Fast × Slow × 100 ml Product
A faster setup is bolder and empties sooner; a slower one lasts and is quieter. Neither is better until you decide the life you are selling. For a 100 ml product, 45 days means losing no more than 2.22 g a day — and still passing a blind room score.
2.22 g/day
the most a 100 ml fill (100 g at an example 1.00 g/ml) may lose on average to last 45 days — your life line on the target-zone map
Quick answers — read this first
Fast or slow base? Whichever lands your product in the target zone — long enough life, strong enough score. Decide both targets first.

Which CSI base is slower? Longevity's page claims slower "cold diffusion"; Depth mentions "slow diffusion". No CSI page claims fast, and none publishes an evaporation rate.

What else changes speed? Reed count, room temperature, airflow and the bottle opening. Reeds are the cheapest dial — the three dials.

Is the slower base worth it? Per day of use, only if it lasts at least 10.1% longer than the neutral base with Palo Santo at 22%.
The short answer
Answer: Choose by the life you are selling: convert it into a maximum g/day (45 days for a 100 ml fill = 2.22 g/day), set a blind-score strength target, and buy the base that meets both at the lowest cost per day.
Why: Faster release means more scent per day and a shorter life. CSI publishes no evaporation rates; Longevity's page claims slower diffusion, which is a claim to test.
Method: Ten 120 ml bottles at 22% by weight: Pure Performance with 6 reeds, Longevity with 6, Longevity with 8, plus a hold-back. Weigh days 0–28, score blind on days 7, 14 and 21, plot each bottle on the target-zone map.

With example targets of 45 days and a score of 3, a bottle must sit left of the life line and above the strength line. Each arm of the test is plotted bottle by bottle; the base or reed count that lands all three of its bottles in the zone wins.

Straight answer
How do I choose between a fast-evaporating reed diffuser base and a slower-evaporating base for a 100 ml product?
Decide the life you are selling first, turn it into a maximum grams per day, and buy the base — or the reed count — that meets that limit while still passing a blind room score. A 100 ml fill weighs about 100 g at an example 1.00 g per ml; to last 45 days it may lose no more than 2.22 g a day. Faster release gives a bolder room and a shorter life; slower gives a longer life and usually a quieter room — two different products, not better and worse. CSI publishes no evaporation rate for any base; Longevity's page claims slower "cold diffusion" and Depth's mentions "slow diffusion", while the neutral Pure Performance makes no speed claim. Reed count moves the same dial far more cheaply. Test Pure Performance with 6 reeds against Longevity with 6 and with 8, three 120 ml bottles each at 22% by weight, weighed from day 3 to day 21 and scored blind. With Palo Santo, Longevity must last at least 10.1% longer to match the neutral base per day. The round costs ₹4,172.00.
One line: set a life line and a strength line, then buy the base or reed count that lands inside both.
Decide the life you want first, then test. For a woody oil like Palo Santo, the CSI base whose page claims slower diffusion is Longevity Base (₹1,296.00 / 500 ml); test it with two reed counts against the neutral Pure Performance Base in a ten-bottle round costing ₹4,172.00 in bases, bottles and reeds with your own oil.
See Longevity Base

The short answer: choose the life you are selling, then the base that delivers it

"Fast" and "slow" are not better and worse. They are two products — a bolder bottle that empties sooner, and a quieter one that lasts.

A faster-evaporating setup puts more fragrance into the room per day and empties the bottle sooner. A slower one lasts longer and is usually quieter. For a 100 ml product, the right choice is whichever lands in your target zone: long enough to meet the life you promise, strong enough to pass a blind room score in the room you sell it for. So the first step is not choosing a base — it is writing down those two targets. A 100 ml fill at an example 1.00 g per ml is 100 g of liquid; if you promise 45 days, the bottle may lose no more than 2.22 g a day on average.

On the CSI side, only two base pages say anything about speed. Longevity Base's page claims slower "cold diffusion"; Depth Base's page mentions "slow diffusion". No CSI page describes a base as fast, and CSI publishes no evaporation rate for any of them. The neutral Pure Performance Base makes no speed claim at all. So the honest framing is not "fast base versus slow base" from a datasheet; it is a base whose page claims to be slower, tested against a neutral one — and a reed-count arm, because reed count moves the same dial and costs far less.

This page works through that test with Palo Santo — a woody, resinous oil in the families Longevity's page names — at 22% by weight, 100 ml in the 120 ml Gold Reed Diffuser Bottle 120 ml, and white fibre reeds. It ends with a rule that tells you which base to buy for the life you are selling, or whether to change reed count instead.

Your life target → the maximum average g/day · 100 g fill at the example density · ±5% density range in the last column
What a life promise means in grams per day
You promise That is Max average loss At 0.95–1.05 g/ml
30 days 4.3 weeks 3.33 g/day 3.17–3.50 g/day
45 days 6.4 weeks 2.22 g/day 2.11–2.33 g/day
60 days 8.6 weeks 1.67 g/day 1.58–1.75 g/day
90 days 12.9 weeks 1.11 g/day 1.06–1.17 g/day

If you have not yet shortlisted bases by fragrance family, start with the base-selection pillar; for the load side of the same trade, how much fragrance oil to add is the pillar. This page owns the choice of speed.

The CSI principle
Write the life target and the strength target first. The base that lands inside both — at the lowest cost per day — is the one you buy.
A base page can claim slower diffusion. Only your scale and a blind room score show whether it is slow enough, and strong enough, for the product you are selling.

Speed has three dials — the base is only one

How fast a reed diffuser empties depends on the carrier, the reeds and the surroundings. The carrier matters: a carrier that evaporates readily leaves the reed surface faster than one that does not. The reeds matter as much: more reeds expose more surface, and CSI's reed page says so directly — more reeds for stronger throw and faster diffusion, fewer for a subtler, longer-lasting result. The surroundings matter too: warm, moving air speeds evaporation, and the same bottle can empty noticeably faster in May than in January.

The three speed dials · cost to change · owned in depth by
What changes how fast a 100 ml product empties
Dial Faster Slower Cost to change Owned by
Carrier A more readily evaporating carrier A carrier whose page claims slower diffusion, e.g. Longevity A new base — from ₹1,099.00 / 500 ml 7930, 7929
Reed count More reeds (e.g. 8) Fewer reeds (e.g. 6 or fewer) ₹9.00 per white reed (50+ rate) 7971
Surroundings Warm room, airflow, summer Cool room, still air, winter Free — but not yours to control after sale 7975, 7976
Bottle opening Wider opening is commonly described as releasing more Narrower opening or a reducer (not a CSI item) A different bottle 7976
Load Changes strength more than speed; very high loads can change flow — Oil cost 7948

That table is why this test includes a reed-count arm. If the slower base, with two extra reeds, gives you the same g/day as the neutral base with its standard count — and a better score — you have learned how to place the same product anywhere on the speed curve by reed count alone. If the slower base with more reeds is still slower and scores no worse, it is the base for a long-life product. If it is slower and weaker, it has bought life at the cost of strength, and you have a decision to make.

The common mistake: judging speed by eye. A maker looks at two bottles after a week, sees one level a little lower, and calls it the faster base. A millimetre on a 120 ml bottle is a few grams; differences in fill, reed pack and placement can easily make that much difference. Fix: weigh every bottle with its reeds on fixed days and calculate g/day from day 3 to day 21. Levels are for photographs, not decisions.

The round: slower-claim base, two reed counts, neutral control

Ten bottles: three arms of three plus a capped hold-back. Every bottle holds 100 ml of blend — 100 g at the example density — at 22%: 22.0 g of oil and 78.0 g of base, weighed in.

Weigh 100 ml of each base firstBefore mixing, pour 100 ml of each base into a Silicon Measuring Beaker 100 ml or a measuring container on the Weighing Scale and note the weight. You need about 491 g of Longevity for arms B and C; one 500 ml covers that only if the base weighs at least 0.983 g per ml. If yours is lighter, buy a second 500 ml or drop one bottle from arm C.

Mix by weight, rest 24–48 hoursTare each bottle, add 78.0 g of base and 22.0 g of oil, cap, invert ten times. Rest every bottle 24–48 hours as the base pages require, checking clarity against white and black cards at 0, 24 and 48 hours.

Day 0: reeds and weights6 reeds in B1–B6, 8 in B7–B9, none in B10. Weigh each with reeds. Longevity's page asks for 2–3 hours before the first flip and Pure Performance's for one hour; to keep the arms comparable, flip every bottle once at three hours and write it down.
4
Place and keep it stillOne shelf, mixed order, equal spacing, away from fans, AC vents, windows and doors — Longevity's page also says to keep it away from strong air currents. Log the room temperature at every weighing.

Weigh on fixed days, score blindWeigh on days 1, 3, 7, 14, 21 and 28 at the same time of day. Score blind on days 7, 14 and 21 in the room the product is for: a helper places one bottle at a time for a fixed period while you wait outside.

Plot each bottle on the map at the top of this page: g/day along the bottom, average blind score up the side, with your life line and strength line drawn in. An arm "lands in the zone" only if all three of its bottles do. If arm B is in the zone and arm A is to the right of the life line, the slower-claim base has done what its page says for this oil. If arm A is already in the zone, you do not need a slower base for this product. If B is below the strength line but C is in the zone, the slower base needs more reeds to be strong enough — and you now know the reed count to sell it with.

Test in the season you sell into
A bottle that lands in the zone in a cool October room may sit to the right of the life line in May. If you sell year-round, repeat the round in your warmest month, or place a second set of bottles somewhere warm and still for comparison. Too fast in summer and too weak in winter show how to read temperature into the result.

Cost per day: does the slower base pay for itself?

A dearer base that lasts longer can be cheaper per day. The arithmetic says exactly how much longer it has to last.

Longevity costs ₹1,296.00 per 500 ml against ₹1,099.00 for Pure Performance. At production rates — Palo Santo at its 1 kg rate of ₹6.02 per gram, each base at its 500 ml price at the example 1.00 g per ml — the liquid in one 100 ml bottle costs ₹303.84 in Pure Performance and ₹334.57 in Longevity, a ratio of 1.101. So Longevity matches the neutral base on cost per day of use if it lasts at least 10.1% longer. Anything beyond that is a saving per day for your customer, and a longer-life claim for you.

Arithmetic only — the days are examples, not measurements · liquid cost per day, 100 ml bottle at 22%
What Longevity must achieve to match Pure Performance per day
If the Pure Performance bottle lasts PP liquid cost per day Longevity cost per day at the same life Longevity must last at least
30 days ₹10.13 ₹11.15 33.0 days
45 days ₹6.75 ₹7.43 49.6 days
60 days ₹5.06 ₹5.58 66.1 days

Bottle (₹106.20) and reeds (6 white at ₹9.00, ₹54.00) are the same for both routes, so they do not change the comparison. Two more lines matter commercially. First, a longer-life claim is only worth something if you can make it truthfully: use your measured days in the room you tested, and say so. Second, a customer who finds the bottle quiet in week one may not wait for week six. That is why the strength line sits in the target zone as firmly as the life line. Is a dearer base worth it at a lower load? explores the case where a base costs more but lets you use less oil, and the most economical fragrance percentage sets load against life and throw.

Sell the life you measured, in the room you measured it, at the strength your blind panel scored.

Write the base, reed count, measured g/day, projected days and blind scores on the product's formula sheet, with the room temperature range. If you later sell a second size — a 50 ml version, for instance — repeat the round; the target zone moves with fill weight, and a reed count that works in 120 ml rarely transfers unchanged. Comparing two bases on five measures gives the full comparison sheet.

Why trust this guide

CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished diffusers. The easy answer for a base seller is "buy the long-life base". This page points out that no CSI base publishes an evaporation rate, treats Longevity's slower-diffusion line as a claim to test, shows how much longer it must last to justify its price, and puts a reed-count arm in the test because it is often the cheaper fix.

Base, reed, bottle and tool prices are CSI live pricing, pulled 14 October 2026; fragrance-oil prices are CSI live pricing, pulled 24 September 2026, stock re-checked 14 October 2026. Every blend split, ml-to-gram conversion, per-bottle cost, kit total and cost-per-day figure on this page is computed and shown to two decimals so you can check it. CSI publishes no composition, density, viscosity or evaporation data for its bases, so every density used here is a labelled example and every g/day figure is either yours to measure or a labelled arithmetic grid.

Bottle counts per arm, weighing days, the clarity checkpoints, the room-scoring protocol and the decision thresholds are labelled working practices, not industry standards — none exists for reed diffusers. The 45-day life target, the score-3 strength line, the 1.00 g per ml density and the day counts in the cost-per-day table are labelled examples; the 100 ml fill is the reader's product size.

Frequently asked questions

How long should a 100 ml reed diffuser last?
There is no standard. It is whatever your measured grams per day allow: fill grams ÷ g/day. A 100 g fill losing 2.22 g a day lasts about 45 days; losing 3.33 g a day, about 30. Measure it in the room you sell for.
Which reed diffuser base lasts longest?
CSI publishes no longevity data. Longevity Base's page claims slower "cold diffusion" and Depth mentions "slow diffusion"; test either against a neutral base by weighing the bottles from day 3 to day 21.
How do I make my reed diffuser last longer?
Use fewer reeds, keep it away from airflow and heat, and consider a base whose page claims slower diffusion — then measure grams per day to confirm the change. Check it still passes a blind room score.
Does a slower reed diffuser base smell weaker?
Often, because less liquid leaves per day. That is why the test includes a slower base with more reeds: it can recover strength while keeping a longer life.
How many reeds for a 100 ml reed diffuser?
CSI's reed page suggests 6–8 for a 50–100 ml bottle, more for stronger and faster diffusion, fewer for subtler and longer-lasting. Test two counts and weigh the bottles.
How do I measure reed diffuser evaporation rate?
Weigh the bottle with its reeds at the same time of day on fixed days. Grams lost between day 3 and day 21, divided by 18, is the average g/day after the reeds have loaded.

About this guide: Written by the CANDLEMAKINGSUPPLIESINDIA team. The target-zone method, cost-per-day comparison and decision rule apply to any base from any supplier; the products named are CSI's.

Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Eco Candle Wicks, Premium Candle Wicking Needle and Bamboo Wick Holder. They are general product reviews, not assessments of the guidance set out here. Names, star ratings, dates and products are as recorded by Judge.me and wording is unedited. "Verified buyer" appears only on the three reviews Judge.me recorded as verified — Monika Deep, Subhankar Roy and Sneha Tamang; the reviews from Ashwini, LJ and Lalitha Jagan are published but not recorded as verified, and carry no badge.

Fragrance oils — CSI live pricing, pulled 24 September 2026, stock re-checked 14 October 2026: Palo Santo Fragrance Oil ₹106.20 / 15 g, ₹300.90 / 50 g, ₹601.80 / 100 g, ₹3,009.00 / 500 g, ₹6,018.00 / 1 kg.

Non-price figures and assumptions: Load convention: fragrance load is a share of the total blend by weight (oil g = blend g × L; base g = blend g × (1 − L)). Where millilitres are turned into grams, the page uses a labelled example density of 1.00 g per ml with a ±5% sensitivity (0.95–1.05 g/ml) — weigh 100 ml of your own blend to get yours; the 120 ml and 50 ml bottle sizes are listing sizes, not fill lines. Worked example: 100 ml fill in the Gold 120 ml bottle = 100 g at the example density; at 22% = 22.0 g oil + 78.0 g base. Life targets 30, 45, 60, 90 days → maximum g/day = fill g ÷ days. Working practices: 3 bottles per arm plus 1 capped hold-back, 6 or 8 white reeds, one flip at 3 hours for every bottle, 5% allowance, weighings on days 0–28, blind scores on days 7, 14 and 21, room temperature logged. One 500 ml of Longevity covers arms B and C only at a density of 0.983 g/ml or more. Cost per day uses the oil's 1 kg rate and each base's 500 ml price at the example density; Longevity/Pure Performance liquid-cost ratio = 1.101. What CSI's base pages state (quoted as claims to test, not CSI measurements): every base page gives a 10–30% fragrance range of the total blend and a 24–48 hour rest before bottling; Pure Performance — neutral, "no added fixatives, no complex enhancements", all families, "start at 10% … up to a maximum of 30%", "20% recommended", "typical working blend 75% base + 25% fragrance", "flip reeds after the first hour"; Longevity — oriental/amber, woody, resinous/balsamic, spicy and gourmand families, slower "cold diffusion", avoid light florals, fresh citrus and aquatics, "heavy oils like oud can cloud at maximum load in some bases", 2–3 hours before the first flip; Lift — "perfumery-grade", floral, citrus, green and fruity families; Depth — warmth, roundness, "slow diffusion", chypre, leather, smoky and rich gourmand, "stabilises tricky sweet and spicy fragrance oils"; Softness — soft florals, powdery/musky and light gourmand. Marketing lines such as "performs in Indian climates", "no separation" and "even wicking" are claims to test. Some base pages mention rattan; CSI sells fibre reeds, not rattan. CSI publishes no composition, density, viscosity, evaporation rate, flash point or shelf life for any base, and no throw, evaporation or longevity data for any base, oil or reed; reed diameter, bottle neck size and fill line are not published. No CSI base is ranked above another on this page — the five are separated only by what their own pages say they are for. Material costs exclude labour, labels, boxes, freight and GST. Diwali 2026 falls on Sunday 8 November.
