Temperature · Flash point explained
Flash point is the most misread number on a fragrance oil's paperwork. It does not tell you when to add the oil, when it will evaporate, or when it will burn in the jug. It tells you when its vapour can briefly ignite if a flame is present. This page explains the measurement, shows where it belongs, and sets out a safer way to heat wax.
Two things
flash point (a safety property of the oil, on its MSDS) and the addition window (a process property of the wax, from the wax maker) — never the same number
Quick answers — read this first
Does a fragrance oil's flash point tell me when to add it to wax? No. They are two different things. Flash point is a safety measurement of the oil's vapour. The temperature at which you add oil to wax is set by the wax maker for that wax. The only CSI figure on record is CSI's CSI 464 guidance, 80–90°C — confirm on the product page.

What does flash point actually measure? The lowest temperature at which vapour above the liquid can briefly ignite when a flame or spark is passed over it, in a standard laboratory test. It says nothing about how the oil dissolves in wax or how the candle smells. See what it measures.

Does oil evaporate or burn off above its flash point? Not in the way makers fear. Flash point is not a boiling point and not an evaporation threshold. Oil evaporates gradually at many temperatures. I'm Worried That Adding Fragrance to Hot Wax Will Burn Off the Scent — How Much Fragrance Actually Evaporates During Normal Candle Production? covers how to measure loss in your own process.

Where do I find an oil's flash point? On its MSDS, usually in the physical and chemical properties section. No per-oil flash point is published in the data behind this page. Ask CSI on WhatsApp for the MSDS.
The short answer
Definition: Flash point: the lowest temperature at which a liquid's vapour can momentarily ignite from an ignition source under standard test conditions. A safety and transport property.
Not the same as: The addition window (set by the wax maker for the wax), the boiling point, or the point where scent is lost. CSI 464: 80–90°C melt and pour per CSI's guidance; other waxes: the wax maker's instructions.
Use it for: Storage away from heat and flame, handling, shipping, and choosing a heat source without an open flame. Several oils on one process.

Straight answer
Does a fragrance oil's flash point tell me the temperature at which I should add it to candle wax, or are these two different things?
They are two different things. Flash point is the lowest temperature at which the vapour above a liquid can briefly catch fire when a flame or spark is passed over it, measured in a standard laboratory test and printed on the oil's MSDS. It exists for safety: storage, handling and transport. The temperature at which you add oil to wax is a process figure, and it belongs to the wax. The wax maker tested how their wax takes up oil and sets, and states a window for it. The only CSI figure on record is CSI's CSI 464 guidance, 80–90°C — confirm on the product page; for any other wax, follow the wax maker's instructions. Flash point is also not a boiling point or an evaporation threshold, so an oil does not suddenly "burn off" above it. What it does tell you is to keep open flames and sparks away from warm oil and scented wax. That is the practical lesson: use a heat source without an open flame, such as a double boiler or an electric melter, add oil off direct heat, and keep each oil's MSDS on file. No per-oil flash point is published in the data behind this page, and we will not quote one. Ask us on WhatsApp for the MSDS.
One line: flash point tells you how to keep the oil safe; the wax maker tells you when to add it.
If you heat wax in a pan on an open flame, the most useful thing flash point can teach you is to stop. A Mini Electric Wax Melter (1 litre, ₹2,360.00) removes the open flame from the melting step. The two-oil test on this page uses Neroli 50 g (₹342.20) and Saffron Cedarwood 50 g (₹354.00) in CSI 464.

What flash point actually measures

Flash point is a fire-safety test. It answers one question: at what temperature is there enough vapour above this liquid for a flame to flash across it?

In the standard test, a small sample of the liquid is heated in a cup at a controlled rate. At intervals, a small flame or spark is passed over the surface. The flash point is the lowest temperature at which the vapour above the liquid ignites in a brief flash. The liquid itself does not keep burning at that point; that happens at a higher temperature, usually called the fire point. The test is designed so that different liquids can be compared for how easily their vapours ignite, which is what storage, transport and workplace safety rules care about.

There are two broad families of method. In a closed-cup test the vapour is trapped under a lid, so it builds up and the result is generally lower. In an open-cup test the vapour can drift away, and the result is generally higher. That is why the MSDS usually names the method beside the figure, and why two documents for similar oils can show figures that are not directly comparable. For candle makers, the key point is simpler: whichever method is used, the number describes vapour and ignition, not dissolving, setting or scent.

What it describes When the oil's vapour can briefly ignite from a flame or spark When the wax takes up fragrance oil well and sets properly

CSI figure on record None published in this data — ask for the MSDS CSI 464: 80–90°C melt and pour, per CSI's guidance

Put the two side by side and the confusion becomes easy to see. Both are temperatures. Both appear in conversations about adding fragrance to hot wax. But they are measured by different people, for different reasons, on different materials. One is a property of the oil in a lab cup with a flame. The other is a property of the wax in your jug.

Look for the method next to the number
When you read a flash point on an MSDS, check whether it says closed cup or open cup, and which standard. If you compare two oils, compare figures from the same method. And whatever the number is, file it under safety, not under process.

Four things flash point is not

Most of the worry about flash point in candle-making comes from reading it as something it is not. Here are the four common misreadings, and what is actually true.

General candle-making and chemistry knowledge · not CSI measurements
What makers think flash point means, and what it does mean
Misreading Why it is wrong What is actually true
"Add the oil below its flash point" Flash point was not measured in wax and says nothing about how oil dissolves Add the oil within the wax maker's window, for every oil
"Above the flash point the scent burns off" Flash point is not a boiling point or an evaporation threshold Evaporation happens gradually at many temperatures and depends on time and surface area. Measure it
"Above the flash point the wax will catch fire in the jug" Ignition needs an ignition source in the vapour Keep open flames and sparks away from warm oil and scented wax
"A higher flash point means a stronger or better candle oil" Flash point describes vapour ignition, not throw Throw depends on load, wick, cure, room and the oil itself — found by testing

The third row is the one worth dwelling on, because it is the real safety lesson. Warm fragrance oil and scented wax give off vapour. If a flame is nearby, that vapour is a hazard, and the flash point on the MSDS tells you roughly how readily it can ignite. The answer is not to change your addition temperature. It is to remove the flame: melt in a double boiler or an electric melter, add the oil away from any burner, and never test-burn candles in the same space as open bottles.

The rule that feels safe and is not. A maker decides to add every oil below its flash point, and for oils with a lower figure that means adding oil to wax that is already thickening. The oil does not incorporate, the candles sweat, and the maker still has a pan on an open flame. The rule protected nothing and created a new fault. Swap it for two rules that work: the wax maker's window for the process, and no open flame for safety. I Added Fragrance Oil at a Lower Temperature Because I Was Afraid of Evaporation — Why Did It Not Seem to Bind Evenly into the Wax? covers what happens when oil goes into wax that is too cool.

Reading the MSDS: where flash point lives

An MSDS looks like a wall of text, but a candle maker needs only a few sections of it.

A Material Safety Data Sheet (often called an SDS) follows a standard layout of numbered sections. The exact numbering can vary with the format the supplier uses, but the content is broadly the same. The table lists the parts that matter in a candle workshop. We supply MSDS documents for our oils on request, on WhatsApp.

Common MSDS layout · check the headings on the document you receive
The parts of an MSDS a candle maker actually uses
Section (typical) What it holds What you do with it
Identification Product name, supplier, emergency contact Match it to the bottle; file by product name
Hazards identification Hazard statements and pictograms Know which oils need extra care; label your storage
First-aid measures What to do after skin or eye contact Pin it near your workbench
Handling and storage How to store and handle safely Closed bottles, away from heat, flame and sunlight
Exposure controls / personal protection Gloves, ventilation Ventilate the workshop; wear gloves when weighing oils
Physical and chemical properties Flash point (with method), appearance, other properties Read flash point here — for safety, not for process
Transport information How the product may be shipped Relevant if you ship oils or resell them

Two things are not on an MSDS and should not be looked for there. The first is an addition temperature for candle wax, which belongs to the wax maker. The second is an IFRA use level, which comes from a separate IFRA certificate. Ask for both documents when you order: the MSDS for handling and the IFRA certificate for how much of the oil may be used in a given product type. For a wider list of what to ask a supplier, I Need the Same Candle Fragrance for Several Years — What Should I Ask a Supplier About Batch Consistency, Availability and Reformulation Before Building a Bestseller Around It? and I Need One Fragrance Oil Supplier for Dozens of Candle Scents — How Do I Compare Performance, Consistency, Documentation, Bulk Pricing and Availability Before Consolidating Purchasing? cover it.

The CSI principle
File flash point with safety, not with your recipe.
Keep every oil's MSDS in one folder beside your first-aid kit and storage rules. Keep your process sheet — wax maker's window, stir, pour — in another. When the two numbers never share a page, nobody on your team will mistake one for the other.

Using flash point properly: a safer heat setup

If flash point has one practical message for a candle workshop, it is this: warm oil and scented wax should not share space with an open flame. Here is a setup that follows that message without inventing any temperature. It is general safety practice; your local rules and each oil's MSDS take precedence.

1
Melt without an open flameUse a double boiler on a controlled heat source or an electric melter such as the Mini Electric Wax Melter (1 litre, ₹2,360.00). The melter is listed by volume; melted wax is lighter than water, so a litre holds less than a kilo of it. Fill only to the maker's line.
2
Bring the wax into the wax maker's windowStir, then read a Pen Thermometer in the middle of the melt. For CSI 464, CSI's guidance is 80–90°C melt and pour; confirm on the product page. For any other wax, use the wax maker's instructions.
3
Weigh the oil away from the heatWeigh the oil on a separate bench, cap the bottle and put it back on the storage shelf before you take the oil to the wax.
4
Add oil off direct heatPour the wax into a pouring jug or switch the melter off, then add the oil and stir. That keeps warm scented wax away from any heating element while it gives off the most vapour.
5
Ventilate, and keep flames outWork with a window open or a fan moving air out of the room. Keep matches, lighters and test candles out of the pouring area.
6
Burn-test elsewhereLight test candles in a different room from open oil and warm wax. It keeps the one deliberate flame in your process away from the vapour that flash point is about.
Argued against our own interest, plainly. A melter is a real expense, and a double boiler on a controlled heat source does the same job of keeping flame away from wax for far less. If you are melting a kilo or less at a time and already have a double boiler, you do not need to buy our melter. Buy it when batch size, convenience or temperature control makes the difference to your process.

A two-oil test on one process

To see that flash point does not change the process, run two different oils through the same one. The test uses three 200 g candles per oil at an 8% load of the finished weight: 48 g of oil and 552 g of CSI 464 per oil, one 600 g melt each. Neroli is a bright citrus-floral; Saffron Cedarwood is a warm, spiced wood. Their MSDS documents may show different flash points. The process stays the same for both: CSI 464's 80–90°C melt and pour per CSI's guidance, the same stir, the same pour.

3 × 200 g per oil at 8% · Neroli 50 g ₹6.84/g · Saffron Cedarwood 50 g ₹7.08/g · CSI 464 ₹507.40/kg · wick and jar verified 10 September 2026

Saffron Cedarwood Fragrance Oil 48 g ₹339.84
Luxury Soy Wax CSI 464 1,104 g (552 g × 2) ₹560.17
Eco Candle Wicks Thin C1 6 × ₹5.90 ₹35.40

Material cost excludes labour, packaging, freight and GST. After curing to the same labelled checkpoint, burn one of each oil and compare. If one oil needs attention, it will almost certainly be its load, wick or cure, which is where I'm Using Several Fragrance Oils with Different Flash Points — Should I Change My Wax Mixing Temperature for Every Fragrance? points you. None of those changes involve its flash point.

Frequently asked questions

What is flash point in fragrance oil?
The lowest temperature at which the vapour above the oil can briefly ignite when a flame or spark is passed over it, in a standard laboratory test. It is printed on the oil's MSDS and used for storage, handling and transport safety.
Should I add fragrance oil at its flash point?
No. Flash point is not an addition temperature. Add the oil within the wax maker's stated window for your wax. The only CSI figure on record is CSI 464's 80–90°C melt and pour, from CSI's own guidance; confirm on the product page.
Does fragrance oil burn off above its flash point?
Flash point is not a boiling or evaporation point. Oil evaporates gradually at many temperatures, and the amount depends on temperature, time and open surface area. I'm Worried That Adding Fragrance to Hot Wax Will Burn Off the Scent — How Much Fragrance Actually Evaporates During Normal Candle Production? shows how to weigh your own loss.
Is it dangerous to heat wax above the fragrance oil's flash point?
The hazard is an ignition source near warm oil vapour. Melt without an open flame (double boiler or electric melter), add oil off direct heat, ventilate and keep flames away from the pouring area. Read each oil's MSDS for its own handling guidance.
What is the difference between closed-cup and open-cup flash point?
In a closed-cup test the vapour is trapped under a lid and the result is generally lower; in an open-cup test vapour can escape and the result is generally higher. Compare oils using figures from the same method.
Where can I get the flash point of a CSI fragrance oil?
From the oil's MSDS, which CSI supplies on request. Message us on WhatsApp with the oil names. Flash points are not published in the data behind this page.
