October 2026 and links to the product page, where current pricing always takes precedence. Stated specifications are quoted only where a page publishes them: the bases' 10-30% blend range, 25–30% working ratio and 24–48 hour rest; Pure Performance's "performs well in Indian climates by balancing scent throw with longevity" and "heat and humidity create specific challenges"; the fibre reeds' 20.3 cm length, 4–5 / 6–8 / 10+ count bands, "flip every 3-5 days", "1-2 hours initial absorption", "does not swell in heat or humidity" and "avoid placing in direct sunlight or near heat sources which accelerate evaporation". Those are CSI's own words and none is a rate. Not published anywhere in the range and not stated, estimated or implied here: any temperature, flash point used as a working temperature, viscosity, volatility, evaporation rate, heat-stability statement, storage temperature, shelf life, density, composition, alcohol-free statement, batch code, lot code, variation tolerance or specification sheet — nor any lead time, dispatch window, courier, credit term or minimum order quantity, the single published MOQ in the range being a 12 ml car bottle's "Minimum Order: 12 pcs". Documentation is available on request and is never summarised. Blend ranges are formulation ranges, not safety limits, and nothing here is certified or approved by IFRA on CSI's behalf.

Frequently asked questions
Which Indian supplier has the most heat-stable reed diffuser fragrance oils?
Nobody can answer that from published information, and that includes us. CSI publishes no temperature data of any kind for any oil, base, reed or bottle, and we have not found an auditable heat-stability figure published for reed diffuser oils anywhere in this market. A number given in a message or printed without a method is a claim, not a specification.
So the comparison is built from three things you own: what each supplier returned in writing against an identical ten-line request, a sealed 12 ml retention at ₹36 drawn from every delivery, and your own bench — two matched 120 ml bottles per supplier, one in your recorded hot room and one cool-stored from the same session, weighed cap-off on fixed dates. That is ₹772.04 a supplier excluding their oil, and it produces evidence rather than opinion.

That is ₹772.04 a supplier excluding their oil, and it produces evidence rather than opinion.
What should I ask a fragrance oil supplier before placing a wholesale order?
Ten things, in writing, worded identically to every supplier: the exact product and grade; a safety data sheet; IFRA documentation as issued; an allergen declaration; a batch or lot identifier on every container; the date of manufacture for the lot shipping; a pre-shipment sample drawn from that lot; notice before any change of composition and what counts as one; the storage condition they themselves recommend; and one named person who signs the rest.
Notice what is not on that list: a performance figure. Do not ask whether an oil is "stable at 40 °C", because nobody holds that number and the answer will be a guess that then behaves like a specification in your file. Documentation is available on request and is never summarised — you receive it, file it intact, and hand it to a qualified adviser.

How do I know whether this month's batch matches last month's?
Only if you kept a retention, which is why ₹36 is the best money in this whole programme. Draw 12 ml of neat oil from every delivery before production starts, cap it, label it with the supplier code and two dates — drawn and due to reopen — and store it cool and dark.
Then the test is a coded blind same-or-different: three unlabelled vessels, two drawn from one sample and one from the other, in random order, both at room temperature, coded by somebody who is not judging. The judge picks the odd one out and you record the count correct out of attempts. That count is a result. "It smells the same to me" is not, and neither is any adjective — no page here will tell you an oil "holds up" or "goes off", because nobody writing it has smelled these oils and no catalogue ranks two of them for stability.

Can a short high-temperature test tell me which supplier's oil lasts longer?
No, and this is the rule that matters most in the whole exercise. A short warm-cupboard run is a screening tool for change — cloudiness, separation, colour movement, an odour drift against a cool-stored control from the same filling session. That is genuinely useful for shortlisting and genuinely useful at goods-in.
What it is not is evidence about real-world life. No accelerated result converts into a days figure, for any supplier, at any ratio, ever. A longevity claim comes from full-life trials on more than one unit, published conservatively with the room, season, airflow and reed count stated, and validated per fragrance rather than once across a collection. Every temperature and every day-count in that work is yours, recorded as your own condition — there is no published figure to borrow.

What does it cost to compare three suppliers properly?
₹5,028, excluding the suppliers' own oil, resolved into whole packs: two 500 ml base packs (₹2,198 — six bottles need 540 ml, which is 40 ml past one pack), one Pack of 10 of the 120 ml glass (₹1,062), one Pack of 50 black reeds (₹400, beating two Pack-of-25s by ₹72), one pack of ten 12 ml retention bottles (₹360), plus the ₹354 scale, the ₹354 pen thermometer and the ₹300 100 ML beaker.
The notional per-unit figure is ₹3,324.12, so pack resolution adds ₹1,703.88 — a 73.56% overhead at three rows. It falls away fast: suppliers four and five cost ₹236 each because only the reeds run out, and then supplier six costs ₹2,161 when the base and glass packs both run out at once. Budget by row position, not by average, and buy the sixth row's packs with the first three if you expect six.

Are CSI's reed diffuser bases alcohol-free?
Alcohol-free is the shelf's default inference, not a published fact, and the distinction matters if you intend to print it. The Pure Performance page publishes no composition, no ingredient list and no alcohol-free statement — only "no added fixatives / no complex enhancements". No perfumer's alcohol is listed anywhere in the range, which is where the inference comes from; the one alcohol listing is isopropyl alcohol spray 150 ml, a different product entirely.
If a label claim depends on it, it needs requested documentation rather than a reasonable deduction — and that is exactly the kind of line that belongs in your ten-line letter to every supplier, ours included. CSI also lists no DPG, no DPM, no CCT and no individual solvents, so a carrier-ratio specification cannot be built from listed components either; the five ready-made bases are the route.
