I Want to Source Summer-Compatible Reed Diffuser Fragrance Oils Wholesale From Candle Making Supplies India — How Do I Choose Samples, Validate Formulas and Plan Bulk Orders?
Most CSI oils list five pack rungs, and each rung funds a different decision rather than a different quantity. A 15 g rung cannot fill one 120 ml bottle. A 100 g rung funds a three-bottle replicate set exactly. A kilo funds thirty-three bottles. Plan the rungs and the bulk order plans itself.

what the sample rung plus the validation rung costs as a share of the 15 kg production order they de-risk, on British Rose — ₹436.60 against ₹46,020. Across seven oils the band is 0.79% to 2.10%, and the outlier is a rung problem, not an oil problem · CSI live pricing, October 2026
Quick answers — read this first
How much oil should I sample? Enough to fill the vessel you will judge it in. At 120 ml and the published 25% ratio a bottle takes 30 g, so a 15 g rung is half a bottle and cannot fund even one 120 ml arm with a 12 ml retained reference beside it — that needs 15.5 g. The 100 g rung is the smallest that funds a three-bottle replicate set: 90 g in glass plus 3 g retained, with 7 g spare.Is sampling expensive? No, and this is the number worth internalising. On British Rose, a 15 gm sample and a 100 gm validation pack cost ₹436.60 against a ₹46,020 production order — 0.95%. On Citrus Lemon it is 0.90%, on Verbena 0.98%, on Eucalyptus Spearmint 0.92%. Sampling is not where your money goes.
Where does it go wrong, then? On the rung, not the oil. Citronella's 100 g rung costs ₹7.67 a gram against ₹2.891 at its kilo — 2.65× — so validating on its 100 g pack pushes the sampling share to 2.10%. On that oil the 500 g pack at ₹1,475 is cheaper in absolute money than two 100 g packs at ₹1,534.
And the bulk order? 1 kg is the largest listed oil pack, so 5 kg and 25 kg are not listed options — they resolve into packs, and anything larger is a quote. Check total listed stock before you design: Blue Ocean's whole ladder is 14.875 kg and Vetiver's is 10.195 kg, against 15 kg for a 500-bottle run.
Can I shortcut the validation with a hot cupboard? You can screen with one. You cannot claim with one. A short run at a raised temperature tells you something changed; it never establishes sixty days in a customer's home.
The short answer
Buy the rung that funds the decision. 15 g is half a 120 ml bottle and 1.2 bottles at 50 ml. 50 g is one 120 ml arm plus a reference. 100 g is a replicate set. 500 g is sixteen bottles. 1 kg is thirty-three. Match the rung to the question, not to the discount.
Price the exact quantity, every time. Per-gram columns mislead. A 2 × 2 run plus two references needs 126 g, and on British Rose the cheapest buyable route is 100 gm + 50 gm at ₹554.60 — ₹1,038.40 less than the 500 gm pack for the quantity actually needed.
Ladders have four shapes. Falling at every rung, flat above a floor, a cliff at one step, and inverted upward. Blue Ocean's cheapest gram is its 50 g rung and its kilo saves nothing, so on that oil climbing the ladder costs money.
Check stock in grams before you design. Total listed stock, summed across all five rungs, is the real ceiling: 165.4 kg on Citronella, 41.7 kg on Citrus Lemon, 14.875 kg on Blue Ocean and 10.195 kg on Vetiver. A 500-bottle run at 120 ml and 25% needs 15 kg.
In this guide
Rupees per gram is pack price ÷ pack grams, from live October 2026 prices. British Rose falls smoothly — ₹6.29333, ₹4.248, ₹3.422, ₹3.186, ₹3.068 — so every step up is cheaper than the one below. Citronella holds at ₹7.67 across both its 50 g and 100 g rungs and then drops 61.5% in a single step to ₹2.95 at 500 g, which means its 100 g pack is the most expensive place on its whole ladder to buy a validation quantity. Nothing on this chart says anything about how either oil smells or behaves in heat; it is a purchasing diagram.

How do I move a summer reed diffuser oil from sample to validated formula to bulk order?
Climb the rungs, and make each rung answer one question. Rung 1, the sample: most CSI oils open at a 15 gm pack from ₹68.44, but at 120 ml and the published 25% ratio that is half a bottle — one 120 ml arm with a 12 ml retained reference needs 33 g, so the real entry rung for a 120 ml product is the 50 g pack. At 50 ml it is different: 15 g funds 1.2 bottles. Rung 2, the replicate set: the 100 g rung funds three 120 ml bottles (90 g) plus one reference (3 g) with 7 g spare, and that is the smallest honest comparison — one bottle is an anecdote. Rung 3, the two-condition run: two replicates in each of two conditions is four bottles, 120 g, plus two references, so 126 g — on British Rose the cheapest buyable route is 100 gm plus 50 gm at ₹554.60, not the ₹1,593 500 gm pack. Rung 4, the pilot: 500 g funds sixteen 120 ml bottles and 1 kg funds thirty-three. Rung 5, production: a 500-bottle run at 120 ml and 25% is 15 kg, which on British Rose is fifteen kilo packs at ₹46,020 — and its 1 kg rung is at 17 packs, so that is tight rather than comfortable. The whole sampling and validation stage costs ₹436.60, or 0.95% of the production order. The thing to check before any of it is total listed stock in grams: Blue Ocean's entire ladder is 14.875 kg and Vetiver's is 10.195 kg, both short of one 500-bottle run.
One line: the rung decides what you can conclude, so buy the rung that funds the vessel — and price the exact quantity rather than reading the per-gram column.

What each rung actually funds
A rung is not a quantity of oil. It is a quantity of answer.
Start from the vessel and work backwards. At the published 25% ratio a 120 ml bottle takes 30 g of oil and a 50 ml bottle takes 12.5 g, and a 12 ml retained reference takes 3 g. Those three numbers convert every pack rung on the store into a number of experiments — which is the only unit that matters when you are deciding what to buy.
Published 25% ratio · 30 g per 120 ml bottle, 12.5 g per 50 ml bottle, 3 g per 12 ml reference
Five rungs, five decisions
| Rung | 120 ml bottles | 50 ml bottles | What it funds | What it cannot fund |
|---|---|---|---|---|
| 15 g | 0.5 | 1.2 | One 50 ml arm plus a reference — just barely not: that needs 15.5 g | Any 120 ml arm at all. Half a bottle is not an experiment |
| 50 g | 1.67 | 4 | One 120 ml arm plus a reference (33 g), 17 g spare. Or four 50 ml arms exactly | A replicate. One bottle gives you an anecdote and a photograph |
| 100 g | 3.33 | 8 | Three 120 ml bottles plus a reference (93 g), 7 g spare — the smallest real replicate set | A two-condition run: that needs 126 g, so add a 50 g pack |
| 500 g | 16.67 | 40 | Sixteen 120 ml bottles — two sizes, two conditions, two replicates, with spare | A production run. Sixteen bottles is a programme, not a batch |
| 1 kg | 33.33 | 80 | A thirty-three bottle pilot batch at 120 ml — enough to put product in front of customers | 500 bottles. That is 15 kg, which is fifteen of these |
Worked out above: bottles = pack grams ÷ 30 at 120 ml and ÷ 12.5 at 50 ml, both at the published 25% ratio. A 12 ml retained reference at 25% is 9 ml of base and 3 g of oil, so a one-arm-plus-reference cell at 120 ml is 33 g and at 50 ml is 15.5 g — half a gram more than the 15 g rung supplies. A three-bottle replicate set plus one reference is 93 g. A 2 replicate × 2 condition run is four bottles = 120 g, plus two references = 126 g. A 500-bottle run at 120 ml and 25% is 500 × 30 = 15,000 g. 1 kg is the largest listed oil pack and 500 ml the largest listed base pack, so 5 kg and 25 kg resolve into packs and anything larger is a quote.
The mistake: buying a 15 g sample for a 120 ml product. It is the cheapest line on the page and it funds nothing you can judge — half a bottle, no reference, no replicate. What makes it worse is that it is often the dearest gram on the whole ladder: Vetiver's 15 gm is ₹12.508 a gram against ₹5.664 at its kilo, a 2.21× entry penalty, and Citronella's is ₹9.44 against ₹2.891. So you pay the worst rate for a quantity that cannot answer the question. Fix: if you make 120 ml bottles, the entry rung is 50 g. If you make 50 ml bottles, 15 g funds 1.2 bottles and is a genuine sample. Decide the vessel first.
There is one more reason the vessel comes first. Appearance work — clarity, sediment, colour drift, separation against a cool-stored control — needs no reeds and no large bottle, and a 12 ml sealed reference at ₹36 does it for 3 g of oil. That means the smallest rung has a real job after all: it funds the appearance screen. What it does not fund is anything about throw or consumption, because those need a reed surface and a measurable volume to lose. Split the question and the rung follows.
Choosing samples: the cheapest route to a testable quantity
Seven oils that serve a summer reed diffuser build, priced at their smallest listed rung and at the cheapest route to 100 g. The last column is the one that should make you suspicious of per-gram columns in general.
Seven oils · live rungs, October 2026
Entry ticket, cheapest route to 100 g, and the penalty for starting small
| Oil | Smallest rung | Cheapest route to 100 g | Top rung ₹/g | Entry penalty |
|---|---|---|---|---|
| Eucalyptus Spearmint | 15 gm ₹68.44 · ₹4.5627/g | 100 gm ₹354 | ₹3.068 | 1.49× |
| Citrus Lemon | 15 gm ₹81.42 · ₹5.428/g | 100 gm ₹300 | ₹2.832 | 1.92× |
| Blue Ocean | 15 gm ₹93.22 · ₹6.21467/g | Two 50 gm ₹494, beating the 100 gm at ₹495 | ₹4.956 | 1.25× |
| British Rose | 15 gm ₹94.40 · ₹6.29333/g | 100 gm ₹342.20 | ₹3.068 | 2.05× |
| Verbena | 15 gm ₹106.20 · ₹7.08/g | 100 gm ₹590 | ₹4.72 | 1.50× |
| Citronella | 15 gm ₹141.60 · ₹9.44/g | 100 gm ₹767 — its dearest useful rung | ₹2.891 | 3.27× |
| Vetiver | 15 gm ₹187.62 · ₹12.508/g | 100 gm ₹600 | ₹5.664 | 2.21× |
Worked out above: ₹/g is pack price ÷ pack grams. Entry penalty is the 15 gm rate ÷ the top rung's rate: 4.5627 ÷ 3.068 = 1.487×; 5.428 ÷ 2.832 = 1.917×; 6.21467 ÷ 4.956 = 1.254×; 6.29333 ÷ 3.068 = 2.051×; 7.08 ÷ 4.72 = 1.50×; 9.44 ÷ 2.891 = 3.265×; 12.508 ÷ 5.664 = 2.208×. Blue Ocean inverts at pack level — two 50 gm packs are ₹494 against ₹495 for one 100 gm, so the two-pack route is ₹1 cheaper and leaves a sealed spare for the retest. Thin rungs to know before you plan: British Rose 15 gm at 14 packs; Eucalyptus Spearmint 100 gm at 28; Blue Ocean 100 gm at 20, 500 gm at 4, 1 kg at 8; Vetiver 100 gm at 9, 500 gm at 3, 1 kg at 5; Citrus Lemon 1 kg at 3. CSI live pricing and per-variant stock, October 2026.
What a sample order should contain, and what it costs
Five oils at their 100 g rung is a sampling order of ₹2,353.20 on Eucalyptus Spearmint, Citrus Lemon, British Rose, Verbena and Blue Ocean (as two 50 gm) — fifteen 120 ml bottles' worth of oil, five coded references, and a five-arm appearance screen. Add ₹1,099 for a base, ₹1,062 for ten 120 ML bottles, ₹636 for 64 reeds and ₹1,368 of instruments and the whole bench is ₹6,518.20. That is the real entry cost of a summer development programme, and it is about one seventh of a single 15 kg oil order.
Validating the formula, rung by rung
Validation is not a bigger sample. It is the same blend in enough bottles that the spread is visible.
Once an oil survives the appearance screen, the question changes from "has it changed" to "how much liquid does it lose and how much does it smell of" — and that needs replicates, conditions and fixed checkpoints. Here is what the sampling-plus-validation stage costs against the bulk order it protects.
500-bottle run at 120 ml and 25% = 15 kg of oil
Sampling and validation as a share of the order they de-risk
| Oil | Sample + validation rung | Spend | 15 kg at the cheapest buyable route | Share |
|---|---|---|---|---|
| Blue Ocean | 15 gm ₹93.22 + 100 gm ₹495 | ₹588.22 | Unfillable — 14.875 kg is all that is listed | 0.79% if it could be |
| Citrus Lemon | 15 gm ₹81.42 + 100 gm ₹300 | ₹381.42 | 3 × 1 kg + 24 × 500 gm = ₹42,576 | 0.90% |
| Eucalyptus Spearmint | 15 gm ₹68.44 + 100 gm ₹354 | ₹422.44 | 15 × 1 kg = ₹46,020 | 0.92% |
| Vetiver | 15 gm ₹187.62 + 100 gm ₹600 | ₹787.62 | Unfillable — 10.195 kg is all that is listed | 0.93% if it could be |
| British Rose | 15 gm ₹94.40 + 100 gm ₹342.20 | ₹436.60 | 15 × 1 kg = ₹46,020, and the kilo rung is at 17 packs | 0.95% |
| Verbena | 15 gm ₹106.20 + 100 gm ₹590 | ₹696.20 | 15 × 1 kg = ₹70,800 | 0.98% |
| Citronella | 15 gm ₹141.60 + 100 gm ₹767 | ₹908.60 | 15 × 1 kg = ₹43,365 | 2.10% |
Worked out above: share = sampling spend ÷ production order. 588.22 ÷ 74,340 = 0.79%; 381.42 ÷ 42,576 = 0.90%; 422.44 ÷ 46,020 = 0.92%; 787.62 ÷ 84,960 = 0.93%; 436.60 ÷ 46,020 = 0.95%; 696.20 ÷ 70,800 = 0.98%; 908.60 ÷ 43,365 = 2.10%. Citrus Lemon's 15 kg cannot route through its kilo rung alone (3 packs), so 3 × ₹2,832 + 24 × ₹1,420 = ₹42,576 = ₹2.8384/g, which is ₹96 or 0.226% above its flat kilo rate. Blue Ocean's and Vetiver's shares are shown for comparison only: their entire listed ladders are 14,875 g and 10,195 g against 15,000 g required. Citronella is the outlier for a purchasing reason, not a quality one — its 100 g rung is ₹7.67/g against ₹2.891/g at the kilo, 2.65×, so the validation rung is the dearest gram on its ladder. On that oil, buy 500 g for ₹1,475 instead of two 100 g packs for ₹1,534: more oil, less money.
1
Write the vessel, the load and the reed count before you open a product pageFill, load, reeds, colour. At 120 ml and the published 25% ratio each bottle is 90 ml of base and 30 g of oil; at 50 ml it is 37.5 ml and 12.5 g. The published window on every CSI reed base is "Blend with 10-30% fragrance oil" with a stated 25–30% working ratio and a 24–48 hour rest before bottling. Without these numbers no rung can be chosen, because a rung is only meaningful as a number of bottles.
2
Buy the appearance screen at the smallest rung, and buy it for everything on the shortlistThree grams per 12 ml reference. Blend two references per oil from the same mix, rest them 24–48 hours as the base pages instruct, code them, and split: one cool, one at your test temperature. Photograph each against a white card on day 0. This is the cheapest gate in the whole programme and it eliminates candidates for a few hundred rupees.
3
Climb to the 100 g rung only for survivors, and run three bottles not oneThree 120 ml bottles from one 100 g pack, same base, same reed count, same fill. Weigh each on the ₹354 scale at fixed checkpoints and log the room temperature from the ₹354 pen thermometer beside every weight. Three bottles give you a spread; the spread is what tells you whether the fourth bottle would have behaved the same way. Weigh weekly, not daily — a ±1 g error on a 2 g daily signal is ±50%, on a 14 g week it is ±7.1%.
4
Add the second condition before you add the second fragranceTwo replicates in each of two conditions is four bottles and 126 g with references — so one 100 g pack plus one 50 g pack, priced for the quantity rather than for the rate. This is the first point at which you can say anything about how your product behaves differently in two rooms, and it is still under ₹600 of oil on most of these ladders.
5
Check the whole ladder's stock in grams before you design the product around the oilMultiply each variant's live quantity by its grams and sum. Citronella comes to 165.4 kg and Eucalyptus Spearmint to 150.85 kg; Blue Ocean comes to 14.875 kg and Vetiver to 10.195 kg, both under a single 500-bottle run. Buying a thin line out is also dearer than its top rung, because the small rungs dominate the bill. Message us with the shortlist and the run size and we will tell you what today's shelf covers.
6
Run the survivor to the end before you publish anythingDays of life is usable liquid ÷ your own measured grams per day, with both halves labelled as yours and the room, season, airflow and reed count written beside them. Validate per fragrance rather than once for a collection: two units in each of two conditions across five fragrances is twenty running bottles before a range can carry one published figure. Then buy the kilos.
Four ladder shapes, and how to read yours
Not every ladder rewards climbing. Two of these actively punish it.
Read every rung of a ladder before you plan an order on it, because the shapes differ more than the prices do. Four patterns cover almost everything on the shelf, and knowing which one you are on tells you where to buy and where to stop.

Prices behind the table: British Rose ₹94.40 / ₹212.40 / ₹342.20 / ₹1,593 / ₹3,068 — kilo ₹3,068 against two 500 gm ₹3,186, saving ₹118. Citrus Lemon ₹81.42 / ₹170 / ₹300 / ₹1,420 / ₹2,832 — kilo saves ₹8. Verbena ₹106.20 / ₹330.40 / ₹590 / ₹2,478 / ₹4,720 — kilo saves ₹236 against two 500 gm and ₹1,180 against ten 100 gm, so state the basis. Citronella ₹141.60 / ₹383.50 / ₹767 / ₹1,475 / ₹2,891 — the 500 gm at ₹1,475 is cheaper in absolute money than two 100 gm at ₹1,534, and the kilo saves ₹59 against two 500 gm. Woody Oud ₹93.22 / ₹271.40 / ₹453.12 / ₹2,265.60 / ₹4,531.20 — identical per gram from 100 gm up. Blue Ocean ₹93.22 / ₹247 / ₹495 / ₹2,478 / ₹4,956 — two 50 gm (₹494) beat the 100 gm (₹495), and the kilo saves ₹0. Santal Noir ₹166 / ₹499 / ₹919 / ₹4,599 / ₹9,120 — the 500 g at ₹9.198/g is dearer per gram than the 100 g at ₹9.19, and the kilo saves ₹78 against two 500 g and ₹70 against ten 100 g.
Three practical rules come out of this. On a falling ladder, buy the highest rung your run justifies — but check stock at that rung, because the top rung is often the thinnest. On a cliff, the rung below the cliff is a trap: Citronella's 100 g pack is where a careless validation order lands, and it costs 2.65 times the kilo rate. On a flat or inverted ladder, climbing buys you nothing: Woody Oud's kilo saves ₹0 against ten 100 g packs, and Blue Ocean's 50 g rung is its cheapest gram, so on those two there is no volume argument at all and the only reason to buy big is lot consistency. Which brings us to the one thing a ladder cannot tell you.
No rung tells you how an oil behaves in heat, and no bench run converts into a season. Nothing on these pages publishes a temperature, a viscosity, a volatility, an evaporation rate, a heat-stability statement, a storage temperature or a shelf life — not for any oil, base, reed or bottle in the range. So a hot cupboard is a change screen: you compare a warm reference against a sealed cool one from the same batch, coded, handed to you with the labels covered, and you answer "are these the same?" rather than "has it faded?". That is a real and useful result. What it is not is evidence that a finished bottle performs for sixty days in a customer's flat, and there is no multiplier that makes it one. One CSI oil page carries the phrase "Heat Stable"; there is no published figure behind it, so do not put it in front of a customer. The protocol and its limits are in the accelerated-stability post.
Planning the bulk order and its stock ceilings
Now the last rung. A 500-bottle run at 120 ml and the published 25% ratio is 15 kg of oil and 45 litres of base — 90 of the 500 ml base packs — plus 500 bottles of glass and 4,000 reeds. Here is what the oil line looks like across the seven, with the ceiling that actually binds.

| Verbena | 15 × 1 kg = ₹70,800 | ₹4.72 | 165.02 kg, 100 packs at the kilo | Comfortable |

Worked out above. Stock sums multiply each variant's live quantity by its grams: Citronella 1,365 + 4,550 + 9,500 + 50,000 + 100,000 = 165,415 g; Citrus Lemon 1,350 + 4,750 + 9,100 + 23,500 + 3,000 = 41,700 g; Eucalyptus Spearmint 750 + 2,300 + 2,800 + 45,000 + 100,000 = 150,850 g; Verbena 1,320 + 4,600 + 9,600 + 49,500 + 100,000 = 165,020 g; Blue Ocean 1,275 + 1,600 + 2,000 + 2,000 + 8,000 = 14,875 g; Vetiver 1,395 + 1,400 + 900 + 1,500 + 5,000 = 10,195 g. Buying a thin line out costs more per gram than its top rung because the small rungs dominate: Blue Ocean 85 × 93.22 + 32 × 247 + 20 × 495 + 4 × 2,478 + 8 × 4,956 = ₹75,287.70 ÷ 14,875 = ₹5.0614 against its ₹4.956 top rung (2.12% over); Vetiver 93 × 187.62 + 28 × 354 + 9 × 600 + 3 × 2,900 + 5 × 5,664 = 17,448.66 + 9,912 + 5,400 + 8,700 + 28,320 = ₹69,780.66 for 10,195 g = ₹6.8446/g, which is 20.8% above its ₹5.664 kilo rate — its first 6.5 kg comes from the kilo and 500 gm rungs at ₹37,020 (₹5.6954/g) and everything after that costs far more. British Rose's 500 gm inventory count of 7,085 looks like a placeholder, so no depth claim is built on it. 45 litres of base is 90 of the ₹1,099 packs = ₹98,910; 500 bottles is 50 packs of the 120 ML glass = ₹53,100 against 24 packs live; 4,000 reeds is ₹32,000 at ₹8.00, routed as 8 × Pack of 500.
Two things to settle before the order goes in. First, the base. CSI's Depth page lists "Fresh citrus, light florals, aquatics" under Avoid and routes them to Lift, whose stated purpose is "citrus, green, bright florals" — so if your summer shortlist is citrus and aquatic, the base claiming to slow evaporation is the one the page itself steers you away from. Second, the honesty that has to travel with any base upgrade: a slower-evaporating base is not automatically a better base. If it restricts wicking or fragrance release the bottle lasts longer and smells of less, which looks like a win on a day count and reads like a complaint in a review. So judge any base change on two readings from the same bottles — grams lost per day, and a coded intensity note against a sealed cool-stored control — and remember that Depth, Lift, Softness and Pure Performance are all ₹1,099, so switching between them costs ₹0 a bottle; only Longevity carries a premium, ₹35.46 at 25% in a 120 ml bottle.
Ask for a lot number, not a longevity figure
When you place the bulk order, ask in writing whether the production quantity is drawn from the same lot as the sample you validated, and ask for the lot or batch number of what ships. Documentation is available on request and it is your document to read with a qualified adviser — nothing here summarises it, states a category maximum, or names a limit for any CSI oil, and the published 10-30% blend range is a formulation window on a base page rather than a safety limit. What you should not ask any supplier for is a days-of-life number. That one is yours: usable liquid ÷ your own measured grams per day.
Four lines to start with
Three oils with three genuinely different ladder shapes, and the base CSI's own copy routes a citrus or aquatic formula to. Every variant, its live stock and the published specification where a page states one.
1
The cliff · and the clearest rung lesson on the store
Citronella Fragrance Oil
A classic Indian warm-weather name whose ladder behaves like nothing else in the range. It holds flat at ₹7.67 a gram across both the 50 gm and 100 gm rungs, then drops 61.5% in one step to ₹2.95 at 500 gm and ₹2.891 at the kilo. Two consequences. First, the 500 gm pack at ₹1,475 is cheaper in absolute money than two 100 gm packs at ₹1,534 — buy five times the oil for ₹59 less. Second, a validation order placed at the 100 g rung on this oil costs 2.65 times the kilo rate, which is the whole reason this page is about rungs rather than oils. Stock is deep and even across every rung, which is unusual: 91 / 91 / 95 / 100 / 100 packs, a total of 165.4 kg. No temperature, volatility or evaporation figure is published for it or for any oil in the range.

The smooth ladder · every step up is cheaper
British Rose Fragrance Oil
The easiest ladder in this set to plan on: ₹6.29333 a gram at 15 gm falling without a single inversion to ₹3.068 at the kilo, with the kilo saving ₹118 against two 500 gm packs. That is the shape you want when a run size is still moving, because whatever quantity you land on, the next rung up is cheaper per gram. Two cautions. Its 15 gm rung is at 14 packs, so a wide multi-oil sample order may not be fillable at that rung, and its 500 gm inventory figure looks like a placeholder, so treat depth there as unconfirmed. For a 15 kg run its 1 kg rung at 17 packs leaves exactly two spare — fillable, but worth a message before you design a product around it. A CSI customer, Arshad Shaikh, writes that the "Fragrance oil is sooo good smell so good we love it a lot"; that is a candle observation, not a diffuser measurement.
| Size | Price | Per gram | Live packs |
|---|---|---|---|
| 15 gm | ₹94.40 | ₹6.29333 | 14 |
| 50 gm | ₹212.40 | ₹4.248 | 87 |

The inverted ladder · where climbing buys nothing
Blue Ocean Fragrance Oil
The counter-example, and a useful one. Its cheapest gram is the 50 gm rung at ₹4.94, after which the ladder rises slightly and flattens — ₹4.95 at 100 gm, ₹4.956 at 500 gm and at the kilo, which saves ₹0 against two 500 gm packs. At pack level that means two 50 gm packs (₹494) beat one 100 gm pack (₹495), and the two-pack route leaves you a sealed spare for the retest. So there is no volume argument on this oil at all; the only reason to buy a larger pack is lot consistency. The hard constraint is stock: its entire listed ladder across all five rungs is 14,875 g, which covers a 495-bottle run at 120 ml and 25% but not a 500-bottle one, and buying the line out would cost ₹75,287.70, or ₹5.0614 a gram — 2.12% above its own best rate. Fine for trials and smaller runs; message us before committing a product to it. Yashvi Shah's review calls it "Fresh and soothing", on a candle.
| Size | Price | Per gram | Live packs |

The base CSI's own copy routes citrus and aquatics to
Lift Base — Professional Grade Reed & Car Diffuser Base (500 ml)
A single variant at ₹1,099 for 500 ml = ₹2.198 a millilitre, identical to Depth, Softness and Pure Performance — so choosing it over any of those three costs ₹0 a bottle. Its stated purpose is "citrus, green, bright florals", and it matters here because the Depth page — the only base page claiming to "slow evaporation" — lists fresh citrus, light florals and aquatics under Avoid and sends them to this one. If your summer shortlist is lemon, verbena, citronella or an aquatic, that routing is the store's own guidance and it points away from the slow base. Published like every reed base: "Blend with 10-30% fragrance oil", a 25–30% working ratio, a 24–48 hour rest before bottling. Named, not resolved: the dose cards mark 20% as "Recommended" while the details table says 70–75% base with 25–30% oil. Stock is 66 packs, which funds 366 bottles at 120 ml and 25% — ask us before a 500-bottle run. One CSI customer, Sooraj R, records "Good product👍".
| Base | Price | Per ml | Live packs |
|---|---|---|---|
| Lift 500 ml | ₹1,099.00 | ₹2.198 | 66 |
| Depth 500 ml | ₹1,099.00 | ₹2.198 | 982 |
| Softness 500 ml | ₹1,099.00 | ₹2.198 | 98 |

Priced above: Citronella ₹141.60 / ₹383.50 / ₹767 / ₹1,475 / ₹2,891 (91 / 91 / 95 / 100 / 100). British Rose ₹94.40 / ₹212.40 / ₹342.20 / ₹1,593 / ₹3,068 (14 / 87 / 69 / placeholder / 17). Blue Ocean ₹93.22 / ₹247 / ₹495 / ₹2,478 / ₹4,956 (85 / 32 / 20 / 4 / 8). Lift 500 ml ₹1,099 (66); Depth ₹1,099 (982); Softness ₹1,099 (98); Pure Performance 500 ML ₹1,099 (56) and 100g ₹325 (63); Longevity ₹1,296 (40). Lift's 66 packs = 33,000 ml ÷ 90 ml a bottle = 366 bottles at 120 ml and 25%. The ₹325 100 g base pack is priced by mass and the 500 ml packs by volume, and no density is published, so the two cannot be reduced to one per-unit price. CSI live pricing and per-variant stock, October 2026.
The CSI principle
Choose the rung, not the discount. A rung that cannot fill your vessel cannot answer your question, however cheap the pack looked.
Sampling and validation cost about one per cent of the order they protect, so the money is never the reason to skip them. The reason people skip them is that they bought a 15 g pack for a 120 ml product and found it answered nothing. Start from the bottle, convert to grams, and the ladder tells you where to buy.
Ready for the production rung? 15 kg of oil, 90 of the ₹1,099 base packs, 50 packs of the 120 ML glass and 4,000 reeds at ₹8.00 is a 500-bottle run. Glass is the line to check first — 24 packs, 240 bottles, are live — and the largest listed oil pack is 1 kg, so 5 kg and 25 kg resolve into packs and anything larger is a quote. Bulk pricing and GST invoicing are handled on WhatsApp.

The sample was never the expensive part. Buying the wrong rung twice is.

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished diffusers. No oil on this page is described as holding or losing its character in heat, and no two oils are ranked for stability — those are panel judgements belonging to whoever is holding two coded bottles, not claims a supplier can make. CSI publishes no temperature data of any kind for any base, oil, reed or bottle: no flash point used as a working temperature, no viscosity, no volatility, no evaporation rate, no heat-stability statement, no storage temperature and no shelf life. One oil page carries the phrase "Heat Stable" with no figure behind it, and we have told you not to repeat it.
Every price, variant title and per-variant stock figure was read from live CSI data 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: "Blend with 10-30% fragrance oil", the 25–30% working ratio and the 24–48 hour rest on the reed bases; Lift's "citrus, green, bright florals"; Depth's "slows evaporation" and its Avoid list; 20.3 cm and the 4–5 / 6–8 / 10+ count bands on the fibre reeds. Where a page contradicts itself — the base pages' 20% dose card against their 25–30% details table — we name it and route you to us. Several inventory figures in this range look like placeholders rather than counts, and where we think so we have said so instead of building a depth claim on them.
CSI lists fibre reed sticks and no rattan reeds at all, and no 100 ml or 200 ml reed bottle. Documentation is available on request and is never summarised here; compliance and labelling are matters for a qualified adviser. For bulk pricing, GST invoicing, documentation or live stock in grams across a shortlist, message us on WhatsApp at +91 7397976926.
Frequently asked questions
What size sample should I order for reed diffuser testing?
Work back from the bottle. At the published 25% ratio a 120 ml diffuser takes 30 g of oil and a 50 ml takes 12.5 g, and a 12 ml retained reference takes 3 g. So for a 120 ml product the 15 g rung is half a bottle and the real entry rung is 50 g, which funds one arm plus a reference with 17 g spare. For a 50 ml product, 15 g funds 1.2 bottles and is a genuine sample. The 100 g rung is the smallest that funds a three-bottle replicate set — 90 g in glass plus 3 g retained, 7 g spare — and a replicate is what separates a result from an anecdote.
How much does sampling and validation cost compared with the bulk order?
Much less than people expect. A 15 gm sample plus a 100 gm validation pack against a 15 kg production order works out at 0.90% on Citrus Lemon, 0.92% on Eucalyptus Spearmint, 0.95% on British Rose and 0.98% on Verbena. The one outlier is Citronella at 2.10%, and that is a rung problem rather than an oil problem: its 100 g rung is ₹7.67 a gram against ₹2.891 at its kilo. On that oil, buy the 500 gm pack at ₹1,475 instead of two 100 gm at ₹1,534 — more oil for less money.
Is the biggest pack always the cheapest per gram?
No, and assuming so is the commonest costing error in this range. Ladders come in four shapes. Falling — British Rose, Citrus Lemon and Verbena drop at every rung. Cliff — Citronella holds at ₹7.67 through two rungs then falls 61.5% in one step. Flat above a floor — Woody Oud is identical at ₹4.5312 from 100 gm up and its kilo saves ₹0. Inverted — Blue Ocean's cheapest gram is its 50 g rung, and two 50 gm packs at ₹494 beat one 100 gm at ₹495. Always price the exact quantity you need across pack combinations rather than reading a per-gram column.
Can CSI supply 5 kg or 25 kg of one fragrance oil?
1 kg is the largest listed oil pack and 500 ml the largest listed base pack, so 5 kg and 25 kg are not listed options — they resolve into whole packs, and anything beyond what the rungs cover is a quote rather than a catalogue line. The binding question is total listed stock. Summed across all five rungs, Citronella is 165.4 kg and Verbena 165.02 kg, while Blue Ocean is 14.875 kg and Vetiver 10.195 kg — both short of the 15 kg a 500-bottle run at 120 ml needs. Message us with the shortlist and the run size and we will confirm what today's shelf covers.
Which base should I validate the formula on?
The one your oil family points at, and then hold it constant. CSI's Depth page lists "Fresh citrus, light florals, aquatics" under Avoid and routes them to Lift, so for a lemon or aquatic formula the base claiming to slow evaporation is the one the page itself steers away from. Depth, Lift, Softness and Pure Performance are all ₹1,099 — ₹2.198 a millilitre — so switching between them costs ₹0 a bottle. And treat the premium base carefully: a slower-evaporating base is not automatically a better base. If it restricts wicking or release, the bottle lasts longer and smells of less, so judge it on grams lost per day and a coded intensity note against a cool-stored control.
Can I validate a summer formula faster with a 40 °C test?
You can screen faster. You cannot validate faster. A short run at a raised temperature is a change screen: you compare a warm reference against a sealed cool one from the same batch, coded and handed to you with the labels covered, and answer whether they are the same. It will eliminate candidates cheaply, which is worth a great deal. What it will not do is establish sixty days of real-world performance, because no published relationship exists between a bench temperature and real-world life for anything in this range — CSI publishes no temperature figure for any of it. A longevity claim comes from running real bottles to the end: usable liquid ÷ your own measured grams per day, validated per fragrance before one range goes on a collection.

Figures verified October 2026: Rung capacities at the published 25% ratio — 30 g per 120 ml bottle, 12.5 g per 50 ml bottle, 3 g per 12 ml reference; so 15 g = 0.5 and 1.2 bottles, 50 g = 1.67 and 4, 100 g = 3.33 and 8, 500 g = 16.67 and 40, 1 kg = 33.33 and 80. One arm plus a reference is 33 g at 120 ml and 15.5 g at 50 ml; a replicate set plus a reference is 93 g; a 2 × 2 run plus two references is 126 g, cheapest on British Rose as 100 gm + 50 gm = ₹554.60 against ₹1,593. Sampling shares: 588.22 ÷ 74,340 = 0.79%; 381.42 ÷ 42,576 = 0.90%; 422.44 ÷ 46,020 = 0.92%; 787.62 ÷ 84,960 = 0.93%; 436.60 ÷ 46,020 = 0.95%; 696.20 ÷ 70,800 = 0.98%; 908.60 ÷ 43,365 = 2.10%. Entry penalties 1.49× / 1.92× / 1.25× / 2.05× / 1.50× / 3.27× / 2.21×. Citronella's 100 g to 500 g step falls 61.5% (₹7.67 to ₹2.95) and its 500 gm at ₹1,475 is ₹59 under two 100 gm at ₹1,534; Citronella's kilo saves ₹59 against two 500 gm. Kilo savings: British Rose ₹118, Citrus Lemon ₹8, Verbena ₹236 against two 500 gm and ₹1,180 against ten 100 gm, Woody Oud ₹0, Blue Ocean ₹0, Santal Noir ₹78. Blue Ocean pack inversion ₹494 against ₹495. Stock sums 165,415 g, 41,700 g, 150,850 g, 165,020 g, 14,875 g and 10,195 g; Blue Ocean's buy-out ₹75,287.70 = ₹5.0614/g, 2.12% over ₹4.956. A 500-bottle run at 120 ml and 25% = 15 kg of oil, 45 L of base (90 packs, ₹98,910), 500 bottles (50 packs, ₹53,100, against 24 packs live) and 4,000 reeds (₹32,000). Lift's 66 packs fund 366 bottles. Every temperature, duration, checkpoint and day-count in this method is the reader's own choice or observation. CSI publishes no temperature, viscosity, volatility, evaporation-rate, heat-stability, storage-temperature, shelf-life or density figure for any base, oil, reed or bottle, and none is stated, estimated or implied here. No oil is described as holding or losing its character in heat, and no two oils are ranked for stability. Several inventory counts in this range look like placeholders and are flagged rather than quoted as depth. The 10–30% blend range is the base pages' formulation window, not a safety or regulatory limit; compliance and labelling are matters for a qualified adviser. Prices and availability change — the linked product pages are always authoritative.
